Abstract: The present invention provides a wood-type club constituted such that the toe-down effect and the covering effects of the head can be more reliably suppressed. Attitude-correcting portions (30, 31) extending from the impact face (11) side to the back (14) side of the head are provided in at the least the toe (T) side and the heel (H) side of the head relative to a center line passing longitudinally through the head center of gravity in either the side parts (15, 16) or the sole (13) of the head (10), and are formed such that a portion of the highspeed airflow impacting the head at downswing is captured by at the least two attitude-correcting portions, either maintaining the head in a proper attitude, or correcting the head to a proper attitude.

Abstract: In a door mirror in accordance with the present invention, at a connecting portion near a driver's seat or a passenger seat, an opposing portion which is a boundary between the connecting portion and a lid is exposed on the surface of a visor at a side toward the substantial rear of a vehicle. Therefore, even if steps are formed at the opposing portion and slight irregularities are thereby formed on the surface of the visor, air flow does not flow over the opposing portion, or orientation of air flow is not rapidly changed or turbulence is not generated over or below the opposing portion. In this way, noise such as wind noise generated near the connecting portion can be reduced or eliminated.

Abstract: In a door mirror assembly for a vehicle, a case is supported at a door mirror stay provided at a vehicle door and mounted to a door mirror visor, whereby the door mirror visor is disposed above the door mirror stay. An overlap portion provided at the case and an overlap portion provided at an opening of the door mirror visor are overlapped one above the other and mounted, and a gap between the opening of the door mirror visor and the lower part of the case is thus stopped. Therefore, generation of wind noises caused by wind entering through the gap between the opening of the door mirror visor and the lower part of the case while a vehicle is in motion can be prevented.

Abstract: A reflecting mirror is obtained which prevents double images from being formed and provides sufficient the hydrophilic property. The hydrophilic coating is approximately 15 nm in thickness and the photocatalytic coating between the hydrophilic coating and the glass substrate is approximately 240 nm in thickness. This setting of dimensions reduces the surface optical reflectance of light having a wavelength ranging from approximately 550 nm to 580 nm. This also reduces the deterioration of the photocatalytic action caused by the diffusion of sodium ions contained in the glass substrate into the photocatalytic coating. Furthermore, the aforementioned setting of dimensions turns the color of surface reflected light to whitish. Even when images formed by the surface reflected light or images formed by reflected light from the reflecting film interfered by surface reflected light are viewed, the after-image thereof hardly remains.

Abstract: In a belt-driven auxiliary equipment driving apparatus for vehicle engines, a one-way clutch-integrated pulley is disposed which includes a bearing for relatively rotatably supporting inner and outer rings and a clutch mechanism for effecting or blocking torque transmission between the inner and outer rings by changing the tilting direction of sprags according to the direction of relative rotation of the inner and outer rings. In such a case, a cage of the clutch mechanism is connected to a cage of the bearing. The cage of the bearing is rotated in the same direction as that of relative rotation of the outer ring at a relative rotational speed lower than that of the outer ring, and as a result, the relative speed of bodily movement of each sprag around the inner ring is made slower than the relative rotational speed of the outer ring. During idling of the inner and outer rings, each sprag thereby slides also on the outer ring and the speed of slide of each sprag on the inner ring is lowered.

Abstract: A buckle that can be manufactured at lower cost and is not unlocked even when a tongue plate is pushed in a locked state is obtained. An intermediate arm 60 is fixed to a lock spring 54 attached to a button 28. Facing walls 68 of leg portions 66 of the intermediate arm 60 face distal ends of horn pieces 26 of an ejector 22. In the locked state, a predetermined clearance 72 is formed between the facing walls 68 and protrusions 70 of the horn pieces 26. Accordingly, even if a tongue plate 20 is moved further in the direction of the arrow A, the facing walls 68 are not moved in the direction of the arrow A. The button 28 is not moved in an unlocking direction (the direction of the arrow A), either, and movement of a latch 48 in a disengaging direction (the direction opposite to the arrow B) is certainly prevented. As protrusions 38 can be formed in a small size, a buckle 10 is formed in a small size, and the buckle 10 can be manufactured at lower cost.

Abstract: There is provided a pretensioner which can as a whole be made smaller. A rack and pinion type pretensioner is disposed outside a second leg plate of a webbing take-up device. A driving mechanism of the pretensioner includes, as principal components, a piston formed as a rack bar, and a pinion. The pinion includes a toothed portion and a clutch portion, and is directly connected to a winding shaft. Accordingly, as compared with a conventional system in which intermediate gears are disposed between the pinion and the rack bar, the pretensioner can as a whole be made smaller both in radial and axial directions thereof.

Abstract: A spring having four urging legs is fixed in a stay of a mirror, and retention pawls corresponding to the urging legs are formed at a base fixed within a passenger compartment of a vehicle. The urging legs engage with the retention pawls so that the stay is held at the base at a predetermined load. Because the four urging legs are provided on the spring, an urging force of the respective urging legs can be made small and bending of the urging legs is unobstructed by other members. Accordingly, when a load of predetermined value or greater acts upon the mirror, the urging legs corresponding to the direction in which the load acts slide and the engagement between all of the urging legs and the retention pawls is released. The mirror is allowed to fall regardless of the direction in which the load acts.

Abstract: A reflection preventing treatment is performed with respect to an edge face of a light shielding blade. The blade is composed of a film material made of a polyester, and is formed into a predetermined shape as a base piece. A flat face portion of the blade is capable of shielding an incident light, and an edge face portion is present in perpendicularly crossing to the flat face portion. An inner edge face of an aperture opening is included in this edge face portion. In order to form the blade, at first the base piece is punched from the film material in a predetermined shape. Subsequently, a chemical etching is applied to the edge face portion of the punched base piece so as to roughen the edge face portion. Accordingly, it is possible to suppress an unnecessary reflection of the incident light at the edge face portion. It is possible to evenly and efficiently roughen the inner edge face of the aperture opening by collecting a multiplicity of punched base pieces and dipping them in an etching solution.

Abstract: In a vehicle door mirror device, a bracket is divided into a frame and a case member. Thus, the frame and the like for a vehicle right side and for a vehicle left side can both hold a mirror at a vehicle rear side thereof. A mounting hole and a supporting hole of a case member are provided to be symmetrical with respect to a vertical plane which passes through a widthwise direction center of the case member. Thus, even if a common case member is used both for a vehicle right side and for a vehicle left side by left and right sides of the case member being reversed, the mounting hole of the case member can be mounted to the frame and the like for the vehicle right side and the vehicle left side.

Abstract: A one-way clutch is arranged so that a plurality of intermediate members, which are each retained in a cage, each wedge between inner and outer rings when the inner and outer rings relatively rotate in a locking direction and each rock opposite to the direction of the wedging when the inner and outer rings relatively rotate in an idling direction, are pressed in the direction of the wedging by spring members. In this one-way clutch, each spring member includes a pair of coil springs that are juxtaposed to align in an axial direction of the inner and outer rings, are retained at one ends thereof by the cage and resiliently contact at the other ends thereof with the intermediate member. The one ends of both the coil springs are connected together through a connecting portion. The coil springs and the connecting portion are formed of a single wire.

Abstract: In an electromagnetic actuator, a rotor composed of a permanent magnet is mounted rotatably in two directions between a first end position and a second end position via an intermediate position. A coil is wound around the rotor to rotate the rotor in an energizing state where an electric current is applied to the coil. An auto-retaining device is provided for retaining the rotor at one of the intermediate position, the first end position and the second end position under a non-energizing state where the electric current is not applied to the coil. The auto-retaining device has an elastic member that regulates the rotor at the intermediate position by a mechanical elastic force, a first magnetic member that is opposed to the permanent magnet and that retains the rotor at the first end position by a magnetic attractive force, and a second magnetic member that is opposed to the permanent magnet and that retains the rotor at the second end position by a magnetic attractive force.

Abstract: When a shift lever is moved in the transverse direction of a vehicle to a “P” range, a driving lever which is pressed by the shift lever is moved to a released position and a slide member, which is connected to the driving lever via a wire connecting mechanism, is moved to a position at which a lock pin is separated from a lock cam. Further, when the shift lever is taken out of the “P” range, the driving lever is moved to a restricted position due to the urging force of a torsion spring, and the slide member is moved to a position at which the lock pin is engaged with the lock cam. In this way, mechanical operating force is directly supplied to a key interlock mechanism such that the structure of the key interlock mechanism is simplified.

Abstract: An electrostrictive micro-pump is provided for controlling a fluid flow through a cannula or other narrow liquid conduit. The micro-pump includes a pump body having a passageway for conducting a flow of fluid, a pump element formed from a piece of viscoelastic material and disposed in the passageway, and a control assembly coupled to the viscoelastic material for electrostatically inducing a peristaltic wave along the longitudinal axis of the pump element to displace fluid disposed within the pump body. The control assembly includes a pair of electrodes disposed over upper and lower sides of the pump element. The lower electrode is formed from a plurality of uniformly spaced conductive panels, while the upper electrode is a single sheet of conductive material. A switching circuit is provided for actuating the conductive panels of the lower electrode in serial, multiplex fashion to induce a peristaltic pumping action.

Abstract: Extruded sections of synthetic fibers extruded from a side face of each rib in a V-ribbed belt are plastically deformed in the shape of sectors gradually broadened toward their distal ends. The extruded sections of the synthetic fibers are not heated beyond their melting point during a grinding process so as to be kept unmelted. The extruded sections of the synthetic fibers are raised from the side face of the rib so that microscopic unevenness is formed over the side face of the rib. The synthetic fiber is formed of nylon with a filament diameter of 20 &mgr;m or more.

Abstract: In a pretensioner, an axial direction of a generator accommodating portion is inclined from a direction which is orthogonal to an axial direction of the cylinder main body toward the cylinder main body. As a result, another axial direction end portion of the generator accommodating portion is positioned closer to the cylinder main body side and the dimensions of the pretensioner along the orthogonal axial direction of the cylinder main body becomes small. In addition, at a bottom portion side of the cylinder main body, an open space is generated along the orthogonal direction of the cylinder main body and therefore the pretensioner becomes more compact. Moreover, since the generator accommodating portion and the cylinder main body are connected such that a center axis of the generator accommodating portion is skewed with respect to the center axis of the cylinder main body, a large area can be secured for the opening into the cylinder main body while a compact structure is maintained.

Abstract: Short aramid fibers extruded from a side face of each rib in a V-ribbed belt are formed in curled shape. The root portions of the extruded short aramid fibers are raised from the side face of the rib. The tip portion of each extruded short aramid fiber is bowed in a direction different from a bowing direction of its medial portion. The extruded sections of the short aramid fibers are different in bowing direction from one another to decentralize the orientation thereof.

Abstract: A datum plane setting device capable of generating two or three reference planes is provided. The device includes a motor 6, rotary bodies 3 (3x, 3y, and 3z) which rotate in accordance with rotary driving of said motor via a direct drive and belt drive, rotary heads 8 formed on the tip end portions of said rotary bodies 3, laser emitting portions 9 which are accommodated inside said rotary heads 8 and rotate with said rotary heads 8 as one body. A power source supplies current for the motor 6 and laser emitting portions 9. A casing 2 accommodates the motor 6, rotary bodies 3, power source 5, supporting members for horizontally supporting said casing, and a level 27 for confirming a level of said casing. The laser emitting portions 9 are constructed so that current is supplied from the power source 5 via current-supplying brushes 1501 which contact guiding paths provided around the rotary bodies 3.

Abstract: In pressing a slack-side span of a V-ribbed belt, entrained about a crank pulley variable in rotational speed, auxiliary pulleys and an idler pulley, with an auto tensioner, thereby automatically balancing tension of the belt, the damping coefficient DI of the auto tensioner is set in accordance with the modulus of longitudinal elasticity of the belt. For example, when the modulus of longitudinal elasticity of the belt is at least 9800 N/100% rib and less than 29400 N/100% rib, the damping coefficient DI of the auto tensioner is set at at least 20% and less than 100%. In this manner, even if the rate at which the auto tensioner absorbs elongation of the belt is as extremely small as 0.3 to 1.0 mm/deg, a rocking motion of the auto tensioner can be avoided thereby reducing the occurrence of a slip or a frictional sound of the belt and the occurrence of abrasion and frictional sounds of friction members, such as an insert bearing and a thrust washer, of the auto tensioner.

Abstract: An airbag apparatus is obtained in which a pad cover can be securely supported onto a base member and the manufacturing work is also facilitated. Hook-shaped engagement protrusions or tongue shaped insertion portions are formed interchangeably on a side wall portion of a bag holder which fixes an inflator and a bag. Correspondingly, engagement openings or support walls are formed interchangeably on the mounting portion of the pad cover which unfolds when the vehicle decelerates rapidly. When both parts are fit together, the engagement protrusions are engaged with the engagement openings and the insertion portions are inserted between the support walls and the mounting portions. As a result, when the pad cover unfolds, the pad cover does not come off from the bag holder and the manufacturing work is facilitated because the support walls and the mounting portions which hold the insertion portions are formed of a resin.
