  • Patent number: 6536094
    Abstract: Apparatus and methods for reducing the likelihood of damage to wire leads of undulated coils for dynamo-electric machine stators are provided. The invention provides a rotating winding head equipped with a coil former that has a wire gripper and an initial wire lead slot. The gripper retains the initial wire lead. The slot permits the initial wire lead to be fed to the gripper from a stationary wire source. The gripper maintains the initial wire lead in a predetermined plane of the coil and can secure the initial wire lead in the plane in which the final lead wire will eventually be disposed. The gripper also rotates the initial wire lead into radial alignment with a lobe of the undulated coil. Once installed in a stator, the initial and final wire leads can both be disposed along the outer radius of the coil and are thus protected from interference with a rotor that is destined to rotate within the stator.

  • Patent number: 6536108
    Abstract: In a production apparatus (1), after rear holders (7a, 7b) and a housing body (8) are molded by molding die cavities, slides (11a, 11b) are moved apart from the housing body (8). Then, cylinders (16a, 16b) are driven to move the rear holders (7a, 7b), holders (13a, 13b) and the slides (11a, 11b) together with slide plates (14a, 14b), so that the rear holders (7a, 7b) are located in opposed relation to the housing body (8). Then, cylinders (19a, 19b) are driven to move the rear holders (7a, 7b) toward the housing body (8), thereby provisionally retaining the rear holders (7a, 7b) on the housing body (8). Therefore, the amount of movement of the slides (11a, 11b) is small, and it is not necessary to provide any space for holding the slides (11a, 11b), moved into their respective stand-by positions, and therefore the small-size design of the production apparatus can be achieved, and also the production efficiency can be enhanced.

  • Patent number: 6536115
    Abstract: The present invention provides a knife with a replaceable blade which is spring-biased in the retracted position. The knife is designed such that the blade can only be extended by exerting a downward force and by turning the handle with respect to an inner housing. The handle has a tab affixed to the inside wall of the handle. The inner housing has an angled slot in its wall adapted to receive the tab. When the blade is fully retracted, the tab rests on the shoulder at the top of the inner housing. A straight downward pressure on the handle causes the tab to engage the shoulder and will not allow the blade to extend. When the handle is rotated, the tab enters the slot and the blade is forced downward. As this occurs, the blade extends through a slot at the bottom of a blade cover. When the blade is removed from the object to be cut, the spring forces the handle to move with respect to the inner housing and causes the blade to retract within the blade cover.

The apparatus according to the present invention has avoidance of deformed or damaged shafts by construction where possible free maintenance of the balance of the pendulum being locked against the swings prevents production of applied unnatural force to the shaft. It includes a pendulum 60 having a laser beam source unit assembled thereinto, gimbals mechanism having the pendulum 60 hung therefrom, a stopper 70 having a function of stop of swings of the pendulum 60, and a pressure member 75 to press the pendulum against the stopper for stop of swings of the pendulum 60. The gimbals mechanism comprises a plurality of links 53, 55, 57, which are linked in series through combination of a plurality of horizontal shafts 52, 54 disposed in a parallel arrangement with each other and a plurality of horizontal shaft 56, 58, which is at the right angle to the horizontal shafts 52, 54.

  • Patent number: 6536123
    Abstract: A hybrid three-axis magnetic sensor for calculating the accurate direction of the earth magnetism. The hybrid three-axis magnetic sensor includes: a flux gate type magnetic sensor which is so formed that a base serves as a main member and detects two axis components of a magnetic vector defined by a plane parallel to the base; a Hall element which detects another component of the magnetic vector orthogonal to the base; a tilt sensor which detects a tilt angle of the base; and a CPU, wherein the flux gate type magnetic sensor and the Hall element are integrally structured together as a hybrid IC. The thus detected three dimensional magnetic vector is corrected in the light of inclination of the base, so that the direction of the earth magnetism is accurately calculated.

  • Patent number: 6536125
    Abstract: A device for generating angles has a ruler-shaped basic rail having a first guide extending in a longitudinal direction of the basic rail. A stop rail is arranged in the first guide of the basic rail and is rotatable and slidable into different positions relative to the basic rail and securable in the different positions. The stop rail has an underside provided with depressions positioned at an acute angle to one another and forming a star-shaped arrangement. The basic rail has a projection that engages the depressions.

  • Patent number: 6536127
    Abstract: A J-back calibration device is adapted to vary respective positions of the seat and the back on a chair to which it is removedly attached. A chair measurement device is mounted to the seat of the chair and is adapted to take measurements of the chair given a set position of the J-back calibration device. A design of experiments software is provided with test condition information including the variable positions of the J-back calibration device and measurements from the chair measurement device. The software generates a table of configuration settings for the J-back calibration device at which shirt-pull and bridging or other such variable sought to be optimized can be measured and provided to the software. Through graphical and other analytical tools, optimal configuration settings for the variable positions of the J-back calibration device are determined. The J-back of a chair is adapted to these calibrated settings.

  • Patent number: 6536130
    Abstract: An overlay mark for concurrently monitoring alignment accuracy, focus, leveling and astigmatism and a method of application thereof are disclosed. The overlay mark comprises four inner bars and four outer bars formed at the corners of exposure areas. The inner bar has a sawtooth area and a bar-shaped area, and the outer bar is a fore-layer etched pattern. Both the inner bars and the outer bars are formed into rectangles, and each bar is one side of a rectangle and none of the sides are connected. The sawtooth areas of the inner bars disposed on opposite sides are located at a same position. The rectangle formed by the outer bars encloses the rectangle formed by the inner bars. During the monitoring process, a testing beam scans across a scan area being divided into two areas, i.e., one being the outer bars and the sawtooth area of the inner bars, and the other one being the outer bars and the bar-shaped area of the inner bars.
