Abstract: A wiper is provided for use in a vehicle for wiping the windshield glass. A holder is fixed to a baseplate of the vehicle body and, against the holder, an inner bearing is supported so as to rotate about its axis. A pivot shaft is inclined relative to the axis of the inner bearing while being rotatably supported. The driving force is transmitted from a driving source into driving forces for a first driving apparatus for driving the pivot shaft and second driving apparatus for driving the inner bearing. Inversion apparatus or a rotating apparatus always rotates the second driving apparatus either in a direction opposite to or in the same direction as the rotational direction of the first driving apparatus.

Abstract: A control device for an automatic transmission is disclosed. The control device is provided with a base member mounted on a vehicle body. A shift lever is pivotably supported by the base member. The shift lever has a positioning pin movable in the axial direction of the shift lever. A guide member for guiding the shift lever is mounted on the base member, the guide member has a parking position part and a moving position part for engaging the positioning pin. The lock bushing for blocking disengagement of the positioning pin from the parking position part is mounted on the guide member and is supported by the guide member in a pivotable manner on a vertical pivoting locus surface. A lock solenoid for pivoting the lock bushing when releasing the shift-lock is mounted on the guide member. A lock releasing lever for manually pivoting the lock bushing to a shift-lock releasing position is mounted on the shift lever in a manner allowing movement parallel to the vertical pivoting locus surface.

Abstract: A gear arrangement includes two coaxial output bevel gears having a common pitch axis and rigidly coupled each to the other. Two coaxial bevel pinions, each of which meshes with a corresponding output bevel gear, are flexibly coupled together via a quill shaft. The quill shaft is used to adjust the preload of one of the pinions against the other, whereby the load capacity of the gear drive is substantially equal to the sum of the load capacity of the two pinion/gear pairs.

Abstract: A protective boot for preventing contamination of the oil in a hydraulic piston-cylinder assembly consists of an elongate flexible sleeve having a first end removably securable to the head of the cylinder and a second end removably securable to the distal end of the piston rod. The boot is split along a longitudinal seam which can be closed by a zipper, a hook and loop type fastening strip, or other suitable attachment devices. Several flexible metal or plastic stays encircle the sleeve at spaced locations to prevent the sleeve from contacting the piston rod. Each stay is split to accommodate the seam.

Abstract: A shifting mechanism for a multi-speed manual overdrive (OD) transmission. A "flipper" reverses the action of the shift stick for the final stage shift fork to maintain progressive "H" or "HH" shift patterns yet engage a direct drive coupling as the next-to-last range and OD as the final engagement. The mechanism employs a quadrangular frame slidably received on two adjacent shift rails in a shift rail array. The frame has one side above the shift rail array notched to engage the shift stick end of an opposite side below the array. The flipper is pivotally mounted below the array with one end engaging a notch in the frame and the other end engaging the final stage shift fork so as to minimize bending stresses on the fork end and reaction loads of the sliding frame on the shift rails.

Abstract: An actuator suitable for use with a valve has a design allowing for easy control or adjustment of the force applied to the valve. The actuator motor has a cam which operates a follower surface of a spring-loaded arm mounted for rotation on a carriage. The carriage is mounted for linear motion and connected to the control element of the valve. The actuation force can be controlled or adjusted by changing the relative positions of the arm's center of rotation, the point on the arm at which the spring applies force, and the position of the cam. In a preferred embodiment, the position of the arm's center of rotation is changed by moving a pin from one set of holes in the carriage and the arm to a second set of holes in the carriage and the arm.

Abstract: A motion converting mechanism wherein two sets of one-way clutch mechanisms are added to a mechanism for converting a rectilinear reciprocating motion into a rotary motion through a rack and pinion combination. The two sets of one-way clutch mechanisms include one that engages during the forward movement of the rack and the other that engages during the reverse movement of the rack, both of which rotate an output shaft in the same direction when they engage. With this arrangement, the motion converting mechanism according to the present invention can rotate the output shaft in the same direction during both forward and reverse movements of the rack, thereby improving efficiency in converting the reciprocating motion into the rotary motion as compared with the conventional one. Thus, various rotary tools utilizing this motion converting mechanism can be provided.

Abstract: An adjustable timing gear arrangement having an output shaft and a camshaft operable in timed relationship with the output shaft comprises a first rotatable drive member driven by the output shaft with a second rotatable drive member mounted on the camshaft and operably connected with the first drive member for rotation in timed relation therewith. The second drive member is mounted on the camshaft for rotation on a common axis with the second drive member and the camshaft and is secured thereto to fix the angular relationship of the members. The mounting permits limited relative angular rotation of the members when the members are not so secured. For adjusting the relative angular positions of the second drive member and the camshaft there is an assembly including an unthreaded, cylindrical stud extending from the camshaft into a radially extending slotted opening through the second drive member. The opening includes angularly spaced, parallel sides.
