  • Patent number: 6993989
    Abstract: A starting apparatus includes a drive motor and a reduction gear having a planetary gear for starting an engine by the drive motor via the reduction gear. An internal gear of the reduction gear includes a locking projection projecting in an axial direction. A rotation restricting member is formed with a guide groove in which the locking projection is loosely received and guided in a circumferential direction. A shock absorbing member is held in the guide groove in a state of being elastically in close contact with the locking projection in the circumferential direction. Thus, shock load to the internal gear is alleviated from the start.

  • Patent number: 6981430
    Abstract: A vehicular steering apparatus includes a column bracket secured to a steering column; and a fixing bracket secured to a vehicle body. The column bracket includes a top plate and a pair of side plates. The fixing bracket supports the column bracket via a support shaft. A support-shaft through hole formed in each of the side plates of the column bracket includes a slot extended along a longitudinal direction of the steering column. A resilient member is interposed between the top plate of the column bracket and a confronting portion of the support shaft. The resilient member biases the support shaft along a predetermined biasing direction to restrict play of the support shaft in the slot.

  • Patent number: 6976400
    Abstract: A method of damping a semiconductor wafer handling arm by attaching a spring and a mass coupled to the spring to form a mass spring system that is tuned to vibrate at a structural resonant frequency of the vibrating wafer handling arm. The spring has temperature insensitive spring characteristics and the mass and spring are constructed of materials that do not outgas or produce contaminants in a semiconductor processing environment. The mass spring system is preferably a cantilever beam spring connected to a high response point on the vibrating arm and oriented to vibrate in a plane perpendicular to the plane of the wafer. The mass is slidably adjustable along the length of the cantilever beam spring to adjust the resonant frequency. Vibration damping of the wafer handling arm is accomplished by the transfer of kinetic energy from the vibrating wafer handling arm to the mass spring system.

  • Patent number: 6973850
    Abstract: The transmission gear shift lever device has a variable select lever ratio adapted to accommodate most of the operating mechanisms of the conventional transmission gear shift (TGS) lever device without major design changes. The select lever ratio is a ratio of rotating angle of a select lever relative to the rotating angle of the TGS lever and can be varied during the select manipulation of the TGS lever, such that all shift stages in a 6-speed transmission can be controlled while the rotating angle of the TGS lever during the select manipulation is maintained at the same size as that of a conventional TGS lever device.

  • Patent number: 6966237
    Abstract: The first gear/reverse gate switch of the present invention includes a detent switch including a contact pin and a contact switch. When a manual transmission is shifted to a gear not in the first gear/reverse gate, the contact pin of the detent switch engages a recessed portion on a detent mechanism such that the contact pin does not engage the contact switch. This indicates that the transmission is not in a gear in the first gear/reverse gate. When the manual transmission is shifted to a gear in the first gear/reverse gate, the interlock moves the detent, pushing the contact pin into engagement with the contact switch. This indicates that the transmission is in a gear in the first gear/reverse gate. The spring forces the detent into a “relaxed position” when not in the first gear or the reverse gate, breaking switch contact.

  • Patent number: 6942394
    Abstract: A race for a bearing, which is mountable to a mount, has an annular bearing surface with a center axis defining an axis of rotation for the bearing and mutually perpendicular radial and transverse directions relative thereto. The race also has a radial wall that is adapted for mounting the race to the mount in a manner such that a bearing transfer load is transferred between the mount and the race in the transverse direction and the race bearing surface maintains its substantially annular shape independently of a load applied to the mount causing distortion of the mount when the race is mounted to the mount and the mount is loaded.

  • Patent number: 6935987
    Abstract: A wheeled vehicle incorporating a control methodology for regulating the power input and output of an inertial energy storage device, specifically a flywheel. The control methodology utilizes a continuously variable transmission (CVT) and comprises control of the CVT speed ratio based on feedback of the CVT output torque. The CVT ratio control signal is based on an error signal equal to the difference between operator input and CVT output torque. Operator input may be a positive or a negative value, a negative value corresponding to regenerative power. Operator input corresponds to required force or torque analogous to throttle opening or braking effort. This methodology continuously synchronizes the speeds of the inertial energy storage device and vehicle wheels, keeping frictional losses to a minimum.

  • Patent number: 6928895
    Abstract: A ballnut assembly is provided in which a locknut (20), which is normally unloaded becomes loaded in the event of failure of a primary load path. This loading causes relative motion between locking nut (24) and the threads of a shaft (8) such that on clearance there between is eliminated. This causes frictional forces to initiate a lock-up of the locknut.

  • Patent number: 6923084
    Abstract: A device for increasing a selection force is integrated into a support arrangement of a shift lever. The device is pivotable around a pivot axis and also around a tilt axis aligned transversely to the pivot axis. The selection force upon pivoting movements of the shift lever around the tilt axis is produced by at least one lever that is movable against a spring and a runoff roller placed in operative connection with the lever (24, 38). The device is integrated into a support arrangement for pivotable support of the shift lever by a casing in a housing. The support arrangement supports the shift lever pivotably with respect to the casing around the pivot axis and also supports the shift lever with the casing pivotably with respect to the housing around the tilt axis aligned transversely to the pivot axis.
