An objective lens drive/support mechanism in an optical disc player system includes an objective lens support member which is slidably and rotatably secured to a main shaft of the mechanism. An objective lens is supported by the objective lens support member at a position which is separated from the main shaft by a predetermined distance. The objective lens support member is driven to slide along the main shaft to perform the focus control, and the objective lens support member is rotated around the main shaft to perform the tracking operation. A symmetrically £37 8 + 38 + 0 shaped elastic damping member is tightly secured to the main shaft at the center of the symmetrically + 37 8 + 38 + 0 shaped elastic damping member. Both ends of the symmetrically + 37 8 + 38 + 0 shaped elastic damping member are fixed to the objective lens support member, whereby the single symmetrically +37 8+38 + 0 shaped elastic damping member conducts the damping operation in both the focal direction and the tracking direction. + RE
4687156 LOCK MECHANISM FOR WEBBING RETRACTOR
4687314 SHUTTER RELEASE MECHANISM FOR AUTOMATIC CAMERAS Klaus Raschke assigned to W Haking Enterprises Limited A delayed shutter actuation system for cameras providing from pre-flash or ambient light sensings automatic focusing control, automatic aperture control, or both, features a springenergized shutter slide member coupled to a velocity limiter over an initial portion of the release stroke. A spring-driven focus control member, or a spring-driven exposure control member, or both, are coupled through movable regulator members to the shutter slide through lost motion couplings so that their respective movement rates are governed by the velocity limiter until they are locked in proper position by electrically controlled locks controlled responsively to such sensings. During a terminal portion of the motion of the shutter slide the velocity limiter automatically disengages to allow an unimpeded motion of the slide to actuate the shutter. In the preferred form of the invention exposure control is secured by using a variableaperture impulse shutter and a stroke-control cam positioned as a rebound limiter and rotatingly oriented responsively to motion of the exposure control member.
Shinji Mori, Aichi, Japan assigned to Kabushiki Kaisha Tokai-Rika-Denki-Seisakusho A lock mechanism for a webbing retractor employed in a seatbelt system for a vehicle designed to protect an occupant in an emergency situation of the vehicle. A ratchet wheel is provided coaxially with a lock ring adapted for stopping, when an emergency situation of the vehicle occurs, the rotation of a webbing take-up shaft in a direction in which the webbing is unwound. A lever which is activated by the action of an acceleration sensor is engageable with both the ratchet wheel and the lock ring. The rotation of the take-up shaft is transmitted to the ratchet wheel through friction. When the vehicle is in a normal state, the ratchet wheel is rotatable together with the take-up shaft and gives no resistance to the rotation of the take-up shaft. When the webbing is wound up in a state wherein the lever is engaged with the lock ring, the ratchet wheel pushes out the lever so as to disengage from the lock ring. Accordingly, it is possible to prevent the webbing from being undesirably wound up and tightened when the vehicle is running on a rough road.

The steering column has upper and lower sections, pivotable with respect to one another about a first lateral axis. A first pawl and cylinder, mounted respectively to the upper and lower sections, rigidly connect these sections when engaged, but permit these sections to pivot relative to each other when the pawl is retracted from the cylinder.
