    摘要： A controlling device of a tunable filter includes a base, a tunable filter on the base along an optical path between first and second optical fibers, a holder rotatably installed on the base to support the tunable filter, a driving unit installed on the base for providing a rotational force, a speed reducing device, and a rotating unit for rotating the holder in accordance with the linear movement of the movable member. The speed reducing device has a worm gear extending from a rotating shaft of the driving unit, and a movable member provided with a threaded hole engaged with the worm gear to allow reciprocal movement along the worm gear according to the rotation direction of the worm gear.

    摘要： The orientation of a vehicle rear-view mirror carried by a mirror support member is adjusted from inside a vehicle about a horizontal axis by turning a tubular bearing member, to which the mirror support member is hinged, about its axis by rotating a first control member through a reduction drive and, independently, about a generally vertical axis defined by the axis of the hinge by moving a push member axially in the passage in the tubular bearing member by rotating a second control member.

    摘要： A mechanical actuator for valves and other mechanical devices, according to the present invention, includes a locking mechanism disposed about a rotatable valve-actuating stem that normally maintains the actuator in a locked condition, thereby preventing inadvertent movement of the valve or other mechanical device with which the actuator may be associated. The locking mechanism is unlocked upon predetermined initial rotation of a handwheel or other means for rotating the actuating stem of the mechanical actuator, thereby allowing the actuator to open or close the valve mechanism. Cessation of rotation of the handwheel or overrunning of the actuator that might occur by pressure actuation of the valve will cause automatic relocking of the actuator.
