摘要： A support pole for raising and lowering a supported object between a lower position and an elevated position is disclosed. The support pole includes an elongate pole and a carriage mounted for translational movement up and down the pole. Carriage locks at the top of the pole engage the carriage in the elevated position to prevent vibration of the supported object, and a stabilizer frame within the channel minimizes vibration during carriage transport. One or more electrical conductors are fixed in place, extending through at least a portion of the pole, terminating in an electrical contact for releasable engagement with a cooperating electrical contact mounted to the carriage as the carriage is raised into the elevated position.

摘要： A linear actuator comprises rotary motion producing means (1,2,3,4,5); linear motion producing means (6,7,10,11,12) coupled with the rotary motion producing means for converting rotary motion to linear motion; a driven member (18) movable linearly by the linear motion providing means from a first position to a second position; and backdrive means (22) for returning the driven member to the first position. The arrangement is such that the linear motion producing means includes torque reaction means (13,15,16,17) which, in normal operation, is in an activated condition and provides a torque reaction path to enable the driven member to be moved from the first to the second position but which, in the event of a fault, is in a de-activated condition so that it no longer provides the torque reaction path and the back-drive means can move the driven member to the first position, without disengaging the rotary motion producing means from the linear motion producing means.

摘要： An anti-backlash transmission mechanism that eliminates backlashes is disclosed. An actuator is connected to a transmitted element and a driven gear. The driven gear matches with a driving gear to be receive power transmitted from the driving gear. Through the actuator, the driving gear and the driven gear match tightly in the normal state to eliminate the backlash during positioning. During transmission, the pressure between the driving gear and the driven gear decreases, lowering the friction in between.

摘要： The present invention relates to a feed screw driving apparatus that moves a power transmission member, which engages a feed screw, in an axial direction of the feed screw by rotationally driving the feed screw using a driving source, such as an electric motor, and also to an information recording and/or reproducing apparatus that moves a pick-up apparatus with this feed screw driving apparatus and records and/or reproduces an information signal onto or from a disc-like recording medium In a feed screw driving apparatus that moves a power transmission member, which engages a feed screw, in an axial direction of the feed screw by rotationally driving the feed screw using a driving source, there is provided an elastic member that energizes the power transmission member in the axial direction of the feed screw. The gap between the feed nut and the feed screw is eliminated, so that the feed screw can be driven at high speed without driving errors (play) being produced and the driving of a slide member can be controlled with high precision.

摘要： An anti-backlash nut is assembled on a reinforced lead screw for bilateral motion lengthwise of the lead screw as the screw is rotated. A hollow, elongate reinforcing rail extends lengthwise of and surrounds the lead screw. A slot in the rail extends lengthwise of the central axis of the lead screw. The anti-backlash nut comprises two separate portions, each portion having a tongue which extends radially through the slot and has threads engageable with the threads of the lead screw for moving both nut portions in reciprocating motion lengthwise of the rail when the screw is rotated. Spring means are employed for forcing the nut portions apart to urge the flanges of their threads into forcible engagement with the threads of the lead screw to prevent backlash, while the anti-backlash nut translates laterally along the reinforcing rail.
