    Abstract: A lead screw assembly having a lead screw rotatable within a hollow tubular portion of a reinforcing rail. A nut engages with threads of the lead screw and is movable along the reinforcing rail. The lead screw includes plurality of first threaded portions having an outer diameter and extending lengthwise of the lead screw; and at least one second gap portion having an outer diameter that is less than the outer diameter of the first threaded portions. The second gap portion is positioned between adjacent first threaded portions of the lead screw. At least one generally U-shaped bearing is secured within the reinforcing rail and contacts the lead screw at a second gap portion. Each U-shaped bearing supports the lead screw along its length as the screw rotates within the rail, so that the lead screw assembly can be safely operated at high speeds over comparatively long distances while minimizing whipping and vibration of the lead screw. The reinforcing rail can include a base portion which permits the assembly to be securely mounted to a support structure at any convenient location along its length. An anti-backlash nut assembly includes a threaded follower for engagement with the threads of a lead screw. A pair of wedges bias the follower in a radial direction so that the threads of the follower are brought into forcible engagement with the mating threads of the screw. In a preferred embodiment, the nut assembly is adjustable to provide variable levels of backlash resistance and wear-compensation.

    Abstract: A guide mechanism, which guides a slider along an inner wall surface of a frame, includes a plurality of resin sliding members retained by the slider. The plurality of resin sliding members include a pair of first resin sliding members that make sliding movement along first sliding grooves formed in a bottom wall section of the frame, a pair of second resin sliding members that make sliding movement along second sliding grooves formed in side wall sections of the frame, and a pair of third resin sliding members that make sliding movement along third sliding grooves formed in the side wall sections.

    Abstract: The invention relates to an actuator for actuating a moving member, said actuator essentially comprising a screw and at least two nuts engaged on the screw, relative movement between the screw and the nuts generating said actuation, said actuator further comprising a pin through which an electrical link passes, a force-transmitting element placed in the path of the force between the screw and the moving member via one of the nuts, and a mechanical extension of said force-transmitting element that extends to the vicinity of the other nut, the pin passing both through the mechanical extension and through an element coupled to the other nut so that any abnormal shift in the force-transmitting element relative to the screw results in shear between its mechanical extension and the element coupled to the other nut, causing the pin to break and causing the electrical link to be broken.
