摘要： An electrostatic discharge protection device for protecting an inner circuit, which is operated in a source voltage, is provided and includes a protection unit and a control unit. The protection unit provides a discharge path for transmitting an electrostatic signal from a pad to a ground line. According to a voltage level at a control end, the protection unit adjusts a holding voltage and a triggering voltage determining whether to conduct the discharge path. When the source voltage is supplied, the control unit transmits the input voltage to the control end of the protection unit, so as to raise the holding and the triggering voltages of the discharge path. When the source voltage is not supplied, the control unit switches the control end of the protection unit to a floating condition by the electrostatic signal, so as to lower the holding and the triggering voltages of the discharge path.

摘要： A preload structure for a ball screw in the inner surface of a nut is formed a helical groove whose lead is different from the lead of the adjacent helical groove to produce a lead deviation between the helical groove of the nut and the helical groove of the screw. By such arrangements, the lead deviation can be used to achieve the preload objective, thus reducing the fitting number demanded of the circulation system. Consequently, not only the single circulation system fittings can be used, but also the length of the nut is shorter and without extra machining, and the producer only needs to control the deviation of the interval helical track during rubbing to achieve various preload changes.

摘要： A spacer contains a magnetic filler and is disposed between the magnetic conductive balls. The magnetic filler produces an indirect magnetic attractive force on the balls, therefore, when the interval between the two neighboring balls is overlarge, the spacer will not tip over under the effect of gravity or centrifugal force, but will be adsorbed on the balls by the magnetic filler.

摘要： A spacer structure for cross rollers comprises a frame and four protruding wings, the protruding wings are arranged in pairs on opposing sides of the frame and outwardly extend therefrom. The two inactive end surfaces of the roller are confined between the paired protruding wings of the spacer. The slenderness ratio of the roller is designed to be 0.7-0.98 for facilitating installation of the roller between the paired protruding wings of the spacer, and such arrangement can effectively reduce the contact area between the spacer and the roller. The paired opposite protruding wings can provide a stable positioning effect to the end surfaces of the roller.

摘要： An internal circulation ball screw includes a threaded shaft, a nut having a receiving space, a circulation member mounted to the receiving space and having a first circulation groove and a second circulation groove, and a plurality of rolling members running between the threaded shaft and the nut. The first circulation groove defines a first front section, a first rear section, and a first curved section communicating with the first front section and the first rear section separately. The second circulation groove defines a second front section, a second rear section, and a second curved section communicating with the second front section and the second rear section separately. The first and second curved sections define a predetermined included angle with respect to the threaded shaft radially. Therefore, the wall between the circulation channels is uniform to enhance the durability of the ball screw.
