Abstract: 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.

Abstract: A self-lubricating ball screw comprises a nut, a screw shaft, at least one lubricating unit and at least one external oil tank. The lubricating unit is disposed in the nut, an end of the lubricating unit protrudes out of the nut and contacts the screw shaft, and another end of the lubricating unit is connected to the oil tank for absorbing the lubricating oil to the lubricating unit from the oil tank. An opening is formed in a side of the respective oil tanks, allowing for radial movement of the screw shaft. With the opening, the oil tank can be replaced at any time. The lubricating unit straddles the wipers and transmits lubricating oil to the protrusion without affecting the original arrangement of the wiper at either end of the nut, thus effectively saving the space of the oil tank, simplifying the structure and improving the maintenance efficiency.

Abstract: 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.

Abstract: A circulation passage structure for a ball screw, the circulation passage structure is used to connect the helical groove and the circulation hole of the nut, so as to form a circulation path for a plurality of balls and spacers. Due to the spacers move in a manner of being clamped between two balls, the spacer inside the return path will be pushed to move inward. The degree of curvature of the inner guiding surface connected to the inner curve can be moderated by shifting outward the location of the center of the inner curve and increasing its radius of curvature. By such arrangement, the spacer will not contact the inner guiding surface when it is pushed to move inward, and the spacer can pass through the return passage easily without the problem of impacting the return passage.
