摘要： An electrostatic discharge tolerant device includes a semiconductor body having a first conductivity type, and a pad. A surrounding well having a second conductivity type is laid out in a ring to surround an area for an electrostatic discharge circuit in the semiconductor body. The surrounding well is relatively deep, and in addition to defining the area for the electrostatic discharge circuit, provides the first terminal of a diode formed with the semiconductor body. Within the area surrounded by the surrounding well, a diode coupled to the pad and a transistor coupled to the voltage reference are connected in series and form a parasitic device in the semiconductor body.

摘要： A ball crew unit with dual ball deflect arrangements includes a pair of circulation ball deflect units. One of them is equipped axially in a first cavity provided in the nut, while the other is equipped radially in a second cavity provided in the nut. By so, the traditional buck toothed design for the external helical grooves of the shaft can be eliminated, and is unnecessary to lengthen the nut in order to avoid mutual interference between the ball deflect unit and the nut flange, the circulation tunnel formed in the nut does not have to run through the whole nut either so that the structure of the ball screw unit can be simplified. As a result the assembly work is facilitated, production cost is reduced while the mechanical property is upgraded.

摘要： A roller screw structure comprises a nut, a screw and a rolling assembly. The rolling assembly is movably disposed between the nut and the screw and includes at least one rolling cone. The slantwise rolling surface of the rolling cone contacts the spiral groove surfaces of the nut and the screw in a line-to-line manner, and the angle between the rolling surface and the self-rotation axis of the rolling cone is from 0 degree to 6.3 degrees. Thereby, making the distance between the self-rotation axis and the rolling surface of the rolling cone of the rolling assembly different can prevent the occurrence of speed difference caused at different rolling paths of the rolling assembly.

摘要： A communication device is disclosed, having a transceiving circuit, a timer circuit, and a control circuit. The transceiving circuit is used to transceive frequency hopping signals according to at least part of good channels in a channel map. The timer circuit is used to calculate a timespan of one or more communication intervals in which the transceiving circuit transceives the frequency hopping signals. The control circuit is used to compare the timespan with a time threshold to determine whether signal transmission tests with one or more bad channels in the channel map should be performed to update the channel map.
