20140307988 | LINEAR GUIDE ASSEMBLY - A linear guide assembly has a bar device, multiple partitions, multiple containing spaces and multiple rolling balls. The partitions are mounted between two bars of the bar device at intervals to form the containing spaces. The rolling balls are respectively and rotatably mounted in the containing spaces. Each partition has multiple first protrusions and multiple second protrusions. Each rolling ball is in point-contact with the first protrusions and the second protrusions of adjacent two of the partitions. With the point-contact configuration, an outer surface of each rolling ball is lubricated by much oil. | 10-16-2014 |
20140097457 | SEMICONDUCTOR DEVICE - A semiconductor device includes a substrate and a semiconductor unit. The substrate includes a base and at least one pattern unit. The pattern unit includes a plurality of surrounding members disposed on the base and a central member surrounded by the surrounding members. A geometrical center is collectively defined by the surrounding members, an interval between the central member and the geometrical center is larger than zero. The semiconductor unit is disposed on the substrate and is operating with a current. | 04-10-2014 |
20120060631 | TWO-LIP DUST-PROOF WIPER OF A BALL SCREW - A two-lip dust-proof wiper of a ball screw having a main ring body, with a ringed sheet, and a screwed hole, a circumferential portion and first/second flanged portions. A wiping ring surface is set into the hole. Fine interference fit can be implemented between the wiping ring surface and the periphery of the ball screw. A first wiping lip is annularly formed onto the wiping ring surface for mating with the first flanged portion, and a second wiping lip is annularly formed onto the wiping ring surface for mating with the second flanged portion, such that the first/second wiping lips are protruded at both sides of the surface. The wiping lips and the periphery of ball screw are under interference fit, the interference being larger than that of the wiping ring surface and ball screw. The protruding direction of the wiping lips runs parallel with the flanged portions. | 03-15-2012 |
