Abstract: A cable guide assembly is used in a winch device having a rotatable cable shaft and a cable wound on the cable shaft. The cable guide assembly includes a support unit, a holding unit, and a coupling unit. The support unit includes a support member formed with a cable hole for extension of the cable therethrough, and two roller rods disposed rotatably within the support member and disposed at opposite sides of the cable. Each roller rod has a portion exposed from the cable hole of the support member. The holding unit is disposed at a side of the support unit opposite to the cable shaft and is used for stretching taut a portion of the cable between the cable shaft and the holding unit. The coupling unit interconnects the holding unit and the support member.

Abstract: A clamp affixes a wafer by entirely covering the edge of the wafer, wherein the radius of the inner surface of the clamp is about 1 mm shorter than the radius of the wafer. Besides, there are four pairs of square protuberances distributed even along the inner surface of the clamp for affixing the wafer, wherein the square protuberances only hold the edge of the device regions of the wafer. Even though the wafer is slightly off position, the square protuberances are still able to affix the wafer properly. In addition, the lifetime of the clamp of the invention is about 100 hours, which is two times of a conventional clamp, so that the cost is reduced.
