Abstract: A connector includes a base, a latch, and a first axle element. The latch is disposed on the base. The latch includes a main portion, a front-left arm, a front-right arm, a back-left arm, and a back-right arm, wherein each of the front end of the front-left arm and the front end of the front-right arm has a hook-shaped structure, and each of the back-left arm and the back-right arm has a hole. The first axle element is pivoted to the hole of the back-left arm and the base. The back-left arm of the latch is located along the lengthwise direction of the front-left arm, and the back-left arm and the front-left arm are connected by a connecting structure.

Abstract: The present disclosure is directed to techniques of zone-based target control in chemical mechanical polishing of wafers. Multiple zones are identified on a surface of a wafer. The CMP target is achieved on each zone in a sequence of CMP processes. Each CMP process in the sequence achieves the CMP target for only one zone, using a CMP process selective to other zones.

Abstract: Disclosed is an innovated structure for hand tools comprising a tool accommodation apparatus and a lighting equipment for supplementary lighting or an emergency lighting source. The tool accommodation apparatus further includes a took set installed therearound consisting several kinds of hand tool. The structure is characterized in that when the tools are to be used, a selected tool is pushed forwardly and upwardly from its fixed position to the top end of the tool accommodation apparatus ready for use.

Abstract: A CD container storage device includes an upper cover having a top and a vertical rear side wall and two vertical lateral side walls extending downwardly from three sides of the top, a lower cover having three upwardly extending side walls adapted to engage the three downwardly depending side walls of the upper cover to form a rectangular casing, and a disk holder dimensioned to be fitted into the rectangular casing, whereby a CD and its container can be separately fitted into the CD container storage device and a plurality of similar CD container storage devices can be conveniently connected together as desired.

Abstract: A hand tool includes a cylindrical casing which has a tapered front end, an annular groove around the tapered front end, and a plurality of tool bit grooves longitudinally extended from the tip of the tapered front end across the annular groove to the rear end of the casing, and a tool bit unit which includes a binding ring mounted in the annular groove of the casing, and a set of bits respectively pivoted to the binding ring and turned between a first position received in the tool bit grooves of the casing, and a second position retained in alignment with the casing longitudinally.

Abstract: A disposable cup dispensing device having an upper annular member and a bottom annular member connected together. A barrel is mounted on the upper annular member to hold a stack of disposable cups. A pivotable bottom cover is located at the bottom annular member. An endless cord is mounted in between the upper and the bottom annular member to hold a plurality of actuating plates located in radial grooves inside the upper and the bottom annular members. A link is connected between the bottom cover and one of the actuating plates. A spring with a curving upward tail is located on the inside of the bottom cover and pivoted therewith. When the bottom cover is opened, the link is lifted to twist the endless cord and to turn the actuating plates, thereby causing the plates to pull one of the disposable cup downwardly, permitting it to fall onto the curved tail of the spring member of the bottom cover.
