    摘要: A semiconductor device comprising a metallic leadframe (103) with a first surface (103a) and a second surface (103b). The leadframe includes a chip pad (104) and a plurality of segments (107); the chip pad is held by a plurality of straps (105), wherein each strap has a groove (106). A chip (101) is mounted on the chip pad and electrically connected to the segments. A heat spreader (110) is disposed on the first surface of the leadframe; the heat spreader has its central portion (110a) spaced above the chip connections (108), and also has positioning members (110b) extending outwardly from the edges of the central portion so that they rest in the grooves of the straps. Encapsulation material surrounds the chip, the electrical connections, and the spreader positioning members, and fills the space between the spreader and the chip, while leaving the second leadframe surface and the central spreader portion exposed.

    摘要: An improved adjustable box wrench having a mouth (9) with a plurality of gripping surfaces (27, 31, 32) for surrounding a nut, bolt or the like. A movable jaw (5) allows the size of the mouth to be altered when a worm screw (8) is turned. The worm screw (8) has gear (24) which fit between teeth (20) in an arm (4) extending from the movable jaw (5). The adjustment arm (4) and worm screw (8) fit into cavities (14, 17) in the wrench body (1). Increased lateral support for the movable jaw is provided by protrusions (19) on each side (21) of the jaw which fit into and move longitudinally within channels (26) in fixed gripping surfaces (32) on opposite sides of the mouth (9). A removable closure plate (6) covers the adjustment arm (4) and the worm screw (8) and facilitates assembly of the wrench and disassembly for repair or other purposes.
