Abstract: A memory module assembly includes a printed circuit board (10) having a heat-generating electronic component (14) thereon, and first and second heat-dissipation plates (20), (30) attached on opposite sides of the printed circuit board. The first heat-dissipation plate includes a first hook (24) extending from a side thereof and the first hook includes a resisting portion (242) extending from an end of the first heat-dissipation plate and a first engaging portion (244) extending from a free end of the resisting portion for resisting the printed circuit board and the second heat-dissipation plate. The second heat-dissipation plate defines a depressed portion (34) in a side thereof for engaging with the first hook. The other sides of the first and second heat-dissipation plates engage with each other to clamp the printed circuit board between the first and second heat-dissipation plates.

Abstract: A hard disk drawing device includes: a latch housing having a front wall that is formed with a pair of guiding holes; a pair of fastening plates extending rearwardly from the latch housing in a longitudinal direction and adapted to hold a hard disk therebetween; a pair of latches mounted movably in the latch housing and movable along an axis perpendicular to the longitudinal direction between locked and unlocked positions; an urging member disposed between and abutting against the latches for urging the latches toward the locked position; and a pair of operating levers protruding frontwardly from the latches in the longitudinal direction through the guiding holes in the front wall of the latch housing for moving the latches toward each other from the locked position to the unlocked position.

Abstract: A air shroud installed on a circuit board is composed of a circuit board which is installed with an outer housing, an inner surface of which is connected with at least more than one fan, and a side of which is provided with an air exit. The fan is provided with an air entrance and an air exit, wherein the air exit is corresponding to the air exit of outer housing. Air sucked in by the air entrance of fan is expelled out of the air exit of outer housing to be exported, through the air exit of fan, such that the air can be led to another space area or be used to dissipate heat from a specific electronic component.

Abstract: A flat display module including a display unit; a protective cover fastened to the top side of the display unit by screws, having a plurality of retaining notches and a plurality of retainer rods at two opposite sides; a display holder frame for holding the display unit and the protective cover on the inside, the display holder frame having a rectangular center opening, which receives the display unit and the protective cover, a plurality of hooks and retaining holes respectively fastened to the retaining notches and retainer rods of the protective cover, a plurality of outward half-round lugs at one side, and a wire hole adjacent to one half-round lug; a stiff backing fastened to the bottom side of the display holder frame by screws, having a plurality of outward half-round lugs respectively matched with the outward half-round lugs of the display holder frame for connection to a computer mainframe by pivots; and a lead wire inserted through the wire hole on the display holder frame, having a first electrical
