Abstract: A computer enclosure includes a chassis (60) and a hood (10) attached to the chassis. The chassis includes a rear panel (90) defining a slot (91) and a pair of side flanges (71). Each side flange defines a number of cutouts (74) and a number of slits (75) exposed to the cutouts, respectively. The hood has a pair of side walls (30) and a J-shaped catch (40) extending from a rear flange (32) between the side walls. The catch of the hood is received in the slot of the chassis, allowing the hood to be rotatable with respect to the chassis between an open position and a closed position while being selectively removable from the chassis when at the open position. The J-shaped catch engages with the slot for supporting the hood at the open position. Each side wall has a number of latches (31) for being received in the cutouts and moved into the slits of the chassis thereby securely fixing the hood to the chassis when the hood is at the closed position.

Abstract: A flexible wiring board that can bridge wires and also can prevent production of conductive foreign materials in use, to secure good performance of a magnetic head. The flexible wiring board for connecting therethrough a suspension substrate having mounted thereon a magnetic head of a hard disk drive and a control circuit substrate for actuating the magnetic head includes a short-circuit forming portion for forming a shorting portion for bridging wires to prevent electrostatic destruction of the magnetic head; and a cut for removing the shorting portion. When the flexible wiring board is cut along the cut, the shorting portion can be removed without producing conductive foreign material resulting from the cutting off of the shorting portion.

Abstract: A radio having a detachable pod assembly and a pair of silicone keypads. The first silicone keypad is located within the detachable pod assembly, while the second silicone keypad is closely coupled with a printed circuit board that is electrically coupled with a microprocessor based controller. When the pod assembly is snapped into the radio faceplate, there is preferably a 0.2 mm interference fit between the two silicone keypads. When the user depresses the first silicone keypad, the actuation forces depress the second silicone keypad in series. As the second silicone keypad is depressed, a carbon contact “pill” on the second silicone keypad contacts the printed circuit board and signals the circuit board's microprocessor that a button has been depressed. The microprocessor then directs the radio to respond accordingly.

Abstract: A housing for an electrical device including opposed supports or ribs receiving thereon a circuit board having first and second sides separated by a width “a”. A first board support is attached to the housing and has a first side surface, a first support surface substantially perpendicular to the first side surface for supporting the circuit board, and a first recess in the first support surface. A second board support is attached to an opposing side surface of the housing. The side surfaces of the board supports are separated by a distance “b”. When distance “a” is greater than distance “b”, the circuit board is retained in an interference fit. Scrapings that are formed during the insertion of the circuit board into the housing can be collected in the support recesses, which provide relief areas, to avoid interfering with the proper seating of the circuit board on the board supports.
