An electrical connector assembly is used to connect first and second flexible connecting strips of a film circuitry and a main circuit board. Each of the first and second flexible connecting strips has a flat end portion and a plurality of electrical terminals formed on one of the opposite side faces of the flat end portion. The electrical connector assembly includes an inverted U-shaped clip member and a connector board. The inverted U-shaped clip member has first and second leg portions. The first leg portion is integrally formed with the flat end portion of the first flexible connecting strip. The second leg portion is connected adhesively to the flat end portion of the second flexible connecting strip. The connector board has a plurality of conductive members formed on two opposed side faces of the connector board, and a mating portion for connecting electrically the conductive members to the main circuit board. The connector board is sandwiched bet ween the flat end portions of the first and second flexible connecting strips. The conductive members on the connector board are connected electrically and respectively to the electrical terminals on the flat end portions.

A computer key includes a one-piece base plate which is punched to form left and right retaining guideways that are spaced from each other in a longitudinal direction of the base plate. The retaining guideways include left and right retaining portions which extend uprightly from the base plate, and left and right blocking portions which extend from distal ends of the retaining portions away from each other and substantially longitudinal to the base plate. The blocking portions have left and right widths defined in a direction transverse to the longitudinal direction by front and rear left and right rough edges. A frame assembly includes first and second linking frames which are pivotally connected at intermediate portions thereof. Each of the first and second linking frames includes a transverse axle oriented in a transverse direction of the base plate, and has a middle segment of a length shorter than the width of the respective blocking portion and insertable sliably under the respective blocking portion, and front and rear segments which extend beyond the front and rear rough edges of the respective blocking portion. The front and rear segments of the transverse axles respectively have cut-out upper surfaces which do not contact the rough edges of the respective blocking portion.

A foldable data input device includes a keyboard, a hinge device and a lid. The keyboard is formed with a top face and opposing first and second side edges and has a plurality of keys mounted on the top face and a signal transmission device mounted on the keyboard. The lid is connected pivotally to the first side edge of the keyboard by the hinge device in order to cover the top face of the keyboard. The lid further has an inside face for confronting the top face, a touch pad and selection buttons provided on the inside face.

An automatic head retract system for a disk drive. The system operates in response to electric power turn off to retract the heads to a landing zone on the disk surface. The heads are retracted by operating a positioner motor under the control of logic internal to the disk drive unit without intervention by a host computer. The positioner motor comprises a multiphase DC brushless motor which, after power loss, is supplied with current from a capacitor charged during normal drive usage, and by the back EMF of a spindle motor. A latch mechanically locks the heads in the landing zone.
