A television receiver employs a liquid crystal display panel mounted in a unit which can be set into either a closed position in which the display panel is disposed within a recessed portion of the case of the television set, and an opened position in which ambient light passes through the display panel to be reflected from a mirror towards the viewer. In conjunction with this arrangement, operating control members are positioned to facilitate one-hand operation of the receiver, and the largest circuit components and batteries are positioned with respect to the display panel and control members such as to minimize the overall size of the receiver.

Liquid crystal display television receiver

A liquid crystal television receiver has a first housing containing a television receiving circuit, a mirror mounted on an upper portion thereof, and a battery for driving the television receiving circuit, a second housing containing a liquid crystal display panel, and a third housing containing a light emitting element. The first, second and third housings are pivotally connected with each other at rear portions thereof, respectively.

An electro-optical display timepiece provided with a display changeover switch circuit manually controlled by a single external push button so that various displays including an alarm function display, chronograph function display and timer function display as well as time display may be obtained in accordance with the length of a time period, for which the push button is being continuously depressed.

Electro-optical display timepiece

A watch body for an electronic watch containing an integrated circuit chip and a printed circuit board is disclosed. The watch body comprises an upper case and a bottom cover which are selectively interconnected one with the other. A lead package frame is sandwiched between the upper case and the bottom cover and contains a plurality of electrical leads disposed thereon and electrically coupled to the integrated circuit chip. The lead frame has first and second sides with the first side having a first cavity with the integrated circuit chip matingly engaged therein. The plurality of leads are disposed on the first side of the lead frame so as to surround this first cavity down the circuit chip. The second side of the lead frame has a second cavity with the printed circuit board disposed therein. By the use of the watch body of the instant invention, a significantly smaller number of components, a simpler manufacturing process is achieved.

Electronic timepiece substratum

A liquid crystal display electronic watch comprises a metal substrate, whose upside and downside surfaces are insulated by a flexible print sheet. A liquid crystal cell and a time keeping decoder drive circuit are arranged on the upside of the substrate and other circuit elements are arranged beneath the downside thereof. The exteriorly operating parts are arranged around the periphery of the substrate. All of the electrical and mechanical operating members are arranged in a plane with respect to the substrate and so electrically connected and mechanically interlocked that date and/or week day are displayed with the least possible members. The watch is thin, small, simple in construction and reliable in operation.

An integrated circuit package structure wherein electrodes of an integrated circiut chip are directly bonded to metal lead members within the package. A portion of the substrate is enclosed inside the package to support the package. Holes are provided on the substrate for positioning and securing the package to the substrate. The substrate has a generally rectangular opening disposed therethrough arranged and configured to receive an integrated circuit chip and at least two additional openings disposed in said substrate so as to form at least two support arms adjacent to the rectangular opening. The integrated circuit package has a top member, a bottom member and a circuit chip. The circuit chip has a plurality of electrodes disposed thereon in a predetermined configuration for selectively coupling the lead members which are disposed on the substrate. By the use of the integrated circuit package structure of the present invention, circuit packages may be securely and easily coupled to a substrate and held in position.

Structure for packaging integrated circuits

A switch mechanism for an electronic timepiece which makes use of an electro-optical display element. The switch mechanism serves to effect erasure, correction and the like of the display and comprises an exteriorly operated member provided in its axial direction with a plurality of stable positions and rotatable about its axis at the stable positions and provided in its rotating sense with stable positions. An erasing switch is provided for erasing the display at the stable positions when the exteriorly operated member is rotated at one of the stable positions in its axial direction. A correction switch corrects the display at the stable position when said exteriorly operated member is rotated at at least one other stable position in its axial direction.
