Abstract: A television receiver having a liquid crystal display device includes a receiver having a electromagnetically shielded case and a receiving circuit provided in the shielded case and electrically connected to an antenna for producing audio signals and video signals. A liquid crystal display panel of the liquid crystal display device is electromagnetically shielded by a transparent and conductive shielding film for shielding the liquid crystal display panel.

Abstract: 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.

Abstract: 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.

Abstract: An electronic timepiece having time indicating hands driven by a motor through a gear train, and having an analog-to-digital conversion system for time data comprising code disks rotated by the wheel train to provide hours and minutes information in digital coded form, together with means for converting this encoded digital information into digital signals representing hours and minutes information corresponding to the time information indicated by the hands and synchronized with the time indicated by the seconds hand of the timepiece.

Abstract: A movement structure for an electronic timepiece, in which a wheel train of a time indicating mechanism is supported between a wheel train bridge and a base plate. The base plate carries thereon a stepping motor connected to the time indicating mechanism, and the wheel train bridge carries thereon an integrated circuit chip.

Abstract: A method of assembling a semiconductor integrated circuit in which a semiconductor integrated circuit chip with bumps is bonded to a flexible film circuit substrate. The assembling method of the invention comprises a step of making the highest layer of the bump of solder or a low melting point metal treating the surface of the flexible film circuit substrate by gold-plating, and bonding the semiconductor integrated circuit chip and the flexible film circuit substrate with the former mounted face-down on the latter.

Abstract: An electronic timepiece including a battery, a drive motor, a drive, a display, and electronic circuits for driving said motor. The motor is a pulse motor and comprises a core, coil, yoke and rotor. The rotor includes a worm gear having worm teeth which engage with a gear wheel. The teeth on the worm gear are arranged and configured such that the initial and final portions of each tooth which engage with the gear wheel are parallel to the plane of rotation of the rotor thereby preventing torque applied to the gear wheel from being transmitted to the rotor.

Abstract: An extremely thin digital electronic timepiece comprising an electrooptical display element is disclosed. The timepiece essentially consists of a connector frame, supporting plate, flexible film-shaped circuit substrate and base plate. These constitutional members are manufactured in mass production scale by injection molding process, press working process etc. The circuit substrate is sandwiched between the supporting plate and the base plate. A portion of the connector frame is used to secure together the constitutional members into one integral body.

Abstract: An electronic timepiece is disclosed which has at least one display function in addition to an ordinary time display function and comprises a sole electro-mechanical transducer for dividing a kept time and driving a first display function and a second display function separately.

Abstract: An electronic circuit block for use in a timepiece comprising a circuit substrate with component-receiving portions, circuit components mounted on the component-receiving portions with terminals at the same level with the upper surfaces of the circuit components, an insulated layer made of polyimide resins formed on at least a part of the circuit substrate and in gaps between the components and the component-receiving portions and a conductive pattern formed on the insulated layer after a part of the insulated layer is excluded whereby connections of components are made by said conductive pattern.

Abstract: An electronic timepiece comprising a means for generating a base signal, an electromechanical transducer to convert the base signal into mechanical motion of a rotatable shaft, only a back side chain of wheels and a driving means whereby the back side chain of wheels is directly driven by the rotatable shaft. Furthermore, the driving means is coupled to the rotatable shaft such that idling rotation of the driving means occurs without rotation of the rotatable shaft when the timepiece is being set externally.

Abstract: An electronic timepiece with a digital display device employing electrochromic materials, such as titanate and niobate, as an electro-optical element. An electrochromic material produces different states of coloration depending upon the polarity of voltage applied thereto for a remarkably long period, and with a minimum of power consumption, whereby the timepiece enjoys a minimization in its size, a long life for its battery, and a variable design in the display.
