Interconnection is removably provided between a liquid crystal panel and a circuit board or semiconductor chip which provides exchangeability for the liquid crystal panel which is advantageous because of the limited operating life inherent in liquid crystal composites. Contact areas of the circuit chip confront contact areas (or electrode areas) of the liquid crystal panel with interposition of compressible and resilient connector means which complete the circuit therebetween. In one of the pref...

In a flexure crystal, flexural vibration will occur when a unidirectional electric field is applied thereto in a manner that strength of the electric field varies from point to point. For the fork type of crystal vibrator, each of branches is provided with electrodes at the top wall, the bottom wall and the outer side wall for application of the strength-variable unidirectional electric field.

A ceramic package includes a ceramic case for installing a piezo-vibrator therein. Capacitors are formed directly on the bottom surface of the ceramic case through the multi-layer printing method. Electrodes of the capacitors also function as input and output electrodes for the piezo-vibrator.

Compressible interconnection is removably provided between a liquid crystal panel and a circuit board or a semiconductor chip to provide exchangeability for the liquid crystal panel from the viewpoint of the limited operating life inherent in liquid crystal composites. A desired number of electrodes for electrical connection are provided on both the liquid crystal panel and the circuit board to confront each other. The compressible interconnection means comprises a stack including a multiplicity...

A method for manufacturing a plane antenna that coats dielectric with conductor and forms a pattern free of the conductor on a surface of the dielectric which is otherwise coated with conductor includes the step of molding the dielectric and the pattern through injection molding using a mold that has the pattern.

A driving circuit of a liquid crystal display device including a first insulating substrate on which a plurality of signal lines and a plurality of scan lines are disposed, and pixel transistors made of thin film transistors are disposed in matrix at intersection points of those lines; a second insulating substrate opposite to the first insulating substrate; and a liquid crystal held between the first and second insulating substrates, in which the driving circuit is disposed on the first insulat...

A semiconductor device includes a first conductive layer; an interlayer insulative layer having an opening; and a second conductive layer. The first conductive layer, the interlayer insulative layer and the second conductive layer are sequentially laminated. The opening is partially covered by the second conductive layer, and an area of the first conductive layer is substantially entirely covered by the second conductive layer in the opening.
