An electroluminescence device having an excellent moisture-resistant property is disclosed. Such an electroluminescence device comprises a light emitting layer inserted between an opposite electrode and a transparent electrode to form a multi-layered structure, said structure being airtightly sealed by a pair of protective sheets and said ELD being able to be fitted to an external apparatus by means of a metal fixture. The ELD is characterized in that a metal composite film is formed by inserting a metal foil between a pair of resin films and is used for one of the protective sheets for said opposite electrode. The composite film having a notch which is formed by removing part of the metal foil around a portion of the metal composite film prepared to accommodate the metal fixture.

At least one of the movable electrode unit and the fixed electrode unit includes a plurality of electrodes, and capacitances between the one or more electrodes of the movable electrode unit and the one or more electrodes of the fixed electrode unit are detected.
摘要:
A driving signal is provided to six electrodes (driving electrodes) on one of the surfaces of each of three vibration legs of a three-pronged tuning-fork-type piezoelectric oscillator. Two output electrodes from among six electrodes (output electrodes) on the other surface thereof are connected to two current-to-voltage conversion devices, respectively. Since the two output electrodes are imaginarily short-circuited by the current-to-voltage conversion devices, there is no need to provide a ground electrode between the output electrodes. This makes it possible to simplify an electrode manufacturing process.
