Filed: 1987-05-28
Abstract: PURPOSE:To detect a displacement quantity with a light signal and to detect small acceleration with high accuracy by providing a means which displaces a base member relatively according to acceleration applied to the base member and a photodetecting means which photodetects light from a light projecting means, and connecting one-terminal sides of the projecting and photodetecting means to a displaying means and the other-terminal sides to the base member. CONSTITUTION:When acceleration is applied to an acceleration detecting device, a force proportional to the value of the acceleration is generated at a weight 4 and the whole of a cantilever beam 1 is stressed. The cantilever beam 1 is displaced by the stress. Then a point irradiated with light from one terminal of an optical fiber 4 moves on the photodetection surface of a detection element 6 according to the displacement of the beam 1. Phototransistors as thin film semiconductors form a 256X256 plane matrix on the photodetection surface of a detecting element 6. Then the detecting element 6 converts the point irradiated from one end of the optical fiber 4 into a binary code of 8X8-bit code which is outputted. Namely, the detecting element 6 outputs the acceleration and direction as binary codes.

Filed: 1990-05-23
Abstract: PURPOSE:To eliminate a welding condition such as a requirement for a stop location on an electrode supporter by directly press-actuating an electrode supporter providing an electrode which allows the current to flow under pressure, with an output shaft. CONSTITUTION:Indentation of intercell junction members 2, 2' at a projection 17 of an electrode is performed. Good connection can be obtained with a further indentation while connecting the intercell junction members, since a plane 18 of the electrode impinges against the intercell junction members 2, 2' with the result that an indentation force with a protrusion 17 decreases. Traces caused by the impingement with the electrodes 3, 3' remains at the intercell junction members 2, 2', since a force applied on the electrodes 3, 3' with a cylinder is approximately one ton and movements of electrodes 4, 4' are stopped by impinging electrodes 3, 3' against the intercell junction members 2, 2'.

Abstract: PURPOSE:To improve uniformity of film thickness and provide a semiconductor device provided with an insulating film which allows high throughput by a small number of processes by simultaneously promoting oxidation and nitriding to an Si substrate so as to form the oxide nitride film as an insulating film by lamp annealing. CONSTITUTION:An oxide nitride film as an insulating film is formed on an Si substrate by one-step process by lamp annealing by simultaneously promoting oxidation and nitriding to the Si substrate.
