IPC: H01L29/47
Filed: 1988-08-17
Abstract: PURPOSE: To obtain a higher reliability device having a high operation characteristic by covering a conformal Si oxide layer on a wafer and anisotropically etching to form a sidewall oxide protection layer. CONSTITUTION: A composite diode 44 is formed by patterning a thick silicon oxide layer 18 to determine the position of the diode.

Filed: 1989-08-08
Abstract: PURPOSE:To facilitate focusing by using an accessory with a close-up photographing function and setting the switching circuit of a camera main body on a spot area side in response to a generated signal. CONSTITUTION:An IC card which is mounted on an IC card CD camera main body as an accessory has a means which changes a distance measurement area forcible into the spot area in close-up photographic mode.

Title: Acceleration sensor and its measuring method
Inventor: UEDA TAKAYUKI
IPC: G01P15/18
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a capacitance type acceleration sensor capable of having an excellent bare characteristic, and having vibrator construction which does not fundamentally receive the viscous resistance of air. SOLUTION: For this acceleration sensor, constitution of interposing an elastic body between a fixed board and a flexible board which practically form a capacitor, as a means for making a vibrator immovable outwardly so as not to receive the viscous resistance of air, and of setting required reaction force by the elastic body is adopted. Control is so performed that the board may not vibrate, by applying base volt to cancel the reaction force of the elastic body and attracting the vibrator (flexible board). When external force acts on the board, and tries to displace it either to an attraction side or repulsion side, force which is opposed to this external force is caused to act.  If the base voltage is increased or decreased so that the board may not be displaced, the difference between the base voltage and voltage required for driving can be judged to correspond to the external force having acted, and an input is detected without vibrating the board.

Title: Photosensitive polyamic alkyl ester composition and using method thereof
Inventor: JIEFURII UIRIAMU RABADEII
IPC: G03F7/038
Filed: 1992-08-03
Abstract: PURPOSE: To form a polylmide image on a substrate by incorporating a polyamic alkyl ester compsn. into a photosensitive negative or positive gradation compsn. CONSTITUTION: When a photosensitive negative gradation compsn. containing a polyamic alkylester and photosensitive base-producing agent is exposed, the photosensitive base-producing agent in the exposed area produces radical base. This acts as a catalyst to imidize the polyamic alkylester into insoluble partially imidized polyimide. When a photosensitive positive gradation compsn. containing polyamlc alkylester base or base precursor and a photosensitive acid-producing agent is exposed, the photosensitive acid producing agent in the positive gradation compsn. produces acid, which traps base in the exposed area of the film. By successively heating the positive gradation compsn. at low temp., partial imidization in the nonexposed area of the film is caused by the base catalyst. The positive gradation compsn. is developed by using a proper solvent.
