IPC: H01G4/12
Filed: 1987-12-25
Abstract: PURPOSE:To improve the DC bias characteristics of a grain boundary insulating type semiconductor ceramic capacitor whose main component is strontium titanate, by dispersing a specified amount of glass frit and bismuth sesquioxide into organic vehicle. CONSTITUTION:After valence control element composed of yttrium is added to strontium titanate, and granuation and grading are performed, the added material is crashed and mixed. Then the material is dehydrated, and dried. After vinyl acetate as binder is added, and granuation and grading are performed, the material is formed into a circular plate, and calcinated in the air. Then firing is performed at 1400 deg.C in a reducing atmosphere for two hours. After paste composed of copper oxide, bismuth oxide and lead oxide is spread on the circular plate, and dried, the paste is baked at 900-1300 deg.C in the air for about one hour. Electrode paste is made as follows; 100 parts by weight of silver powder, 0.01-5 parts by weight of glass frit, and 0.01-5 parts by weight of bismuth sesquioxide are dispersed and suspended in organic vehicle. This electrode paste is spread on both main surfaces of a ceramic unit by screen printing method. This paste is baked by heating at 800 deg.C for 20 min, thereby forming electrodes.

Title: Image processor, method of processing image, and storage medium readable by computer
Inventor: SHIBAMIYA YOSHIKAZU
IPC: G09G3/20
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To adjust with precision a phase of a sampling clock used for an A/D conversion of an image signal. SOLUTION: An ideal waveform Vt of an image signal along dot clock Cs is distorted like a waveform Vp during transmission. Moreover, A sampling clock Cr1 generated from a horizontal synchronous signal contains jitters Δt, and if VP of such a waveform is processed by A/D conversion, variations of ΔV1 occur. Therefore, if the waveform VP is decreased in offset and increased in gain, a maximum variation part of Vp is processed by A/D conversion to be developed as B of the point Z of the waveform Vc1. It is possible to reduce the variations as ΔV2 by averaging the first and last large variation parts like the point Z in one line, obtaining Cr2 by phase-adjusting the above Cr1 according to the average value, and using it as a sampling clock.

Abstract: PURPOSE:To output storage information in the form of a light and to control the emitting direction by means of a signal from an external part by composing at least one area of an anode area or a cathode area of plural areas to be electrically insulated mutually in an element. CONSTITUTION:An anode area 44 forms a semiconductor layer area between anode electrodes 181 and 182 and an n-GaAs 15 made into an n-type gate layer, and a cathode area 45 forms a semiconductor area between a cathode electrode 19 and a p-GaAs 14 made into a p-type gate layer. A groove 20 for separating an element separates the anode area 44 in dividing it into plural number of areas, on the other hand, the gate areas are made common, and thereby, the whole element can be made from an OFF-condition into an ON-condition regardless of which the positions of the gate areas a trigger light is made incident on. When a voltage is impressed to one point of the anode area 44 divided into plural areas after the ON-condition is in, a light emission is intensively generated in such an area. The storage information is outputted in the form of the light by using such a phenomenon, and the emitting direction is controlled by the signal from the external part.

Title: Bead core for absorbing noise
Inventor: TSUTSUMI HIRONOBU
IPC: H01F17/06
Filed: 1992-12-14
Abstract: PURPOSE:To improve the pitch-length accuracy and noise absorbing ability of bead cores by providing a recessed section halfway between two holes each in each bead core. CONSTITUTION:A lead frame 6 is folded in a U-shape and passed through one hole 2 after the frame 6 is passed through another hole 2. When signals on a substrate pass through the frame 6, unnecessary high-frequency radiation noise is absorbed by bead cores 1 made of a ferrite. Since the grooves 5 of the cores 1 can be formed so that the grooves 5 can be easily engaged with projections 8 of a case 7 through packaging work, the workability can be improved. In addition, since the grooves 5 can be formed almost parallel to the two holes 2 and the thickness around the holes 2 become nearly uniform, no excessive strain is generated and the accuracy of the positions, shapes, etc., of the holes and the pitch length of the core 1 are improved. As a result, the absorbing abilities of the cores 1 become uniform. Moreover, since the thicknesses 1c of the groove 5 sections are slightly thicker than those 1b of the hole 2 sections and the side faces of the cores 1 are sloped, no excessive strain is generated at the time of extrusion molding and sintering. Therefore, the cores 1 do not crack during the manufacturing process and are not broken by residual strains.
