Title: Method and apparatus for vacuum inspection
Inventor: INOUE MASASHI
IPC: G01M3/24
Filed: 1995-06-20
Abstract: PURPOSE: To realize an easy and accurate inspection without requiring any large scale intricate facility by vacuum sucking a vacuum box to an object and collecting sound in the vacuum box under suction. CONSTITUTION: Upon operation of a vacuum pump 27, the space defined by a vacuum box 21, a sealed part 22 and the face plate 11 of an object is evacuated and an inspection is made under evacuation. When a through defect 9 is present in the face plate 11, the air is sucked into the box 21 to produce rubbing noise. The rubbing noise is caught by a sound collector 31 and amplified through a decision unit 32 and then a decision is made whether the through defect 9 is present. When a defect is detected, a display 33 lights a light emitting element corresponding to a sound collector 31 detected the defect and an audible alarm is delivered from an alarm generator 34. A worker puts a mark on a part currently applied with the box 21. Upon finishing the inspection, a through defect is found with reference to the mark and a repair work, e.g. welding, is performed.  A printer 35 prints the inspection results.

Title: Semiconductor device
Inventor: SHIBATOMI AKIHIRO
IPC: H01L29/80
Filed: 1980-10-31
Abstract: PURPOSE:To enhance the characteristics of a Schottky barrier type field effect transistor SB-FET by forming an active layer on a semi-insulating or high resistance, eptaxial crystal layer, and reducing the effect of impurities which form a deep inpurity level. CONSTITUTION:A non-doped semi-insulating GaAs crystal is obtained by a gaseous phase epitaxial method employing Ga-AsCl3. When said crystal grawth exceeds certain level, impurities (Cr, O) in a substrate is added and the background impurity level shown by a solid line is generated. When the surface is approached, impurity density is lowered as shown by a dot and dash line. TBE in the Figure is the thickness of the non-doped layer wherein the background level is generated. The thickness of the epitaxial layer for the Schottky barrier type FET is set as TBE+TD, where TBE is 0.5-10mum, and TD is 0.2- several mum. TD is the thickness of the region formed by the impurities which are diffused from the substrate to the surface side of the epitaxial layer in the heat treatment for activation after ion implantation. The excellent FET characteristics can be obtained in this way.

Abstract: PURPOSE:To improve watertightness and peeling property by filling a mixture of a vinyl acetate-vinyl chloride copolymer and an ethylene-vinyl acetate copolymer having respective specified mixing ratios and Ml values into a cavity between stranded conductors. CONSTITUTION:It is necessary that a watertight mixture 1 used in an outdoor vinyl chloride insulated wire has a mixing ratio of 5-30095-70 by weight of vinyl acetate-vinyl chloride copolymer to ethylene-vinyl acetate copolymer.
