Title: Inspection of surface defect
Inventor: BABA TOSHIYUKI
IPC: G01B11/30
Filed: 1988-10-07
Abstract: PURPOSE:To make it possible to inspect stably even a defect having a directional property by illuminating the inspection surface of a workpiece in parallel and uniformly from the surroundings and by receiving a scattered light from the inspection surface from the direction vertical to the inspection surface by an image pickup device. CONSTITUTION:A ring illuminator 11 is so provided that it surrounds an inspection surface 13 and that a light-emitting element (glass fiber) 12 is positioned at the same height with that of the inspection surface 13. The inspection surface 13 is illuminated in the horizontal direction from the surroundings by the light-emitting element 12, and therefore the condition of illumination being irrelevant to the direction and the position of a defect 14 formed on the inspection surface 13 is obtained. A TV camera 15 picks up an image of the inspection surface 13 from the vertical direction, and image of the defect is picked up brightly on the original image, since a scattered light increases at the defect 14. An image processing device 16 subjects the original image to a differential processing and thereby a part between a defective part and a normal part, in which density changes sharply, is emphasized. By subjecting the part to binary-coding at an appropriate slice level, accordingly, the defective part can be extracted stably on an binary-coded image. The characteristic feature of the size of the defect 14 is determined from this binary-coded image, so as to execute inspection.

Title: Gasket
Inventor: MATSUOKA HIROSHI
IPC: F16J15/12
Filed: 1987-10-07
Abstract: PURPOSE:To provide a gasket which withstands high temperature and is hard to be oxidized by forming a thin film of metal or metallic oxide on the surface of a gasket main body formed by molded graphite. CONSTITUTION:As the surface of a gasket main body 42 formed by graphite is covered with a thin film 43 of metal or metallic oxide, even if a gasket is exposed to oxidizing atmosphere, oxidization of the gasket main body 42 can be checked by the thin film 43 of metal or metallic oxide. As metal such as nickel, copper or the like or metallic oxide forming the thin film 43 is comparatively excellent in heat-resistance and even if it is oxidized in oxidizing atmosphere, it is chemically and mechanically stable, the coat checks oxidization of the gasket main body 42 and reinforces fragility of the gasket main body 42 so as to maintain durability.
