Title: Ceramic product of sic quality for semiconductor manufacture
Inventor: HAYASHI TATEO
IPC: C04B41/89
Filed: 1989-09-27
Abstract: PURPOSE:To prevent the strength of an SiC film from deteriorating due to cracks by forming an intermediate buffer film of a given thickness on the surface of a base material consisting of a sintered body of an SiC quality and laminating the SiC film thereon. CONSTITUTION:A ceramic product of an SiC quality for a semiconductor manufacture is the one in which an intermediate buffer film of a carbon quality having the thickness of 0.2-20mum is formed on the surface of a base material consisting of a sintered body of the SiC quality and a dense SiC film is laminated on the intermediate buffer film. In this means, a residual stress when coating, a thermal stress and a mechanical stress generated in the SiC film are absorbed to be buffered by the lubricity and elasticity of the carbon quality forming the intermediate buffer film. When the thickness of the intermediate buffer film becomes thinner than 0.2mum, the effectness of the film that the extension of a crack is prevented is reduced. When the thickness of the intermediate buffer film becomes thicker than 20mum, the peeling of the film itself is caused easily.

Title: Gas-in-oil sensor
Inventor: MUKAI SADAYOSHI
IPC: G01N27/06
Filed: 1987-10-05
Abstract: PURPOSE:To accurately measure the hydrogen gas in oil, by coating the surface of a sensor main body with a membrane composed of a polyimide resin and further covering the sensor main body with a gas permeable film. CONSTITUTION:The surface of a sensor main body 4 is coated with a membrane 5 composed of a polyimide resin and further covered with a gas permeable film 11. The oil in a tank 6 is certainly blocked by the film 11 and does not reach the circumference of the sensor main body 4. Since the transmission coefficient of the film is large to hydrogen gas, said gas certainly transmits through the film 11. Since the transmission coefficient of the polyimide membrane 5 is large to the hydrogen gas as compared with other gas, the hydrogen gas in the gas transmitting through the film 11 selectively transmits through the polyimide membrane 5 to be brought into contact with the membrane 2 composed of metal oxide to be reacted therewith. By this mechanism, the surface resistance of the membrane 2 changes corresponding to the concn. of hydrogen gas. Therefore, by detecting said surface resistance as the resistance between the electrodes 3, the concn. of the hydrogen gas can be measured.
