Patent number: 6048820Abstract: The invention relates to a copper-based catalyst with high activity and a long catalyst life and to a method of producing the catalyst. This catalyst essentially comprises copper oxide, zinc oxide, aluminum oxide, and silicon oxide and optionally containing zirconium oxide, gallium oxide, and palladium oxide, wherein with the total weight of the catalyst being taken as 100%, the above oxides account for, in the order mentioned, 20-60 weight %, 10-50 weight %, 2-10 weight %, 0.3-0.9 weight %, 0-40 weight %, 0-10 weight %, and 0-10 weight %, respectively, and the silicon oxide mentioned above has been derived from colloidal silica or dissolved silica in water, which catalyst has been subjected to calcination at 480-690.degree. C.Type: GrantFiled: March 9, 1998Date of Patent: April 11, 2000Assignees: Agency of Industrial of Sciences and Technology, The Reseach Institute of Innovative Technology for the EarthInventors: Masami Takeuchi, Hirotaka Mabuse, Taiki Watanabe, Michiaki Umeno, Takashi Matsuda, Kozo Mori, Kenji Ushikoshi, Jamil Toyir, Shengcheng Luo, Jingang Wu, Masahiro Saito

Patent number: 4315236Abstract: A sensor block is disposed within a package and includes a semiconductor diaphragm and a circumferential support bonded to the inside of the package. The semiconductor diaphragm is provided with at least one diffused resistor layer formed thereon as a pressure-sensitive element, one surface of the diaphragm being subjected to a reference pressure whereas the other surface is subjected to a fluid pressure to be measured. A diaphragm breakage detecting element including an electrical conductor filament is provided zigzagging back and forth laterally across the boundary between the diaphragm and the circumferential support, the point subject to maximum stress, the conductor filament material being of substantially the same mechanical strength as the diaphragm material, so that, when the diaphragm is broken, the conductor filament is also broken, thus allowing immediate indication of the diaphragm breakage.Type: GrantFiled: January 4, 1980Date of Patent: February 9, 1982Assignee: Nissan Motor Company, LimitedInventors: Tamotsu Tominaga, Teruyoshi Mihara, Takeshi Oguro, Masami Takeuchi

Patent number: 4314226Abstract: A pressure sensor having a silicon diaphragm whose opposite surfaces are subjected to fluid pressures for measurement. The diaphragm includes a diffused resistor as a pressure-sensitive element on a silicon base, a protective layer composed of a silicon epitaxial layer opposite in conductive type to the resistor and formed on the diffused resistor in order to prevent the resistor from being exposed to a corresponding fluid pressure, and an electrically insulating layer formed on an outer surface of the protective layer.Type: GrantFiled: January 4, 1980Date of Patent: February 2, 1982Assignee: Nissan Motor Company, LimitedInventors: Takeshi Oguro, Teruyoshi Mihara, Tamotsu Tominaga, Masami Takeuchi

Patent number: 4287501Abstract: A pair of semiconductor diaphragm blocks, each having a diaphragm on a front surface of which a diffused resistor is formed as a pressure-sensitive element, and a circumferential support integral therewith, are confined within a sealed hollow package and bonded at their circumferential supports to opposite inside surfaces of the package such that the front surfaces of the diaphragms are positioned within a vacuum space within the package. This package is provided with through holes through which fluid pressures subject to measurement are introduced so as to arrive at the back surfaces of the diaphragms.Type: GrantFiled: January 4, 1980Date of Patent: September 1, 1981Assignee: Nissan Motor Company, LimitedInventors: Tamotsu Tominaga, Teruyoshi Mihara, Takeshi Oguro, Masami Takeuchi

Patent number: 4276533Abstract: A diaphragm assembly includes a silicon diaphragm block which has a diaphragm at an eccentric position thereof, a diffused resistor formed as a pressure-sensitive element on a front surface of the diaphragm, and a silicon support plate bonded to the diaphragm block so as to cover a back surface of the diaphragm. The diaphragm assembly is accommodated sealingly within and bonded to the inside of a hollow package at an end portion of the assembly remote from the diaphragm in the direction of extension of the bonded surfaces of the block and the support plate. The front surface of the diaphragm and the diffused resistor thereon are exposed to a vacuum while a fluid pressure subject to measurement is introduced through a passage extending through the package and the end portion of the assembly bonded to the package so as to arrive at a back surface of the diaphragm.Type: GrantFiled: January 30, 1980Date of Patent: June 30, 1981Assignee: Nissan Motor Company, LimitedInventors: Tamotsu Tominaga, Teruyoshi Mihara, Takeshi Oguro, Masami Takeuchi
