Patent number: 6733732Abstract: A reactor comprising a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, having a gas-diffusing member provided in an internal space of the body, and having a platinum coating on an internal wall surface of the body. Hydrogen and oxygen fed from the inlet are diffused by the gas-diffusing member and then come into contact with the platinum coating to enhance reactivity, thereby producing water. A temperature of the reactor is held to be below an ignition temperature of hydrogen or a hydrogen-containing gas. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wall surface, and forming the platinum coating on the barrier coating.Type: GrantFiled: February 15, 2001Date of Patent: May 11, 2004Assignees: Fujikin IncorporatedInventors: Tadahiro Ohmi, Koji Kawada, Yoshikazu Tanabe, Takahisa Nitta, Nobukazu Ikeda, Akihiro Morimoto, Keiji Hirao, Hiroshi Morokoshi, Yukio Minami

Patent number: 6622543Abstract: A gas detection sensor permits precise measurement of the concentration of flammable gas in a detection or subject gas and the concentration of oxygen in a detection gas containing flammable gases. In the sensor, the heating of the sensor by contact catalytic reaction of flammable gas gives off a detection signal of the flammable gas. The gas detection sensor has a first detection sensor including a diaphragm having a platinum coat on a side which the flowing detection gas comes in contact with, and a thermocouple having respective ends of two different metals placed close to each other and fixed on the side of the diaphragm not coming in contact with the flowing detection gas and which is heated by the contact catalytic reaction of flammable gas. A second detection sensor similar to the first detection sensor detects the temperature of the flowing detection gas.Type: GrantFiled: November 15, 2001Date of Patent: September 23, 2003Assignees: Fujikin IncorporatedInventors: Tadahiro Ohmi, Kouji Kawada, Nobukazu Ikeda, Akihiro Morimoto, Yukio Minami, Katunori Komehana, Teruo Honiden
