Title: Combustion catalyst
Inventor: SHINDO HITOSHI
IPC: B01J23/44
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a combustion catalyst exhibiting satisfactory purification performance and having a long life. SOLUTION: The surface of a carrier, through which the mixed gas of fuel and air is passed, is coated with a coating material. Catalysts 2, 3 are produced by dispersing a catalytically active substance in the coating material. The combustion catalyst is constituted by arranging the catalysts 2, 3 upstream and downstream of the flow of the mixed gas. In this case, the coating material of the catalyst 3 in the downstream part is constituted of such coating material that both the phase of the coating material of the catalyst 2 in the upstream part and a stable phase having a specific surface area smaller than that of this phase are mixed. Thereby, a stable phase having a small specific surface area is mixed in the catalyst 3 in the downstream part.  Accordingly, the phase transition of the coating material of the catalyst in the underflow part at a high temperature is prevented and the life of the catalyst is prolonged.

Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To control a compressor so as to improve derivability by turning off an electromagnetic clutch when a sucked air temperature of the second unit reaches a predetermined temperature. SOLUTION: A compressor 1 is connected to an engine 2 via an electromagnetic clutch 40, and the electromagnetic clutch 40 is controlled so as to be turned on/off by means of a control unit C, to which a signal from a temperature sensor SE1 detecting a temperature (intake temperature) of sucked air of the second unit 20 is inputted.

Title: Refractive index guiding type semiconductor layer and its manufacture
Inventor: HAMAGUCHI YUICHI
IPC: H01S5/00
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To enable an AlGaAs refractive index-guiding type semiconductor laser having a ridge structure to conduct refractive index guiding, even when through no high-refractive index layer having a small Al composition is provided in the ridge. SOLUTION: After a p-AlGaAs clad layer 4 and a contact layer 6 have been successively formed on an active layer 3, a ridge section R is formed by partially etching the layers 4 and 6. Then a refractive index-guiding layer 9, composed of AlGaP or AlGaAsP and having a small refractive index, is formed in the surface part of the clad layer 4 by having phosphorus (P) diffuse in the surface part. Thereafter, a ridge section R is embedded by forming a current constructing layer 7 by growing crystals. As a result, since the guide layer 9 is able to conduct refractive index guiding and at the same time, exhibits a current constricting effect, it becomes unnecessary to increase the concentration of an n-type dopant in the current constricting layer 7 so high.
