Title: Production of metal or alloy powder
Inventor: KATOU YOSHIYUKI
IPC: B22F9/08
Filed: 1993-05-19
Abstract: PURPOSE:To provide the production method of a metal or alloy powder which has a low oxygen content and is used for the powder metallurgy, injection molding, etc. CONSTITUTION:At the time of producing a metal or alloy powder by the water atomizing method, the molten metal or alloy is pulverized by allowing it to flow down from a nozzle and injecting into it high pressure atomized water contg. an oxidation inhibitor from an injection nozzle. Since the powder having a low oxygen content can be produced by using this method, the need for any special post treatment of the metal or alloy powder thus produced is eliminated and therefore the powder can be used as it is for injection molding, sintering, etc.

Title: Electrode for molten carbonate type fuel cell
Inventor: KOSEKI KAZUO
IPC: H01M4/86
Filed: 1987-06-03
Abstract: PURPOSE:To enlarge an effective electrode area so as to improve a cell output by using two layers consisting of one layer, which is large in its porosity on a side of an electrolytic plate, and another layer, which is small in its porosity on a side of a gas chamber, so as to form bilayer structure of electrodes which are pressed on an electrolytic plate containing an electrolyte of molten carbonate. CONSTITUTION:An anode electrode 3 and a cathode electrode 4 are pressed on a ceramics electrolytic plate 2. These electrodes are composed of layers 3A, 4A formed on sides of the electrolytic plate, and of layers 38, 48 formed on side of gas chambers, respectively. A mixture of copper, nickel, oxide, and the like is used as materials of the layers 3B, 4B, 3B, 4B. A roll molding method or the like is used to form these films. Next two of these layers are piled/rolled and fired in an atmosphere of hydrogen so as to be unified. Then porosities of the layers 3A and 4A become 75 to 85%, and those of the layers 3B and 4B become 60 to 75%. Hence the layers 3A and 4A are much adaptable to recessed and projected parts of the electrolytic plate 2, and so electrode output is improved. Creeping of the layers 3B and 4B hardly occurs and the porosities are not varied, so that electrode characteristics can be made stable.

Abstract: PURPOSE:To improve highly precise display of high horizontal deflection frequency and to make saw tooth current accurate by determining the polarity of a switching element and power source in the flow direction of reverse base current, and providing a reverse base current blocking circuit that prevent flow of reverse base current to an exciting transistor. CONSTITUTION:A signal P2 taken out from the collector of an driving transistor 2 is differentiated by a coupled resistor 22 and a coupled condenser 23 and supplied to an auxiliary driving transistor 21 as base current Ib. As time constant of a base bias resistor 24 and condenser 22 is selected to relatively small, the waveform of the base current Ib has large sag.

The signal P4 is supplied to an auxiliary driving transistor 26 through a coupled resistor 27 and make it conduct for a time tw4. Consequently, the reverse base current IB2 flows from the base of a transistor 4 to a negative power source -EB'.

Abstract: PROBLEM TO BE SOLVED: To miniaturize an air valve by equipping to a float valve element, a float main body lifted and lowered according to the change of a water level in a valve box, and a lever valve element which is pivoted to the float main body and whose valve seat abutting surface formed at the end thereof can be brought into contact with and separated from a small air hole valve seat. SOLUTION: A float main body 7a is lowered according to a water level, thereby a lever valve element 7b is moved downwardly by the principle of a lever around a contact point A, as a fulcrum, between a valve seat abutting surface 13a and a small air hole valve seat 6a, and a small air hole 6 is opened, so that air accumulated in a valve box 1 is automatically exhausted.  In this case, when air is accumulated in the valve box 1 at the time of flow and the water level in the valve box 1 is lowered, the float main body 7a is lowered according to the water level, and the lever valve element 7b is moved downwardly by the principle of the lever by the weight of the float main body 7a so as to open the small air hole 6, therefore the weight of the float main body 7a is increased by the principle of the lever so as to be applied to the lever valve element 7b, thus the float main body 7a can be diminished in size and an air value can be miniaturized.

Abstract: PURPOSE: To prevent a metal carrier material from excessively extending due to the components of a cocatalyst by heating the metal carrier material in an atmosphere to form an oxide coating film layer on the surface and further, forming a wash coat of a heat-resistant inorganic material bearing the components of the cocatalyst and a metal catalyst. CONSTITUTION: A metal carrier material comprises a flat plate 12 and a corrugated plate 14, formed of stainless steel sheet containing Al, which are laminated and wound around into a single piece. Further, the metal carrier material is heated in the atmosphere, and an oxide coating film layer 1 comprising Al2 O3 produced by oxidation of an Al component in the stainless steel sheet, is produced on the surface of the material. After that, a heat-resistant inorganic coating film comprising γ-Al2 O3 which contains cocatalyst components such as Ce, La and a wash coat 3 consisting of catalytic components such as Pt, Rh which are borne on the surface of the heat-resistant inorganic coating film, are formed as a coating film layer 5.  Thus it is possible to prevent the cocatalytic components from coming into contact directly with the metal carrier material, and also prevent the metal carrier material from excessive extension.
