Abstract: PURPOSE:To obtain a thermal-spraying piston pin with an improved adhesion of a thermal spraying layer by giving a grit blasting to a light metal layer and applying thermal spraying onto the surface of said grit blasted light metal with a material having resistance to wear and seizing. CONSTITUTION:A cylindrical fiber-reinforced metal body 3 in which a reinforcing fiber of an alumina, etc., is arranged in the direction of a longer shaft and a light metal such as an aluminum, magnesium alloy, etc., is used as a matrix, is manufactured by means of a high pressure casting method. In this case, a matrix metal 4 forms the outermost layer of the metal body 3. A commercially available grit blasting material is applied to thus manufactured cylindrical fiber-reinforced metal body, to carry out grit blasting. After the grit blasting is completed, a thermal spraying layer 2 is formed on the surface of the light metal of the roughened outermost layer, with a material having resistance to wear and seizing such as a metal, a ceramic, etc., and the surface is polished, to manufacture a piston pin 1.

Abstract: PROBLEM TO BE SOLVED: To mix a liquid fuel of high inflammability with a gaseous fuel through safe pressurization. SOLUTION: In this fuel mixing and filling system 10, a gaseous fuel past a first fuel supply path 12 and a liquid fuel past a second fuel supply path 14 converge in a manifold 56 and then pass through a third fuel supply path 16 to fill a fuel tank 15 of a vehicle. The liquid fuel is supplied under pressurization by an air-driven booster pump 34. A drive part of the air-driven booster pump 34 is fed with compressed air generated by an air compressor 48. The air-driven booster pump 34 used to pressurize an inflammable liquid fuel can eliminate a risk of firing by an electric spark and pressurize the liquid fuel safely because of no electric system, and can be structurally compact because of no need for an explosion-proof structure.

Abstract: PROBLEM TO BE SOLVED: To provide a plate-like member for core in which making current for obtaining the same driving power is reduced, and an involute core using it. SOLUTION: A plate-like member 10 for a core which is disposed in radial or convolute manner for a center axis line Y of a core, to form a core is constituted with an oriented silicon steel plate, and an readily magnetized direction thereof agrees with the center axis line direction Y, and the member is formed into a U-shape provided with an opening end part in the center axis line direction. The ratio of a width (b) in a direction vertical to the readily magnetized direction to a width (a) which is narrower of two leg parts 18 and 20 in a direction parallel to the readily magnetized direction of the plate-like member 10 for core, is 1.4 or more. Thereby a loss in the direction vertical to the readily magnetized direction is smaller than that in the readily magnetized direction, so that an electromagnetic force in the case of the same making current can be made large.

Abstract: PURPOSE:To produce a sliding member having excellent wear resistance and seizure resistance by subjecting a rough shape material molded of hypereutectic Si-Al alloy powder to hot working and remelting the sliding surface thereof by irradiation of high-density energy then cooling the material at an adequate temp. decreasing rate. CONSTITUTION:The rough shape material of a bar shape, etc. is molded by preliminarily molding the hypereutectic Si-Al alloy powder. The sliding member having a prescribed shape is formed from such rough shape material by hot working after partial degassing or without making a degassing treatment at all. The high-density energy such as TIG arc or laser is irradiated to at least the sliding surface of the above-mentioned sliding member to remelt the surface and the molten surface is cooled at a temp. decreasing rate of 0.1-7.0 deg.C/sec. A sliding layer consisting of primary crystal silicon having 25-100mum grain size and 2-30% porosity is thus formed on at least the sliding surface down to the depth of >=0.1mm from the surface. The sliding member made by Al powder metallurgy having the improved wear resistance and seizure resistance and the excellent strength, toughness and heat resistance is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To suppress the magnitude of an eddy current which occurs in a core member to a small value and reduce the heat generating loss and effective magnetic flux loss of the member by constituting the member by bundling a plurality of thin wires of a soft magnetic material having an equilateral triangular, square, or regular hexagonal cross section and binding the outer periphery so as to secure the member in a specific shape. SOLUTION: A low-loss core member 10 is formed in a cylindrical shape. The member 10 is constituted by bundling a plurality of soft magnetic wires having a nearly regular hexagonal cross section and a length of l. The wires 12 are closely arranged by bringing the side faces of each wire 12 into contact with those of the other. After the wires 12 are arranged in a cylindrical shape, the cylindrical shape is maintained by binding the outer periphery of the member 10 with an outer periphery binding material 14. Therefore, any overcurrent which occurs in the member 10 becomes smaller and, therefore, the heat generating loss caused by the eddy current can be reduced.

Abstract: PROBLEM TO BE SOLVED: To improve filling accuracy and filling efficiency of gaseous fuel and liquid fuel. SOLUTION: A fuel mixing and filling system 10 performs preliminary filling control when a customer or an operator connects a filler nozzle 60 to a filler port 62 of a fuel tank 15 and inputs a filling quantity. The preliminary filling control fills the fuel tank 15 with gaseous fuel compressed to high pressure in a gas accumulator 18, and monitors a pressure change in the fuel tank 15 to compute a pressure rise rate. When a pressure gauge 58 measures a change in a pressure value in the fuel tank 15 due to the preliminary filling and a mass flowmeter 22 measures a flow rate of the filling gaseous fuel in the period, operation expressions can determine a residual quantity of gaseous fuel and a residual quantity of liquid fuel left in the fuel tank 15, and also estimate filling allowances of gaseous fuel and liquid fuel. Optimal control is thus possible for high accuracy and high speed filling and the like.

Abstract: PROBLEM TO BE SOLVED: To provide a natural gas automobile having an absorbing type natural gas storage tank capable of cooling an adsorbent making effective use of on- vehicle equipment at the time of charging natural gas. SOLUTION: Cooling water for an engine 12 is circulated by a water pump 22 to a storage tank 10 storing an adsorbent inside to adsorb and store natural gas which is fuel for the engine 12. In the case of charging the storage tank 10 with natural gas, an ECU 16 closes a control valve 20 to cut off the engine 12 from a cooling water circulating path, and cooling water cooled by a radiator 24 is supplied to the storage tank 10 and used to cool the adsorbent. The radiator 24 which is existing equipment can therefore be used to cool the storage tank 10 so as to dispense with an extra device.
