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 optimally control supply of the air-fuel mixture to an internal combustion engine independently of a change of the fuel condition with consumption of the vapor-liquid fuel mixture.
SOLUTION: H/C ratio Rhc of the air-fuel mixture in the gaseous condition is computed on the basis of a detected concentration B of butane (S150). A theoretical air-fuel ratio Rt is computed on the basis of the H/C ratio Rhc (S200). A correction coefficient Ka of a fuel injection period is computed on the basis of the concentration B of butane and the theoretical air-fuel ratio Rt (S250). A basic fuel injection period Tb as the optimal fuel injection period when the natural gas is contained at 100 % is computed (S300). A first target fuel injection period T1 is computed on the basis of the basic fuel injection period Tb and the correction coefficient Ka (S400). A second target fuel injection period T2 for reducing a deviation between the real air-fuel ratio Ra and the theoretical air-fuel ratio Rt is computed (S450). A fuel injection period in relation to an air intake pipe 32 by a fuel injection device 28 is controlled on the basis of the final target fuel injection period Tt as the sum of the first and the second target fuel injection periods (S500, S550).

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 natural gas motor vehicle having an absorbed natural gas storage tank for improving the starting ability of an engine. SOLUTION: A buffer tank 18 is provided on the way of a pipe for supplying natural gas from a storage tank 10, in which absorbent is stored for absorbing and storing natural gas, to an engine 12 and a shut-off valve 20 is provided between the storage tank 10 and the buffer tank 18. During stopping of the engine 12, the shut-off valve 20 is closed and the buffer tank 18 is separated from the storage tank 10 for compression storage of natural gas under the then pressure. During next starting of the engine 12, natural gas under compression storage is supplied from the buffer tank 18 for starting the engine 12. Then, an engine cooling water increased in temperature is supplied to the storage tank 10 and the shut-off valve 20 is open when the pressure of a gas phase portion is over a preset value.

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.
