Abstract: PURPOSE:To eliminate the decrease in a manufacturing yield due to an aluminum alloy spike and to accelerate a bipolar transistor by composing electrodes connected to bonded parts in a multilayer of an upper layer aluminum and an aluminum diffused barrier metal provided on the lower layer of the aluminum. CONSTITUTION:Electrodes connected to the bonded parts of transistors in a semiconductor device in which a bipolar transistor, an N-channel MOS transistor and a P-channel MOS transistor are integrally formed on the same semiconductor substrate 1 are composed in a multilayer of at least an upper layer aluminum 24 and an aluminum diffused barrier metal 23 provided on the lower layer of the aluminum 24.

Title: Plastic optical transmission fiber
Inventor: YAMAMOTO TAKASHI
IPC: G02B6/44
Filed: 1984-09-14
Abstract: PURPOSE:To obtain plastic optical transmission fibers which have the mechanical strength and the thermal resistance and are connected easily to inorganic glass optical fibers, by having certain relations among areas of a core layer, a sheath layer, and a protective layer. CONSTITUTION:The sectional area and the diameter of a core layer 1, those of a sheath layer 2, and those of a protective layer 3 are denoted as S1, D1, S2, D2, S3, and D3 respectively. The diameter of the core layer is 10-100mum, and the sectional area S3 of the protective layer is equal to (0.2-80) (S1+S2). A degradation is recognized with respect to the optical transmission characteris tic mainly if the coefficient exceeds 80; and especially, if the sheath layer is made thinner for the purpose of making the protective layer thicker, the optical transmission loss is increased considerably. The lower limit is set to 0.2 because the protective layer is too thin relatively to obtain required characteristics with respect to mechanical strength and thermal resistance if the coefficient is smaller than 0.2.

Title: Heat carrying device
Inventor: NAWA MOTOYUKI
IPC: F25D9/00
Filed: 1988-07-29
Abstract: PURPOSE:To control the generation of noise and vibration to widen an ability control range by enclosing refrigerant in which particulates of ferromagnetic material is colloidally dispersed as if there is electric conductivity in a fluid closed circuit. CONSTITUTION:Refrigerant in which particulates of ferromagnetic material is colloidally dispersed as if there is electric conductivity is enclosed in a pipeline 6. An electromagnetic force driving unit 2 is formed so that magnetic field and current are applied to the refrigerant at right angles each other in a right- angled plane in the direction of the flow of the pipeline 6. When a heating means 18 is turned on, driving force works on colloidal particulates of the refrigerant, which moves in the direction of an arrow mark A in the electromagnetic force driving unit 2. Heat releasing and heat absorbing are performed and heat carrying is formed in a first heat exchanger 3 and a second heat exchanger 4. Thus, since the refrigerant is carried by the action of the magnetic field and the current, noise and vibration is not generated and further an ability control range can be widened.

Title: Method of measuring thickness of cable coating
Inventor: KUWAMOTO KAZUHIRO
IPC: H02G1/14
Filed: 1981-11-30
Abstract: PURPOSE:To obtain data on the thickness of coating quickly and to cope with thickness deviation therein by a method wherein the true thickness of coating is individually obtained by the correction coefficient of the thickness using ultrasonic waves. CONSTITUTION:Since the outside diameter d of a core and the D of a cable have been correctly measured, the value D-d, or what is obtained by subtracting the outside diameter d of the core from that D of the cable is equal to the sum of th true thicknesses a', b' of the cable coating a'+b'. On the other hand, the measured thicknesses a, b of the cable 5 are proportional to the true thicknesses a', b', so that the coefficient of correcting the measured thicknesses a, b of the coating. Accordingly, the true thicknesses a', b' can be obtained by multiplying the measured values a, b by the correcting coefficient. Thus a combination of the measurement of the cable coating ticknesses a, b using ultrasonic waves and the measurement of the outside diameter D of the cable 5 and that d of the core makes it possible to individually obtain the true coating thicknesses a', b' of the cable immediately after its extrusion and thus to use the coating thickness for the control of the cable extrusion line. If the number of ultrasonic sensors 3' is increased, more reliable accuracy will be available.

Title: Hot restart fuel feeding device for internal combustion engine
Inventor: KOBAYASHI HIROTO
IPC: F02M25/08
Filed: 1985-09-02
Abstract: PURPOSE:To facilitate a hot restarting by connecting a pipe, which feeds vaporized fuel in a fuel tank to an engine, to a section adjacent to the fuel tank and the suction port of a suction pipe so that the pipe is normally closed but is opened when a hot restarting is required. CONSTITUTION:On start-up of an engine, a crank shaft 34 is rotated by means of a recoiling device 30, and a starting plunger 63 is simultaneously pulled to the left. This causes a jet 69 to open so as to open an air intake 61a. Then, vaporized fuel 63a in the upper space of a fuel tank 1 flows passing through a passage 51, the jet 69, and a passage 51a, and is mixed with air from an air inlet 61a at an opening 54a between a carburetor 2 and an engine 27, and is further fed to the engine 27 so as to start the engine 27. While the engine is being operated by the vaporized fuel 63a, the carburetor 2 is cooled by heat of vaporization of the fuel allowing liquid fuel in the tank 1 to be fed to the carburetor 2 through a fuel pipe 9 for shifting the engine to a normal operation. With this, a hot restarting can be positively effected in a simple manner. The device is suitable to a chain saw and a lown mower.

Patent JP-H0636625-A (JP)
Title: Superconductor
Inventor: MINATO TSUNEAKI
IPC: H01B12/02
Filed: 1992-07-20
Abstract: PURPOSE:To enable a superconductor of steady conductive state to easily return to superconducting state by restraining a current flow across stabilizing materials, while a part of a boundary between the materials being divided with an insulation material. CONSTITUTION:An insulation material 8 such as polyamide resin is laid at a boundary between copper 1 and aluminum 4 as stabilizing materials. When a superconductor turns into steady conductive state due to an instantaneous temperature rise, electrical current flows across the aluminum 4 or copper wires 4 and 5 having low electrical resistance, and not across a superconducting wire 2. Consequently, electrical field is generated within the cross section of the superconductor, due to the interaction of current and magnetic field. In this case, the copper 1 and the aluminum 4 are electrically isolated from each other with an insulation material 8 and, therefore, no current is generated within the section, thereby reducing the calorific value of generated heat. As a result, the superconductor returns to superconducting state and allows electrical current to flow as original.

IPC: C02F11/04
Filed: 1988-08-02
Abstract: PURPOSE:To enhance safety by equipping a filter mechanism for removing impurities in gaseous methane generated in a fermentation tank, a water seal mechanism and an overflow mechanism. CONSTITUTION:When abnormal pressure acts on both a methane fermentation tank 1 and a gas holder 2, liquid level (f) is lowered to liquid level (b) and liquid level (g) is raised to liquid level (c). Water exceeding the liquid level (c) is passed through the pipelines 39, 35 from the upper end of the pipeline 39 and discharged through an overflow hole 36. Furthermore when pressure is raised and exceeds the maximum allowable pressure of the gas holder 2, water seal is broken and gaseous methane is passed under a lower end part 43 from a fourth chamber 19 and discharged to the atmosphere via a fifth chamber 20 and a pipeline 34. At sn abnormal time of negative pressure, a state is made reverse to this case. A pipeline for deciding the maximum allowable pressure of the methane fermentation tank 1 is provided to the final part of a water seal mechanism and safety is enhanced.
