Title: Fuel injection device for internal combustion engine
Inventor: KAYANO KAZUO
IPC: F02D41/38
Filed: 1988-05-19
Abstract: PURPOSE:To enable fuel to be injected in an arbitrary injection rate and injection pressure by providing a means, which adjusts a pipe line for its releasing amount, and a means, which accumulates a surplus pressure of fuel, in the pipe line connecting a fuel plunger pump to an injection nozzle. CONSTITUTION:When a cam 2 rotates following action of an engine, a plunger 4 in a pump 3 moves. While being based on a detection signal from a crank angle sensor 38, a controller 40 closes a selector valve 12, disconnecting the communication of a high pressure passage 11 with a drain tank. Fuel in a pressurizing chamber 7 is pressurized, when a pressure is boosted in the high pressure passage 11, fuel of surplus pressure passes through a check valve 43 allowing the fuel to flow into an accumulator 45. On the contrary, being based on a detection signal from an engine speed sensor 39 or the like, because the controller 40 contracts a piezoelectric element 17, a throttle valve 20 in an adjusting chamber 14 is retracted. As the result, fuel is supplied passing through the adjusting chamber 14 and an injection passage 30 to an injection nozzle 31 performing pilot injection.

Title: Superconducting quantum interference device
Inventor: NAKANE HIDEAKI
IPC: H01L39/22
Filed: 1987-05-22
Abstract: PURPOSE:To prevent the lowering of sensitivity of a DC-SQUID (DC superconducting quantum interference device), by forming an adjustable resistance on a semiconductor substrate to improve accuracy or the like of a resistance value. CONSTITUTION:A semiconductor substrate 11 has such a concn. of impurities that a carrier freezes out to insulate itself under a very low temperature. A highly concd. impurities area 12 is provided at a part of the substrate 11. The degree of impurities is such that the carrier moves even under the very low temperature to be conductive electrically. Moreover, a gate insulation film 13 and a gate electrode 14 are provided on the back of the substrate 11. SQUID coils 1, a lamellar insulation film 7, an upper electrode 4 and the like are formed on such an area to make a DC-SQUID. When a voltage is applied to the electrode 14, the concn. of the carrier concentrating near the electrode 14 depends on a gate voltage. A resistance value between the time-shared coils is inversely proportional to the concn. of the carrier to make the resistance value controllable by the gate voltage. This ensures the optimum value of damping resistance for the DC-SQUID thereby enabling the prevention of malfunctioning.
