Patent JP-S6357870-A (JP)
Title: Fuel injection device
Inventor: TAIRA SHIGEO
IPC: F02M45/00
Filed: 1986-08-29
Abstract: PURPOSE:To surely decrease a rate of injection to a small value, by high holding the internal pressure in an injection pipe by a constant pressure valve while using a leakless nozzle holder in a fuel injection valve so that only a low speed region of a cam is used in the time of low speed and low load in no relation to cold and warm states. CONSTITUTION:Since fuel in a high pressure chamber 8 is pressurized by reciprocating a plunger 5 if a driving shaft 2 rotates, the fuel, passing through an injection pipe 14 to reach an injection valve 17, is injected from a nozzle 20 in accordance with a lift of a needle valve 24. Here a device, which holds the residual pressure in the injection pipe 14 to a high level by a constant pressure valve 16, increases the injection pressure of fuel in an injection valve 17 higher than the valve opening pressure in the point of time a cam 7 is in a small rotary angle. And in the time of low speed and low load, a rate of injection is small decreased by using only a low speed region of the cam 7. While in the time of high speed and high load, the rate of injection is large increased by using also a high speed region of the cam 7. While the injection valve 17, using a leakless nozzle holder 19, prevents the leakage of fuel, and the residual pressure in the injection pipe 14 is always held to a high level.

Title: Apparatus for measuring surface area
Inventor: WASHIO KAZUHIRO
IPC: G01N15/08
Filed: 1986-08-29
Abstract: PURPOSE:To prevent the generation of an artificial error or an individual difference, by automatically judging whether a short path or a long path is used in the measure ment of desorption during the measurement of adsorption and outputting the judgement result before desorbing treatment. CONSTITUTION:A judge circuit 33 judges whether the output signal of a flowmeter 32 and that of a thermal conductivity detector (TCD) 7 hold predetermined relation at the initial transient period of the measurement of adsorption to determine whether the change-over of a selector valve 14 is necessary prior to the measurement of desorption. That is, when a gaseous mixture accompanied by the change in a mixing ratio reaches the secondary side 7b of TCD 7 before the flow rate of the gaseous mixture returns to proper quantity during the transient period at the beginning of measurement, the selector valve 14 is automatically changed over immediately before the measurement of desorption is performed to select a long path 16 and, as a result, the measurement of desorption generating no error is performed and an accurate surface area value is obtained. When the gas acoompanied by the change in the mixing ratio reaches the secondary side 7b after the flow rate of the gaseous mixture returns to a proper range, the valve 14 is held as it is to perform the rapid measurement of desorption with the use of a short path.
