摘要： A fuel injection apparatus for an internal combustion engine is provided which is designed to control a fuel discharge from a fuel injection pump by regulating the quantity of fuel sucked into the fuel injection pump. The fuel injection pump is driven in synchronism with rotation of the engine to pressurize and supply the fuel to an accumulator chamber from which the fuel is injected into cylinders of the engine. The solenoid valve moves a valve member linearly to open and close a fluid path leading to the fuel injection pump. The controller actuates the solenoid valve in one of a first control mode when the engine speed is low and a second control mode when the engine speed is high. In the first control mode, a valve on-duration in which the solenoid valve is turned on to open the fluid path through the valve member and an area of the fluid path opened by the valve member are both controlled. In the second control mode, only the opened area of the fluid path is controlled. This achieves fine adjustment of quantity of fuel discharged from the fuel injection pump over a wide range of engine speeds.

摘要： In an electromagnetic valve, after a solenoid assembly, in which a housing surrounds an outer circumference of a solenoid composed of a coil and a bobbin and a resin connector is formed on the housing by injection molding, and a valve body assembly, in which a valve body member is slidably housed to move reciprocatingly in a valve case cylindrical hollow of a valve case member, are independently sub assembled, the valve body assembly is integrated with the solenoid assembly in such a manner that the valve case member is axially inserted into a cylindrical hollow of the bobbin and, then, an axial end of the housing is fixed to an outer circumference of the valve case member by crimping. Accordingly, if a malfunction of a component part occurs during manufacturing processes, less number of component parts are rejected as failure.

摘要： An optical modulator and an optical transmission system convert continuous light of a multiple wavelength light source, which generates the continuous light with a fixed and complete phase but different frequencies, to a modulator driving signal so as to generate a light subcarrier with each frequency at the center and modulate the continuous light to the light subcarrier by using the modulator driving signal. In the case where an optical modulation is carried out by an optical IQ-modulator, transmitting data, for example, is converted to two parallel data A(t) and B(t), an I phase signal, in which the data A(t)+B(t) are modulated with a clock signal with a frequency ω, and a Q phase signal, in which the data A(t)−B(t) are modulated with a clock signal with a π/2 phase shifted, are generated, and the I phase signal and the Q phase signal are applied to electrodes of the optical IQ-modulator, respectively.

摘要： In a fuel injector, a body has formed therein a spray hole and a fuel supply passage. Fuel supplied to the fuel supply passage is delivered to the spray hole. A fuel pressure sensor produces a signal indicative of a pressure of the fuel. First terminals are attached to the fuel pressure sensor, and include a terminal for outputting the signal. The fuel pressure sensor is threadedly installed in the body while the plurality of first terminals are rotated about a preset axis. A connector includes a housing attached to the body, and second terminals supported by the housing for external electric connection of the fuel pressure sensor. Electrodes are each arranged to extend around the preset axis in a circular arc. Each of the electrodes electrically connects a corresponding one of the first terminals to a corresponding one of the second terminals.
