摘要： A wire-cut electric discharging machine comprises a processing tank with an opening in one wall for the insertion of the lower arm unit. The lower arm unit is enclosed by a cylindrical pipe. The opening in the wall of the tank is sealed by a slide plate which moves in a direction parallel to the wall of the tank. Bellows interconnect the slide plate to the pipe 10 thereby providing a seal between the slide plate and pipe. The bellows expand and contract thereby allowing the processing tank to move along the axis of the lower arm unit while still providing a seal. Machining fluid flows through the pipe and around the lower arm unit. The fluid maintains the temperature of the lower arm unit at a constant value. The pipe protects the lower arm unit from being directly affected by the hydraulic pressure in the tank and also from being affected by motion of the tank. The sealing resistance for when the processing tank moves along the axis of the lower arm unit is significantly reduced.

摘要： A method and apparatus for controlling fuel to be supplied from a motor-driven fuel pump to fuel injection valves of a fuel injected engine, the time period during which the fuel injection valves are kept open and the power duty cycle for driving the fuel pump motor are both calculated by a microcomputer responsive to one or more engine operating conditions. Reduced power consumption of the pump motor is achieved, thus resulting in reduction in the load applied to the battery and therefore improving the fuel consumption rate. The apparatus comprises an input unit, an injector drive unit, and a pump drive unit in addition to the microcomputer, and includes circuits for converting both the time period and the power duty cycle according to the battery voltage and the degree of engine acceleration.

摘要： A feedback air fuel ratio control system or method for a multi-cylinder engine is arranged not only to control the average value of the air fuel ratios among the cylinders but also to control the individual air fuel ratio of the individual cylinders so as to level the cylinder to cylinder air fuel distribution. This is done, for example, by directly detecting which cylinder is a source of the air fuel deviation by examining the oxygen sensor signal fluctuation in relation of time and individually regulating a fuel injector for that cylinder. In the case of an engine with a carburetor, the carburetor is controlled in relation with time in accordance with the sequence of the intake periods of the individual cylinders to control the individual air fuel ratio.

摘要： A method and system for correcting engine ignition timing without the use of any pressure sensor or vibration sensor and depending upon engine knocking is disclosed. The presence or absence of knocking is determined by reference to the rate of change of engine speed. This method is based on the fact that engine speed changes abruptly when engine knocking occurs, as compared with the normal engine condition, because of abrupt changes in pressure within the cylinders. The system of the present invention comprises an crankshaft angle sensor to generate a crankshaft angle pulse signal, a period measuring means to output an interrupt request signal and to determine the presence or absence of engine knocking, a microcomputer, and an ignition signal generator for outputting an ignition signal in accordance with an ignition timing signal and a dwell angle signal.
