摘要： A fault diagnostic system is arranged to detect faults in a fuel system of an engine with an electronic fuel injection system by monitoring the quantities of fuel consumed during a time interval. To do this, the consumption quantity of fuel is determined from a decrease of the residual quantity of fuel remaining in a fuel tank which is detected by a fuel gauge. On the other hand, the fuel injection quantity is determined independently by summing the length of the injector open time of each injection. Then, the fuel consumption quantity and the fuel injection quantity during the same time interval are compared. If the difference therebetween is larger than a predetermined permissible range, it is decided that there is some fault somewhere in the fuel system, and an indication signals is produced.

摘要： An ignition energy control method and system such that a high ignition energy is supplied to the spark plugs only while the engine is operating under an unstable condition. The unstable engine operating condition is determined by detecting the difference in the maximum engine speed within a predetermined crankshaft revolution angle or by detecting the low-frequency vibration generated by the engine. The ignition energy is controlled by calculating an appropriate pulse-width of an ignition signal or by changing a high voltage generating plasma within the cylinders. The ignition energy control system according to the present invention comprises a crankshaft angle sensor or a low-frequency vibration sensor, a calculating and storing means, and an ignition system including a plasma generating power supply where necessary.

摘要： A fuel control system for an internal combustion engine includes an exhaust gas sensor from which feedback control signal is derived, a limiter for limiting the maximum and minimum voltages of the control signal and a triangular wave generator. The triangular wave has a constant amplitude peak of which the maximum value is slightly greater than the maximum voltage of the control signal and the minimum value is slightly below the minimum voltage of the control signal. A comparator is provided to produce an output at one of two binary levels depending upon whether the control signal is above or below the instantaneous value of the triangular wave. The output from the comparator is a train of pulses whose duty cycle ranges from predetermined minimum to maximum values which correspond respectively to the minimum open and closure times of air-fuel mixing control valves.

摘要： In a wire-cut EDM apparatus for cutting a workpiece (2) submerged in a processing tank (3) filled with a machining fluid (15), an opening (24) is made in the side wall of the tank through which an arm unit passes. A slide plate (14) also has an opening for passage of the arm unit and also provents leakage from the space between the opening 24 and the arm unit. In one preferred embodiment a fluid flow between the slide plate and arm unit is used to prevent fluid in the tank from escaping through the space between the slide plate (14) and the arm unit. Alternatively, a low frictional member may be placed between the arm unit and the slide plate for axially sealing the arm unit. Frictional resistance from movement of the lower arm unit is reduced and machining accuracy improved.

摘要： A watchdog timer works in concert with special computer program features to monitor program execution and reset the computer in case of malfunction. The computer CPU is programmed to periodically output one of an alternating pair of values to a register which holds the value for a comparator. The output value is compared to a predetermined value equal to one of the alternating output value. When the compared values are equal, the comparator outputs a reset signal to a counter. The counter counts clock pulses and if it counts to its full capacity before being reset by the comparator output, it outputs a reset signal which causes the computer to restart program execution. A second comparator may be provided to compare the alternating values to a reference value equal to the other values. Thus the comparators check for proper output of both signals and reset the counter only in response to receipt of both values. In addition a second counting system may be provided so that the computer will be reset whether the period of alternating value output increases or decreases.

摘要翻译： 看门狗定时器与特殊的计算机程序功能一致，以监视程序执行情况，并在出现故障时重置计算机。 计算机CPU被编程为周期性地将一个交替的一对值输出到保持比较器的值的寄存器。 将输出值与等于交流输出值之一的预定值进行比较。 当比较值相等时，比较器将复位信号输出到计数器。 计数器计数时钟脉冲，如果在比较器输出复位之前计数其全部容量，它将输出复位信号，使计算机重新启动程序执行。 可以提供第二比较器以将交替值与等于其它值的参考值进行比较。 因此，比较器检查两个信号的正确输出，并仅在接收到这两个值时重置计数器。 此外，可以提供第二计数系统，使得计算机将被重置，无论交替值输出的周期是增加还是减少。

摘要： A throttle valve control system for an internal combustion engine electrically controls throttle valve angular position in order to control intake air flow rate through an air induction passage of an engine. The system employs an accelerator to produce a signal representative of a required or demanded output speed. Actual output speed is monitored by means of a speed sensor. The actual speed is compared with the output speed demand derived from the accelerator signal to obtain the difference therebetween. Feedback control is performed on the basis of the calculated difference so as to control the throttle valve angular position to increase or decrease the actual output speed toward the speed demand value.
