摘要： A motor assist apparatus for a vehicle having a motor for assisting driving force of an internal combustion engine. The motor assist apparatus is built in a motor housing installed between a cylinder block of the engine and the case of the transmission. The motor housing has a length in the cylinder line direction which is equal to the distance between the centers of cylinders of the engine. As a result, the motor assist apparatus can utilize a part of an engine with one more cylinder when adapting the motor assist apparatus to the vehicle engine.

摘要： In order to protect a brushless motor, heat generated at a switching device, in response to an abnormality, activates a protection device. The protection device includes a connecting line communicating between a source supply line and the switching device. The protection device is provided near the switching device such that it can sense heat at the switching device with a high degree of sensitivity. Thus, when excessive heat is generated at the switching device, the protection device reaches a specific temperature, whereby the source supply line becomes cut off from the switching device, thereby immediately stopping the operation of the brushless motor.

摘要： The present invention provides apparatus and a process for efficiently removing particles generated during a laser marking of the semiconductor wafer substrate, thereby improving the yield. The process of the invention for marking a semiconductor wafer substrate by a beam of laser radiation comprises the steps of flowing a gas over a marking region at a predetermined flow rate and removing the gas from the marking region at the same predetermined flow rate, thereby generating a gas flow having a predetermined flow rate over and adjacent the marking region so that particles produced from the semiconductor wafer substrate while it is being marked will be removed. In a preferred embodiment, the semiconductor wafer substrate may be mounted with its upper surface to be marked directed downwardly while the laser marking beam is directed upwardly to the substrate.

摘要： An object of preventing a reduction in the output efficiency of a motor in the high speed rotation range and reducing the noise of the motor in the low speed rotation range is to be achieved. Since, if a signal that corresponds to the rotation rate has a value equal to or smaller than a specific value, the timing with which a switch performs switching is retarded relative to the timing used when the signal corresponding to the rotation rate has a value larger than the specific value, once the operation shifts to the low speed rotation range, the switching timing is retarded to shift from the setting that gives priority to efficiency, to the setting for achieving noise reduction as long as the switching timing is set in advance so that an optimal output efficiency is achieved in the high speed rotation range.

摘要： A V-engine for permitting the engine to be more compact and easy to assemble and to improve engine cooling performance. In a first embodiment, the branch pipes of the intake manifold of the engine extend at an acute inclined angle with respect to the centerline of the crankshaft.

摘要： A pulse width of a drive pulse of a brushless motor is modulated in correspondence to a setting signal for setting the rotation rate. Switching control for the current supplied to exciting coils is implemented by using an output signal from Hall elements for detecting the position of the rotor and the drive pulse. Correction of the pulse width of the drive pulse is implemented to ensure that the average voltage is maintained at a constant level even when the source voltage fluctuates so that stable rotation can be maintained over the entire rotation rate range even when the source voltage supplied to the brushless motor fluctuates and so that the fuse can be prevented from melting and the motor can be prevented from becoming damaged, which may otherwise be caused by a fluctuating source voltage.

摘要： A pulse motor control device comprises, as additional component parts, a power-off detecting circuit, and a turning-off circuit. The power-off detecting circuit detects, when a driving switch is turned off, a dropping of a voltage supplied to a driving circuit and outputs a power-off detection signal. The turning-off circuit includes diodes and a control resistor. The diodes are connected respectively to control terminals of all driving transistors of the driving circuit. When the control transistor is turned on in response to the power-off detection signal, voltages of control terminals of the driving transistors are dropped to the ground level through the diodes, thereby turning off the driving transistors.
