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. This inclined arrangement provides a space through which the cooling water intake pipe and the cooling water discharging pipe can extend. In a second embodiment, the surge tanks of the intake manifold are longitudinally offset to provide spaces in which the thermohousing of the thermostat mounted on the cooling water intake pipe and the cooling water discharging pipe can be mounted. In a third embodiment the axis of an auxiliary machine, such as a generator, is laterally offset from the centerline of the engine crankshaft to provide a gap and the cooling water pipe extends through the gap.

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.

摘要： A variable operating valve apparatus for an internal combustion engine that provides for improved combustion performance without enlarging the size of the cylinder head in the transverse direction. The variable valve mechanism includes a camshaft axially supported by the cylinder head, three-dimensional cams formed on the camshaft, a rocker shaft actuator able to displace the rocker shaft in the axial direction according to engine operating conditions, and a lift volume setting mechanism that changes the amount of valve lift dependent on the extent of positional change of the rocker shaft in the axial direction. The camshaft is at least axially supported on the intake port side of the cylinder head, a fuel injector (which injects fuel into the intake port) is installed to the part of the intake sidewall at the intake port of the cylinder head, and a concave part is formed into the intake sidewall above the fuel injector extending inward toward the camshaft.

摘要： The present invention offers a simple structure that facilitates the mounting of bearings, that maintains lubricating oil at a sufficient level in the bearing portions and that maintains an optimal distance between a rotor and a case housing for preventing freezing, for preventing reduction of the capacity and for preventing noise. Bearing stoppers provided between the bearings of the brushless motor and the bearing holders, which hold the upper end edge of each bearing, are secured at a projection formed at the internal circumferential surface of each bearing holder. A felt, which comes in contact with the lower portion of each bearing stopper and also comes in contact with the bearing at one side is provided, with holes communicating with the felt formed at the lower surface of the bearing stopper. In addition, the lower limit of the distance h between the lower end of the rotor and the upper end surface of the case housing is set at 1.5 mm. This prevents water from forming a connection between the rotor and the case housing due to capillary action and surface tension. In addition, the upper limit of the distance h is set at or under 8 mm, which represents the critical point for the capacity and the noise. This ensures that the capacity is maintained at a satisfactory level and also prevents noise from increasing. Moreover, a washer group, which comprises at least one each of a resin washer, a rubber washer and a POM (polyoxymethylene) washer is provided between a sensor magnet that is secured to the lower end of the rotating shaft and the lower bearing.
摘要翻译：本发明提供了一种简单的结构，其有助于轴承的安装，其将润滑油保持在轴承部分中的足够的水平，并且保持转子和壳体壳体之间的最佳距离以防止冻结，以防止容量的降低和防止噪音。设置在无刷电动机的轴承和保持每个轴承的上端边缘的轴承座之间的轴承止动件固定在形成在每个轴承座的内周面的突起处。与每个轴承止动件的下部接触并且在一侧与轴承接触的毛毡设置有与形成在轴承塞的下表面处的毛毡相通的孔。此外，将转子的下端与壳体的上端面之间的距离h的下限设定为1.5mm。这防止由于毛细管作用和表面张力而导致水在转子和壳体壳体之间形成连接。另外，距离h的上限设定为8mm以下，这表示容量和噪声的临界点。这确保了容量保持在令人满意的水平，并且还防止噪声增加。此外，在固定在旋转轴的下端的传感器磁体和下轴承之间，设置有包括树脂垫圈，橡胶垫圈和POM（聚甲醛）垫圈中的至少一个的垫圈组。
