    • A power supply for an electroerosion machine having a switching element which controls the machining current in the gap. The value of the current is compared with a predetermined voltage and the signal generated based on this comparison is provided to a logic gate, advantageously an "AND" gate, whose output signal is applied to the control electrode of the switching element. The power supply supresses any arcing tendency during the gap short circuit conditions and increases the total current through the gap even when gap voltage is low in order to maintain a high machining rate. Electrode consumption is reduced by using a generally step-type current waveform signal. Machining current during the discharge period may be controlled to more closely approximate a square wave so that shifting to a faster machining rate can be easily accomplished by accepting some sacrifice in electrode consumption. Preferably, two or more switching and gating devices are used to permit gap current to flow intermittently during the entire discharge period.
    • 一种用于电腐蚀机的电源,其具有控制间隙中的加工电流的开关元件。 将电流值与预定电压进行比较,并将基于该比较产生的信号提供给逻辑门,有利地是“AND”门,其输出信号被施加到开关元件的控制电极。 电源抑制间隙短路条件下的任何电弧倾向,即使间隙电压较低,也可增加通过间隙的总电流,以保持较高的加工速度。 通过使用大致阶梯式电流波形信号来降低电极消耗。 放电期间的加工电流可以被控制得更接近于方波,从而通过接受电极消耗的一些牺牲,可以容易地实现转换到更快的加工速度。 优选地,使用两个或更多个开关和门控装置来允许间隙电流在整个放电期间间歇地流动。

    • A motorcycle includes a rear fork with a first and the second extending portions, and a cross portion, the cross section linking the first and the second extending portions together. The first extending portion extends toward a first side of a rear wheel, the second extending portion extends toward a second side of the rear wheel. The first extending portion, which has an open cross sectional structure and through which a drive shaft is passed, is made to have larger outer diameter than the second extending portion, which has a closed cross sectional structure. Nonetheless, the rigidity of the first extending portion and the second extending portion are approximately the same. The drive shaft extends rearwardly and passes through the opening on the inside of the first extending portion.

    • A motorcycle includes a vehicle body frame, an engine, a pivot shaft, a swing arm, a rear wheel, a gear case, a drive shaft section, and a bearing section. The drive shaft section includes a first drive shaft connected to an output power shaft of the engine through a first universal coupling and a second drive shaft disposed coaxially with the first drive shaft and connected to the first drive shaft through a spline portion to be movable in an axial direction with respect to the first drive shaft. The bearing section restrains relative movement of the first drive shaft and the second drive shaft along a diametrical direction. The bearing section is interposed between an inner circumferential face of one of the first drive shaft and the second drive shaft and an outer circumferential face of another of the first drive shaft and the second drive shaft.

    • A shaft of a pinion gear is engaged with a ring gear extends toward the front side in a final gear case that is provided in a power transmission system between a power unit and a wheel. Splines are provided on each of an outer circumference of the shaft, and on an inner circumference of a cylindrical portion of a pinion joint that forms a receiving portion of a joint provided at the rear end of a drive shaft for transmitting power from the power unit to the pinion gear. The two splines are engaged with each other. The pinion joint is fixed to the pinion gear by a bolt that is threadedly engaged with a threaded portion formed at the lower portion of a hole in the pinion gear shaft. A flexible portion of the bolt is formed between a head portion and the threaded portion of the bolt.

    • A motorcycle is provided with a rear fork attached to a body frame so as to swing up and down freely. A rear wheel is attached to the rear end portion of the rear fork, a gear case is attached to a side of the rear wheel, and a drive shaft is provided between the gear case and an output shaft of a power unit. The output of the power unit is transmitted to the rear wheel via the drive shaft and the gear case. In the motorcycle, the gear case is supported by a rear-wheel axle provided in the rear end portion of the rear fork. A torque rod, which links an outer periphery portion of the gear case with the rear fork, serves as a stopper for rotation of the gear case. The resulting configuration provides a shaft-drive system that reduces the assembling time of the torque rod, and improves the productivity of the main line.
