    摘要： A semiconductor device includes an emitter region, a collector region provided directly under the emitter region, and a two-region base structure. The first base region is interposed between the emitter and collector regions, and the second base region supports the collector region. The aforementioned regions have a progressively higher impurity concentrations, with the collector region having an impurity concentration higher than that of the first base region, the second base region having an impurity concentration higher than that of the collector region, and the emitter region having an impurity concentration higher than that of the base region. Also included is a resistance region formed, in one embodiment, from a projecting end portion of one of the base layers. The projecting end portion of the base is fabricated so that both base portions contact one another in the resistance region, and consequently both base portions are of the same potential. Electrodes are also provided for ohmicly contacting the emitter, collector, and base regions. The two-region base structure enables the device to achieve a high resistance, and thus to achieve simultaneously a high breakdown voltage and a high frequency (speed) characteristic.

    摘要翻译： 半导体器件包括发射极区域，直接位于发射极区域下方的集电极区域和两区域基极结构。 第一基极区域插在发射极和集电极区域之间，第二基极区域支撑集电极区域。 上述区域具有逐渐变高的杂质浓度，其中集电极区域的杂质浓度高于第一基极区域，第二基极区域的杂质浓度高于集电极区域的杂质浓度，发射极区域具有杂质 浓度高于基区。 还包括在一个实施例中由一个基底层的突出端部形成的电阻区域。 基座的突出端部被制造成使得两个基部在电阻区域中彼此接触，因此两个基部都具有相同的电位。 还提供电极用于欧姆接触发射极，集电极和基极区域。 双区域基础结构使得器件能够实现高电阻，从而同时实现高击穿电压和高频（速度）特性。

    摘要： An engine includes an engine case split into an upper case and a lower case. A crankshaft and a transmission input shaft are rotatably supported at a mating surface between the upper and lower cases, and a transmission output shaft rotated by the transmission input shaft is supported in the lower case. One side face of the lower case has a circular opening through which the transmission output shaft can be inserted from the outside. An eccentric bearing holder holding a bearing that rotatably supports one end of the transmission output shaft is mounted in the opening in a detachable manner from the outside. The axis of the transmission output shaft deviates from the center of the eccentric bearing holder toward the transmission input shaft. The inner diameter of the opening is larger than the outer diameter of the largest one of transmission driving gears of the transmission input shaft.

    摘要： An engine for a motorcycle includes an engine case split in an upper case section and a lower case section. A mating surface between the upper case section and the lower case section extends linearly and inclines forward downward in a side view of the motorcycle. A crankshaft, a transmission input shaft, and a balancer shaft extending in the width direction of the motorcycle are rotatably supported at the mating surface, and a transmission output shaft rotated by the transmission input shaft is supported in the lower case section. The balancer shaft, the crankshaft, and the transmission input shaft are arranged in that order from the front side in the running direction of the motorcycle. The transmission output shaft is disposed below the transmission input shaft.

    摘要： When the claw of the engagement piece abuts the raised portion of the lock gear, the engagement piece cannot move further and is held off at the position. When the lock gear turns a small amount then the indentation (indented portion between gear teeth on the periphery) meets the claw. At this event, the slider piece moves as it is sliding along the guide cam by the elastic force of the coil spring until the slider piece abuts the spacer. The claw of the engagement piece meshes the lock gear so that the power output shaft is fixed or will not turn whereby the wheel shafts are locked.

    摘要翻译： 当接合件的爪邻接锁定齿轮的凸起部分时，接合件不能进一步移动并且在该位置处被保持。 当锁定齿轮转动少量时，凹口（外围的齿轮齿之间的凹进部分）与爪相遇。 在这种情况下，滑块随着螺旋弹簧的弹力沿着引导凸轮滑动移动，直到滑动件抵靠间隔件。 接合件的爪啮合锁定齿轮，使得动力输出轴固定或不会转动，从而轮轴被锁定。
