    • A starter for an internal combustion engine includes a power transmission mechanism. The power transmission mechanism has an outer race plate fastened to a crankshaft, and a ring gear coupled to a rotational shaft of an electric motor for starting the engine. The power transmission mechanism further has a one-way clutch for permitting torque transmission only from the ring gear to the outer race plate, and two sealing members. Lubricant is supplied from the cylinder block to the interior of the power transmission mechanism for lubricating the power transmission mechanism. The outer race plate has a groove on its contact surface of a contact portion between the crankshaft and the outer race plate. The groove extends in the entire circumferential direction of the crankshaft. This maintains the coupling strength between the outer race plate and the crankshaft, while enhancing the sealing performance of the power transmission mechanism.
    • 用于内燃机的起动器包括动力传递机构。 动力传递机构具有固定在曲轴上的外圈板,以及联接到用于起动发动机的电动机的旋转轴的环形齿轮。 动力传递机构还具有用于仅允许从环形齿轮到外座圈的扭矩传递的单向离合器和两个密封构件。 润滑剂从气缸体供给到动力传递机构的内部,用于润滑动力传递机构。 外座板在曲轴与外圈板之间的接触部分的接触表面上具有凹槽。 凹槽在曲轴的整个圆周方向上延伸。 这保持了外圈板和曲轴之间的联接强度,同时提高了动力传递机构的密封性能。

    • A microcontroller and a controlling system having the same are provided, in which the increase in the program code for performing floating-point arithmetic, in particular, the increase in the amount of code due to a variable are suppressed, and the processing overhead for converting fixed-point data into floating-point data is reduced. The microcontroller includes a floating-point converter which inputs integer data and corresponding decimal point position data as fixed-point data and which converts the input data into floating-point data by acquiring a fraction part, an exponent part, and a sign of the floating type from the input data, and a floating-point arithmetic logic unit which receives the output of the floating-point converter and calculates the floating-point data. The floating-point converter acquires the exponent part by performing addition and subtraction of the decimal point position data and the shift amount of the fraction part to the integer data.
    • 提供了一种微控制器及其控制系统,其中用于执行浮点运算的程序代码的增加,特别是由于变量引起的代码量的增加被抑制,并且用于转换的处理开销 定点数据进入浮点数据减少。 微控制器包括一个浮点转换器,它将整数数据和对应的小数点位置数据作为定点数据输入,并通过获取浮点数的分数部分,指数部分和符号将输入数据转换为浮点数据 从输入数据输入;以及浮点算术逻辑单元,接收浮点转换器的输出并计算浮点数据。 浮点转换器通过对小数点位置数据和分数部分的移位量进行加,减来获取指数部分到整数数据。
