    摘要： In the ground fault detecting circuit, one terminals of first to third resistance elements are connected to first to third AC lines, respectively, the other terminals of the first to third resistance elements are commonly connected to one terminal of a fourth resistance element, and the other terminal of the fourth resistance element is connected to a line of a ground voltage. On the basis of a voltage across the terminals of the fourth resistance element, the ground fault detecting circuit detects whether a ground fault has occurred or not. Since a current does not flow through the fourth resistance element in the normal state and flows through the fourth resistance element after the occurrence of a ground fault, it is possible to detect the occurrence of the ground fault at a high accuracy.

    摘要翻译： 在接地故障检测电路中，第一至第三电阻元件的一个端子分别连接到第一至第三交流线路，第一至第三电阻元件的另一个端子共同连接到第四电阻元件的一个端子， 第四电阻元件的另一端子连接到接地电压线。 基于第四电阻元件的端子两端的电压，接地故障检测电路检测接地故障是否发生。 由于在正常状态下电流不流过第四电阻元件，并且在发生接地故障之后流过第四电阻元件，因此可以高精度地检测接地故障的发生。

    摘要： This thyristor starter includes a control angle operation portion including a function or a table showing relation between a rotation speed of a synchronous machine and a phase control angle of an inverter and finding a phase control angle having a value in accordance with the rotation speed of the synchronous machine found by a speed operation portion. The phase control angle varies from a minimum value to a maximum value in accordance with the rotation speed of the synchronous machine, and a rate of increase in phase control angle relative to the rotation speed of the synchronous machine is varied in a plurality of steps in accordance with the rotation speed of the synchronous machine.

    摘要： An encoder structure includes a sensor head unit 6 installed in an irrotational part, a rotative magnetic ring unit 4 that is positioned close to the sensor head unit 6 and has a north pole and a south pole arranged alternately on a circumference thereof, and a groove unit 7 formed in at least one of spaces between the north pole and the south pole located on a surface of the magnetic ring unit 4. Thus, deposits such as iron particles are easily drained away with muddy water because a part where the iron particles tend to be accumulated along a magnetic flux functions as a groove-like path. Additionally, accumulated iron particles remain inside the groove unit 7 that is concave shaped. Accordingly, prevention of damage to the sensor head unit 6 is achieved.

    摘要： A pedal supporting structure for a vehicle includes a pedal bracket secured to a dash board, a pedal shaft for swingably supporting a pedal arm, a pin member for mounting the pedal shaft on the pedal bracket and a separation member secured to a support beam. An arm section of the separation member has a guide slot capable of a relative displacement of a pin member inserted to the pedal shaft and contacting the slanted surface. The arm section of the separation member has a slanted surface at the middle thereof. When an external force larger than a specified value is applied to a front part of the vehicle, due to the relative displacement between the pedal bracket and the separation member, the pin member comes out of the pedal shaft and as a result the pedal arm is separated from the pedal shaft.
