摘要： A switching controller for circuit breaker in which a switching control arithmetic operation unit performs arithmetic operations to determine for each circuit breaker a synchronous delay count value which is sent to each switching command control unit of the corresponding circuit breaker, which upon receiving a switching command signal from a superordinate device, counts the synchronous delay count value D, to turn on a semiconductor switch of the switching command output unit after counting completes. The switching command signal (circuit breaker drive current) is output after the synchronous switching control to the circuit breaker drive coil of the circuit breaker. The switching controller can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.

摘要： The MPU for switching control arithmetic operation 210 in the switching control arithmetic operation unit 200 performs arithmetic operations to determine a predetermined delay time (synchronous delay count value D) for each circuit breaker 1100. The synchronous delay count value is sent to each switching command control unit 400 of the corresponding circuit breaker. The hardware counter 20 of the switching command output control unit 450, for the switching command signal received from the superordinate device 2000, counts the synchronous delay count value D, which is the delay time. When the semiconductor switch of the switching command output unit 10 turns ON after counting completes, the switching command signal (circuit breaker drive current) after the synchronous switching control is output to the circuit breaker drive coil 1110 of the circuit breaker 1100. A switching controller for circuit breaker and a switching control system for circuit breaker are provided, which can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.

摘要： A wiper device is located between a vehicle rear door and a rear window, which is opened independently from the door. An actuator having an output shaft is fixed to the rear door. A pivot disk is fixed to the output shaft. The pivot disk has a coupler hole. The actuator pivots the coupler hole in a predetermined angle range. A pivot shaft having a wiper arm is supported by the rear window glass. A crank lever having a coupler pin is fixed to the pivot shaft. When the rear window glass is closed with the coupler pin outside of the movement range of the coupler hole, engagement between the coupler pin and the coupler hole moves the coupler pin to the angle range of the coupler hole. Accordingly, the crank lever is positively coupled to the pivot disk by a simple structure.

摘要： A water-in-oil emulsion explosive characterized by containing an ethylene vinyl acetate copolymer. It has excellent long-term stability. Even when stored under a load for as long as about one year, the explosive is less apt to suffer a decrease in explosive performance and coagulates only slightly in such a degree that it comes to have weakly coherent partial coagulates which can be easily disaggregated. Even after long-term storage, charging with the explosive can be easily conducted with a charger. Since the explosive has excellent water resistance, it is suitable also for blasting in a water hole.

摘要： The wiper pivot unit for smoothly absorbing a load applied from the outside of a vehicle. The wiper pivot (1) has a pivot shaft (3), a pivot holder (4) and a toothed washer (5). The pivot shaft has a small-diameter section (31) and a large-diameter section (32). The toothed washer is fitted on the large-diameter section to constrict it with a predetermined force. The toothed washer slips off the large-diameter section when a load of a predetermined value or more acts upon the pivot shaft. When the toothed washer is shifted to the small-diameter section, the pivot shaft descends smoothly along the pivot holder.

摘要： Test pattern data is recorded on a track of the optical disc, and the other pattern data is recorded on the neighboring track. A focus bias value providing the minimum jitter amount when the test pattern data is reproduced with varying the focus bias, is obtained. Just focusing condition is attained by the focus servo using the focus bias. When the test pattern data is reproduced, the data of these neighboring track is also reproduced simultaneously because the pattern data of the type different from the test pattern data is also recorded on the neighboring track. Particularly, under the defocusing condition, crosstalk amount becomes larger because the beam shape is distorted. With reference to jitter amount, such a mistake that the defocusing condition is erroneously determined as the just focusing condition can be eliminated. That is, the focus servo signal providing the accurate just focusing condition can be obtained.
摘要翻译： 测试图案数据被记录在光盘的轨道上，而另一个图案数据被记录在相邻的轨道上。 获得当通过改变聚焦偏压再现测试图案数据时提供最小抖动量的聚焦偏置值。 通过使用聚焦偏置的聚焦伺服来达到聚焦条件。 当再现测试图案数据时，由于与测试图案数据不同的类型的图案数据也被记录在相邻的轨道上，所以这些相邻轨迹的数据也被同时再现。 特别地，在散焦条件下，由于光束形状失真，串扰量变大。 关于抖动量，可以消除将散焦条件错误地确定为刚刚聚焦条件的错误。 也就是说，可以获得提供准确的聚焦条件的聚焦伺服信号。
