摘要： An input overcurent suppression circuit is used for a DC-DC converter in uninterruptible power supply source and includes a plurality of DC-DC converters, an AC-DC converter and a detecting means for detecting an input current to the DC-DC converters. In the plural DC-DC converters, a parallel circuit constituted by a resistor element and a switching element is connected in series with an input circuit to break the circuit in response to an overcurrent or over heating. When the power source circuit is closed, a surge current-preventing circuit prevents the surge current by turning a switching element off for a predetermined period of time. The AC-DC converter feeds current to at least two or more DC-DC converters among the plurality of DC-DC converters. When the detecting means has detected an overcurrent, the switching element is turned off to turn off the resistor element connected in parallel with the switching element, to thereby suppress the overcurrent flowing into the AC-DC converter.
摘要翻译：输入过压抑制电路用于不间断电源中的DC-DC转换器，并且包括多个DC-DC转换器，AC-DC转换器和用于检测对DC-DC转换器的输入电流的检测装置。在多个DC-DC转换器中，由电阻元件和开关元件构成的并联电路与输入电路串联连接，以响应于过电流或过热而断开电路。当电源电路闭合时，浪涌电流防止电路通过使开关元件断开预定的时间来防止浪涌电流。 AC-DC转换器将电流馈送到多个DC-DC转换器中的至少两个或更多个DC-DC转换器。当检测装置检测到过电流时，开关元件被断开以关闭与开关元件并联连接的电阻元件，从而抑制流入AC-DC转换器的过电流。

摘要： Both ends of a circling scroll are supported by a pin crank and the eccentric shaft of the circling scroll, thus assuring a stable circling or oscillating motion of the scroll. This in turn allows the scroll tooth length to be elongated, leading to an increase in the capacity of the fluid machine. Because the eccentric shaft and the pin crank are fitted into the center boss, the pin crank can work as a shaft that supports the left end of the circling scroll. The provision of the boss allows a radial load acting on the scroll tooth to be borne at the load position, thus shortening the shaft and reducing the bearing. Because the pin crank can be mounted to the boss, a two-block parallel arrangement and two-stage arrangement can be implemented easily. Further, the construction in which the pin crank is used as a left-end supporting bearing contributes to reducing the manufacturing cost of the apparatus.
摘要翻译：旋转涡卷的两端由一个针脚和圆盘形的涡卷的偏心轴支撑，从而确保了涡卷的稳定的盘旋或摆动运动。这又允许涡旋齿长度增长，导致流体机器的容量增加。由于偏心轴和销脚曲柄被装配到中心凸台中，所以曲柄可以作为支撑盘旋的左端的轴工作。凸台的设置允许作用在涡旋齿上的径向载荷承载在载荷位置，从而缩短轴并减小轴承。由于针脚可以安装到凸台上，所以可以容易地实现两块平行布置和两级布置。此外，将销曲柄用作左端支撑轴承的结构有助于降低装置的制造成本。

摘要： A jig for measuring the characteristics of various semiconductors has three main elements including a first circuit board to be connected to a tester for measuring the characteristics of the semiconductor, a second circuit board to be connected to the semiconductor and an intermediate board located between the first and second circuit boards. The first and second circuit boards are electrically connected together through springy pins. These pins, secured to the first circuit board, extend through the intermediate board via through holes to contact with terminals located in the second circuit board. When measuring the characteristics of various semiconductors it is possible to use the jig by replacing only the second circuit board with a board adapted to the particular semiconductor being measured without replacing the other elements of the jig.
