摘要： A circuit breaker includes a current path for first and second contacts connected in series in an insulative container. When an overcurrent occurs by over load, the second contact is opened based on a command from a time delay trip portion of an overcurrent trip device. When a short-circuit current occurs, the first and second contacts are opened based on a command from an instantaneous trip portion of the overcurrent trip device. Since the first and second contacts are contained in a common container, the wiring works between the first contact and the second contact is unnecessary. Since the first and second contacts are opened in the instantaneous trip, interruption of a high short-circuit current is facilitated.
摘要翻译：断路器包括用于在绝缘容器中串联连接的第一和第二触头的电流路径。当通过过载发生过电流时，基于来自过电流跳闸装置的时间延迟跳闸部分的命令来打开第二触点。当发生短路电流时，基于来自过电流跳闸装置的瞬时跳闸部分的命令来打开第一和第二触点。由于第一和第二触头容纳在公共容器中，所以不需要在第一触点和第二触点之间工作的布线。由于第一和第二触点在瞬时跳闸中被打开，因此便于中断高的短路电流。

摘要： The present invention is a piezoelectric actuator for stabilizing the driving of a small-sized chopper, thereby enhancing reliability of a pyroelectric type infrared ray sensor, wherein actuator is a unimorph type actuator having a piezoelectric element adhered to a shim. The shim and a displacement magnifying part are bound in a U-form. The resonance frequencies due to the vibrations of the unimorph type actuator and the displacement magifying part are brought close to each other wherein the chopper is driven at an intermediate frequency. As a result, a stable displacement magnifying effect is obtained at the front end of the displacement magnifying part.

摘要： A pyroelectric infrared radiation detector for detecting the intensity of infrared radiation with a pyroelectric element. The pyroelectric infrared radiation detector comprises a substrate made of a single crystal material and an infrared radiation detecting structure which comprises a first electrode disposed on the substrate, a pyroelectric thin film disposed on the first electrode, and a second electrode disposed on the pyroelectric thin film for absorption of infrared radiation. The substrate has a recess provided in the upper surface thereof where the infrared radiation detecting structure is seated. A method of producing the pyroelectric infrared radiation detector comprises a first step of forming a first electrode on one surface of a substrate, a second step of forming a pyroelectric thin film on the first electrode, a third step of forming a second electrode on the pyroelectric thin film, a fourth step of providing etching apertures in the first electrode which is open to the substrate, and a fifth step of providing by wet etching process a recess(es) in the surface of the substrate where the first electrode is seated.
