    • A compact gas-expansion-type power source breaker by which a power supply circuit can be forcedly and surely isolated only in case of abnormalities such as short-circuiting of a wire harness or collision of road vehicles is provided. A lock 18 for constraining movement of a shaft 16 is set in a locked state by means of pushing force for constraining the movement of the shaft 16 forcedly provided by a reset spring 19 on one hand, and is connected via a lock operation plate 20 with a piston 21 for forcedly providing a reverse pushing force beyond the pushing force of the reset spring 19 sublimation of a gaseous actuating reagent 23 contained in a igniter 22 on the other hand. Once a circuit-cut signal is applied to the igniter 22, the gas actuating reagent 23 will vaporize or sublimate, and the piston 21 will operate to make the lock 18 released forcedly from the shaft 16, only when the piston 21 is provided with the reverse pushing force beyond the pushing force of the reset spring 19 by means of gases generated by the vaporization or sublimation of the gaseous actuating reagent 23. Consequently, it can be avoided that the shaft may move slidingly due to any other causes such as impulse, vibration than the vaporization or sublimation of the gaseous actuating reagent 23, resulting in the isolation of the power supply circuit.
    • 一种致密的气体膨胀型电源断路器,其中电源电路只有在诸如线束短路或道路车辆碰撞等异常的情况下才能被强制且可靠地隔离。 用于限制轴16的运动的锁18通过用于限制由复位弹簧19强制提供的轴16的运动的推动力被一体地设置在锁定状态,并通过锁定操作板20与 活塞21,用于强制地提供超过复位弹簧19的推力的反推力,另一方面,该活塞21包含在点火器22中的气态致动试剂23的升华。 一旦将电路切断信号施加到点火器22,气体致动试剂23将蒸发或升华,并且活塞21将操作以使锁18被强制地从轴16释放,只有当活塞21设置有 通过气态致动试剂23的蒸发或升华产生的气体,反向推动力超过复位弹簧19的推力。因此,可以避免轴由于任何其它原因(例如脉冲, 振动比气态致动试剂23的蒸发或升华,导致电源电路的隔离。

    • A local air cleaning apparatus (1) is provided with a push hood (2) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a guide (3) provided on a side of the push hood (2) having the air flow opening face (23), the guide (3) extending from the side thereof having the air flow opening face (23) toward a downstream side of the uniform air flow to form an opening face (31) at a downstream end portion thereof. The push hood (2) is arranged such that the uniform air flow blown out from the air flow opening face (23) passes through the inside of the guide (3) and then collides with an air collision face (W) on a downstream side of the opening face (31). The opening face (31) of the guide (3) is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face (3) and the air collision face (W). The cleaned uniform air flow blown out from the air flow opening face (23) collides with the air collision face (W) and flows out of the opening region, thereby allowing the inside of the guide (3) and the inside of the open region to have higher cleanliness than other regions.
