A device for rapidly moving mechanically actuated devices, such as switches and valves with the capability of sub-millisecond response times being achievable with moving masses exceeding one kilogram. Response times approaching that of explosively actuated devices are obtained while retaining the repetitive cycling capability of non-explosively operated devices. Electrical energy stored in a capacitor pulses through electrodes and closed and open ends of a capillary tube to rapidly heat a gas and raise its pressure to a thousand atmospheres or more. The high pressure gas acts on a piston, accelerating it for a short distance before the pressure is vented around the piston to quickly reduce the drive force. The moving piston is brought to a stop by a hydraulic damping device. A reset device resets the piston, the capillary is refilled with working gas, and the capacitor is charged fro the next operation. |

A circuit breaking control unit receives an impact detection signal that is outputted from outside when an impact such as a crash of a motor vehicle has been detected, and generates and applies a circuit breaking control signal based on the impact detection signal. A circuit breaking unit forcibly interrupts a power supply path and stops the supply of power to a load. Therefore, the supply of power can be stopped immediately at the time the impact has been detected. In addition, a second load is a minimum electric system that is essential to cause the motor vehicle to travel. Therefore, even if the supply of power to the load is interrupted, the motor vehicle can be caused to travel. Hence, even at the time of an accident or the like, the motor vehicle can be moved to the edge of a road or the like with ease. |
