A voltage across both ends of the voltage dividing resistance 8 is inputted to the comparator 10, and its output is connected to the light emitting element 12 via a transistor 11. When a residual charge remains in the DC capacitor element 6, the output of the comparator 10 is set at an H-level, the transistor 11 is set to continuity, and the light emitting element 12 emits light. When an electric charge does not remain in the DC capacitor element 6, the output of the comparator 10 is set at an L-level, the transistor 11 is turned off, and the light emitting element 12 does not emit light.  Consequently, when a capacitor is approached by confirming that the light emitting element 12 is turned off, it is possible to prevent an electric shock accident.

Abstract: PROBLEM TO BE SOLVED: To obtain sufficient impact absorption effects even if a small object collides against a car over a wide area by plastically deforming at least a surface layer side of a double structural body into a swelling shape when fluid pressure is filled therein. SOLUTION: When an automobile which is running collides against a pedestrian, a pedestrian collision detection switch 7 is closed, an ignition current flows in an inflator 5, and the resultant gas blows into the inside of an engine hood 1 having a double structure through an opening 4. Then, the whole surface of a surface layer material 2 of the engine hood 1 swells upward due to the pressure as shown by a two-dot chain line and is plastically deformed into the swelling shape. Consequently, a space 8 generated between the surface layer material 2 and a rear layer material 3 becomes an impact absorption stroke. When the head of the pedestrian who falls down because his leg is swept out from under him by a front bumper 6 collides against the engine hood 1, the surface layer material 2 catches the pedestrian's head and caves in.
