Abstract: A connector device for coupling a wiper arm and a wiper blade includes a coupling body, a first support portion provided on an upper surface of the coupling body and extending from the coupling body in a form of a cantilever and for applying an elastic restoration force to the wiper arm, a second support portion provided for supporting the wiper arm in a thicknesswise direction of the wiper arm to prevent the wiper arm from moving in the thicknesswise direction, and a third support portion for preventing the wiper arm from moving in a lengthwise direction of the wiper arm, wherein the second support portion is in a form of a hole with closed upper and lower sides and open front and rear sides.

Abstract: A switching device is provided that includes a switching mechanism unit and a switch drive control circuit. In the switching device, an operating member is maintained in an ON position by the sucking force of a permanent magnet and a yoke, despite the pushing force of a biasing unit, when the permanent magnet is in an ON position. The yoke is magnetized in such a manner as to reduce the magnetic force of the permanent magnet, when a coil wound around the yoke is energized by the switch drive control unit. The operating member and a switching member are moved from the ON position to the OFF position by virtue of the pushing force of the biasing unit, thereby shutting a feed line.

Abstract: Disclosed is an earth leakage detection device, which comprises a printed-circuit board incorporating an earth-leakage-detection control circuit, a reset function-equipped switch mounted on the side of one of opposite surfaces of the printed-circuit board, an earth-leakage-detecting current transformer mounted on the side of the other surface of the printed-circuit board, an externally connecting terminal for introducing and outputting an electrical power, and an electrical wire member arranged to penetrate through the earth-leakage-detecting current transformer and connected relative to the externally connecting terminal. In this earth leakage detection device, the reset function-equipped switch is connected to the earth-leakage-detection control circuit with the interposition of the externally connecting terminal therebetween.

Abstract: A magnetically sensitive element is integrated with an operation controlling element by film-forming process or bonding of film-shaped bodies. The operation controlling element is formed as a single layer or multilayers and contains a permanent magnet or a magnetic circuit forming member. A pickup coil may also be integrated thereto. The magnetically sensitive element is a magnetic element in which a giant Barkhausen jump phenomenon appears.
