Abstract: The present invention provides a current detection device comprising a core skirt for accommodating therein a core, a core stopper for fixing the core and a magnetic-sensitive element mounted on a substrate, the substrate and the core skirt having engaging portions for locating the magnetic-sensitive element, respectively, provided thereon, and further provides a core for detection of a magnetic flux.

Abstract: A composite type light sensor compriser of a sensor portion molded into a light-transmitting resin together with light receiving elements and a case portion mounted with light receiving means such as a lens for receiving the sensor portion.

Abstract: A light control apparatus for a vehicle is integrated with headlamp driving relays, a light sensor, a lighting switch which selects a manual mode or an automatic mode, and a control unit which controls the relays in accordance with the light sensor output when the lighting switch selects the automatic mode and turns on or off the headlamps. Two power source systems and two headlamp driving systems are provided. The signal level of a given terminal of the control unit is detected and is input to the microcomputer of the control unit. The microcomputer judges whether or not trouble has occurred by detecting a level difference. An alarm indication is given by a lamp or a buzzer if trouble is detected.

Abstract: Apparatus for opening and closing a retractable head lamp which includes a hand operated switch for effecting lighting and unlighting of the head lamp and initiating opening and closing movements of the head lamp, motor for driving a retracting mechanism for opening and closing the head lamp and a detector for detecting a desired position (opened and/or closed) of the head lamp and for selectively stopping energization of the motor when the head lamp reaches a desired position. A control means is connected between the hand switch and the detecting means and is responsive to operation of the hand switch from a lighting position substantially instantaneously to an unlighting position to prevent energization of the motor, thereby preventing closing of the previously opened head lamp.

Abstract: A fluid control circuit for a radio controlled vehicle for operating an engine, transmission, steering, movable elements of earth-moving machines and braking device of the vehicle by means of radio control. The control circuit has plural shuttle valves interposed between brake cylinders and solenoid operated valves for controlling the brake cylinders. A circuit changing valve is interposed between a conduit communicating with the source of fluid under pressure and conduits communicating with operating cylinders for the engine, transmission, steering, earth-moving machines and braking devices through respective solenoid valves and the shuttle valves. Circuit changing valve is manually operable for selectively feeding fluid in pressure from the source thereof to either conduit communicating with the respective operating cylinders. Thus, the remote control of the vehicle can be simply changed to a manual one or vice versa by a single operation.
