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: The gas rate sensor in the present invention is provided with a holder assembly having a metallic holding portion for holding flow sensors and a cylindrical casing containing the holder assembly and heater wires which are wound around the outside thereof. The outer periphery of the holding portion is provided with a plural number of projections which are brought into compressive contact with the inner periphery of the casing for enabling pressing of the holder assembly into the casing. A temperature detection element is disposed in a gas flow passage between the holder assembly and the casing for performing energizing control of the heater wires.

Abstract: A method of manufacturing a fluidic angular rate sensor of the type wherein fine wires, such as tungsten wires, are mounted in tension over the heads of two pairs of spaced apart metal supports which are mounted on a ceramic disc having fluid passage apertures therein, comprising plating gold on the wires; fixedly mounting the wires between the spread apart metal supports by means of thermocompression bonding or the like; and heating the mounted gold plated wires in a predetermined atmosphere for removing the plated gold from the wires and to recrystallize the wires.

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: An automatic light control apparatus for a vehicle comprises an external light detector for selectively turning on and turning off at least one of tail lamps, side marker lamps and head lamps of a vehicle in accordance with the detected external light. A further detector is provided for detecting the ON period of an illuminating light having a fluctuating light value (for example generated by an A.C. voltage source), and the lamps are further controlled in accordance with the detected ON period of the fluctuating light value in conjunction with the signals generated by the external light detector, for controlling the illumination of the lamps of the vehicle. A further detector may be provided for detecting an abrupt change in the illumination level, and for controlling the vehicle lamps further in accordance with the detected abrupt change.

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: An automatically returning apparatus for turn signal lamp switch includes a semiconductor switching circuit for detecting a certain running distance of vehicle after the throwing of the turn signal lamp switch, a driving circuit for energizing a solenoid provided to cause the turn signal lamp switch to return to its non-operating position and a circuit for maintaining continuous operation of the solenoid for a given time after the turn signal lamp switch starts its opening or returning operation.

Abstract: A switch mechanism for a turn signal having a transmitting means which is interposed between a stopper means for holding a moving contact piece to a position moved by an operating knob and means for releasing a holding force of the stopper means. The release means actuates the transmitting means which in turn operates on the stopper means to permit the turn signal to be reset to its initial inactive condition.
