    摘要: A radio antenna device having a gain compensating circuit and an antenna wire rigidly secured to the rear window of a motor vehicle, coupled with a moisture preventive heat wire. The antenna wire is secured to the rear window of the motor vehicle so as to reduce the noise in the received radio waves, which results from electrical noise from the vehicle engine, electric generator and electric motor. The rear window also serves as a convenient antenna space. A gain compensating circuit is provided for compensating for the reduction in the level of the received radio wave, which reduction is caused by the shielding action of the moisture preventive heat wire secured to the rear window and the portion of the body of the vehicle, which extends along the periphery of a rear window.

    摘要: A drive control apparatus controls a drive of an inductive load having a current flowing therethrough. The drive control apparatus includes a drive control device for controlling a variation of the current flowing through the inductive load within a certain period by Pulse Width Modulation control so as to come close to a reference current value, and a reference value control device for controlling a fluctuation period of the reference current value and making the fluctuation period of the reference current value longer than that of the current flowing through the inductive load by the Pulse Width Modulation control.

    摘要: In an ignition semiconductor device, a self-shut down circuit forcibly turns off an IGBT when an input signal is continuously applied. The self-shut down circuit is formed of a main-current gradual-reduction circuit having a timer circuit, a capacitor, a resistor, and an FET. When the timer circuit, which is actuated when the input signal is input, counts out, the FET is turned on to cause a capacitor, which is connected parallel to a resistor for producing a reference voltage for a current-limiting circuit, to discharge slowly through the resistor, thereby gradually reducing the reference voltage. Correspondingly, the current-limiting circuit reduces the main current to turn off the IGBT. The slow turn-off operation of the IGBT prevents a high voltage from being generated in the ignition coil. Accordingly, an unwanted high voltage is prevented from being generated in the secondary winding of an ignition coil when an output-stage element is forcibly turned off following the continuous application of an input signal.

    摘要: A slide switch opening and closing a circuit for supplies electricity to a load by making and breaking contact between a movable contact and a stationary contact. The stationary contact is integrally formed with an arc generating portion for generating an arc when the circuit is opened or closed. The arc generating portion protrudes in the direction of movement of the movable contact and has a width which gradually decreases from its base portion towards its tip portion. The slide switch is capable of preventing the arc generating portion and the movable contact from having a groove due to wear.

    摘要: A sliding switch having a tandem-type contact structure in which a first and a second insulation portion are disposed in a first and a second negative fixed contact, respectively, of a first and a second group of fixed contacts. When a first and a second movable contact slide between a neutral position and a first operating position, an arc is produced between the first movable contact and the first negative fixed contact in which the first insulation portion is disposed. When the first and the second movable contact slide between the neutral position and a second operating position, an arc is produced between the second movable contact and the second negative fixed contact in which the second insulation portion is disposed. A decline in the insulation performance between the fixed contacts of different polarities is prevented.
