    摘要： A power control apparatus includes an input terminal and an output terminal for an AC signal; a DC removing capacitor connected between the input terminal and the output terminal; and a variable capacitor that is connected between the input terminal and the output terminal and whose capacitance can be changed by a control signal. One of a current and a voltage of the AC signal is controlled by changing the capacitance of the variable capacitor using the control signal, and dielectrics that form a serially connected row of capacitors composed of the DC removing capacitor and the variable capacitor are configured so as to be integrally laminated, and the control signal is applied across a dielectric that forms the variable capacitor and the AC signal is applied across the dielectrics that form the row of capacitors.

    摘要： A safety circuit for an electrical iron is provided comprising a double through position sensitive switch having a common contact that is connectable to connect a horizontal position sensing contact and a vertical position sensing contact. When the iron is in use, the common contact will continually shift its contact between the two position sensing contacts, which enables the coupling of power to the heating circuit of the iron. When the iron is placed either horizontally or vertically, a delay timer of a control unit will start to count passage of time. When a preset time has elapsed, the control unit will deactivate the coupling of power to the iron's heating circuit. However, during this period when time is being counted or subsequent to the deactivation of power, if use of the iron is resumed, the control unit delay timer will start to count from the very beginning and the power will be activated again.

    摘要： In a method and apparatus to regulate the illumination range of a motor vehicle in which, at a position on a front axle and at a position on a rear axle, signals are measured which are dependent upon the relative positions of a motor-vehicle body to the front axle and the rear axle, with a difference formation between the signal from the front axle and that of the rear axle being accomplished with a resulting difference signal, as a nominal-value signal, being filtered to a first average-value formation. The time for the first average-value formation is determined by a first filter (F1) time constant with positions of adjusting elements being regulated when the first filtered nominal-value deviates from a predetermined, or set, value. Simultaneously with the first average-value formation, a second average-value formation of the nominal-value signal with a second small, or short, filter (F2) time constant, and a third average-value formation of the nominal-value signal with a third, long, filter (F3) time constant takes place. The second, filtered, nominal-value signal is compared with the third, filtered, nominal-value signal, and upon the existence of a difference there between, a regulation from the first, filtered, nominal-value signal is switched over to the third, filtered, nominal-value signal and upon a termination of the difference is again switched over from the third, filtered, nominal-value signal to the first, filtered, nominal-value signal.

    摘要： A safety device for a tool powered by an electric motor. It has a main switch, electronic controls, and a tachometer-generator. In order to provide a device for switching off a motor as a function of motor speed that is simple and economical and that will retain the same nominal switch-off value for the total life of the device, a relay is wired in parallel with the motor and controls the supply of power to the motor through a relay contact.

    摘要： A control network that may be used to automatically turn off the drive motor and/or the mechanical drive of a tape deck when the tape has reached the end of its travel, but which also has many other uses, includes a capacitor that is connected to be charged from a source of D.C. potential. A circuit for discharging this capacitor includes a current responsive control device and a controlled discharge device having anode, cathode and control electrodes. A second capacitor connected to be charged from a source of D.C. potential is connected in circuit with the control electrode to control the operation of the controlled discharge device responsive to the charge on the second capacitor. Means are provided for discharging the second capacitor during normal operation of the tape deck or other device at a repetition rate such that insufficient charge builds up on the second capacitor to trigger the controlled discharge device.
