    Abstract: A control electrode overlies one of the base regions of the thyristor, a dielectric layer being disposed therebetween. To minimize the potential stress applied across the dielectric layer, the control electrode overlies less than the entire width of the depletion layer associated with the thyristor forward direction, voltage blocking PN junction.

    Abstract: A voltage comparator compares the voltage across a capacitor which is being charged with a reference voltage of a first value. When the voltage across the capacitor becomes equal to this first value, the comparator causes the reference voltage to switch to a second lower value and, a short time later, the capacitor is caused to switch from a charging to a discharging condition. When the two voltages again become equal, the process is reversed. In a preferred circuit, the means employed to delay the switching of the capacitor condition comprises a threshold detector connected to receive the reference voltage applied to the comparator and having a threshold intermediate the first and second reference voltage values.

    Abstract: The speed of a motor is controlled by utilizing an error signal from a phase comparator as the motor energizing source. The phase comparator error signal is a result of a phase comparison between a motor related signal and a reference signal having a phase which varies in a predetermined manner as a function of time.

    Abstract: An adjustable polarization system is provided by the combination of an adjustable power divider and an orthogonal coupler. One terminal of the power divider is coupled to one terminal of the orthogonal coupler through a 90* polarization rotator, the second terminal of the power divider being coupled to a second terminal of the orthogonal coupler. By an adjustment in the power divider, the percentage of power to the input terminals of the orthogonal coupler are altered and consequently the polarization is adjusted.

    Abstract: A tape cartridge changer includes a plurality of tape cartridge receptacles which are each adapted to receive a tape cartridge and a movable structure which supports a portion of the changer playing mechanism. A movable mechanical stop is positioned adjacent each of the receptacles to block an inserted tape cartridge from being positioned in the path of travel of the movable structure. The movable structure as it moves toward each cartridge receptacle engages and moves the mechanical stop adjacent the cartridge receptacle away from its blocking position. This permits a tape cartridge in the cartridge receptacle to be brought into operative engagement with the portion of the tape changer playing mechanism supported by the movable structure. Detector means at each of the cartridge receptacles sense the presence or absence of a tape cartridge in the receptacle. As the movable structure moves between the different cartridge receptacles, a switch mechanism mounted on the movable structure is actuated by the detector means when a cartridge is sensed as being present in the receptacle. The switch mechanism is operable when actuated to stop the movable structure at a predetermined point for playing a cartridge in the receptacle.

    Abstract: A metal rod is inserted through the left and right capillary tubes of a gas discharge device. One end of a coaxial bulb joining one capillary tube is heated until the glass thereof is softened. Then, the metal rod is rotated within the two capillary tubes until the bores thereof are axially aligned. Then, the softened end of the bulb is allowed to cool to fix the aligned capillary tubes. Then, the metal rod is removed from the discharge device.
