Abstract: A separate emitter follower type bias circuit is connected to each base electrode of a transistorized differential amplifier which handles unbalanced input signals. A series circuit of resistors is employed for supplying a suitable bias voltage common to both emitter follower type bias circuits.

Abstract: An antenna system is disclosed which has a loop antenna divided into n conductive members at n pairs of divisional points where n is a positive integer not smaller than 2, n feeders connected to the n pairs of divisional points respectively, a signal feeding point, and at least one impedance element. In this case, electrical switching circuits are connected between the n feeders and the impedance element, and an electrical control circuit is connected to the electrical switching circuits for selectively connecting the feeding point to one of the n feeders and at the same time for selectively connecting the impedance element to another of the n feeders, so that the directivity characteristic of the antenna system is variable controlled.

Abstract: An undesired signal canceller for a composite amplitude modulated signal including an undesired signal delayed by a time ?o from a desired signal. The composite signal is supplied to a detector circuit. A carrier signal of the same frequency as that of the amplitude modulated carrier and delayed in phase by the time ?o is produced. This carrier signal is amplitude modulated with a signal formed by delaying the output signal from the detector circuit by the time ?o and the amplitude modulated carrier signal is combined with the composite amplitude modulated signal to cancel the undesired signal therefrom.

Abstract: A variable reactance circuit is composed of a differential amplifier having first and second emitter-coupled transistors, a reactance element, such as a capacitor, connected between the collector and base electrodes of the first transistor, and a control signal source connected to the emitter electrodes of the transistors by which the input impedance of the first transistor is effective as a variable reactance which is changed in accordance with the level of the control signal. Such variable reactance circuit may be used with an oscillator or resonance circuit to constitute a frequency modulator controlled by the control signal source.

Abstract: An undesired signal canceller for a composite amplitude modulated signal including an undesired signal delayed by a time tau o from a desired signal. The composite signal is supplied to a detector circuit. A carrier signal of the same frequency as that of the amplitude modulated carrier and delayed in phase by the time tau o is produced. This carrier signal is amplitude modulated with a signal formed by delaying the output signal from the detector circuit by the time tau o, and the amplitude modulated carrier signal is combined with the composite amplitude modulated signal to cancel the undesired signal therefrom.

Abstract: 1461443 Bistable circuits SONY CORP 1 Feb 1974 04901/74 Heading H3T A bistable multivibrator comprises first and second bistable stages 1, 2 intercoupled via a steering gate circuit 3; first and second clock input circuits 16, 17 for isolating nodes 23, 24 so as to enable the bistable stage 1 and the steering gate 3 to be actuated independently so as to assure correct triggering by a clock signal. Circuit 17 may preferably be biased to turn on and turn off ahead of circuit 16. The clock pulses serve to periodically enable and disable the master bistable stage 1 and the steering gate 3. In the turned off state, transistors 13, 14 are effectively equivalent to base collector diodes with a threshold voltage Vbc. The conduction states of the transistors 5, 6 in the master bistable 1 and of transistors 7, 8 in the slave bistable 2 are periodically altered in dependence of the base potentials existing of steering gate transistors 14, 13.
