Twt circuit simplifies microwave relay.
Sawtooth-modulated TWT circuit acting as frequency converter and amplifier in microwave relay system
Circuit exhibits power efficiency greater than 75 percent
Variable duty cycle pulser increases circuit power efficiency by more than 75 percent when operating solenoid valves. The pulser provides a low-level holding current after a high-level current has actuated the solenoid valves.
Ring counter circuit switches multiphase motor direction of rotation
Solid state three-phase counter circuit reverses the direction of rotation of a multiphase motor without changing the phase wiring of the supply current source.
Improved chopper circuit uses parallel transistors
Parallel transistor chopper circuit operates with one transistor in the forward mode and the other in the inverse mode. By using this method, it acts as a single, symmetrical, bidirectional transistor, and reduces and stabilizes the offset voltage.
Exclusive-or logic circuit has useful properties
Single, simple exclusive-or logic connective eliminates excessive hardware and the number of interconnections between logic modules. This circuit performs the necessary switching for the exclusive-or operation and amplifies, restores, and inverts the signal.
Simple circuit provides reliable multiple signal average and reject capability
Summation average and reject circuit based on diode clamping allows detection of individual functional deviations in a multiple signal system without shutting down the entire system.
Transistor circuit increases range of logarithmic current amplifier
Circuit increases the range of a logarithmic current amplifier by combining a commercially available amplifier with a silicon epitaxial transistor. A temperature compensating network is provided for the transistor.
Electronic bidirectional valve circuit prevents crossover distortion and threshold effect
Four-terminal network forms a bidirectional valve which will switch or alternate an ac signal without crossover distortion or threshold effect. In this network, an isolated control signal is sufficient for circuit turn-on.
Control circuit maintains unity power factor of reactive load
Circuit including feedback control elements automatically corrects the power factor of a reactive load. It maintains power supply efficiency where negative load reactance changes and varies by providing corrective error signals to the control windings of a power supply transformer.
Point-source light sensor circuit is insensitive to background light
