Title: Power amplifier
Inventor: HORI FUMIO
IPC: H03F3/21
Filed: 1982-02-12
Abstract: PURPOSE:To attain the operation with high performance, by changing a bias in response to an input voltage or an output voltage, performing the operation of high efficiency and low loss at low frequencies and eliminating pulsive distortion through blunting the change in a collector voltage at high frequencies. CONSTITUTION:When an input signal frequency is low, a differentiation output through a diode D4 and a Capacitor C1 is small and only an output detected from a diode D3 is applied to the base of the 2nd transistor (TR)Q2. Thus, the rate of change in a collector voltage Vc is small and the generation of a pulsive distortion is almost out of a problem. The higher the input signal frequency is, the larger the collector-to-emitter voltage of the 1st TRQ1 becomes, and since the capacitance between the collector and the base of the 1st TRQ1 is small even if the collector voltage Vc is changed rapidly, no pulsive distortion is generated in an output voltage e0. No pulsive distortion is generated even at a negative half cycle of the input signal with the similar operation.

Title: Receiver for hyperbolic navigation
Inventor: TSUKADA KAZUO
IPC: G01S5/10
Filed: 1979-02-26
Abstract: PURPOSE:To economize a receiver for a hyperbolic navigation by detecting the phase difference in a digital processor to integrate the circuit of the receiver and reducing the number of expensive voltage controlled crystal oscillator to one. CONSTITUTION:A voltage controlled crystal oscillator 122 is controlled by comparing in phase a master station intermediate frequency signal with the frequency divided output signal of the output obtained by mixing the outputs of a local oscillator 127 and the oscillator 122, and thus synchronized in phase with the received signal. The output of the oscillator 127 is applied through a synthesizer 128 and second frequency divider chain 148 having substantially equal frequency division to both inputs of a phase difference detector 118 to cancel the variation in the oscillated frequency of the oscillator 127 by the phase difference detector. Thus, the intermediate frequency can be lowered to reduce the operating frequency of phase tracking filters 102-104 and phase difference measuring circuits 108-110 all to less than several MHz. Thus, they can be readily integrated.
