Patent JP-S58150303-A (JP)
Title: Power amplifier
Inventor: ISHIGURO HIDEO
IPC: H03F1/02
Filed: 1982-03-03
Abstract: PURPOSE:To ensure high efficiency of a power amplifier without using any special additional power supply, by superposing the AC voltage of an output on the DC power supply voltage and impressing this superposed voltage as a power supply of a driving amplifier. CONSTITUTION:When windings 11 and 12 are connected with polarities as shown in the diagram, an AC waveform proportional to the output voltage e0 of a power amplifier is superposed on the power supply voltages +V and -V of a driving amplifier 1. As a result, a desired amount of power is obtained at a desired time point for the amplifier 1 since the voltage +V rises up when the voltage e0 increases, and the waste of power is avoided. In such a way, the AC voltage of an output is superposed on the DC power supply voltage to be impressed as a power supply of the amplifier 1, and the power supply voltage is raised when necessary. As a result, a driving amplitude larger than the DC power supply voltage can be obtained. Thus the efficiency can be increased for a power amplifier without using any additional power supply.

Title: Crystal oscillator
Inventor: ONOUE MORIO
IPC: H03H9/215
Filed: 1980-03-17
Abstract: PURPOSE:To ensure the mass production for the flexion crystal oscillator featuring such small thickness that can be processed even through the photo etching, by securing the electrode-shaped disposition which can be excited strongly and also lowering the impedance level. CONSTITUTION:The distortion is almost even in the Z direction for the vibration of the tuning fork and then varies linearly in the X direction to become zero at the center with the code inverted. In order to secure the strong excitation, the electric line of force must be made to pass through the region featuring the big distortion. For this purpose, width W1 is set to 30-50% of width W2 of the main surface for electrodes 11b and 12a which are formed on the main surface of tuning fork type crystal oscillator 1. And the strong excitation becomes possible gradually by decreasing gradually the width of electrodes 11b and 12a on the main surface from the value which is equivalent to the main surface width of the leg. The part of electrodes 11a and 12b each on the side surface protrudes over the main surface for the convenience of the electrode connection and the mask structure at the time of evaporation. And protruded part 14's width W3 is set under 20% of the width of the main surface in order to prevent the lowering of excitation.
