Inventor: SADO RIYOUICHI
IPC: H01B13/00
Filed: 1979-11-20
Abstract: PURPOSE:To uniformalize the quality by combining a process arranging eleectroconductive linear bodies in parallel on an elastomer sheet, a process bending and transforming the linear bodies into waveforms and a process slicing the sheet together with the linear bodies. CONSTITUTION:The electroconductive linear bodies 1 made of metal are embedded in parallel in the elastomer sheet 2 and thereby a sheet S is formed. When the sheet S is inserted in dies 3 and 4' at least one surface of which is in the form of waves and pressed, the linear bodies 1 are transformed regularly into the form of waves, while maintaining the parallel arrangement with each other. Finally, the sheet S whose linear bodies 1 are transformed into the form of waves is sliced in the direction perpendicular to the direction of arrangement of the linear bodies 1 and thereby the elastic structure body is formed. Since the linear bodies 1 are made to be in the form of waves after they are arranged in parallel and in a regular manner on the elastomer sheet 2, the linear bodies 1 are arranged regularly at equal intervals.

Title: Power amplifier
Inventor: YOKOTA TAKAHIRO
IPC: H03F3/20
Filed: 1992-06-10
Abstract: PURPOSE:To improve the voltage utilization factor of an amplifier element when an output power level is set small while increase in amplitude distortion is suppressed by keeping an operating point of the amplifier element within an active area at all times and keeping a voltage amplitude of an output signal obtained therefrom constant. CONSTITUTION:When a mobile station receives a transmission power control command from a radio base station, a control section 23 obtains control information and gives the information to a variable attenuator 43, a class A power amplifier 21, and variable reactance elements 241-243. That is, when the operating point of the amplifier 21 is constant, the current gain rate is proportional to an input power level, but an output signal with a voltage waveform of a maximum amplitude is obtained from an input signal whose level is set small and a voltage utilization factor is made constant. Furthermore, since the operating point of the amplifier 21 is set to a minimum value under the control of the control section 23 within a range of a no distortion maximum output, an average power consumption at each level of the reduced transmission power is reduced in response to the transmission power control command and the power efficiency is improved.
