Title: Power amplifier
Inventor: MAKINO KENICHI
IPC: H03F3/20
Filed: 1986-04-16
Abstract: PURPOSE:To compensate the reduction of efficiency by cancelling the reverse flow of a transistor (TR) by a current flowing to a coil connected in parallel with an output of a power amplifier circuit without adding any high speed diode thereby preventing the increase in the power loss due to the reverse flow. CONSTITUTION:The impedance of a DC blocking capacitor C is lowered sufficiently and a rectangular output voltage V0 is fed across a compensation coil L. Since the saturated resistance of a FET is sufficiently low, a current i3 of the coil L has a waveform being the time integration of an output voltage v0 at the steady-state, that is, a triangle wave. In making the amplitude of the current i3 equal to a maximum value of a negative portion i12 of a current i4 of a TR 1, the current i12 is cancelled completely by the current i3. The relation of L=E/8f0Im, where E is a power voltage, f0 is the operating frequency, I3 is the amplitude of the current i3 and Im is the maximum value of the current i12 (=I3) and it is decided already at the circuit design.

IPC: H05K7/12
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a unit housing device in a communication equipment with a structure that can guide even a wide unit smoothly without being latched due to lateral shifting when the unit is inserted or removed. SOLUTION: A guide groove that is V-shaped in cross section (V-groove 9) is provided on the unit mounting part side. On the unit 1 is provided a guided part 8 that is engaged to the guide groove 9 and slid to move. Thus, if the unit 1 is to tilt toward right or left against the moving direction, the guided part 8 starts climbing up the slope of the guide groove 9. As a result, a force to move the guided part 8 toward the center of the guide groove 9, that is the force to correct the tilt of the unit 1 is produced and the tilt is prevented. Therefore, the unit 1 can be guided smoothly without being latched due to lateral oscillation when the unit 1 is inserted into or removed from the unit mounting part.
