Filed: 1994-07-06
Abstract: PURPOSE:To economically perform switching operation of output power without lowering high output power by providing desired output power by controlling the amplification of respective distributed signals in the process of amplifying, distributing an input signal and further adding amplified signal voltages and output it. CONSTITUTION:Control parts 5a and 5b set an operating state by outputting control signals to following stage amplifier parts 2a and 2b. An input signal S1 passes through a variable attenuator 10, is amplified by a preceding stage amplifier part 1 and inputted later to a power distributor 8. The signal inputted to the distributor 8 is distributed into two of equal amplitudes and equal phases and respectively amplified later by the following stage amplifiers 2a and 2b, and two signals are added again into one by a power circuit 9 and outputted later as a desired output signal S2 with high output power. Therefore, the switching operation of output power can be economically performed without lowering the high output power.

This increases the transmittancy of part of the layer 2 and the reflected light is visible  from the layer of the other parts. In the light transmitted part, the layer 1 appears black if it is  light absorbable. Color recording is easily obtainable depending upon the colors of the elements 2,  whether the layer 1 is reflective or light transmittable and further by the combinations of the  filters on the layer 3.
