Filed: 1989-06-06
Abstract: PURPOSE:To obtain a binary PSK transmission wave with superior balance without applying adjustment by processing all the signals as digital signals up to a modulation circuit. CONSTITUTION:An IF signal generation circuit 1 outputs a rectangular repetitive pulse with a duty factor 50% having a prescribed first frequency lower than the band frequency of a communication channel in use as an IF signal, and the IF signal S is transmitted selectively to a succeeding stage with a transmission control part 2 based on the value of a binary signal for control.

Both input signals supplied also at the PSK modulation circuit 3 are the digital signals. Thereby, it is possible to obtain the binary PSK transmission wave with superior amplitude balance with-output applying the adjustment.

Title: Etching method
Inventor: HIRAYAMA MAKOTO
IPC: H01L21/302
Filed: 1979-11-01
Abstract: PURPOSE:To obtain a micro-pattern with higher reproducibility by a method wherein the optimum etching condition is determined on detecting the deflection of a photoresist film accompanied by the progress of etching, using the reflected waves of laser beams. CONSTITUTION:A poly-Si layer 7 is formed on an Si substrate 1, and photoresist masks 81-83 which are respectively L1>L2>L3 wide are laid on the layer. When the etched side of the mask 83 becomes t1X2>LB as etching progresses, a drop in a vertical direction is produced because the mask 83 is deflected as the layer 7 supporting the mask is being removed. The drop can be detected if these monitor patterns are observed continuously after the commencement of etching, making it possible to find out the optimum point of time for etching. This constitution enables the micro-pattern to be formed with superior reproducibility.
