IPC: H03D3/00
Filed: 1991-12-25
Abstract: PURPOSE:To provide the orthogonal demodulator for digital phase modulation with simple configuration by comparing digitally an input modulation signal with an internal reference signal and counting its binary signal in a proper timing. CONSTITUTION:A received input modulation wave is inputted to a demodulator as a signal 100 under the control of frequency conversion. Then the signal is subject to noise band limit and waveform shaping by a BPF 101 and the resulting signal results being a signal 115 whose envelope is constant by a limiter 102. An internal reference signal 109 is distributed into two, the one is frequency-divided and the result is a reference signal 114 for orthogonal detection whose phase differs by 90 deg. at a phase shifter 105. The signal 114 is mixed with a limiter output 115 by an EX-OR 103 and the result is outputted to a post-stage for a prescribed period by a gate 104. Information corresponding to the reference signal is extracted by counting the signal at a counter 106 in response to the gated block.

Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To enhance the adhesiveness of a resist film to base thereof by adhering thiol to a surface to be formed with a resist film, then applying the liquid resist to the surface. SOLUTION: A piezoelectric element piece formed with an electrode film forming metal film (a gold layer Au and a chromium layer Cr) is dipped in a treatment solution obtained by dissolving thiol with a solvent such as alcohol or ketone.

Photoresist PR2 is applied to a surface of the gold layer Au through the thiol later, and the thiol layer is interposed between the surface of the gold layer Au and the photoresist PR2 (resist mask M2). Since adhesiveness of the surface of the gold layer Au to the photo resist PR2 is strung, peeling of the resist film from the gold layer Au and intrusion of etching liquid between the surface of the gold layer Au and the resist mask Ms are prevented.
