Abstract: PURPOSE:To avoid the change in quality and the corrosion of the surface of a thick film electrode to stably adhere a thin film thereto, for improving the reliability thereof, by providing a metal-plated layer between a thin film common electrode and the thick film electrode. CONSTITUTION:A thick film thinned paste of Ag, etc. is printed and baked to form a thick film electrode 13.

IPC: H04B15/06
Filed: 1995-06-28
Abstract: PURPOSE: To eliminate the need of preliminary data input and to reduce reception faults by the unwanted radiation of clock signals with simple constitution by switching the frequency of the clock signals with a prescribed interval at the time of detecting reception signals. CONSTITUTION: A control means 50 synchronizes a control operation by the clock signals outputted from a clock oscillation means 30 and a shift control means 51 is activated when a reception frequency is changed. When the reception signals from a signal detection means 35 are confirmed, the shift control means 51 controls a shifting means 34 and grounds the other terminal of a capacitor 32. Thus, a clock frequency is shifted for a prescribed range corresponding to the capacitance of the capacitor 32. In a state where the clock frequency is shifted, the reception signals in the reception frequency are not present when the reception signals are the higher harmonic of the clock signals. When the reception signals are external signals, the reception state of the signal detection means 35 is continued.
