AUTOMATIC VARIABLE CAPACITANCE CONDENSER

摘要

PURPOSE: An automatic variable capacitance condenser is provided to automatically control a condenser value for obtaining a resonance point from a desired frequency, thereby obtaining an optimized resonance point in an LC circuit. CONSTITUTION: Two electrodes(10) are faced with each other. Intervals of the electrodes are broadened and narrowed by using a worm gear and a motor. An end part of an electrode is sharply formed. A resonant circuit is formed by combining a coil and a condenser in series or parallel.
