Abstract

PURPOSE: To readily and accurately measure coil diameters from the voltages withdrawn from a synchronous oscillator by withdrawing the rotating angles when the photoelectric detectors provided at the end are cut off by the coil surface by turning of rotating arms from the synchronous oscillator as output voltages.
