DEFLECTION YOKE FOR COLOR CATHODE-RAY TUBE

摘要

PURPOSE: A deflection yoke is provided to be able to calibrate the divergence caused by the asymmetrical current in a horizontal deflective coil. CONSTITUTION: The deflection yoke(41) is composed of; a picture distortion calibrating coil; a couple of horizontal deflective coils and a couple of vertical deflective coils; an annular DY core surrounding the horizontal and vertical deflective coils; a couple of coils rolled on a monocoil; a bias coil(55) rolled on the monocoil; a bridge circuit having four inductors, a couple of input terminals and a couple of output terminals to easily calibrate the divergence by freely controlling the waveform without the expensive saturable reactor by providing the current flowing through the bias coil to a voluntary waveform from the outside of the deflection yoke.
