CORRECTING DEVICE OF DEFLECTION EFFECT CAUSED BY CONVERGED VOLTAGE FLUCTUATION IN THREE-COLOR CATHODE-RAY TUBE WITH IN-LINE CATHODE

摘要

In order to avoid the phenomenon of the deflection of the spots red and blue of a trichromatic tube to the cathodes in line, as a function of variation of the focusing voltage, it increases the holes 5, 6, corresponding to these two colors, over a distance d from 0,1 to about 0,2 mm. & br / (see appended drawing in bopi) & br / & & br /
