Abstract

PURPOSE: To equalize the voltage necessary for deflection in two directions crossing in normal to each other by providing a net-like cylindrical plane electrode between the fluorescent face and the deflcction plate and making axis of the cylinder parallel with the deflection plate and perpendicular to the axis of the tube.
