Abstract

PURPOSE: To reduce the deterioration of the focus properties caused by the luminous spot deflection distortion, by enclosing the electronic gun onto the vertical line including the tube axis so that the 3-electron beam may not be discharged and forming the horizontal deflection magnetic distribution into a barrel type and the vertical direction into a pincushion type respectively.
