Abstract
PURPOSE: To increase the deflecting efficiency of the electron beam by fixing through adhesion the permanent magnet onto the inner wall of the peripheral unit provided near the electronic gun which is incorporated in the CRT peripheral unit to reduce the current flowing to the deflection yoke and then applying the magnetic field of the permanent magnet to the magnetic field of the deflection yoke.
