Abstract

A CONVERGENCE MAGNET ASSEMBLY FOR A CATHODE RAY TUBE COMPRISING THREE PAIRS OF MAGNET RINGS POLARIZED RESPECTIVELY WITH P-POLE, 4-POLE AND 6-POLE, A PLURALITY OF SPACERS, EACH DISPOSED BETWEEN ADJACENT ONES OF THE MAGNET RING PAIRS FOR PREVENTING A ROTATION INTERFERENCE THEREBETWEEN, AND A NON- MAGNETIC HOLDER FOR HOLDING THE MAGNET RINGS AND SPACERS, WHEREIN THE CONVERGENCE MAGNET ASSEMBLY FURTHER COMPRISES A SEPARATE 6-POLE MAGNET FORMED IN A SPECIFIC ONE OF THE SPACERS FOR INDUCING ONE OR BOTH SIDE ONES OF RED, GREEN AND BLUE BEAMS TO BE DISPLACED AT A MINIMUM MAGNETIC FIELD STATE OF THE MAGNET RINGS TO INCREASE A CENTER CONVERGENCE VARIANCE. ACCORDING TO THE PRESENT INVENTION, THE THREE BEAMS CAN READILY BE STATICALLY CONVERGED IN A NO-ERROR TUBE. FURTHER,THE CONVERGENCE MAGNET ASSEMBLY IS CAPABLE OF BEING USEFULLY APPLIED TO EVEN ITC AUTOMATION AND BEING MANUFACTURED WITHOUT SETTING A DIFFERENCE BETWEEN MAGNETIC FLUX DENSITIES AND DISCRIMINATING MAGNET RINGS AT BEAM INLET AND OUTLET SIDES FROM EACH OTHER.(FIGURE 4)
