    摘要： At least two pairs of auxiliary coils are disposed externally on a deflection yoke at positions which are symmetric with respect to the central axis of a horizontal direction of said deflection yoke and which are separated from each other in the direction of the axis of a cathode ray tube. At least two pairs of auxiliary coils are respectively disposed in front of and at the back of the longitudinal center of a magnetic core. The auxiliary coils have a horizontal length which is longer than its another length. A horizontal deflecting current is supplied to the first pair of auxiliary coils in the direction in which unnecessary radiant magnetic fields generated in front of and at the back of the deflection yoke are suppressed, and a horizontal deflecting current is supplied to the second pair of auxiliary coils in the direction in which an unnecessary radiant magnetic field generated at the back of the deflection yoke is intensified. In consequence, unnecessary radiation can be suppressed simultaneously in front of and at the back of the deflection yoke by a correction apparatus which has a simple structure and which requires no large space.

    摘要： A deflection yoke having cancelling loop coils for reducing undesired portions of a horizontal deflection magnetic field generated by a deflection yoke body without mislanding. The cancelling loop coils generate a cancelling magnetic field which includes two peaks in a front region and a rear region of the deflection yoke body in which the undesired field portions exist, respectively. The peaks are opposite in direction to the horizontal magnetic field generated by the deflection yoke body, respectively, with same ratio to the deflection magnetic field, so that the undesired magnetic field portions are under-corrected in the front portion and over-corrected in the rear portion.

A first convergence yoke is disposed outside the neck part of the cathode-ray tube for forming magnetic paths together with the magnetic pole pieces. A first coil is wound on a first convergence yoke to generate a magnetic field for correcting horizontal misconvergence between the center beam and a side beam on a side of the center beam. A second coil is wound on the first convergence yoke to generate a magnetic field for correcting horizontal misconvergence between the center beam and a side beam on the other side of the center beam. A third coil is wound on the first convergence yoke to generate a magnetic field for correcting vertical misconvergence between the center beam and both side beams. Furthermore, a second convergence yoke is disposed on the neck part of the cathode-ray tube at a different position from the first convergence yoke. A fourth coil is wound on the second convergence yoke to generate a magnetic field for correcting vertical misconvergence between both side beams.
