  • Apparatus for magnetizing a convergence device for in-line color-picture tubes and methods of adjusting convergence with such apparatus
    Patent number: 4395692
    Abstract: An apparatus is disclosed for magnetizing the convergence device of a color-picture tube including electrically excitable coils disposed around the tube neck and having their axes located in the convergence device plane. The cross sections of the coils in the convergence-device plane are greater than those perpendicular to this plane. This adaptation of the symmetry of the magnetizing coils to the symmetry of the convergence device makes it possible to exert a strong influence on the convergence device.
