    • A color television picture tube of three in-line gun type wherein a ring-shaped ferrite permanent magnet or magnets are disposed around a neck portion of the tube, at least a pair of mutually-opposing pole pieces made of highly permeable magnetic material are provided within the tube neck portion as a part of the gun assembly so as to be magnetized by the ring magnet or magnets and to form an electron beam magnetic focusing lens system. In the picture tube, the pole pieces are each of a substantially elliptical cross section as viewed from a plane perpendicular to the tube axis, and spaces are provided between an inner wall of the tube neck portion and the pole pieces to accommodate support rods for gun assembling. There are selected to fall in particular ranges the ratio of the outer diameter to inner diameter of the permanent magnet, the ratio of the thickness to inner diameter thereof, the ratio of the thickness to gap length between the opposing pole pieces, and the ratio of the tube-axial length of the pole piece disposed on the side of a phosphor screen to the tube-axial length of the pole piece disposed on the side of cathode electrodes.

    • 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.
    • 至少两对辅助线圈在偏转线圈的外侧设置在相对于所述偏转线圈的水平方向的中心轴对称的位置处,并且在阴极射线的轴线方向上彼此分离 管。 至少两对辅助线圈分别设置在磁芯的纵向中心的前面和后面。 辅助线圈具有比其另一长度长的水平长度。 沿着偏转线圈前方和后方产生的不必要的辐射磁场被抑制的方向向第一对辅助线圈提供水平偏转电流,并且水平偏转电流被提供给第二对辅助线 在偏转线圈背面产生不必要的辐射磁场的方向上增加线圈。 因此,通过具有简单结构且不需要大空间的校正装置,可以在偏转线圈的前方和后方同时抑制不必要的辐射。
