    摘要: A color cathode ray tube includes a magnetic shield of generally truncated pyramidal shape housed in its funnel portion and an electron beam deflection device. The magnetic shield is configured such that a magnetic shield-core distance between an end of a magnetic core of the deflection device facing toward the phosphor screen and an end of the magnetic shield facing toward the electron gun is approximately constant for section plane angles &thgr; in a range of 0° to 360°, the magnetic shield-core distance being measured in a section plane containing a longitudinal axis of the cathode ray tube and being inclined at the section plane angle &thgr; with respect to a horizontal scanning direction of the electron beams.

    摘要: A color cathode ray tube has a vacuum vessel including a panel portion having a phosphor screen on its inner face, a neck portion and a funnel portion jointing the neck portion and the panel portion; an electron gun assembly including an electrostatic main lens disposed in the neck portion; a deflection yoke arranged around the neck side of the funnel portion for deflecting three in-line arranged electron beams emitted from the electron gun assembly to the phosphor screen; and a 2-pole ring magnet arranged around the neck portion for adjusting the trajectories of the electron beams. The 2-pole ring magnet is arranged to have its center closer to the phosphor screen than is the center of the electrostatic main lens of the electron gun assembly. The value, as calculated by dividing the value of the radial component amplitude of the magnetic field distribution of the 2-pole ring magnet on the circumference of a circle having a radius of the s-size, by the value of the circumferential component amplitude, is 0.86 to 1.38, and preferably 0.955 to 1.275.

    摘要: A color cathode ray tube comprises a vacuum vessel including a panel portion having a phosphor screen on its inner face, a neck portion and a funnel portion joining the neck portion and the panel portion. An inline electron gun is disposed inside of the neck portion and includes a main lens and cathode producing a center electron beam and two side electron beams. A deflection yoke for deflecting the electron beams and a pair of 2-pole ring magnets for adjusting electron beam trajectory are disposed around the neck portion. The 2-pole ring magnets have a magnetic flux density distribution at a circle which is concentric with the ring magnets, wherein the radius of the circle corresponds to the distance between adjacent electron beams at the main lens. The ratio of the amplitude of the flux density in the radial component compared to the amplitude of the flux density in the circumferential component is 0.86 to 1.38 on the circle.
