    • In a color cathode ray tube in which a shadow mask 1 and an inner magnetic shield 2 are supported by a mask frame 31 and an electron shield 33 is provided in the mask frame 31, at least a part of the electron shield 33 is made to have a smaller anhysteretic magnetic permeability than the shadow mask 1, the mask frame 31 and the inner magnetic shield 2 when an applied magnetic field is 800 A/m (10 Oe). Since the magnetic resistance of the electron shield 33 increases, it is possible to reduce a leakage magnetic field from a tube-axis-side edge of the electron shield 33. Thus, a color cathode ray tube that reduces mis-landing due to a terrestrial magnetism and has no color displacement can be provided.

    • PURPOSE: A deflection yoke and a CRT device using the deflection yoke are provided to reduce power consumption without sacrifice of convergence performance as much as possible. CONSTITUTION: A deflection yoke(24) mounted around a glass bulb(20) of a CRT covers a predetermined area of the glass bulb, the predetermined area being where an outer shape of the glass bulb smoothly goes from circular to substantially rectangular along a tube axis of the CRT, and comprises a horizontal deflection coil disposed in a shape to fit with the outer shape of the glass bulb, and a funnel-shaped ferrite core disposed to surround the horizontal deflection coil, an inner shape of the ferrite core being circular throughout a length of the ferrite core.
    • 目的:提供使用偏转线圈的偏转线圈和CRT装置,以尽可能地降低功率消耗而不牺牲收敛性能。 构成:安装在CRT的玻璃灯泡(20)周围的偏转线圈(24)覆盖玻璃灯泡的预定区域,预定区域是玻璃灯泡的外部形状沿着管子从圆形平滑地延伸到大致矩形的区域 并且包括以与玻璃灯泡的外形相配合的形状的水平偏转线圈和围绕水平偏转线圈设置的漏斗状铁氧体磁芯,铁氧体磁芯的内部形状为圆形 在铁氧体磁心的整个长度上。
