    • Four magnetic pieces are provided inside the cup-shaped portion of a shield cup. Correction magnetic field generating faces at the tips of the magnetic pieces are opposed to each other and sandwich an electron beam. Correction can be conducted according to the astigmatism amount of three electron beams because a correction magnetic field corresponding to the strength of a deflection magnetic field can be generated easily by leading the deflection magnetic field absorbed by the principal face portion of each magnetic piece to the correction magnetic field generating face. Thus, the difference in astigmatism amount among the electron beams caused by the deflection magnetic field can be corrected. Therefore, a color cathode ray tube apparatus that can display images with a high resolution over the whole screen surface can be provided.
    • 在屏蔽杯的杯形部分内设置四个磁性片。 在磁片的尖端处的校正磁场产生面彼此相对并夹着电子束。 可以根据三个电子束的像散量进行校正,因为通过将由每个磁性片的主面部吸收的偏转磁场引导到校正,可以容易地产生与偏转磁场的强度相对应的校正磁场 磁场产生面。 因此,可以校正由偏转磁场引起的电子束中的像散差的差异。 因此,可以提供能够在整个屏幕表面上显示高分辨率的图像的彩色阴极射线管装置。

    • A color picture tube apparatus comprises cathodes, a control electrode, an accelerating electrode, a first focusing electrode, a second focusing electrode and a final accelerating electrode, a voltage applying means which applies a dynamic voltage which increases with increasing deflection angle to the second focusing electrode, a resistor which is connected between the first and second focusing electrodes. Electron beam through holes that are vertically oblong are provided at the facing sides of the second focusing electrode and the final accelerating electrode. A quadrupole electric field lens is formed wherein a focusing effect is obtained in the horizontal direction and a diverging effect is obtained in the vertical direction when the potential level of the second focusing electrode is higher than that of the first focusing electrode. A compensating means generates a combined focusing effect of the electric field lenses formed between the cathodes and the final accelerating electrode stronger in the horizontal direction than in the vertical direction when the potential levels of the first and second focusing electrodes are the same.
