    摘要： An electron gun for color-picture tube device comprises a final accelerating electrode (9) and a focusing electrode (8a, 8b) divided into plural electrode units in the axial direction of the tube. A first focusing electrode unit (8b) adjacent to the final accelerating electrode (9) is connected to a second focusing electrode unit (8a) adjacent to the first focusing electrode unit (8b) through a resistor (11). A focusing voltage being changed in synchronous with the deflection of an electron beam is applied to the first focusing electrode unit (8b). The resistor (11) is used for removing the a.c. components from the focusing voltage. Then, the removed focusing voltage is applied to the second focusing electrode (8a). For the electron beam deflected on the peripheral part of the screen, a quadrupole lens is formed. On the first focusing electrode unit side opposite to the second focusing electrode unit are formed first electron beam path holes (13) whose major axes extend horizontally. On the second focusing electrode unit side opposite to the first focusing electrode unit are formed second electron beam path holes (12) whose major axes extend vertically. As a result, the quadrupole lens serves to suppress a halo portion.

    摘要： A color picture tube apparatus comprises an envelope including a funnel(11), a face plate(12) and a neck(17), a phosphor screen(15) on an inner surface of the face plate, an electron gun structure(16) in the neck of the envelope for generating at least one electron beam, resistor means(120) for supplying predetermined voltage to the electron gun structure, and deflection means(18) for generating non-uniform deflection magnetic field to deflect the electrom beam. The electron gun structure includes a focusing electrode(70) including first means(74) for generating an asymmetric converging electric field near the focusing electrode having a relative strong converging action in one direction compared with the converging action in another direction perpendicular to the one direction, an accelerating electrode(100) including second means(101) for generating an asymmetric diverging electric field near the accelerating electrode having a relative strong diverging action in the one direction compared with the diverging action in the other direction, and at laest one intermediate electrode(80), (90) between the focusing electrode and the accelerating electrode for separating the converging electric field from the diverging electric field.

    摘要： An electron gun for color-picture tube device comprises a final accelerating electrode (9) and a focusing electrode (8a, 8b) divided into plural electrode units in the axial direction of the tube. A first focusing electrode unit (8b) adjacent to the final accelerating electrode (9) is connected to a second focusing electrode unit (8a) adjacent to the first focusing electrode unit (8b) through a resistor (11). A focusing voltage being changed in synchronous with the deflection of an electron beam is applied to the first focusing electrode unit (8b). The resistor (11) is used for removing the a.c. components from the focusing voltage. Then, the removed focusing voltage is applied to the second focusing electrode (8a). For the electron beam deflected on the peripheral part of the screen, a quadrupole lens is formed. On the first focusing electrode unit side opposite to the second focusing electrode unit are formed first electron beam path holes (13) whose major axes extend horizontally. On the second focusing electrode unit side opposite to the first focusing electrode unit are formed second electron beam path holes (12) whose major axes extend vertically. As a result, the quadrupole lens serves to suppress a halo portion.
