    摘要: A cathode ray tube according to the invention comprises an internal conductive film arranged on the inner wall surface of the envelope and extending from the funnel section to the neck section and a high resistance conductive film arranged in the neck section to contact the internal conductive film at an end of thereof and surround part of the electron gun assembly. The high resistance conductive film shows an electric resistance higher than that of the internal conductive film. Additionally, in a cathode ray tube according to the invention, the electric resistance of the high resistance conductive film in terms of per unit length along the axis of the tube is lower at and near the contact region held in contact with the corresponding end of the internal conductive film than at and near the opposite end of the high resistance conductive film.

    摘要: In a color cathode ray tube apparatus having an electron gun assembly for emitting three electron beams disposed in one line, the electron gun assembly has at least first, second, and third electrodes G5, G7, and G9 applied with a voltage which changes in synchronization with deflection of electron beams. The first electrode and an electrode G4 adjacent thereto form first eccentric lenses for deflecting a pair of side beams in a direction in which the side beams extend to be close to the center beam. The second electrode and an electrode G6 adjacent thereto form second eccentric lenses for deflecting the side beams in a direction in which the side beams extend to be apart from the center beam. The third electrode and an electrode G8 adjacent thereto form third eccentric lenses for deflecting the side beams in a direction in which the side beams extend to be close to the center beam. An electron lens common to the three electron beams is formed between the second and third eccentric lenses. It is possible to realize a color cathode ray tube apparatus which displays a high quality image over the entire area of the screen by means of these electron lenses.

    摘要: An electron gun for color-picture tube device comprises a final accelerating electrode and a focusing electrode divided into plural electrode units in the axial direction of the tube. A first focusing electrode unit adjacent to the final accelerating electrode is connected to a second focusing electrode unit adjacent to the first focusing electrode unit through a resistor. A focusing voltage being change in synchronous with the deflection of an electron beam is applied to the first focusing electrode unit. The resistor is used for removing the a.c. components from the focusing voltage. Then, the removed focusing voltage is applied to the second focusing electrode. 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 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 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, a face plate and a neck, a phosphor screen on an inner surface of the face plate, an electron gun structure in the neck of the envelope for generating at least one electron beam, resistor means for supplying predetermined voltage to the electron gun structure, and deflection means for generating non-uniform deflection magnetic field to deflect the electron beam. The electron gun structure includes a focusing electrode including first means 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 including second means 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 least one intermediate electrode between the focusing electrode and the accelerating electrode for separating the converging electric field from the diverging electric field.
