摘要： In a color cathode ray tube apparatus of this invention, an electron beam forming unit of an electron gun outputs electron beams to have an interval of 3.5 to 6.0 mm between adjacent beams, and a ratio of a neck inner diameter to the interval between the adjacent electron beams is 5.1 or more.

摘要： In an electron gun assembly, electron beams emitted from cathodes are focused in first cross-over and accelerated and controlled by grids along three axes arranged in-line. The controlled electron beams are weakly converged by unipotential lenses and are converged in a vertical plane by a common single electron lens having a lens power which is varied in accordance with a horizontal or vertical deflection of the electron beams. The converged electron beams form second cross-over on the axes which are shifted along the axes are diverged from the second cross-overs. The diverged electron beams are further focused and converged onto a screen by a main lens.

摘要： In a color cathode ray tube apparatus of this invention, if an outer diameter of a neck having a cylindrical shape is represented by D.sub.N and an interval of adjacent electron beams at a screen-side end portion of an electron gun is represented by Sg, a value D.sub.N /Sg is 8.0 or more. A deflection means has a saddle-type horizontal deflection coil for deflecting electron beams in an in-line direction. If the length of the deflection means in a direction of the tube axis is represented by l.sub.H all, l.sub.H all is 90 mm or more.

摘要： A color cathode ray tube apparatus is provided with an electron gun which has a common large-aperture electron lens on which three electron beams are incident. Since the electron gun has individual electron lenses for individual electron beams, the electron beams can be properly converged and focused on a screen. Thus, the apparatus enjoys a satisfactory picture characteristic.

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： In an electron gun assembly, three electron beams emitted from cathodes are passed through an electrode arrangement in which two intermediate electrodes are arranged between focusing are accelerating electrodes. A focusing voltage which is varied depending on an deflection of the electron beam is applied to the focusing electrode and an accelerating voltage is applied to the accelerating electrode. A resistor is connected between the accelerating electrode and the earth through a variable resistor and intermediate points of the resistor are connected to the intermediate electrodes. Thus, convergent and divergent lenses are formed between the focusing electrode and the intermediate electrode and between the accelerating electrode and the intermediate electrode. The lens powers of the convergent and divergent lenses are varied in accordance with the adjustment of the variable resistor.

摘要： In a color cathode ray apparatus, three electron beams emitted from electron gun assembly are correctly converged on a peripheral region of a peripheral region of a phosphor screen and are weakly converged on a center region of the phosphor screen by static convergence means. The electron beams are also converged by dynamic convergence means so as to correct the weak convergence in accordance with a horizontal deflection of the electron beams. Thus, the electron beams can be correctly converged all over the phosphor screen.
