Abstract: A color cathode ray tube comprises a vacuum vessel including a panel portion having a phosphor screen on its inner face, a neck portion and a funnel portion joining the neck portion and the panel portion. An inline electron gun is disposed inside of the neck portion and includes a main lens and cathode producing a center electron beam and two side electron beams. A deflection yoke for deflecting the electron beams and a pair of 2-pole ring magnets for adjusting electron beam trajectory are disposed around the neck portion. The 2-pole ring magnets have a magnetic flux density distribution at a circle which is concentric with the ring magnets, wherein the radius of the circle corresponds to the distance between adjacent electron beams at the main lens. The ratio of the amplitude of the flux density in the radial component compared to the amplitude of the flux density in the circumferential component is 0.86 to 1.38 on the circle.

Abstract: A color cathode ray tube apparatus comprising an electron gun assembly of inline type including an electron beam generating section designed to emit three electron beams having axes extending in the same horizontal plane and a main electron lens section designed to focus the three electron beams emitted from the electron beam generating section. The main electron lens section has at least three grids G5, GM and G6 arranged in the order mentioned from the cathode side. The distance between the axis of the hole for guiding the center beam, made in the grid most close to the cathode side, and the axis of either hole for guiding a side beam, made in this gird, is shorter than the distance between the common axis of the coaxial holes for guiding the center beam, made in the control, accelerating and focusing electrodes constituting the electron beam generating section, and the common axis of either group coaxial holes for guiding a side beam, made in these control, accelerating and focusing electrodes. Hence, the spot which either side beam forms on the center of the phosphor screen when the three electron beams are focused by convergence magnets has no halos extending in the horizontal direction of the screen. As a result, the resultant image can have high resolution at any part of the phosphor screen.

Abstract: An electron gun for a cathode ray tube includes a single cathode that emits thermions; first and second electrodes; a plurality of focus electrodes provided consecutively after the second electrode; an anode electrode mounted after a final focus electrode; and a support that supports the electrodes in an aligned configuration. The final focus electrode and the anode electrode are mounted opposing one another with a predetermined gap therebetween. If a lengthwise direction of phosphor layers forming a phosphor screen of the cathode ray tube is a Y axis direction, and a direction perpendicular to the Y axis direction is an X axis direction, an electron beam aperture formed in a portion of the final focus electrode opposing the anode electrode, and an electron beam aperture formed in the anode electrode have diameters in the X axis direction that are larger than corresponding diameters of electron beam apertures formed in the remaining electrodes.

Abstract: An electron gun includes a grid electrode having a thin plate portion in which an electron beam aperture is formed, wherein the thin plate portion is formed by using a die and punch die to bulge a portion of a metal plate in the plate thickness direction to such an extent as to correspond to the desired dimension of the thin plate portion to form a bulged portion and cutting the bulged portion. With this configuration, it is possible to eliminate a problem of the related art thin plate portion of a grid electrode for an electron gun formed by coining work, which is a rib is formed around the thin plate portion, to make the gap between the thin plate portion and a cathode narrower, since the diameter of the thin plate portion can be enlarged, and to provide beam apertures at arbitrary positions of the thin plate portion.
