    摘要： A method of making mask structure including two or more masks for a mask-focusing colour picture tube and the mask structure formed by the method. A plurality of apertured flat masks, each mask comprising an effective portion having apertures and a border surrounding the effective portion are stacked with the apertures aligned, then filling material is poured into the apertures. The filling material is solidified thereby fixing the flat masks together. The fixed masks are pressed into a predetermined curved shape. Then, the filling material is removed from the apertures and the masks are separated.

    摘要： The invention discloses a method of making a mask structure Including two or more masks for a colour cathode ray tube, for example, a mask focusing colour cathode ray tube. A plurality of apertured flat masks, each mask having an effective portion having apertures and non-effective portion surrounding the effective portion, are aligned and stacked with a predetermined gap between them. The gap is then filled with filling material which solidifies, thereby fixing the flat masks together. The fixed masks are simultaneously pressed into a predetermined curved shape. The filling material is then removed from the curved masks.

    摘要： In a color cathode ray tube, a panel (3) having a single faceplate (3-1) is coupled to a plurality of necks (5-1 to 5-12) through a plurality of funnels (4-1 to 4-12), respectively. A plurality of electron gun assemblies (6-1 to 6-12) are received in necks (5-1 to 5-12) and a plurality of deflection units (7-1 to 7-12) are mounted around the funnels (4-1 to 4-12), respectively. A screen (2) is formed on an inner surface of faceplate (3-1) and has a plurality of continuous segment regions (16-1 to 16-12) each of which is scanned with the electron beams emitted from the corresponding electron gun assembly (6-1 to 6-12) and deflected by the corresponding deflection unit (7-1 to 7-12). A shadow-mask (10) is so supported in the panel (3) as to face the faceplate (3-1). The electron gun assemblies (6-1 to 6-12) adjacent each other so arranged as to have a relative distance GS between the central axis thereof: where SG is a relative distance on the deflection plane, between the electron beams emitted from each of said electron gun assembly, d is a distance between predetermined effective apertures of the shadow mask through which the predetermined electron beams pass, the predetermined electron beams landing on endmost adjacent effective phosphor elements in each two adjacent ones of said segment regions, and m and n are integers, respectively.

    摘要： A colour cathode ray tube (11) includes a screen (15), a shadow mask and an electron gun section. The electron gun section comprises a plurality of separate unit electron guns (27,29,33). The screen is divided into a plurality of subregions (73,75,77,79) each of which is scanned by an individual unit electron gun. Each unit electron gun emits a single electron beam and in associated with an individual main deflection device for causing the beam to scan the electron gun's particular subregion of the screen and subsidiary deflection means (45,47,51) for effecting electron beam colour switching.

    摘要： In an electron gun assembly for a cathode ray tube, the center and side electron beams (3A, 3B, 3C) emitted from cathodes (9A, 9B, 9C) are incident on a main elec­tric lens (21). The center and side electron beams (3A, 3B, 3C) are focused, respectively. The side beams (3A, 3C) are over-converged and directed to an over-converged point by the main electric lens (21). The side beams (3A, 3C) emerged from the main electric lens (21) are deflected and corrected by a divergent lens (23) so that the center and side beams are converged on a proper converged point between the screen (30) and the over-­converged point (P).

    摘要： An electron gun for producing and directing at least one electron beam along a beam path comprises a beam forming section (6, 9, 11, 12) and a main lens section for focusing the electron beam. The main lens section includes first and second electrodes (13,14) arranged along the beam path and each having an aperture through which the electron beam is passed, and an auxiliary electrode (16) located between the first and second electrodes (13, 14) and having an aperture through which the electron beam is passed. The aperture of the auxiliary electrode (16) is wider than those of the first and second electrodes (13, 14). Different voltages are applied to the first and second electrodes (13, 14), and the auxiliary voltage between the voltages is applied to the auxiliary electrode (16). An electrostatic field formed between the first and second electrodes and under the influence of the auxiliary voltage is corrected by a correcting electrode (113, 114)
