    Abstract: PURPOSE:To widen the fitting range of a permalloy to shorten the time for adjusting the image quality by providing the taper surface in the tip of a deflecting yoke spacer to be inserted between the outer surface of a bulb and the deflecting yoke to position the deflecting yoke. CONSTITUTION:A deflecting yoke spacer 8 is inserted to a clearance between the outer surface of a glass bulb and a deflecting yoke 2 of a picture tube to position the deflecting yoke temporarily for adjustment of the image quality. At this stage, a permalloy 10 is inserted between the deflecting yoke 2 and the bulb to correct the convergence failure. Since the spacer 8 has the tapered surface 3 at the tip thereof in the inserting direction, a possible range of fitting of the permalloy 10 is increased in the spacer direction by a dimension of the cut tip. Consequently, necessity of re-positioning of the deflecting yoke 2 is reduced. The time for adjusting the image quality is thereby shortened, and the material cost for the cut tip is reduced and the spacer 8 itself can be lightened by weight of the cut tip.

    Abstract: PROBLEM TO BE SOLVED: To provide a CRT device which can easily positioning a deflection device unit to enable an effective fixation. SOLUTION: A front surface side aperture part of a deflection device unit 120 has an annular spacer holder 150. The spacer holder 150 is provided with four installation holes 152 into which four spacers 170 are fitted so as to be removed freely therefrom and which are provided around an axis at 90 deg. intervals. The inside of the installation hole 152 is provided with a nail part which locks the spacer 170. The spacer 170 has two-fork type base ends 174A, 174B separated from a tip 172, and the outside portions of the base ends 174A, 174B have engaging tooth parts 176A, 176B. The engaging tooth parts 176A, 176B are selectively engaged with nail parts 154A, 154B of the installation hole 152 to thereby adjust a projecting a mount of the tip 172 so as to adjust a position of a deflection device unit 120 to a CRT 110.

    Abstract: PURPOSE:To obtain a line correction method for an electron beam by which landing correction close to a complete method is executed without complicated device configuration. CONSTITUTION:A correction magnetic field M3 is generated in the same direction as the earth magnetism M1 in the case of degaussing, and the correction magnetic field M3 is overlapped on the earth magnetism M1. In this case, the strength of an inverted magnetic field M1 generated in the inside of the magnetic shield plate 1 is made equal to the intensity of the earth magnetism M1. Then the correction magnetic field M3 is lost.

    Abstract: PURPOSE:To reduce occurrence of vertical stripes by equipping an thin aperture grille plate having grid elements, and wires arranged substantially orthogonally to the grid elements and stretched over the thin aperture grille plate with the coefficient of friction being made small with respect to the grid elements. CONSTITUTION:Wires 3 which are made small in the coefficient of friction with respect to tape-shaped grid elements 2a constituting a thin aperture grille plate 2 are stretched over the taper-shaped grid elements 2a surfaces. For this reason, the wires 3 which have once been displaced become easy to return to their original positions, by which it is possible to prevent occurrence of vertical stripes (pitch moire) on the picture screen. Further, in order to make small the coefficient of friction, a carbon coat (film) serving as a lubricating agent is applied onto the surface of tungsten wires of the damping wires to lower the coefficient of friction. This prevents vertical stripes (pitch moire) from being produced on a video screen of a trinitron type CRT and, at the same time, damps the resonance of the thin aperture grille plate quickly.
