摘要： In a color cathode-ray tube of the plural-beam type wherein the beams originate on a horizontal or vertical straight line and are directed into fields produced by a horizontal-vertical electromagnetic deflection yoke at predetermined incident angles to each other so as to converge at a color screen, magnetic shielding means, for example, secured to electron beam convergence plates, are disposed for selectively shielding at least one of the beams from the leakage flux produced by the horizontal-vertical electromagnetic deflection yoke in deflecting the beams in the direction of the line of origination thereof, whereby such leakage flux acts selectively on only the unshielded beam or beams for correcting a deviation between the positions of rasters on the color screen produced by the plural beams.

摘要： A degaussing structure for a video tube which serves to demagnetize the tube and an apertured beam-selecting member in the tube. A shroud surrounds the forward portion of the tube and the apertured beam-selecting member. A pair of degaussing coils which are connected in series are wrapped around cutout areas in the shroud at the top and bottom thereof such that the magnetic flux produced by the current carrying coils is in a direction to degauss the apertured beam-selecting member.

摘要： In a color picture tube having an apertured beam selecting grill or mask through one or more electron beams are made to land on predetermined color phosphors applied to the face plate of the tube, thermal expansion of the grill or mask is compensated for, so as to avoid mislanding of the beam or beams, by providing an auxiliary magnetic deflection means located in back of the main magnetic deflection or scanning means and operative in dependence on the operation of the main deflection means to produce magnetic flux in opposition thereto. The current flowing in the auxiliary magnetic deflection means is decreased with increasing temperature by means of a thermosensitive magnetic means so as to similarly decrease the magnetic flux opposing that of the main deflection means, whereby the effective center of deflection of the beam or beams is shifted rearwardly in response to increasing temperature.

摘要： In a color picture tube, particularly of the single-gun, pluralbeam-type, in which a central beam and two side beams lying in a common plane are focused on the color phosphor screen, the side beams are angled with respect to the central beam to converge with the latter at a common point on the beam-selecting grid or mask, and the beams are simultaneously deflected to scan the screen; misconvergence of the beams is corrected by permanent or electromagnets arranged at opposite sides of the central beam and producing respective magnetic fields having lines of magnetic flux extending generally perpendicular to the common plane of the beams and in opposed directions, and the effects of such magnetic fields on the adjacent side beams and on the central beam are varied either by independent displacement of the magnets toward and away from the central beam or by controlling the strengths of the fields.

摘要： In a cathode ray tube having a curved phosphor screen, a shadow mask having apertures therein and electron beam generating means for generating three in-line electron beams aligned in a horizontal direction, the apertures of the shadow mask are aligned in the form of barrel-shaped lines extending in a horizontal direction and are aligned in the form of pin-cushioned lines extending in a vertical direction. The apertures are circular at the central portion of the mask but become gradually elliptic as the peripheral portion of the mask is approached from its center, and the longer axis of the elliptic apertures are inclined at predetermined angles to a horizontal direction corresponding to their particular locations.
