Abstract: A color cathode-ray tube (20) in which, opposing to a color fluorescent screen (5) so configured that stripes (9) of luminescent materials each capable of emitting light of a color are arranged in parallel to each other in a predetermined order, an aperture grille (10) in which a number of slits (4) extending in the longitudinal direction of the stripes (9) are made in parallel to each other is provided, the aperture grille (10) is so configured as to stretch a thin plate (1) having the slits (4) on a frame (3) with a required tension in the longitudinal direction of the slits (4). The thin plate (1) is a thin high purity iron plate having a thickness of 0.05 mm or less. Since the controllability of the widths of the slits in manufacturing is improved by virtue of the specified thickness of the thin plate, the precision and productivity of the aperture grille can be improved and the weight thereof can be reduced. Further, a fine structure screen for color cathode-ray tubes can be manufactured.

Abstract: PROBLEM TO BE SOLVED: To provide a cathode ray tube capable of effectively suppressing color deviation generating in operation time without changing the total correcting amount set in design. SOLUTION: Pins 26a, 26b of a panel 1 are positioned in the places displaced by the specified distance from the central position in the X direction. When heated during operation, an aperture grille 11 moves in the X+ direction by the elongation of frames 22a-22d and that of supporting springs 24a-24d. At the same time, the aperture grille 11 moves in the X- direction by the same distance by the bending of a holder 25b, and the relative distance between the aperture grille 11 and the fluorescent screen is not changed as a whole.

Abstract: PURPOSE: To prevent a number of filaments from deflecting with their own weight when welding a mask original plate to a frame by providing a support which, when the mask original plate is placed on the frame pressurized, supports the mask original plate placed inside the pressurized frame. CONSTITUTION: A support 21 is provided which, when a mask original plate is placed on a pressurized frame 1, supports the mask original plate placed inside the frame 1. The upper surface of the support 21 forms a cylindrical surface to fit the shape of a mask. The support 21 is fixed to a fixing portion 22 via leg members 21a, 21b. After the frame 1 is placed in a predetermined position on a mount 13, the frame 1 is pressurized by a hydraulic cylinder so that its opposite sides 1A, 1B come close to each other. In this case, the outside of the opposite part 1A of the frame 1 is fixed by a block 17, and a block 15 is made to abut to the outside of the other opposite part 1B and pulled by the piston of the hydraulic cylinder, so that the opposite parts 1A, 1B of the frame 1 are pressurized. Under these conditions, the mask original plate is electric seam welded and the frame 1 is depressurized.

Abstract: PURPOSE: To effectively evade the vibration of a reed screen state mask in a cathode ray tube, wherein an electron beam, emitted from an electron gun, is landed on a corresponding phosphor by the reed screen state mask being arranged in the inner side of a fluorescent surface. CONSTITUTION: In a frame body 11, wherein a reed screen state mask is fixedly retained in the inside of a cathode ray tube, the frame body 11 is formed so that a frame portion 11H can recede from a fluorescent surface at both ends in a horizontal direction, compared with a case where the frame body 11 is formed by a curved surface having a single radius in the horizontal direction.

Abstract: PURPOSE: To easily weld a clamp original plate to a frame without being influenced by a size of a color selecting electrode by making it workable even if a longitudinal directional clamp margin of a mask original plate is fairly short. CONSTITUTION: In order that a large number of slits SL to pass electron beams of three colors are respectively formed in the respective clearances of a large number of filaments L, an under surface of a mask original plate 2a stretched in the outer peripheral part 2P is supported with a mask support plate 17, and the four corners of the mask original plate 2a are respectively outward pulled by clamps 16a to 16d. Afterwards, still in a condition where the four corners of the mask original plate 2a are respectively outward pulled by the clamps 16a to 16d, the mask support plate 17 is removed, and a frame 1 is immediately pushed against the outer peripheral part 2P of a large number of filaments L of the mask original plate 2a from below the mask original plate 2a, and the outer peripheral part 2P of a large number of filaments L of the mask original plate 2a is welded to the frame 1.
