Abstract: PURPOSE:To reduce the heating even by the operation with the high horizontal deflection frequency and improve the winding precision by bundling in parallel multiple conductor fine wires having the first deposition layer made of thermoplastic insulating material and the second deposition layer made of thermoplastic insulating material with a lower melting point to constitute the conductor wire of an deflecting coil. CONSTITUTION:Multiple fine wires 2 are merely bundled without being twisted, they are heated so that only the second deposition layer 5b made of the fine wires 2 with a lower melting point is melted. They are then cooled, the fine wires 2 are temporarily fixed together to form a unit conductor wire. This unit conductor wire 1 is wound on a deflecting coil former and molded. In this case, it is precisely wound without being untangled because the fine wires 2 are temporarily fixed together. Each unit conductor wire 1 can be wound at high density because the fine wires 2 are twisted together. After the unit conductor wire 1 is wound and molded, the first deposition layer 5a is heated and melted and cooled, thereby the unit conductor wire 1 is fixed together to form a deflecting coil.

Abstract: PURPOSE:To restrain the occurrence of rust for reducing a phosphor screen defect, and improve breakdown voltage characteristics of a color cathode-ray tube by electrically connecting a metal member having higher ionization tendency than iron to a support seat made of soft steel material. CONSTITUTION:A support seat 30 for positioning and supporting a panel 1 mainly comprises a soft steel material (iron material) as a base material, and the required section thereof is applied with paint. A part of the seat 30 is not applied with the paint, and the base material is exposed. Also, the lower side of the seat 30 is fitted with a metal block 36 (zinc block) mainly comprising zinc having higher ionization tendency than iron constituting the base material. In this case, when the block 36 having higher ionization tendency than iron as the constituent element of the seat 30 is electrically connected to the seat 30, the block 36 corrodes faster than the seat 30. Also, electrons generated at the time of the appearance of cation are supplied to the iron constituting the seat 30. As a result, the occurrence of rust on the seat 30 is restrained, thereby reducing a phosphor screen defect. At the same time, the breakdown voltage characteristics of a cathode-ray tube can be improved.

Abstract: PURPOSE:To prevent mis-landing due to repulsion among electron beams by setting horizontal overlap among three electron beams to be a half of a radius of an electron beam in the horizontal directly or below to cause a different delay among the three electron beams. CONSTITUTION:An electron gun 6 is of in-line type and consists of a B electron gun 16, a G electron gun 17, and an R electron gun 18. Then a delay time 27 is given to the B electron gun 16 and a delay time gamma is set to the G electron gun 17 with respect to the R electron gun 18 as a reference, where gamma is a half of the radius of an electron beam on a panel in the horizontal direction. The three electron beams are subject to deflection scanning by a deflection yoke 7 mounted to the outside of a funnel 4. Thus, the three electron beams are not overlapped at the same time and then an orbit portion causing repulsion among the electron beams close to each other is remarkably reduced and a picture with excellent color purity is obtained even at a high brightness.

Abstract: PURPOSE:To obtain a color picture tube generating no color drift on a screen by exposing an exposed layer with the displacement of a shadow mask against a panel by the preset quantity in the downward direction when the color picture tube is operated with its tube axis kept horizontal. CONSTITUTION:A displacing means 40 is provided on an exposing device, and a photosensitive film 18 and a phosphor slurry layer formed on the inner face of a panel 1 are baked via a shadow mask 6. The shadow mask 6 is forcibly displaced by the preset quantity in the downward direction of the panel side 44a when a color picture tube is operated with its tube axis kept horizontal for exposure, thus a phosphor screen is formed. When the tube axis is made vertical (panel is made horizontal), the matching relationship between three-color phosphor dots of the phosphor screen and the shadow mask is drifted, but when the picture tube is incorporated in a television set with the tube axis kept horizontal, the positional relationship between the three-color phosphor dots of the phosphor screen and the shadow mask becomes the same state as that when the photosensitive film 18 and the phosphor screen slurry layer are baked, and a picture tube generating no color drift is obtained.

Abstract: PURPOSE:To obtain a picture with no visual unsightliness by specializing aperture intervals to be included in the vertical length including the tube axis of a shadow mask and the aperture intervals in the position apart from the tube axis by a fixed distance in the horizontal direction. CONSTITUTION:A shadow mask type color picture tube is formed by regulating the outer peripheral line of a vertical axis end so that, when the vertical length including the tube axis of its effective part and the arrangement intervals of the apertures 6 to be included therein are respectively defined to HO and PVO, while the vertical length of the effective part in the position apart from the vertical axis including the tube axis by the distance X in the horizontal direction and the arrangement intervals of the apertures 6 to be included therein are defined to H and PV respectively, the formula PV/PVO=H/HO may be satisfied. Accordingly, while the picture vertical axis end of the phosphor screen being left in a shape of a circular arc, can be reduced unevenness generated in its outer peripheral line can be reduced to the negligible extent, thus unsightliness can be removed.

Abstract: PURPOSE:To relieve the stress due to thermal expansion and decrease local thermal deformation and then suppress color shift due to the thermal expansion of a shadow mask by providing an oblong slit stretching over two openings or more in the direction that is almost in parallel to the long direction of the shadow mask. CONSTITUTION:A shadow mask 2 is provided with a long slit 14 type permeation hole in the long direction. This oblong slit 14 hole is provided in the direction where it almost orthogonally intersects with a rectangular opening 7 that is long lengthwise along the same direction of the horizontal direction of the shadow mask and the width of the slit 14 is fully thinner or narrower than the thickness of the mask 2 or the horizontal width of the opening 7 to prevent an electron beam from passing through the slit. In addition, for the method of forming the slit 14 hole, form the curved surface of the mask and perforate it by mechanical punching and by using laser beam. As a result, the thermal deformation of the shadow mask is suppressed and the generation of beam landing error can effectively be suppressed.
