    摘要: A cathode-ray tube comprises a bulb formed by connecting a panel having a phosphor provided on the inner surface and a funnel having a conductive coating film provided on the inner wall, an electron gun housed in the neck portion of the funnel, and springs that are provided for a final electrode of the electron gun. The springs have contact portions to electrically contact the coating film on the funnel inner wall and the final electrode, in which the specific resistance value of the contact portions of the springs is determined to be greater than that of the graphite coating film contacting with the contact portions. As only one kind of conductive coating film need be applied, the production process can be simplified compared to the case for using plural kinds of coating films, and problems in connecting the junctions of the coating films can be also resolved. Furthermore, the maximum instantaneous current generated at a discharge inside the bulb can be reduced, and thus, malfunction or breakage of the circuit parts of a TV set can be prevented.

    摘要: A metal material is rolled to form a strip plate material having a middle part and thinner thickness-deviation portions on both sides of the middle part. After that, this strip plate material is bent and deformed in its width direction by roll forming, thus forming a bent and deformed portion in the middle part. The processing method includes a rolling step and a roll forming step, which enables the metal material to be processed economically using relatively simple steps. No annealing step is included and therefore an excellent final product is obtained. Particularly, the rolling step and the roll forming step are carried out successively, so that the roll forming can be carried out with high efficiency using processing heat generated in the rolling step. The bent and deformed portion is thick and the thickness-deviation portions are thinner, which contributes to the reduction in weight of a final product while the same strength as that of a conventional product is maintained.

    摘要: In a color cathode-ray tube with a shadow mask stretched and held by supporters while being provided with a tensile force, a member with a substantially L-shaped cross-section is used for each of the supporters, which is obtained by forming of a strip plate material having a middle part and thinner thickness-deviation portions on both sides of the middle part by rolling of a metal material; and then bending and deforming of the strip plate material in its width direction by roll forming to form a bent and deformed portion in the middle part. The supporter obtained by such a method can be reduced in weight while maintaining substantially the same strength as that of a conventional product, can be processed economically in relatively simple steps, and has less thickness variation. Therefore, an inexpensive color cathode-ray tube having stable qualities and causing less color unevenness can be provided.

    摘要: A cathode ray tube capable of reducing the doming amount and suppressing the occurrence of moire stripes at the same time with improved effects to suppress the occurrence of moire stripes even more is provided. The protruding portions 28a, 28b are protruding from the ends of the horizontal direction of the aperture to the inside of the aperture 27. With regard to the horizontal cross sections of the protruding portions 28a, 28b, the portions facing each other left and right via the aperture are formed to be asymmetrical to the center line 29 in order to reduce or block the incident electron beam. By forming the protruding portions 28a, 28b, the doming amount can be reduced and the occurrence of moire stripes can be suppressed at the same time. Furthermore, by forming the portions facing each other left and right of the protruding portions asymmetrically, the effects to suppress the occurrence of moire stripes can be improved even more.

    摘要: A cathode ray tube includes a pair of plate members (7) facing each other, a pair of supporters (14) adhered to the respective plate members (7) to support the plate members (7), and a shadow mask (6) adhered to the respective plate members (7) while being applied with tensile force. The supporters (14) have crank-shaped steps (15) formed to protrude toward the shadow mask (6). Thereby, an internal moment of a shadow mask structure can be decreased, and thus, displacement of the shadow mask (6) in the axial direction is suppressed even when the shadow mask (6) is expanded by heat generated by impact of electron beams, and q-value deviation is suppressed as well. Moreover, since the crank-shaped steps (15) are helpful in blocking a transverse clearance with a ferrous material, the magnetic properties can be improved.

    摘要: A cathode ray tube capable of reducing the doming amount and suppressing the occurrence of moire stripes at the same time, which also can prevent the so-called persimmon stone phenomenon from occurring, is provided. In the apertures, the protruding portions that are protruding from end faces in the horizontal direction of the apertures to the inside of the apertures are formed. The protruding portion in the aperture located on the right side of the phosphor surface from the vertical center line of the shadow mask is protruding in the direction toward the peripheral portion on the right side, while the protruding portion in the aperture located on the left side of the phosphor surface is protruding toward the peripheral portion on the left side. Accordingly, the doming amount can be reduced and the occurrence of moire stripes can be suppressed at the same time, while the persimmon stone phenomenon in which the beam spot of an electron beam on the phosphor surface is cut partially can be prevented from occurring.
