摘要： PROBLEM TO BE SOLVED: To improve the productivity by uniformly cooling the peripheral part of the bottom part of a mold for press shaping a glass panel for a cathode ray tube. SOLUTION: The peripheral part of the mold bottom part is uniformly cooled by forming the shape of the cross section of at least a part close to the mold bottom part of each supporting leg 4, provided at the bottom part of the mold 2 for shaping a molded body 1, into a nearly wing profile, and then preventing the flow of cooling air from being peeled by the supporting leg when the cooling air flows to the peripheral part along with the bottom face of the mold after the cooling air blown out from a nozzle provided at the lower part of the mold collides with the center of the mold bottom part so that a hind part of each supporting leg, whereinto the cooling air does not flow, is avoided.

摘要： PROBLEM TO BE SOLVED: To improve productivity by efficiently cooling a peripheral part while suppressing cooling of the central part of a face section in a pressure molding manufacturing process step for glass panels for cathode ray tubes. SOLUTION: A shielding plate 3 is disposed below a duct 4 for cooling a molding 1 and the cooling air blown off from the duct 4 is blown to this shielding plate 3 and is introduced into the peripheral part 7 of the face section 5, by which the portions exclusive of the portions protected by the shielding plate 3 are preferentially cooled while the cooling of the portions protected by the shielding plate 3 of the face section is suppressed.

摘要： PROBLEM TO BE SOLVED: To reduce weight by forming a body part into such a funnel shape as to be continuously changed from an opening end to a yoke part, providing diagonal recesses on diagonal parts of the body part, and thinning the body part near a sealing part and a panel skirt part. SOLUTION: A body part 6 is formed into such a funnel shape that its inner and outer surfaces are continuously changed from a rectangular opening end to a yoke part. Recesses 11 are provided on diagonal parts of the body part 6 along the diagonal direction. Relative low vacuum stress generated near the sealing part of the outer surface of the diagonal part is slightly increased by specifying the curved surface shapes of the diagonal parts of the body part 6 of a glass funnel 2, while, relative high tensile vacuum stress generated near the sealing part of the centers of four sides and having the relative large peak is reduced by dispersion of stress. Accordingly, the effect for balancing the distribution of vacuum stress can be obtained, and a glass valve having its reduced weight can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a safe and high reliable glass funnel which has a structure enhancing rigidity of a body section and realizes reduction of the depth dimension and weight reduction without increasing stress, and a cathode-ray tube using the glass funnel. SOLUTION: Arch face sections 12 and a dome-shaped section 13 form the body section 3 of the glass funnel for a cathode-ray tube 2. An arch-shaped ridge line section 8, both ends of which are near the corner section of an opening end section, forms the arch face section 12 nearly perpendicular to the opening end section at least on the long side of the body section 3, so that the stress occurring at the body section travels along the arch-shaped ridge line section 8 to the corner high in rigidity of the opening end section.

摘要： PROBLEM TO BE SOLVED: To provide a glass funnel capable of being shortened in depth and reduced in weight without increasing stress by forming a body section out of arch face sections, erected nearly vertically to an opening end section and provided with arch-shaped ridge line sections having both ends near the corner sections of the opening end section and a dome-shaped section. SOLUTION: A body section 3 is provided with ridge line sections 8 on the sides of an opening end section and arch face sections 12 nearly perpendicular to an opening end face 11. The end sections of the ridge line sections 8 are located at the corner sections of the opening end section, and the arch face section 12 is inclined against the opening end face 11 by about 5-15 deg., thereby the rigidity of the body section 3 as a vacuum envelope is improved, the stresses can be reduced, and this cathode-ray tube can be made lightweight. The angle θ between tangential lines at the contact point between a blended R section on the ridge line section at the center of each side and the arch face section 12 and at the contact point between the blended R section and a dome-shaped section is preferably set to 90 deg.
