摘要： PURPOSE:To enable the piercing of electron beam passing pores having a uniform shape and pore size by specifying the X-ray diffraction intensity ratio of the crystalline planes in the surface of an alloy sheet constituted of prescribed ratios of Ni and Fe and forming its structure into a nonrecrystallized one. CONSTITUTION:This stock for a shadow mask is formed with an Fe-Ni alloy sheet constituting of, by weight, 20 to 48% Ni, and the balance Fe. Furthermore, the X-ray diffraction intensity ratio of the crystalline planes {111}, {200}, {220} and {311} is regulated to 20 or larger (in the case the X-ray diffraction intensity of the face in which the X-ray diffraction intensity is the highest among respective faces, is regulated to 100). Then, the surface is formed into structure near the non-oriented state, and is wholly formed into a nonrecrystallized structure.

摘要： PURPOSE:To prevent oxidation of metallic part, by forming a separated silicon oxide membrane over the surface. CONSTITUTION:At an end of a cylindrical cathode tube 2 housing a heater 1 therein, a bass metal 3 is inserted, over which an oxide membrane 4 is formed. At the other end of the cathode tube 2, an inside cathode support 6 is fixed by laser welding through a strap 5. A portion of the inside cathode support 6 is fixed by laser welding to a strap 7 which is a cylindrical form concentric with the cathode tube 2, while the inside cathode support 6 itself is made of Kovar alloy. The surface of the support 6 is covered with SiO2 membrane 6a. Since oxidation of the metallic part of the electron tube can be prevented in such a way, the cost, the manufacture, and the performance of the electron tube are extensively improved.

摘要： PURPOSE:To prevent the deterioration of the color purity due to the thermal expansion of a shadow mask by constructing the shadow mask with a material composed mainly of Fe-Ni alloy and plating a Ni-P family alloy on the surface after annealing at a high temperature and press forming. CONSTITUTION:A color picture tube is constructed by providing the fluorescent screen 14, the electron gun 16, the shadow mask 15 and so on in an envelope consisting of the panel 11, the funnel 12 and the neck 13. The shadow mask 15 is made of a material composed mainly of Fe-Ni family alloy such as invar or the like, and it is formed to a specified curved surface by press forming after annealing in vacuum at a high temperature. Then the surface is plated with a Ni-P family alloy by electroless plating and so on, and the blackening process is applied to the surface to construct the shadow mask. Thus the mechanical strength of the shadow mask 15 is improved while keeping the low thermal expansion characteristics. thereby the deterioration of the color purity due to the heating and the vibration can be prevented effectively.

摘要： PURPOSE:To form parts having smooth surfaces with no warp at the edge part and the correct size with good productivity without performing barrel polishing or the like by press-processing a squeeze-processed spring material into a prescribed shape after a wire drawing process. CONSTITUTION:A spring material 22, which is about 0.32mm thick and 3.2mm wide, is formed so that its periphery may have no burr by squeeze-processing of a rod 21 of 14 Ni - 16 Cr stainless steel or the like manufactured by a wire drawing process. Next, said rod undergoes hardening treatment by heat treat ment at 450 deg.C for 30min followed by being press-processed into the prescribed shapes of a bulb spacer or the like for being formed into the parts 24 having no burr. Thereby, a polishing process for long hours comes to be unrequired while preventing the size change of a product due to polishing thus forming parts with good productivity.

摘要： PURPOSE:To form corrosion-resistant oxide film on a shadow mask by making iron composition ratio on the surface of shadow mask containing Fe and Ni as main component more excessive than initial iron composition through iron galvanization thereby forming gray black or black oxide film on the surface. CONSTITUTION:Iron composition ratio on the surface of shadow mask containing Fe and Ni as main component is made more excessive than initial iron composition through galvanization to form grey black or black oxide film on the surface. For example, a thin alloy plate containing 36% Ni and Fe as main component is made of fine holes of predetermined pattern through photoetching. Then vacuum annealing is performed under 1,200 deg.C then applied with leveller lightly to eliminate rumples produced during annealing and iron galvanized. Thereafter it is washed with water, neutralizd, alcohol substituted and dried then a flat mask is pressed and trichlane defat is performed to form an oxide film having thickness of 2mum in ambient gas of CO+CO2+O2 under the temperature of 570-600 deg.C.

摘要： PURPOSE:To improve moldability of curved surface and prevent deformation thereof by providing many pinholes on the metal plate mainly consisting of Fe- Ni system alloy, annealing it under the vacuum condition and thereafter molding it. CONSTITUTION:On the occasion of annealing a thin metal plate provided with many pinholes mainly consisting of Fe-Ni alloy, crystal grains grow as the annealing temperature increases but crystal grains in the surface little grow while crystal grains in the sectional area grow remarkably. Therefore, annealing is carried out under the vacuum condition with such pressure 7 as 10 Torr or less owing to exhaustion at a temperature of 1,000 deg.C or more. Thereby, strength at the yielding point can be lowered and high precision shadow mask without any deformation can be obtained.
