Abstract

PURPOSE:To provide a display tube having high springiness and a thermal expansion coefficient close to glass and having an electronic part whose light reflectance is small. CONSTITUTION:This metallic material is composed of Ni of 36 to 47weight%, Ti of 2.0 to 2.6weight% and a residual part of Fe. Springiness is higher than 426 alloy, and is almost equal to SUS304. A thermal expansion coefficient is smaller than the SUS304, and is close to glass or the 426 alloy. In the metallic material, a surface is blackened by heat treatment in a range of 350 to 600 deg.C. When an electronic part in a fluorescent character display tube is composed of this metallic material, this is heated and blackened in a manufacturing process, and light reflectance is reduced. Even if external light strikes on the fluorescent character display tube at display time, visibility of display of the fluorescent character display tube is not reduced. A negative electrode support body to apply proper tensile force to an internally attached control electrode becoming familiar with a glass substrate or a filament becoming familiar with the glass substrate, can be composed of a single part.

なお、完全に酸化したＴｉは白色になる。The manufacturing process of the fluorescent display tube includes several firing steps. For example, in the sealing process for assembling the envelope, the entire envelope is heated at about 350 ° C. At least the surface of the metal material of each of the embodiments is blackened by the heat treatment. It is considered that this is because the heat treatment turns Ti and Ni in the material into oxygen-deficient oxides TiO 2 and NiO 2 , which appear black.
Note that completely oxidized Ti becomes white.

It can be seen that the reflectance is much lower than that of No. 4. That is, when the cathode support of the fluorescent display tube is formed by using the metal material of the present embodiment, the cathode support is blackened by the heat treatment in the manufacturing process and the reflectance of light becomes low. Therefore, even if external light strikes the fluorescent display tube during display, strong light does not return to the observer side, and the visibility of the display of the fluorescent display tube is not adversely affected.
