【発明の詳細な説明】
本発明は、数字や記号等を表示するための表示管に用い
る扁平型パルプに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flat pulp used for display tubes for displaying numbers, symbols, etc.
従来の扁平型表示管用パルプの多くは、第１図に示すよ
うな構造をしていた。このパルプは、板ガラスを素材粉
とし、これを所定の大きさに切断した後、黒鉛や金属製
成形型によって熱開成型加工して造られていた。Most conventional pulps for flat display tubes had a structure as shown in FIG. This pulp was made by using plate glass as a raw material powder, cutting it into a predetermined size, and then heat-opening it using a graphite or metal mold.
しかしながら、従来のこうした製法によるパルプの欠点

、及び熱衝撃強度検査不良等の要因となっていた。However, the disadvantage of pulp manufactured by conventional manufacturing methods is that when trying to improve the flatness of the display window fr (Sla) shown in Figure 1, the heating temperature of the display window is generally kept as low as possible, and the peripheral area is In order to deform the pulp by heating, the glass wall thickness of the side surface portion 2a was significantly thinned.This thinning of the side surface portion 2a reduces the mechanical strength of the pulp and the display tube using the pulp. This was the cause of crack accidents during the secondary processing of pulp, the sealing and exhaust process of display tubes, and failures in thermal shock strength tests.

が困難でコスト高になると云う欠点を有してい九。Figure 2 shows one way to solve these drawbacks.
This is found in Japanese Patent Application Laid-Open No. 47-45371. In this case, the display window l has the flatness of a glass plate itself, and is significantly superior to the hot-formed pulp in terms of visibility of the display. However, the side surface 2 forming the recess for use as the pulp of the display tube is composed of another glass piece 2b and the low melting point glass 3. Therefore,
Completed display tube mount (board assembly) for the glass piece 2b
4, and painting the surrounding area with low-melting point powdered glass paste requires a large amount of man-hours, making it difficult to convert into a building and increasing costs.9.

闘の二種類のカラス細片２ｂ及び２０を製造した。It is formed by welding a composite body made by integrating a glass powder and a low melting point glass powder by powder molding onto a piece of plate glass that will become the display window. Therefore, the small piece 2 of the lath is attached to the board assembly 4, which requires careful attention as described above.
This not only eliminates the assembling work and the application work of low-melting glass paste in step b, but also prevents contamination of display elements due to binder decomposition gas during the encapsulation process and contamination of products, equipment, and jigs and tools due to scattering of low-point glass powder. (Preferably grade B) was cut into lengths of 87W and width of 20-20cm. The plate glass piece was washed, and a conductive tin oxide film (conductive coating) 5 was deposited on its surface to form a display window 1 for a fluorescent display tube. Next, another plate glass with a thickness of 1.8 m ('') was first cut into 80 m (width) and 300 m (length) and 20 m (width) and 300 knits (length). Approximately 80 x 18 x 300 pieces, laminated with a mixture of pine resin,
And after making it into a rectangular parallelepiped of about 20x18x3001I+s,
Cut at 3 fin intervals perpendicular to the longitudinal direction with a tire wheel cutting machine, 80X18X3M, and 20X
It was made into a composite glass piece of 18 x 311 m. Next, the crow pieces are immersed in an organic solvent to dissolve the pitch and pine resin mixture, and the crow pieces are separated into individual crow pieces, i.e., 3 mm wide and 1.8 mm thick.
Connection, length SOW and width 3ss1 thickness 1.8M, length 20
Two types of crow strips 2b and 20 were produced.

成形した。Next, the two J-lase strips 2b and 2C were assembled into a square frame shape, and a low melting point powdered glass was applied to the surface thereof under pressure. Here, as the low melting point glass powder, LS-0206 glass sold by Nippon Electric Glass Co., Ltd., which had passed through a 150 mesh sieve, was used. In order to improve the moldability of the powdered glass, a weight ratio of 1.5 was added in advance.
A fluid powder (fine) was mixed therein, and this was placed in a frame-shaped powder mold (female mold) together with the plate glass strips, and a male mold was combined and pressure molded at a pressure of 300 kyfiys2.

A garden with a rectangular frame of 3 (width). The frame body is placed on the surface of the display window 1 on which the conductive coating 5 is applied, and is sequentially fed into a belt-type electric furnace and heated at 395°C ± 3°C for 10 minutes to sinter and display. It stuck to the window. In this case, the heating rate is very consistent; up to 300°C, the organic material is heated at a rate of 15°C per minute, and from 300°C to 395°C, it is slowly heated at a rate of 5°C or less per minute. (Ida was completely removed.
