によって構成されている。(4) is a metal band wrapped around the panel skirt (1b). Note that there is a neck at the rear that houses an electron gun, but it is omitted in this figure. In this example, the side wall interposed between the panel face (la) and the neck is constituted by a panel skirt (]b) and a funnel (2a).

力が作用している。Next, the operation will be explained. When creating a vacuum inside a CRT, compressive stress is generated on most of the CRT surface, but
Tensile stress is generated in the shaded area in the figure, that is, in the front periphery and part of the side surfaces of the CRT. Figure 7 shows CRT 1.
This is a drawing of the main part of /4. Glass exhibits high strength under compressive stress, but low strength under tensile stress.In particular, the outer surface is susceptible to minute scratches during manufacturing, which is the main reason for the decrease in tensile strength. Therefore, in glass CRTs, care is taken to avoid generating tensile stress on the CRT surface as much as possible. However, with a nearly round CRT...
J, Tensile stress is still acting on the shaded area & 1 and 2 shown in Fig. 7.

問題点があった。Conventional CRTs are made entirely of glass as described above, so it is necessary to reduce stress by increasing the thickness of the glass. The problem with the T-shaped glass was that the thickness of the glass plate was always 1゛ thicker, increasing the number of seals.

Also, the metal sidewall above! ! ! ! In a CRT, there is a problem in that high stress is generated in the frit glass (3) that seals the side wall (2) and the ε panel face (1a).This invention solves the problem mentioned above.

The figure is a partial cross-sectional view, and the same or corresponding parts as in the conventional model ω are designated by the same reference numerals, and their explanation will be omitted. In the figure, (10) is the peripheral edge of the banel frame L (1a) and this peripheral edge C=the metal body forming the connected side wall, and in this example, the entire side wall (2) is also shown in Figure 6. Even the funnel (2a) shown in the conventional example is completely formed of metal. The central part of the panel face (1a), that is, the part on which the image is projected, is made of glass such as H8602 material from ENAJ (E1 Electronics Industry Association), and the metal body (l c) is made of the above-mentioned glass. Carbon mesh, for example, is used because it has a coefficient of thermal expansion close to , and generates less gas in a vacuum. Also, the panel face (l a)

An explosion-proof front glass (8) is provided through the front glass (8), but this front glass (6) prevents the gas part of the Banel Fuse (1a) from scattering forward even if the CRT is destroyed. E for prevention 4! It is additive. For example, in a small CRT, the -W surface glass (6) may not be provided in uM7 because the mechanical strength at the time of destruction is small. (
7) is a plate-shaped rib that is cut, for example, by welding, in the axial direction of the metal body (IC) on the inner circumference of the side wall portion of the metal body (1c) through which the electron beam does not pass. The ribs (7) are made of the same material as the metal body (1c), and are arranged in a plurality with predetermined gaps. Although not shown, the outer surface of the metal body (1, c) is entirely covered with a coating for insulation.

The stress distribution state on the surface of R1' is as shown in Figure 2, compressive stress is distributed on the entire surface of the glass part of Banelf 5-th (I a ), and the surface of Banelf, L-th (12 m) is A tensile stress is generated from the peripheral edge to a part of the side wall (2). Since the part that generates this tensile stress is made of metal, two crystal shields with allowable stress can be created, and the plate thickness can therefore be made thinner.

重量は軽減される。Furthermore, since a rib (7) was provided on the inner circumference of the side wall of the metal body (1c) through which the electric f-beam does not pass, the metal body (1e
> is reinforced, and the deformation and stress on the side wall of the metal body (1c) is reduced, so if stress and deformation are allowed to the same level as before, the plate thickness of the metal body (1C) should be made thinner. The weight of the metal body (LC) can be reduced without changing the external shape.

It may be installed along the circumferential direction of the side wall portion of the metal body (IC), or it may be installed along the axial direction and the circumferential direction of the side wall portion of the metal body (IC) at the same time. Furthermore, it may be provided along a diagonal direction.

), or the height of each rib (7) may be changed as shown in Figure 5. The shape may be freely changed depending on the stress distribution, and the number of ribs (7) may be changed. The spacing is not limited either, and the ribs (7) may be concentrated in areas where the stress distribution is high. In this case, the side wall portion of the metal body (1C) can be reinforced more effectively.

軽量なＣＲＴが得られるという効果が得られる。As described above, according to the present invention, the peripheral edge of the panel face and at least a part of the side wall connected to this peripheral edge are formed of a metal body that does not contain glass in the thickness direction, and the metal body is made of a metal body that does not contain glass through which electron beams do not pass. The structure has ribs installed on the inner periphery of the side walls, so the external dimensions of the CRT remain the same as before.
The advantage is that a lightweight CRT can be obtained.
