Then, the bulb (4), which integrates the funnel part (2) and the neck part (3), is cleaned, and the phosphor is precipitated on the inner surface of the face part (1). A fluorescent film (5) is formed on the inner surface. Next, after drying the fluorescent film (5), the fluorescent film (5) is re-wetted, and a resin (lacquer) dissolved in an organic solvent is sprayed onto the fluorescent film (5).
As shown in the figure, a lacquer film (6) is formed on the fluorescent film (5). Furthermore, after removing excess lacquer adhering to the funnel part (2) and neck part (3) and drying the inner surface of the bulb (4), as shown in Fig. 5, the anode sealed to the funnel part (2) is removed. An internal conductive film (7) made of graphite or the like is formed from the button (not shown) to part of the neck (2). and,
As shown in Figure 6, the lacquer film (6) on the face (1)
) and a part of the internal conductive film (7) of the funnel part (2) are polymerized to form a metal back film (8) by aluminum vapor deposition. Thereafter, this bulb (4) is put into a firing furnace and fired, and the lacquer film (6) is thermally decomposed and removed.
As shown in the figure, the metal back film (8) is placed on the fluorescent film (6).
form. As shown in Fig. 8 below, an electron gun (9) is enclosed in the neck part (3) and evacuated, and after getter flash,
After the engineering process, explosion-proof treatment is performed such as wrapping a tensigon band (10) around the periphery of the face part (1), and graphite, etc. are applied to the outer peripheral surface of the funnel part (2) except near the anode button. An exterior conductive film (11) is formed to form a cathode ray tube as shown in FIG.

ス等のトラブルが発生していた。(Problems to be Solved by the Invention) As described above, conventional cathode ray tubes have an identification symbol (12) written on the side surface of the face portion (1) with heat-resistant ink or an adhesive tape (14) attached to the side surface of the face portion (1). Production is controlled individually on the production line based on the control slip (13), but the identification symbol (12) is manually entered and cannot be read automatically, and it is said that it will be rubbed off during handling. There are some drawbacks, and the management form (13) is adhesive tape (14).
), it has the disadvantage that it easily peels off at the slightest thing. Therefore, it has become impossible to automatically manage cathode ray tubes on the production line, leading to problems such as mixing of different types and counting errors.
