使用する。But xenon emission for photography strobe flashlight? 12TFF, which uses cesium, an electron-emitting substance, in its sintered cathode has a low decomposition temperature, so it is difficult to seal the sintered cathode with a quartz tube, which has a high softening point. A borosilicate glass tube is used as the tube.

使用したキセノンランプに比べ諸性性が劣る。When using a borosilicate glass tube as described above, ions generated by discharge collide with the inner wall of the tube, causing impurity gas (C
0, H2O, etc.), so even if the glass tube is treated as a gas in a high-temperature vacuum during production, its properties are inferior to xenon lamps using quartz tubes.

A transparent insulating film (for example, SiO2 film) is formed on the inner and outer surfaces except for the cathode sealing portion 1, and 6 is a Nesa film for a trigger.

膜５の形成によってガラス管球の融点が上界する。The tube 1 is made by cutting a borosilicate glass tube 1' into the required size as shown in FIGS. 2 and 3, and inserting it into a container 11 with one end (the cathode-sealed portion of 3 to 5III11) remaining.
The 5102 membrane 5 is formed on the inner and outer surfaces by immersing it in the 3i alcoholate solution 12, pulling it up, drying it, and then firing it at an appropriate temperature. As the glass tube 1', for example, S

結陰極３の封止を行うことができる。However, the cathode sealing portion does not have the insulating film 5 formed thereon and is melted at a lower temperature than other portions, so that the sintered cathode 3 can be sealed without decomposing the cesium.

ることができる。With this structure, since a transparent insulating film 5 such as 5RO2 is formed on the inner and outer surfaces of the borosilicate glass bulb 1 other than the cathode sealing part, cesium is used as an electron-emissive substance in the sintered cathode 3. However, when sealing the cathode 3 at the end of the borosilicate glass tube 1, the cathode is bead-processed and the heat treatment temperature for sealing can be kept at a low temperature, preventing evaporation of cesium, etc. be done. Further, the insulating film 5 on the inner surface prevents gas generation due to discharge. Furthermore, an insulating film 5 on the outer surface
serves as a base film for the Nesa film (5Oo2) and is effective in improving adhesion and lowering resistance. This insulating film 5 can be formed by a simple method of immersing it in a 3i alcoholate solution 12.

It is possible to prevent the generation of impure gas when ions generated by discharge collide with the inner wall of the tube, improving durability and starting characteristics, and also being effective in preventing blackening. Furthermore, the insulating film on the outer surface serves as a base for the NESA film, and is effective in improving the adhesion and lowering the resistance of the NESA film. Furthermore, handling of glass tubes as gas (
Vacuum heating) is important in the manufacturing process of xenon tubes, but if an insulating film is formed immediately after handling with gas, moisture absorption will be prevented and maintenance management will be easier.
