た。That is, the following steps are generally taken to seal a flash discharge tube. 3A, B, and C are diagrams for explaining the sealing procedure of a general flash discharge tube. In FIG. 3A, an electrode rod 6 made of tungsten is heated with a mixed gas of propane and oxygen or hydrogen and oxygen while rotating in an inert gas atmosphere, and a sealing glass 11 is formed on the surface of the electrode rod 6. Glass-wrapped and processed into glass-wrapped electrodes. On the other hand, the third
In FIG. B, the quartz glass container 1 is heated with the mixed gas while being rotated, a sealing glass 11 is applied to the end of the quartz glass container 1, and the glass-wrapped quartz glass container is processed. Subsequently, in FIG. 3C, the glass-wound electrode shown in FIG. 3A and the glass-wound quartz glass container shown in FIG. 3 are heated and connected with the mixed gas (311C).
. In the flash discharge tube thus obtained, the electrode lead rod 6 led out was easily broken from the tip 12. This is because, in FIG. 3A, when wrapping the sealing glass around the electrode lead rod made of tungsten,
Since the electrode lead is heated to over 1700℃,
This is because the electrode lead rod recrystallizes and becomes brittle.Furthermore, in the process of connecting the glass-wound electrode and the glass-wound quartz glass container in Figure 3C, heating is repeated and recrystallization is promoted. This is because they become even more brittle and easily break.According to experiments, the electrode lead rods of about 20% of flash discharge tubes broke due to a single drop impact of 200G.
