Abstract
In a discharge tube manufacture line, electrode clamps are attached to both sides of an electrode lead except on a predetermined adhesion area to fix a glass bead. Then, a power section is driven to energize the area between the electrode clamps. The surface of the predetermined adhesion area is heated and oxidized. The glass bead is welded to the oxidized surface of the predetermined adhesion area.
Claims9
A method for manufacturing a discharge tube having a glass tube into which rare gas is put, a glass bead for sealing an end of said glass tube, and an electrode lead to be fixed to said glass bead, said method comprising:
- applying heat to only a predetermined adhesion area of said electrode lead by use of a heat application device to oxidize only a surface of said predetermined adhesion area of said electrode lead;
- and
- fixing said glass bead to said adhesion area of said electrode lead.
