Title: Method for manufacturing flat discharge tube
Inventor: NAKAJIMA TAKETO
IPC: H01J9/40
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a flat discharge tube, capable of reducing breakage of a chip tube in the manufacturing process of the flat discharge tube. SOLUTION: At least the fixing part to fix a chip tube to both glass bases 14, 14 is formed into a double structure. To be concrete, after the inner end side of an inside chip tube 41 is inserted in a discharge space 1 7a and fixed, an outside chip tube 42 is inserted in the outer end side of the inside chip tube 41 so as to cover it, and under this condition the outside chip tube 42 is airtightly fixed to the glass base 14. Thereby, unlike the case where only a chip tube which is fine to the extent that it can be inserted in the discharge space 17 is fixed, strength in the fixing part of the chip tube is enhanced, and it does not get easily broken. Therefore, breakage of the chip tube can be reduced in the manufacturing process of the flat discharge tube 11, such as when putting the chip tube in and out and when connecting an intake and exhaust pipe 43 to the chip tube, for instance.
