ELECTRON GUN AND METHOD FOR MANUFACTURING ELECTRODE OF ELECTRON GUN

WIPO Patent Application WO/2002/027750

A1

An electron gun of a cathode-ray tube and a method for manufacturing the electrode of an electron gun. The electrode of an electron gun is formed into a thin plate (7) where a metallic part (N) formed from one side of a metallic material (1) by shaving is continuous with the metallic material. The thin plate may be formed by coining. In such a way a thin plate part can be formed by a single machining regardless of the thickness of the metallic material. When a hole for passing an electron beam is made in the thin plate part of such an electrode, a highly precise electron gun having a micro hole for passing an electron beam can be produced while maintaining the mechanical strength of the electrode.
