ELECTRODE FORMING METHOD, ELECTRODE FORMING DEVICE, AND EXTERNAL ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method of forming an electrode without a pointed part which may cause abnormal electric discharge. SOLUTION: A masking member 7 having an opening 8 for regulating the forming width B of an external electrode 2 is disposed under a screen print mask 4 comprising a mesh 3 allowing the penetration of an electrode material 5. The electrode material 5 is slid on the mesh 3, and a glass tube 1 is moved in the same direction as the electrode material 5 while being rotated along the lower face of the masking member 7. The electrode material 5 is thereby applied to the surface of the glass tube 1 through the mesh 3 and baked afterward. COPYRIGHT: (C)2008,JPO&INPIT
