IPC: H01J31/12
Filed: 1982-03-12
Abstract: PURPOSE:To improve the accuracy of each positioning without yielding the thermal expansion of an electrode with small rigidity by arranging elongation adjusting spacers with the appropriate thermal coefficient of expansion, while allowing them to be adjacent to said electrode. CONSTITUTION:Thermal expansion in a heating and burning process for an electrode 6 with small rigidity can be adjusted by an elongation adjusting spacer 14 since it is affected by a connecting spacer 3 and the elongation adjusting spacer 14 that put said electrode therebetween. Therefore, the coefficient of thermal expansion of the elongation adjusting spacer 14 is set to a value where the coefficient of thermal expansion of the electrode 6 with small rigidity is equal to that of electrode 5 with a large rigidity. Further, the same effect can be anticipated also when the elongation adjusting spacer 14 is arranged so as to make contact with the electrode 5. Hereby, it is possible to perform inter- electrode positioning and positioning against a cathode and a phosphor body with high accuracy and ease.
