Abstract

PURPOSE:To enable voltage to be impressed on the electrode G5 without any troublesome problem related to complexity of manufacturing process, reliability and so on, by composing the second electrode with four electrode parts deflecting an electron beam and forming the leads connecting the first electrode to the third one through between said electrode parts. CONSTITUTION:The electrodes G3-G5 are formed, for example, by vacuum evaporating or plating metal such as nickel, chrome or the like on the inner face of a glass bulb and then cutting it in the predetermined pattern. The four electrode parts H+, V+, H- and V- composing the electrode G4 have the predetermined angular clearance of DELTA degree in circular direction between each other, wherein the leads L0 for connecting the electrode G3 to G5 are formed. Thereby, it becomes unnecessary, for example, to do works upon the glass bulb such as to make holes in the glass bulb in order to impress voltage on the electrode G5 and thus the impression of voltage upon the electrode G5 is possible without any troublesome problem related to complexity of manufacturing process, reliability and so on.

Although it is possible to apply a predetermined voltage to the G5 via a stem bin and a contactor ring, there is a problem of pressure being applied to the overlapped G5.

However, since it processes glass bulbs, there were problems in terms of process complexity and reliability.
