Abstract

PURPOSE:To reduce the influence of in-tube discharge by forming a resistor layer on the surface opposite to the inner tag of a bulb spacer or a funnel getter support which is installed on an electron gun. CONSTITUTION:Onto the surface opposite to the inner tag 6 on the funnel inside of a bulb spacer 4, Al2O3 layer 8 is applied in 50-100mu, and the evaporation film 9 of Ni-Cr alloy is applied through evaporation, and a resistor film is formed. The resistance value between an anode button and a convergence cup is 600-800OMEGA at this time. Therefore, even if discharge occurs between the terminal electrode of the electron gun and other electrode, the voltage drop is increased by the resistor layer, and the power in discharge can be reduced, and the bad influence to the cathode and the parts in the tube can be reduced.
