Abstract
PURPOSE:To properly remove remaining impure gases and adsorbed impure gases from in a tube and improve the tube characteristics by evacuating an unsealed glow discharge tube, filling the tube with a rare gas, conducting a discharge in the tube, reevacuating the tube, and filling the tube with a seal-in gas. CONSTITUTION:A lighting tube of which the electrode or stem is coated with La, Ce, or the like as an activating agnet is evacuated to remove adsorbed impure gases, and filled with a rare gas such as Ar before subjected to a discharge, preferably a glow discharge. This discharge removes the adsorbed gases, decomposes the stain or the like on the electrode surface, and removes the impure gases. After re-removing the impure gases by evacuation, the tube is filled with a seal-in gas such as Ar under a predetermined pressure and then sealed. This method ensures good removal of remaining impure gases and adsorbed impure gases from in the tube, and provides a glow-discharge tube prevented from deterioration during long use period.
