Abstract
PURPOSE: To provide a bulb producing method, by which the replacement of the gas in bulb is finised to allow the bulb to be separated from supply and discharge conduits and by which the gas under high pressure is then blown into the supply and discharge conduits to remove foreign substances therefrom, thus preventing the downstream valves from being contaminated.
