VERFAHREN UND VORRICHTUNG ZUR VERBESSERUNG EINES VAKUUMS IN EINEM GASDICHTEN BEHAELTER

摘要

In a known process for influencing the vacuum in a gas-tight container, in particular a glass bulb containing functional parts provided with feed lines that pass through the container wall, the functional parts are heated during evacuation, with the result that substances emanating from the functional parts and contaminating the vacuum are also aspirated. In order to improve the vacuum, the functional parts are heated by laser radiation during evacuation.
