Abstract
PURPOSE: To prevent the deterioration of insulation resistance, prevent the occurrence of cracks and prevent the deterioration ot be caused by temperature changes at the time of heating and cooling, by impregnating sponge-like cement mainly made of silicic soda with methyl-chdrogen-siloxane.
CONSTITUTION: Both ends of quartx-tube-type transparent container 30 in which halogen substance, inert gas and filament are sealed, are pressure-sealed and sealed part 31 is formed. Lead lines 32 are connected to these parts. Electricity supplies 33 respectively connected to these lead lines are of cylindrical form and a part of each forms connection part 34. Cylindrical mouthpiece 35 made of insulating ceramic is provided on the circumferential surface of each electricity supply 33. The portion between mouthpiece 35 and the end part of the sealed part is filled with as adhesive cement 36, which is mainly made of silicic soda with average particle diameter about 150 and a small quantity of Al2O3, MgO and also water glass as solidifier, and in which open spaces 37 are provided
