Filament for fluorescent display device |
摘要 |
A filament core wire capable of being mounted while having tension at a predetermined level applied thereto without an expensive anchor and without applying unnecessary tension thereto. The filament core wire is provided at a part thereof with spring and welded sections. The sections each are covered with a heat-decomposable block element made of acrylic resin or the like. Also, the core wire has a carbonate deposited thereon. The core wire is mounted on a mounting position by removing the block element from the welded section of the wire arranged on the fixing position by heating and then welding the welded section to a fixing spot of the fixing position. Then, block element is removed from the spring section by heating. This permits the filament core wire to be stretchedly arranged at the mounting position while keeping tension applied to the core wire to provide it with elasticity.
