摘要
A fluorescent display device including a cathode filament increased in mechanical strength and reduced in end cool. A 26% Re-W filament of 0.64 MG (corresponding to 0.64 mg in weight per 20 cm in length) exhibits an end cool as small as 4.2 mm on each of both sides thereof at a temperature of about 580° C. The end cool in a conventional W filament of the same diameter is increased to about 8 mm. The 26% Re-W filament is increased in mechanical strength by 50% as compared with the conventional W filament.
