Abstract
PURPOSE: To secure adhesion of the fluorescent substance, the filament and others after mounting them and thus to avoid the breakdown of the exhaustion tube by providing the sintered glass body of a ring form at the joint between the display tube substrate and the exhaustion tube and then heating up the glass body to adhere the substrate and the exhaustion tube together.
CONSTITUTION: Both display substrate 2 to which the parts necessary for display such as the fluorescent substrate, the filament and others are attached and formed glass cover 4 on which low fusing point sealing glass 3 is coated and printed at the fixed place are set to jig 1 made of the heat-resistance special steel. Then exhaustion tube 5 is provided at the fixed part on the back of substrate 2, and ring-shaped glass tablet 7 which is formed by the low fusing point glass powder similar to glass 3 through the compression formed sintering is supplied to joint 6. Then jig 1 is put into the neutral atmosphere furnace of 450°C to be heated about 10 minutes. Thus, substrate 2 and cover 4 are sealed together, and at the same time tube 5 is chipped off through exhaustion after close adhesion of substrate 2 and tube 5.
