GLASS PRESSURE-VESSEL FOR A CATHODE RAY TUBE

摘要

A glass pressure vessel for a cathode ray tube comprising a concave glass and a rectangular glass back-plate to be bound to the concave glass with glass Frit, satisfies the following inequalities, 1000 W/(Lt2)>/=2.8 t1>/=0.8 t2 where t1 (mm) is the thickness of the concave glass, L (mm) and t2 (mm) are the length of the short side and the thickness of the back-plate, respectively, and W (mm) is a bond width in which the flange portion of the concave glass and the back-plate are bonded together.
