Abstract (en)
In an exhaust/sealing process for a cathode ray tube, the cathode-ray tube (10) is produced by exhausting air from the cathode-ray tube (10) with creation of a vacuum in the inside (15) and outside (16) of the cathode-ray tube (10). A production apparatus (11) for the cathode-ray tube (10) is so constructed by providing its exhaust/sealing unit for the cathode-ray tube (10) with means for creating a vacuum on a frit portion (8) of the cathode-ray tube (10) from outside. Accordingly, temperature of blackening process and the like can be lowered and a cathode-ray tube (10) whose weight is reduced can be produced. <IMAGE>
