发明名称 CATHODE-RAY TUBE WITH HIGH BRIGHTNESS
摘要 <p>PURPOSE:To prevent a picture quality from lowering due to leakage of liquid because of exfoliation of adhesives and due to air bubbles generated by ooze of liquid by providing a tank having inside a space for absorbing liquid pressure on the upper peripheral part of an airtight chamber coupled on the airtight chamber. CONSTITUTION:After injection of a coolant 5a, a tank 2d is mounted on an injection port 2b for being sealed, for example, by soldering. The inside of the tank 2d forms a vacant space connecting with an airtight chamber so that, when the coolant 5a in the airtight chamber is expanded, the expanded portion flows into the tank 2d so as to raise its liquid-level, while, when being cooled and contracted, flowing back again into the airtight chamber so as to maintain the liquid pressure in the airtight chamber constant. On the other hand, the air bubbles generated in the airtight chamber due to ooze or the like of the coolant 5a through the adhesives 3 are pushed up inside the tank 2d with the expansion of the coolant 5a without staying in front of the panel so as not to disturb the picture.</p>
