Abstract

본 발명은 형상이 개선된 음극선관용 전면유리에 관한 것으로, 내면 측면부(2)의 형상을 이루는데 있어서, 일정한 한점을 기준으로 해서 그 두께를 조절하되, 이 기준점인 B점의 위치는 블렌드 반경(3) 센터 하단부와 브레이크 라인 사이의 어느한 지점에 놓이도록 하고 그 위치는 t2가 t1t21.3t1지점에 놓이도록 하며 기준점(B)에 대한 블렌드 반경(3)의 접선기울기는 상호연결되고, 기준점(B)에서 실에지 두께(t1)과 연결되도록 하는 기준을 두어 음극선관용 전면유리의 내면 측면부가 일정한 강도를 유지할 수 있도록 한 것이다The present invention relates to a windshield for the cathode ray tube with improved shape, in forming the shape of the inner side surface portion 2, the thickness is adjusted based on a constant point, the position of the point B, which is the reference point is the blend radius ( 3) at any point between the lower center of the center and the brake line and its position so that t 2 is at point t 1 t 2 1.3t 1 and the tangential slope of the blend radius (3) to the reference point (B) is mutually The inner side surface of the cathode ray tube windshield is provided with a reference to be connected to the thread edge thickness t 1 at the reference point B so as to maintain a constant strength.

Description
