随着我国四化建设的发展,应用电视在钢铁、化工、纺织、铁道、医疗及机床等部门得到了越来越广泛的应用。应用电视中的主要元件之一是视象管,提高它的质量,增加它的品种势在必行。 SF-1211即一英寸硫化锑靶面管内带固定座标分离网结构的视象管,就是为此目的而试制的。 SF-1211电子枪结构和工作原理完全与SF-1210、SF-25等同,电性能指标也相似,唯独靶面增加一个固定座标。如图1照片所示: With the development of the four modernizations in our country, applied television has been applied more and more widely in the departments of steel, chemical, textile, railway, medical treatment and machine tool. One of the major components in the application of televisions is the video tube. To improve its quality and increase its variety is imperative. SF-1211 is one inch of antimony sulfide target tube with fixed coordinate separation network structure of the video tube, is for this purpose and trial production. SF-1211 electron gun structure and working principle completely SF-1210, SF-25 equivalent, electrical performance is also similar, except for the target surface to add a fixed coordinates.
