수상관의 전자빔 제어회로Electron Beam Control Circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

도면에는 수상기중 본 발명에 중요한 부분만이 도시되어 있다. 수상관(1)은 신호원(2)으로부터 캐소드의 비디오신호 R,G 및 B로 구동된다. 수상관(1)은 코트라스트의 조절을 위한 제어전압이 인가될 수 있는 그리드 G1를 갖는다. 그리드 G3는 전자빔의 포거싱을 위한 전압 UF을 인가하는데 사용된다. 애노드 A에는 고전압 UH이 인가된다. 그리드 G2에는 고정직류 전압 Ug2이 저항(3)을 통해 인가된다.Only the parts of the receiver important to the present invention are shown. The water pipe 1 is driven from the signal source 2 to the video signals R, G and B of the cathode. The water pipe 1 has a grid G1 to which a control voltage for adjusting the coat last can be applied. Grid G3 is used to apply the voltage U F for fogging of the electron beam. The high voltage U H is applied to the anode A. The fixed DC voltage Ug 2 is applied to the grid G2 via the resistor 3.
