Abstract

〈목적〉 수직 방향의 코마 수차 및 R 빔과 B 빔과의 교차 잘못된 수렴 쌍방을 양호하게 보정할 수 있는 컬러 음극선관용 전자 편향 요크를 제공한다. 〈구성〉 코일 보빈(3)의 후부 전자총측의 플랜지부(3a)에 상측 및 하측의 그 자형의 코어(4a),(4b)를 설치한다. 코어(4a),(4b)에 상측 및 하측에서 동일 방향의 자속을 발생하는 보조 코일(14a),(14b)와 상측 및 하측에서 역 방향의 자속을 발생하는 보조 코일(15a),(15b)을 감는다. 보조 코일(14a),(14b)의 접속점에 보조 코일(15a),(15b)의 일단을 접속하고 다른단을 보조 코일(14a),(14b)에 병렬 접속된 가변 저항에 접속해서 보조 코일(15a),(15b)에 의한 보조량을 조정한다.OBJECT Provided is an electron deflection yoke for a color cathode ray tube that can correct both coma aberration in the vertical direction and cross wrong convergence between an R beam and a B beam. <Configuration> The upper and lower magnetic cores 4a and 4b are provided in the flange portion 3a on the rear side electron gun side of the coil bobbin 3. Auxiliary coils 14a and 14b which generate magnetic flux in the same direction on the cores 4a and 4b in the upper and lower sides, and auxiliary coils 15a and 15b which generate magnetic flux in the reverse direction in the upper and lower sides. Wind One end of the auxiliary coils 15a and 15b is connected to the connection points of the auxiliary coils 14a and 14b and the other end is connected to a variable resistor connected in parallel to the auxiliary coils 14a and 14b. The auxiliary amount by 15a) and 15b is adjusted.
