Claims (5)
- 전자빔을 발생하는 전자빔 발생부 및 상기 전자빔 발생부로부터 발생된 전자빔을 형광체 스크린 상에 포커스하는 주렌즈부를 구성하는 복수의 전극을 구비한 전자총구체,상기 전자총구체로부터 출사된 전자빔을 상기 형광체 스크린의 수평방향 및 수직방향으로 편향 주사하는 편향자계를 발생, 주사하는 편향요크, 및전자빔의 주사속도를 변조하는 속도변조 코일을 구비한 음극선관장치에 있어서,상기 전자총구체를 구성하는 적어도 1개의 전극은 전자빔 진행방향으로 배열된 적어도 2개의 전극부재를 접합함으로써 형성되고,제 1 전극부재는 이것에 인접하여 배치되는 제 2 전극부재에 접합되는 단면(端面)에 형성된 볼록부를 갖는 것을 특징으로 하는 음극선관장치.
- 제 1 항에 있어서,상기 볼록부는 상기 속도변조 코일에 의해 발생되는 자계가 전자빔에 대하여 작용하지 않는 영역에 형성된 것을 특징으로 하는 음극선관장치.
- 제 1 항에 있어서,상기 제 1 전극부재는 전자빔을 통과하는 전자빔 통과구멍을 갖고,상기 볼록부는 상기 전자빔 통과구멍의 중심축을 포함하는 수평방향의 단면(斷面)에 있어서, 상기 전자빔 통과구멍의 수평방향직경을 100%로 하였을 때, 상기 중심축을 중심으로서 상기 전자빔 통과구멍의 수평방향 직경의 50%의 영역을 피해 형성된 것을 특징으로 하는 음극선관장치.
- 제 1 항에 있어서,상기 제 2 전극부재는 상기 제 1 전극부재에 형성된 볼록부에 대응하여 상기 제 1 전극부재에 접합되는 단면(端面)에 형성된 볼록부를 갖는 것을 특징으로 하는 음극선관장치.
- 제 1 항에 있어서,적어도 2개의 전극부재를 접합함으로써 형성된 상기 전극은 상기 주렌즈부를 구성하는 전극인 것을 특징으로 하는 음극선관장치.
