Description

X 선 관
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 한예를 나타내는 일부분을 절개한 단면도이다.
제2도는 본 발명과 종래기술의 특성을 비교하는 그라프로서, 전자 조사의 회수와 상대 X선 방사량의 관계를 나타내는 것이다.

Claims (8)

  1. 전자를 발생시키는 음극과, 발생된 상기 전자에 의해 생긴 충격을 받도록 된 전자 초점면을 가지고 있고 Mo의 특성을 X선을 주로 방사시키는 타켓트를 구비하고, 상기 전자 초점면이 티타늄, 산화칼륨, 산화규소 중 하나 이상을 포함하는 몰리브덴 합금으로 된 것을 특징으로 하는 X선 관.
  2. 제1항에 있어서, 타켓트가 전자 초점면을 지지하도록 된 지지기판을 포함하고, 상기 지지기판이 티타늄과 산화칼륨·산화규소 중 하나 이상을 함유하고 있는 몰리브덴 합금으로 된 것을 특징으로 하는 X선 관.
  3. 제1항에 있어서, 몰리브덴 합금이 티타늄과 탄소를 함유하고 있는 것을 특징으로 하는 X선 관.
  4. 제1항에 있어서, 몰리브덴 합금이 티타늄을 0.3 내지 4중량% 함유하고 있는 것을 특징으로 하는 X선 관.
  5. 제3항에 있어서, 몰리브덴 합금이 티타늄을 0.3 내지 4중량% 함유하고 탄소를 50내지 400ppm 함유하고 있는 것을 특징으로 하는 X선 관.
  6. 제1항에 있어서, 몰리브덴 합금이 0.01 내지 0.1중량%의 산화 칼륨과 0.02 내지 0.3중량%의 산화규소로 된 화합물을 함유하고 있는 것을 특징으로 하는 X선 관.
  7. 제1항에 있어서, 몰리브덴 합금이 티타늄을 0.3 내지 4중량% 함유하고, 산화칼륨을 0.01 내지 0.1중량% 포함하며, 산화규소를 0.02 내지 0.3중량% 함유하고 있는 것을 특징으로 하는 X선 관.
  8. 제1항에 있어서, 전자 초점면의 두께가 0.2mm 이상인 것을 특징으로 하는 X선 관.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
