Description

음극 선관용 전자총Cathode ray gun

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

제1도는 일반적인 음극선관의 입단면도,1 is a cross-sectional view of a typical cathode ray tube,

제3도는 본 발명에 따른 전자총의 일부절제 측면도,3 is a side view of a partial ablation of the electron gun according to the present invention;

제4도는 제3도에 도시된 쉴드컵을 확대하여 도시한 사시도.4 is an enlarged perspective view of the shield cup shown in FIG.

Claims (3)

삼극관부를 이루는 캐소오드, 제어전극 및 스크린전극과, 주렌즈계를 이루는 복수개의 포커스 및 애노우드 전극과, 상기 애노우드 전극과 결합되는 쉴드컵을 구비하여서된 음극선관용 전자총에 있어서, 상기 쉴드컵(16) 내면의 각 전자빔통과공(16a)주위에 포커스 보정용 자계발생수단(20)을 설치하여, 편향요오크(16)의 불균일 자계에 의한 전자빔의 왜곡을 상기 포커스 보정용 자게발생수단으로 보상하도록 한 것을 특징으로 하는 음극선관용 전자총.In the electron gun for cathode ray tube comprising a cathode, a control electrode and a screen electrode forming a triode, a plurality of focus and anode electrodes forming a main lens system, and a shield cup coupled to the anode, the shield cup (16) The focus correction magnetic field generating means 20 is provided around each electron beam passing hole 16a on the inner surface to compensate for the distortion of the electron beam caused by the non-uniform magnetic field of the deflection yoke 16 with the focus correcting magnetic generating means. Electron gun for cathode ray tube, characterized in that. 제1항에 있어서, 상기 쉴드컵(16)의 내면에 설치된 자계발생수단(20)이 쉴드컵(16)의 내면의 전자빔통과공(16a)주위에 수직방향으로 상호 대향되게 설치된 제1전자석(21)과 수평방향으로 상호 대향되게 설치된 제2전자석(22)을 구비하여 된 것을 특징으로 하는 음극선관용 전자총.According to claim 1, wherein the magnetic field generating means 20 provided on the inner surface of the shield cup 16, the first electromagnet installed opposite to each other in the vertical direction around the electron beam through hole (16a) of the inner surface of the shield cup ( 21) and a second electromagnet 22 provided opposite to each other in the horizontal direction. 제2항에 있어서, 상기 제1전자석(21)과 제2전자석(22)에는 편향요크의 수평·수직 편향코일에 동기하는 소정의 전위를 인가하여 된 것을 특징으로 하는 음극선관용 전자총.3. An electron gun for cathode ray tubes according to claim 2, wherein a predetermined electric potential is applied to said first electromagnet (21) and said second electromagnet (22) in synchronization with the horizontal and vertical deflection coils of the deflection yoke. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
