    • A unidirectional double deflection type cathode ray tube comprises an evacuated envelope, a target at one end of the envelope, an electron gun at the other end of the envelope for emitting an electron beam, main deflection means positioned between the electron gun and the target for deflecting the electron beam in one direction, an arcuate lens electrode device curved about the deflection center of the electron beam caused by the main deflection means, the lens aperture electrode device being provided with a plurality of lens apertures equally spaced apart in the direction of the scanning of the electron beam. Further provided is an auxiliary deflection means co-operating with and synchronized with the main deflection means for further deflecting the beam by a length equal to the pitch of the projection of the lens apertures the electron beam being thereby deflected to the positions of respective lens apertures.
    • 单向双折射型阴极射线管包括真空外壳,外壳一端的靶,用于发射电子束的外壳另一端的电子枪,位于电子枪与靶之间的主偏转装置 沿一个方向偏转电子束,围绕由主偏转装置引起的电子束的偏转中心弯曲的弧形透镜电极装置,透镜孔径电极装置设置有沿着方向等距间隔开的多个透镜孔 扫描电子束。 进一步提供的是与主偏转装置协同操作并与主偏转装置同步的辅助偏转装置,用于进一步使光束偏转等于透镜孔的投影的间距的长度,从而将电子束偏转到各个透镜孔的位置 。
