Abstract: PURPOSE:To obtain a cathode-ray tube excellent in mechanical strength by setting specific relations between the radiuses of curvature inclusive of the vertical axis direction, horizontal axis direction and diagonal axis direction of the inner surface of the glass panel face part and the radiuses of curvature inclusive of the vertical axis direction and diagonal axis direction of the face part outer surface. CONSTITUTION:The captioned cathode-ray tube is so constituted that, when the radiuses of curvature in the vertical axis direction, horizontal axis direction and diagonal axis direction are Rv, RH and RD, there may be the relation Rv (RHo-RH) and (Rvo-Rv)>(RDo-RD). In this case, the mechanical strength can be improved as said above.

Abstract: PURPOSE:To obtain a picture tube having a shadow mask structure for reducing color shift due to thermal expansion by providing a shadow mask comprising a mask skirt section bent against non-effective face at the end of mask section, a frame for supporting said section and a heat reflection layer provided on said frame. CONSTITUTION:A shadow mask structure 15 is provided with a bent section 191 such that one end of frame 19 will cover the non-effective face of mask section where the skirt section 18 of mask section is welded directly or through a projection 20 to the inner wall of frame 19 while a heat reflection layer 22 is applied on the inner face of frame 19 facing with the mask skirt section 18. With such structure, radiation of heat produced by electron beam impinged against the mask skirt section 18 and around mask section is reflected to the mask side thus to rise temperature at the skirt section 18, whereby temperature difference between the center and circumference of mask section can be reduced to reduce color shift due to thermal expansion.

Abstract: PURPOSE:To concentrate three electron beams on almot one point on a screen by inserting a focusing member without mutually deflecting the central axes of the electron beam through holes of opposed electrodes that comprise relative principal focusing lenses. CONSTITUTION:When a focusing member 6 is inserted, the equipotential surface 7 of an electric field forms rotational symmetry for the central axis in the aperture of a final electrode 1, but it is located in the reverse direction with the central axis 5 with regard to the central axis 3 as the surface advances to the electron beam advance direction. Thus, the side electron beam is focueed in the direction of the central axis 5 and three electron beams are substantially deflected on a screen so as to be concentrated. However, since the focusing member 6 has the same central axis as the aperture central axis 3 of the final electrode 1, an electron lens is not distoted on the opposed surface of a principal electron lens and the electron beam focusing spot becomes a good circle and then a picture with good resolution can be obtained. In this case, it is important that the central axis 3 of the final electrode 1 should align the central axis of the focusing member, and the good electron beam focusing spot can be obtained by doing so.

Abstract translation: 目的：通过插入聚焦构件将三束电子束集中在一个点上，而不会通过包括相对主要聚焦透镜的相对电极的孔相互偏转电子束的中心轴。 构成：当插入聚焦构件6时，电场的等势面7对于最终电极1的孔径中的中心轴线形成旋转对称，但是它相对于中心轴线5位于与中心轴线5相反的方向 作为表面的中心轴3前进到电子束前进方向。 因此，侧电子束在中心轴线5的方向上聚焦，并且三个电子束在屏幕上基本上偏转以便集中。 然而，由于聚焦构件6具有与最终电极1的孔中心轴3相同的中心轴，所以电子透镜在主电子透镜的相对表面上不被分散，并且电子束聚焦点成为良好的圆， 那么可以获得具有良好分辨率的图像。 在这种情况下，重要的是最终电极1的中心轴3应该对准聚焦构件的中心轴线，并且可以通过这样做获得良好的电子束聚焦点。
