摘要： An auxiliary grid which is formed with one or more elongated slits through which pass electron beams is disposed in a prefocusing system in a cathode-ray tube, and a dynamic voltage which varies in level with increase in horizontal deflection angle is applied to the auxiliary grid so that axial asymmetry of the prefocusing system can be increased with increase in the horizontal deflection angle. As a consequence, the beam spot can be maintained substantially in the form of a true circle not only at the center of the screen but also at the portions adjacent to the peripheries thereof. Thus, the resolution at the portions adjacent to the peripheries of the screen can be improved and consequently high-quality images can be represented over the whole surface of the screen.

摘要： A reinforcing electrode plate having at least one electron-beam through-hole that passes an electron beam is connected to at least one of a focusing electrode and a final accelerating electrode at its opening portion. Supporting portions of the reinforcing electrode plate are formed so as to project further outside than the opening portion or the peripheral face of the electrode, thus fixing the reinforcing electrode plate to an insulating support. Therefore, the deformation of the focusing electrode or the final accelerating electrode that occurs in assembling a main lens of an electron gun used for a color cathode-ray tube is prevented, thus decreasing the variation in property of the electron gun. Additionally, by adjusting the shape or the like of an opening through which an electron beam passes in the reinforcing electrode plate, a focusing power of the main lens can be adjusted in the horizontal direction and in the vertical direction.
摘要翻译：具有至少一个通过电子束的电子束通孔的加强电极板在其开口部连接到聚焦电极和最终加速电极中的至少一个。加强电极板的支撑部分形成为比电极的开口部分或外周面更外侧突出，从而将加强电极板固定到绝缘支撑件上。因此，防止了在组装用于彩色阴极射线管的电子枪的主透镜时发生的聚焦电极或最终加速电极的变形，从而降低了电子枪的性能变化。此外，通过调整电子束通过加强电极板的开口的形状等，可以在水平方向和垂直方向上调节主透镜的聚焦能力。
