摘要： A color cathode ray tube having an improved electron gun, includes a quadrupole lens consisting of an independent static electrode having a static voltage applied thereto and a dynamic electrode which is disposed opposite to the independent electrode and having a dynamic voltage applied thereto. A dynamic strong quadrupole lens effect is obtained by applying a modulation voltage or parabola voltage to the dynamic electrode. When electron-beam-passing-apertures in electrodes of a main lens are enlarged, each axial distance between the axes of three electron-beam-passing-apertures of the static electrode opposite to the dynamic electrode in the strong quadrupole lens forming electrodes is offset and the sizes of the opposite side electron-beam-passing-apertures are increased by the offset axial distance. Thus, a change in the convergence and spherical abberations resulting when a modulated voltage is applied can be minimized, thereby improving resolution characteristics in the peripheral areas of a screen and convergence characteristics.
摘要翻译：具有改进的电子枪的彩色阴极射线管包括由施加有静电压的独立静电极组成的四极透镜和与独立电极相对设置且具有施加于其上的动态电压的动态电极。通过向动态电极施加调制电压或抛物线电压，获得动态强四极杆透镜效应。当主透镜的电极中的电子束通过孔径扩大时，在强四极透镜形成电极中与动态电极相反的静电电极的三个电子束通过孔的轴线之间的每个轴向距离被偏移并且相对侧的电子束通过孔的尺寸增加偏移的轴向距离。因此，可以使施加调制电压时产生的会聚和球面衰减的变化最小化，从而提高了屏幕的周边区域的分辨率特性和会聚特性。

摘要： An electron gun has a plurality of grid electrodes for focusing electron beams radiated from cathodes, at least one of said grid electrodes having a cylindrical body containing a plate member. The plate member has a central electron-beam-passing-aperture and two side apertures. At least one of the two side apertures is contoured by a first circular arc and a second circular arc, two first vertical lines respectively extending outward from either ends of the first circular arc, two second vertical lines respectively extending outward from either ends of the second circular arc, and two connecting lines respectively connecting each of outer ends of the first vertical lines to each of outer ends of the second vertical lines. The electron gun improves the degree of freedom in controlling shapes of beam spots focused on a phosphor screen, thereby heightening the resolution of the cathode ray tube.
