摘要： In an electron gun, and a color cathode-ray tube and an image display device using the electron gun, each of two pairs of convergence electrodes is disposed in a focusing electrode for focusing three electron beams in a manner to pass the respective side beam of the three electron beams. Since an alternating current voltage synchronized with a deflection current is superposed to one of each pair of the convergence electrodes, such forces are exerted to the side beams as to separate the side beams from each other in the vicinity of the peripheral edge of a screen having a fluorescent body, so that the converging point of the electron beams is positioned on the screen. The focusing function of a main electron lens is weakened in the vicinity of the peripheral edge of the screen, whereby the electron beams are correctly focused.

摘要： The in-line type electron gun of this invention is formed so that a depression, which is formed at the lower voltage electrode face opposing to the higher electrode of the two electrodes for forming a common main focusing lens in the opposing gap thereof and has three lens holes for individual electron beams arrayed in-line at the bottom thereof, is formed so that the width in the direction perpendicular to the lens hole array direction is smaller at the central part in the lens hole array direction as compared with the other parts. Also the center lens hole of the three lens holes at the bottom of the depression is smaller in diameter than the other two. Accordingly, the focus voltages of the three beams passing through the three lens holes and the shapes of beam spots are made more uniform as compared with the prior art.
摘要翻译：本发明的直列式电子枪形成为形成在与两个电极的较高电极相对的低电压电极面的凹陷，用于在相对的间隙中形成公共的主聚焦透镜，并具有三个与其他部分相比，在透镜孔列排列方向的中央部分形成有在垂直于透镜孔排列方向的方向上的宽度较小的单个电子束的透镜孔。凹陷底部的三个透镜孔的中心透镜孔的直径也小于其他两个。因此，与现有技术相比，穿过三个透镜孔的三个光束的聚焦电压和光束点的形状更加均匀。
