摘要： A cathode, a control electrode, and an accelerating electrode are formed in this order, and electron beam passing holes for passing an electron beam emitted from the cathode are provided in the control electrode and the accelerating electrode, respectively. A concave portion is formed on a surface of the control electrode on a side of the accelerating electrode, and a convex portion is formed on a surface of the accelerating electrode on a side of the control electrode. This allows an actual gap between the control electrode and the accelerating electrode on a periphery of the electron beam passing holes to be reduced, and thus a voltage to be applied to the accelerating electrode can be reduced. Further, while the voltage of the accelerating electrode is suppressed, the electron beam passing hole of the control electrode can be reduced in diameter, and thus a beam spot formed on a phosphor screen can be reduced in diameter.

摘要翻译： 依次形成阴极，控制电极和加速电极，分别在控制电极和加速电极中设置用于使从阴极发射的电子束通过的电子束通过孔。 在加速电极侧的控制电极的表面上形成有凹部，在加速电极的控制电极一侧的表面形成有凸部。 这允许减小电子束通孔周边的控制电极和加速电极之间的实际间隙，从而可以减小对加速电极施加的电压。 此外，在加速电极的电压被抑制的同时，可以减小控制电极的电子束通过孔的直径，从而能够减小形成在荧光屏上的光斑直径。

摘要： Color display device with a deflection-dependent distance between outer beams. A color display device comprises an electron gun, a display screen and a color selection electrode as well as a deflection means. The distance between the electron beams is dynamically varied, whereby the distance in the deflection space decreases as the beams are deflected in at least one direction. The reduction of the distance enables the distance between the color selection electrode and the display screen to be increased in that direction. As a result, the curvature of the color selection electrode is increased, which has a positive effect on the strength and the doming and microphonic properties of the color selection electrode.

摘要翻译： 彩色显示装置与外梁之间具有偏转依赖距离。 彩色显示装置包括电子枪，显示屏和选色电极以及偏转装置。 电子束之间的距离是动态变化的，由此当光束沿至少一个方向偏转时，偏转空间中的距离减小。 距离的减小使得选色电极和显示屏之间的距离在该方向上增加。 结果，选色电极的曲率增加，这对选色电极的强度和隆起和麦克风性质具有积极的影响。

The outer portion of each of the leg portions includes a first multilayer winding portion having heating wires wound spirally in plural layers, and the inner portion of each of the leg portions includes a second multilayer winding portion having heating wires wound spirally in plural layers. The number of turns per unit length in the first multilayer winding portion is smaller than that in the second multilayer winding portion.

摘要： According to an electron gun for a cathode ray tube of the present invention, in an electron gun for a cathode ray tube which performs correction of an electron beam by applying a correction magnetic field to an electrode of the electron gun, at least a part of an electrode in a region which is affected by the correction magnetic field comprises a bellows-like electrode. According to the arrangement, a high frequency correction magnetic field from outside the cathode ray tube penetrates into the electrode more so that a preferable electron beam correction effect can be attained without disturbing the magnetic field.
