    摘要:  導電性碍子を使用する加速管において、表面のドーパント濃度が不均一となるため、導電性碍子の表面抵抗が不均一になることがあるが、この場合でも、内面垂直方向の電位分布を円周方向によらず一定に保つことが課題である。 導電性碍子加速管の内面に円周状の溝を数段設け、溝の内部に沿って金属をメタライズする。加速管表面の特定の部分の抵抗が周囲と違う場合でも、加速管内面のメタライズ領域の電位は一定になるので、加速管内面の垂直方向電位分布を、円周方向によらずほぼ同一に保つことができる。この結果、中心軸上を通過する電子線に横方向の力が働かないとともに、電位勾配もほぼ一定に保つことができ収差を小さくすることが可能である。

    摘要翻译: 在使用导电绝缘体的加速管中,表面上的掺杂剂密度变得不均匀,这可能使导电绝缘体的表面电阻不均匀。 本发明的问题在于,即使在这种情况下,也可以在垂直方向上保持内表面上的电位分布不受圆周方向的影响。 在导电性绝缘子加速管的内表面上设置有多个圆形槽,沿着槽的内侧金属化。 由于加速管的内表面的特定部分的电阻与周围表面不同,因此加速管的内表面上的金属化区域的电位是均匀的,因此垂直方向上的电位分布 加速管的内表面可以保持在大致相同的电位而不考虑圆周方向。 结果,没有作用在通过中心轴的电子束上的水平力,电位梯度也保持几乎恒定,并且可以实现像差减小。

    摘要: A display tube comprises an electron source (10), a module (20) provided with a guidance cavity (25R, 25G, 25B) for guiding electrons emitted by the electron source (10) to an exit aperture (27R, 27G, 27B) of the guidance cavity (25R, 25G, 25B), and beam-shaping means (30) for forming an electron beam (EBR, EBG, EBB) from guided electrons leaving the exit aperture (27R, 27G, 27B). The electron beam (EBR, EBG, EBB) travels towards a display screen (3). The beam-shaping means (30) are arranged to constitute, in operation, an electron lens for shaping the electron beam (EBR, EBG, EBB) so as to compensate for unwanted distortions of the shape of the electron beam (EBR, EBG, EBB) between the exit aperture (27R, 27G, 27B) and the display screen (3). These distortions are, for example, caused by the magnetic field of deflection means (2). The image quality of the display tube is improved.

    摘要: An electron gun (10) as for a cathode ray tube includes a plurality of electrodes biased at different potentials to electrostatically shape and focus the one or more electron beams produced thereby. A dynamic focus grid (G6) is driven by a substantial ac voltage signal at the horizontal line rate, which signal is undesirably coupled through parasitic capacitance to an intermediate grid (G7) located between the dynamic focus grid (G6) and the gun anode (G8). A resistive biasing network includes a high value resistance to divide the anode potential to develop bias potential for the intermediate grid and a capacitance to ac couple the intermediate grip to ground potential. The resistance and/or capacitance are formed in a plural layer ceramic circuit. The ceramic circuit may be located in the tube neck on or with the electron gun.

    摘要: An electron gun structure (22) comprises at least one additional electrode (Gs) arranged along an equipotential surface formed between a focusing electrode (G3) and an anode electrode (G4), which form a main lens. For no deflection, a predetermined voltage applied to the additional electrode (Gs) corresponds to the potential of the equipotential surface in which the additional electrode (Gs) is arranged. For deflection, the convergence in vertical directions (Y) is different from that in horizontal directions (X) as the value of (Vs-Vf) / (Eb-Vf) varies with the increase in deflection of the electron beam, where (Vf) is the voltage applied to the focusing electrode (G3), Eb is the voltage applied to the anode electrode (G4), and Vs is the voltage applied to the additional electrode (Gs).

    摘要: The invention relates to a cathode ray tube having an electron gun (10) which is provided with a so-called Aberration Reducing Triode (15). The ART (15) pre-focuses the electron beam (EB) such that outer rays in the pre-focus lens (20) are near the center of the electron beam (EB) in the main lens (30). Spherical aberrations are reduced, thereby. However, under given circumstances, moirepattems can appear in the image formed on the display screen (50), especially in parts of the image having a low brightness. According to the present invention, the pre-focus lens (20) in the ART (15) is arranged such that the pre-focusing effect thereof is reduced when the beam current of the electron beam (EB) is below a predetermined threshold beam current. This reduces or eliminates the moirepattems.

    摘要: An electron gun has a pluraltiy 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.

    摘要: Electron-optical device having two elongate emitting regions arranged symmetrically with respect to a longitudinal axis for producing two electron beams having an elongate cross section. By means of electron grids, the two beams are focused at the same point of an electron target arranged transversely to the longitudinal axis and having a short central axis and a long central axis. The elongate emitting regions have their smallest cross section parallel to the scanning direction of a device, cooperating with the electron-optical device, for scanning a target arranged transversely to the longitudinal axis.
