摘要： An electron gun for a color picture tube has beam generators for generating three electron beams and directing them toward the fluorescent screen along three paths which are parallel with each other on the same plane, and at least one pair of electrode surfaces each having three apertures centered with the three paths for forming independent main lenses so as to focus the electron beams on the fluorescent screen, the electrode surfaces being spaced apart from each other. Provided for the electrode surface are cylindrical shield members centered with the apertures and extending from the apertures in opposition to the opposing electrode surface. Outer ones of the cylindrical shield members have each an end surface inclined with respect to the center axis of the aperture so as to form inclined electric fields effective to converge the outer beams to one point to which the central beam converges.

摘要： An electron gun for a color picture tube consists of a triode that generates a plurality of electron beams and a main lens which focuses and converges the electron beams. The main lens can be divided into two types, i.e., a pair of bi-potential focusing electron lenses and a combination of the bi-potential focusing electron lens and a uni-potential focusing electron lens. The electrodes constituting the main lens have apertures for permitting the transmission of a plurality of electron beams. The center axes of apertures are deviated toward the center axis of the embodiment of electron gun away from the axes of initial paths of the electron beams emitted from the triode.

摘要： An electron gun for a television camera tube comprises a cathode for emission of electrons, a first grid disposed subsequently to the cathode and having a first aperture supplied with a positive voltage relative to the cathode, a second grid disposed subsequently to the first grid and having a second aperture supplied with a higher positive voltage than that supplied to the first grid, and an intermediate grid interposed between the first and second grids and having a hole. The intermediate grid forms a divergent electron lens near the first aperture between the first and second grids. An electron beam having passed through the first aperture is once diverged by the divergent electron lens to form a crossover at an axial position of the gun which is remote from the first grid and at which the potential on the beam axis is high, whereby broadening of the width of the velocity distribution of extracted electrons can be suppressed to a minimum and the amount of beam current passing through the second aperture can be increased.
