摘要： An electron gun assembly comprises a cathode capable of emitting electron beams and at least first and second grid electrodes having electron beam holes through which the electron beams emitted from the cathode are passed individually and capable of controlling the electron beams. The first and/or second grid electrode is a superposed structure formed of different metallic materials superposed in the advancing direction of the electron beams. The grid electrode includes a FenullNinullCo alloy located around the electron beam holes.

摘要： An electric power source assembly supplies the focusing electrodes of a color cathode ray tube. Such a color cathode ray tube normally includes three electron guns arranged in a line transverse to their beam path. The focusing voltages supplied the focusing electrodes associated with the three guns are independently adjusted to compensate for beam distortion caused by positional differences in gun location. The D.C. and A.C. voltage to the static and or dynamic electrodes is independently controlled to improve beam focus of each individual gun.

摘要： An electron gun which has an assembly precision improved by the reduction of deformation of an electrode during assembly as well as good focusing performance due to the elimination of positional deviation of electron beams. The electron gun comprises a composite electrode including at least two electrode elements united together and a plurality of electrodes sequentially arrayed along a single axis at predetermined intervals. In the electron gun, opposed faces of the electrode elements of the composite electrode are perpendicular to the axis and the opposed faces are provided with projections which serve to constitute the composite electrode when the projections are united together in opposed relationship to each other.

摘要： A color cathode ray tube includes a panel portion having a phosphor screen on its inside surface and suspending a shadow mask hanged closely spaced from the phosphor screen, a neck portion for housing an electron gun, and a funnel portion for connecting the panel portion to the neck portion. The electron gun is composed of a first plurality of grid electrodes spaced specified distances apart and arranged axially in a specified order, respectively, and fixed by insulating rods embedding the first plurality of grid electrodes therein, including a cup-shaped first grid electrode having a second plurality of in-line electron beam apertures in a bottom thereof and having the second plurality of cathodes incorporated therein. The cup-shaped first grid electrode is embedded in the insulating rods through metal tabs fixed thereto, and a thermal expansion coefficient T1 of the metal tabs and a thermal expansion coefficient T2 of the cup-shaped first grid electrode satisfy the following inequality, T1>T2.
