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.

摘要： The invention provides efficient means for dissipating deleterious charge build-up in the glass neck portion of a color cathode ray tube employing an in-line plural beam electron gun assembly. In one embodiment, the invention is comprised of two longitudinal stripes of electrical conductive material oppositely applied on the neck substantially over both narrow sides of the gun assembly. Connective conductors join the stripes to the grounded funnel coating to provide for dissipation of the charge. In another embodiment, the longitudinal stripes are joined by two band-like layers encompassing inter-electrode spacings of the gun assembly.
