摘要： A color cathode ray tube includes a three beam inline electron gun; a deflection device for performing deflection and self-convergence; a static beam convergence device having permanent magnets for generating a magnetic field adjustable to converge three electron beams at a central portion of a phosphor screen; and a dynamic convergence device having coreless electromagnetic coils for generating a magnetic field adjustable to converge three electron beams at peripheral portions of the phosphor screen. The dynamic beam convergence device includes a spiral coil conductor formed on a non-magnetic film. The dynamic beam convergence device also includes two cylindrical holder members having large and small diameters, respectively, made of an insulating material, which are held in such a manner as to be coaxial and overlapped on each other; and a coil member including a plurality of printed coils for generating magnetic fields having an even number of poles contained in a flexible film, the coil member being disposed between the two cylindrical holder members having large and small diameters respectively; wherein a plurality of the printed coils are stacked in the flexible film in such a manner as to be insulated from each other; and printed coils adjacent to each other and having the same diameter are electrically connected to each other in the flexible film.

摘要： A cathode structure for a magnetron representative of a self-oscillation type microwave electron tube comprises a pair of opposite end shields for supporting both ends of a filament helically wound in an axial direction, and a getter fixed on at least an upper end shield positioned on the side of a terminal from which a microwave oscillation output is produced. The upper end shield is concaved with respect to a lower end shield, and the getter provided on the upper end shield is also concaved so as to be closely fitted over substantially the entirety of an outer surface of the upper end shield. Preferably, the getter provided on the upper end shield has an upright annular wall of a central burring hole. Thus, the improved cathode structure is immune to deformation and suitable for cleaning and welding, thereby ensuring improved lifetime stability and high fabrication efficiency.
