Abstract: A display device having a cathode for emitting electrons and a permanent magnet. A two dimensional array of channels extends between opposite poles of the magnet. The magnet generates, in each channel, a magnetic field for forming electrons from the cathode into an electron beam. An electrode grid is disposed between the cathode and the magnet for controlling flow of electrons from the cathode into each channel. A screen has a phosphor coating having a plurality of groups of adjacent pixels facing the side of the magnet remote from the cathode. Each group corresponds to a different channel. A deflector sequentially addresses the electron beam from each channel to each pixel of the corresponding group.

Abstract: A color television picture tube of three in-line gun type wherein a ring-shaped ferrite permanent magnet or magnets are disposed around a neck portion of the tube, at least a pair of mutually-opposing pole pieces made of highly permeable magnetic material are provided within the tube neck portion as a part of the gun assembly so as to be magnetized by the ring magnet or magnets and to form an electron beam magnetic focusing lens system. In the picture tube, the pole pieces are each of a substantially elliptical cross section as viewed from a plane perpendicular to the tube axis, and spaces are provided between an inner wall of the tube neck portion and the pole pieces to accommodate support rods for gun assembling. There are selected to fall in particular ranges the ratio of the outer diameter to inner diameter of the permanent magnet, the ratio of the thickness to inner diameter thereof, the ratio of the thickness to gap length between the opposing pole pieces, and the ratio of the tube-axial length of the pole piece disposed on the side of a phosphor screen to the tube-axial length of the pole piece disposed on the side of cathode electrodes.

Abstract: There is disclosed an in-line type three-gun color picture tube with a couple of magnetic members inside its neck portion and a further magnet outside its neck portion. The respective magnetic members are provided with three through-holes permitting electron beams emitted from the electron guns to pass through and are disposed separately in a beam traveling path, so that the periphery of the through-holes of one of the magnetic members is magnetized in S pole and that of the other magnetic member is magnetized in N pole, and accordingly a focusing magnetic field is formed between the respective pairs of the through-holes which are opposite to each other. The magnetic pieces are disposed between the adjacent through-holes to intensify the magnetic field in the alignment of the through-holes which is weakened due to the presence of the through-holes, so that the focusing magnetic field in the alignment of the through-holes is compensated and accordingly the respective focusing magnetic fields become symmetrical with respect to their axes.

Abstract: A heating arrangement in which a focused electron beam under vacuum is deflected by electromagnetic means along an arc-shaped trajectory onto a predetermined target surface. A plurality of pole piece systems in the electromagnetic deflection means establish different magnetic fields. The field intensity of one pole piece system decreases from the inner edge of the beam to the outer edge thereof, in the plane of the trajectory. An auxiliary pole piece system with axis directed perpendicular to the plane of the trajectory has a sealed intensity which decreases from the outer edge of the beam to the inner edge thereof in the plane of the trajectory.
