摘要： A metal/ferrite laminate magnet (100) has perforations forming apertures (125) in the magnet (100). The magnet is formed of outside metal plates (105) surrounding a sandwich of two layers of ferrite material (115). The outside metal plates (105) allow the perforations (125) to be made in the magnet (100) before sintering of the magnet (100) and maintain the alignment of the holes (125) during sintering. The metal plates (105) also provide the magnet (100) with mechanical robustness and rigidity and prevent cracking occurring between adjacent apertures (125).

摘要： A deflection yoke (10) for a cathode ray tube improves assembly and productivity and enables effective control of magnetic field corrections during device processing. The deflection yoke includes a horizontal deflection coil (12) located next to the outer circumference of a funnel (4) to generate a horizontal magnetic field, and a vertical deflection coil (14) installed at the outer circumference of the funnel to generate a vertical deflection magnetic field. The vertical deflection coil is insulated from the horizontal deflection coil. A ferrite core (16) is located close to the vertical deflection coil to reduce the loss in the magnetic force generated from the horizontal and vertical deflection coils, and to enhance their magnetic efficiency. A correction unit (20) is spaced apart from the horizontal deflection coil by a predetermined distance to correct a geometric distortion of the vertical and the horizontal deflection magnetic fields that is generated due to the vertical and horizontal deflection coils.

摘要： A display device comprises a screen. A back plate is sealed to the screen to form an evacuated chamber. Area cathode means is disposed between the back plate and the screen. A permanent magnet is disposed between the cathode and the screen. A two dimensional array of rows and columns of channels extends between opposite poles of the magnet for receiving electrons from the cathode means. An anode phosphor layer is disposed between screen and the magnet for receiving electrons from the channels. Grid electrode means between the area cathode means and the magnet controls flow of electrons from the cathode means into the channels. Anode means between the magnet and the anode phosphor layer controls flow of electrons from the channels towards the screen. In one such arrangement, the screen comprises a layer of a plastic material. In another such arrangement a plurality of spacers are disposed between the screen and the magnet. Each spacer has an elongate body having a larger cross sectional area at one end of the spacer tapering to a smaller cross sectional area at the other end of the spacer. In another such arrangement, and a plurality of spacers are disposed between the magnet and cathode. The spacers are located in recesses formed in the grid electrode means. In yet another such arrangement, the cathode means comprises a back-plate and a silica glass substrate peripherally sealed to the back-plate to produce a chamber. A gas is contained in the chamber. A layer of photo-sensitive material is disposed on the surface of the substrate external to the chamber. A cathode phosphor layer is disposed between the back plate and the substrate. A pair of electrodes facing each other from opposite sides of the chamber energises the gas to generate a plasma for exciting the phosphor to generate light energy to produce electron emissions from the photo-cathode.

摘要： A magnetic ray tube comprises in a glass envelope 1 which consists of a display window 2, a cone 3 and a neck 4, an electron gun 5 in said neck 4 for generating an electron beam 6. The electron beam 6 is focused by a magnetic focusing lens 12 consisting of two non-identical magnets 13 and 14 which are assembled at the neck 4. The magnetic field of said magnetic focusing lens is essentially asymmetrical with respect to the centre of the lens and the magnetic fields of the magnets attenuate each other more strongly in the space where the electron beam is deflected than on the other side of the focusing lens.
