摘要： A deflection system for a cathode-ray tube (16) including a horizontal deflection coil (2), a magnetic core (4), and a vertical deflection coil (3) toroidally wound on the magnetic core (4). The vertical deflection coil (3) has a plurality of superimposed winding layers arranged with respect to a vertical axis of the deflection system with at least one of the layers of the vertical deflection coil (3) being disposed asymmetrically with respect to the vertical axis or disposed symmetrically with respect to the vertical axis and having winding portions delimiting at least one gap along an extent thereof at a position other than the vertical axis (6). In this manner, an induced voltage in the at least one of the layers is substantially equal to an induced voltage in each of another of the layers at least in the region of the vertical axis (6), whereby ringing is substantially prevented.

摘要： PURPOSE:To release the shifting of STC(where the electron beam is not focused at one point.) by bringing the ratio of the distance between the center of the outside electron beam pass hole and the tube axis and the facing distance between the main lens forming electrodes into specific range. CONSTITUTION:The electrodes 3a, 3b for forming the electrostatic main lens of an inline integrated electron gun are made of magnetic member while a permanent magnet 1 is located at the neck section to form a magnetic main lens between facing planar sections 2a, 2b. Electron beam pass holes 20-22 are formed with distance (s) at said sections 2a, 2b. Assuming the facing distance at said sections 2a, 2b is Lg, the value of (s) should be set to satisfy 0.5s

摘要： PURPOSE:To perform the rough adjustment of convergence easily by providing a magnetic board having long and short diameters in a field generating means for generating a beam focusing field between magnetic yokes then rotating it. CONSTITUTION:The electron beam from a cathode 2 is focused by the first and third grids 3, 4 then accelerated by a magnetic yoke 5 to reach to a fluorescent face 14. While the magnetic yoke 5 will absorb the flux from a permanent magnet 8 to produce a focusing field at the gap section to form a magnetic main lens. Furthermore a magnetic board 19 having long and short diameters and perpendicular with the axis is provided at the fluorescent face side of the permanent magnet 8, then it is rotated around the axis to fix in random direction thus to perform the rough adjustment of convergence. Consequently the convergence can be adjusted easily without requiring the adjustment of four pole field generator 15.

摘要： PURPOSE:To prevent drifting phenomena of an electron beam and to devise an improvement of a convergence shifting by surrounding an electromagnetic focusing space of an electron beam with a magnetic shielding body made of a high conductive material. CONSTITUTION:In an electromagnetic focusing space between magnetic yokes 5 installed oppositely facing, a magnetic shield 13 formed as a cylindrical shape with a conductive magnetic body such as for example permalloid is provided so as to surround an entity of cylindrical magnet bodies 8 and permanent magnets 9. By making in this manner, the magnetic shield 13 is together with forming a parallel magnetic branch route for a magnetic circuit consisting of magnetic yokes 5, cylindrical magnetic bodies 8 and their intermediate gaps and also shielding a leakage flux from side surfaces of permanent magnets 9, omitting a leakage to a deflecting magnetic field and a magnetic circuit of high accuracy can be formed. Also an electrical field due to a charged potential upon an insulator surface is shielded and a drifting of an electron beam can be prevented.

摘要： PURPOSE:To realize miniaturization of a projection television without deteriorating the brilliancy by disposing the deflection coils inside the cathode-ray tube and the core outside the tube and by establishing the potential of the internal conductive film within the active range of the deflecting field lower than the anode potential. CONSTITUTION:After winding the vertical deflection coils 54 and the horizontal deflection coils 55 in spiral form, the entire surfaces are covered by glass material in the vacuum for the purpose of preventing gas generation and improving the anti-potential characteristics between wires. Moreover, the length in Z direction is made short, at the same time the entire body is shifted towards the phosphor surface 3 side and the deflection center is shifted towards the front side. Outside the neck tube 7, a ferrite core 51 is disposed to improve the sensitivity of the deflecting magnetic field. By means of such a structure, the effective F number can be made small as the deflecting system shields the light flux passing through the lens 4 very little. Also, the anode potential is applied to the phosphor surface 3 and the 4th electrode 15 of an electron gun through the introducing entrance 10, and the deflection sensitivity is improved, as the internal conductive film 8, the nesa film 9 and the 3rd electrode 14 are applied with the lower potential than the anode potential.

摘要： PURPOSE:To improve the intensity and the contrast of a photoamplifier by forming a substance having good electric conductivity and light reflectivity in an insular shape and inserting instead of an opaque layer a layer surrounded by an insulator having good light absorbance at the periphery. CONSTITUTION:The layer of the structure that a substance having good electric conductivity and good light reflectivity such as, for example, an aluminum film is formed in an insular shape and the periphery is surrounded by an insulating having good light absorbance is inserted instead of an opaque layer. An optical image reproduced on a photoconductive film 3 is sampled by an electric conductor 7, and is tansmitted as information to an electroluminescence EL layer. The periphery of the conductor 7 is surrounded by an insulator 8, and the conductors 7 are maintained in an electrically insulated state from each other. In other words, the information of the photoconductive film 3 which is contacted with the conductor 7 is small in an electric resistance of the conductor 7, and can be completely transmitted to the EL layer. Therefore, in this manner, the intensity and the contrast of the titled device can be improved.
