摘要： Raster demodulation apparatus for a raster-scanned cathode ray tube display comprises control means (400) for varying the shape of at least one scanned electron beam spot (661-663) in a direction perpendicular to scan lines of the raster. The control means (400) comprises an electromagnet (700) for mounting on the neck of the cathode ray tube. The magnet (700) has eight pole pieces (720-790) spaced around the neck of the cathode ray tube (210). A winding (710) passes around each of the pole pieces (720-790) in succession in opposite directions so that, when an electrical current (I) is passed through the winding, adjacent pole pieces (720-790) around the neck of the cathode ray tube have different magnetic polarity to generate, within the neck of the cathode ray tube (210), a magnetic field in which magnetic lines of force (680) pass through the or each electron beam (661-663) only in a direction parallel to the scan lines of the raster.

摘要： An electron beam focusing device with two dynamic windings is provided for apparatus such as cathode ray tubes . The focusing device (12) includes a static field generator (10) and two (13),(14) coupled coils windings mounted axially adjacent or overlapped along the beam axis. The static field generator can be a permanent magnet and the first and second windings can be superimposed at the axial center of the static field of the magnet. Alternatively, the static field generator can have a winding in a magnetically permeable shield structure (11) with a gap (22) for concentrating the static field at an axial end of the focusing device, the first and second windings being superimposed on one another adjacent the gap and outside the shield.

摘要： A landing correction coil (6) is provided at the rear of a horizontal deflection coil (5) of a deflection yoke or at a position where it is closely coupled with the horizontal deflection coil (5). The landing correction coil (6) is fixed so as to generate a magnetic field perpendicular to the axis of a CRT.
Moreover, the landing correction coil (6) is connected so that a current flowing in a horizontal deflection coil (5) may flow in the landing correction coil (6).
Furthermore, the landing correction coil (6) is connected to an adjustment coil (7) for adjusting the current flowing therein.
A varying means is provided in the adjustment coil (7) and the polarity and amplitude of the current flowing in the landing correction coil (6) is adjusted by the varying means. This causes the magnetic field distribution for scanning an electron beam of a CRT to be changed and enables a landing characteristic to be adjusted electrically.

摘要： An electromagnetic device for magnetically focusing and deflecting an electron beam in a television camera tube comprising a vertical deflection coil (11), a horizontal deflection coil (12), a ferromagnetic coil (17) and focusing coil (16). Electrostatic screens (13 and 14) are respectively provided on the inner side of the vertical deflection coil and the outer side of the horizontal deflection coil. In order to prevent or substantially reduce interference signals in the focusing coil (16) from the vertical and horizontal deflection coils, which interference is visible in a signal from a camera tube, the focusing coil comprises multifilar windings (35 and 36) having the same winding direction and sense. The windings ( ' 35 and 36) are connected in series such that the magnetic fields produced by each winding are of the same polarity.
