摘要： A deflection yoke in which variation in the magnetizing amount due to individual difference of permanent magnets is corrected and correction of appropriate raster distortion can be sustained even for the temperature variation of an apparatus, and a cathode ray tube unit comprising it. The correction unit (340) in the deflection yoke (30) of a CRT unit (1) is fixed, onto at least one of the opposite end faces (341a, 341b) of a permanent magnet (341), with a magnetic body (342) having such characteristics that the permeability varies with negative temperature characteristics so as to cover it. The deflection yoke (30) is provided with a pair of vertical correction units (340) symmetrically to the tube axis of a CRT (10).

摘要： The present invention relates to a yoke ring for use in a deflection unit in a cathode ray tube (CRT), said yoke ring having a neck and a flared side, and being defined by an inner and an outer contour. According to the invention, the inner contour is periodically deformed in the radial direction, the contour having at least two local minima and maxima. This deformation influences the magnetic field generated by the coils in the CRT, leading to improved FOS performance. In particular, astigmatism, coma and raster errors are reduced.

摘要： A monochrome cathode ray tube (CRT) yoke includes harmonic windings for correcting spot distortion. In a first embodiment of the invention, the yoke (8) includes harmonic windings in the entrance region of the yoke and harmonic windings in the exit region of the yoke. The harmonic windings (14) in the entrance region produce a barrel-shaped field for correcting spot astigmatism along the diagonals of the CRT. The harmonic windings (16) in the exit region of the yoke produce a pincushion-shaped field for correcting spot elongation along the diagonals of the CRT. In a second embodiment of the invention, the yoke includes harmonic windings only in the entrance region. A stigmator (6) includes quadrupole coils driven at low power vertical scan rates. This allows the stigmator to be positioned near the electron gun and reduces the length of the CRT. In a third embodiment of the invention, the yoke includes harmonic windings only in the exit region.

摘要： The scanning velocities of a plurality of electron beams having beam intervals can be independently modulated. A current is supplied to a velocity modulation coil to modulate the scanning velocities of a plurality of electron beams 19A, 19B emitted from electron guns housed in the neck portion of a CRT and sharpen the profile of an image. The velocity modulation coil consists of three upper-side coils 27A, 27B, 27C and three lower-side coils 28A, 28B, 28C, and has a coil shape that generates an asymmetric quadripolar magnetic field, and independent magnetic fields obtained from these two velocity modulation coils respectively modulate the scanning velocities of a plurality of electron beams 19A, 19B almost independently of one another.

摘要： In a cathode ray tube (10), an electron beam is directed towards a faceplate (20) having an electrode (22) biased at screen potential and is magnetically scanned across the faceplate (20) to impinge upon phosphors (23) thereon to produce light depicting an image. A six-pole coil (15) is disposed proximate the deflection yoke (16) and/or on the tube neck (14) to modify the focus of the red, green and blue electron beams to control focus. An electrode (46) between the tube neck (14) and the faceplate (20) is biased at or above screen potential to deflect electrons over a greater total angle than is obtained from the magnetic deflection.

摘要： The invention relates to a deflection ring of sintered MgZn-ferrite material. In accordance with the invention, this deflection ring is characterized in that the majority of the grains of the sintered material have a monodomain structure.

摘要： A deflection apparatus comprising a cathode ray tube produces a field gradient that reduces a tendency of a major axis of a beam spot to become elongated at each corner, at each end of a horizontal axis and at each end of a vertical axis of a display screen (22) relative to the beam spot at the center of the display screen. A beam spot stigmator (24) causes the beam spot to be substantially anastigmatic at each of the corners, the end of the horizontal axis and the end of the vertical axis of the display screen. In an embodiment of the invention, means (11) are provided for producing a first non-uniform field providing a lensing action containing a time varying field portion not produced by the deflection coils (10, 99), said means (11) comprising a quadrupole doublet.
