Definitions

  • the cyclically varying horizontal scanning must be varied at a lower vertical rate, since the magnitude of a horizontal scanning current is parabolical.
  • nominal correction can be produced by this means.
  • saturable reactor device and circuit connections for correcting pincushion distortion such as those described in U.S. Pats, No. 2,906,919, No. 3,346,765, and No. 3,444,422.
  • the present invention provides a saturable reactor which is extremely easily assembled to be compact and manufactured to have uniform quality.
  • the present invention provides a saturable reactor comprised of a pair of bar type cores provided with primary coils and secondary coils and arranged in parallel and a pair of magnets which have opposed magnetic poles with different polarity to supply a biased magnetic flux to the cores and are mounted so that the magnetic poles contact the ends of said cores at the same time, wherein a pair of said primary coils which are wound on a pair of cores generate both magnetic fluxes in the same direction in reference to the direction of the biased magnetic flux and a pair of secondary coils which are wound on a pair of cores generate the magnetic fluxes in opposite directions to each other in reference to the direction of said biased magnetic flux.
  • FIG, 1 is a cross sectional front view of important parts of a saturable reactor according to the present invention
  • FIG. 3 is a cross sectional front view of important parts of said saturable reactor showing another embodiment
  • FIGS. 1 and 2 there is shown a saturable reactor comprised of a pair of bar type cores 1 and l which are arranged in parallel, a pair of primary coils 2 and 2' which are wound on said cores respectively, a pair of secondary coils 3 and 3 which are wound on said cores respectively and a pair of magnets 4 and 4' which have opposed magnetic poles with different polarities to supply the biased magnetic flux f to the cores and are provided at both ends of a pair of cores.
  • Said reactor is housed in a suitable supporting member, for example, case 5.
  • the primary coils are wound such that when the flux of the first primary coil is in the same direction as the biased magnetic flux of its core, the flux of the second primary coil is in the same direction as the biased magnetic flux of its core and, conversely, when the flux of the first primary coil is in the opposite direction as the biased magnetic flux of its core, the flux of the second primary coil is also in the opposite direction as the biased magnetic flux of its core.
  • a pair of said secondary coils 3 and 3 are wound so as to generate the magnetic fluxes in the opposite direction to each other in reference to the direction of the biased magnetic flux.
  • the direction of the generated magnetic fluxes is reversed in accordance with the direction of the deflection current as known from the prior art.
  • the power supplies to which the primary coils and secondary coils are to be connected and the method of connection can be determined according to the purpose as known technically.
  • magnets 4 and 4' can be energized in the direction of thickness as shown in FIGS. 3 and 4 and at least one of the magnets can be disc type magnet 4, having a flux varying at a given radius from one radial to another, which is rotatable at support shaft 41 provided at the center of the magnet.
  • the magnetizing bias of the cores can be adjusted because the amount of the biased magnetic flux can be changed as disc-type magnet 4 is rotated. If the magnet is made to be of the rotary type, it is desirable to fonn a knurled surface 42 on the magnet as shown in FIG. 4, thus smoothing rotation of the magnet.
  • the magnetizing bias of the core can be changed by rotating the disctype magnet which is energized in the radial direction. If one or all magnets are made to be movable magnet 4, the magnets can be moved in the radial direction by attracting the magnets to the ends of a pair of cores as shown in FIG. 5. In this case, it is desirable to use the magnet energized in the radial direction.
  • the winding direction of said primary and secondary coils in the embodiment of FIG. 1 is different from that in the embodiment in FIG. 3.
  • the winding direction of these coils is detemrined according to the direction of biased magnetic flux f.
  • secondary coils wound on each of said cores which are arranged to generate magnetic fluxes in opposite directions to each other with reference to the direction of said biased magnetic flux.
  • a saturable reactor according to claim I wherein at least one of said magnets is arranged so as to be shifted in its radial direction.
  • a saturable reactor according to claim I wherein said primary coils are wound directly on said cores and said secondary coils are wound on said primary coils.
