Abstract
Abstract A saturable reactor comprising an H-shaped core on which are wound two coils, each coil being divided respectively into two coil parts and each coil part being constituted of symmetrical winding on the left and right arms of a yoke with the coupling part formed on the middle of the aforementioned core as the center. One of the aforementioned coils is constituted so that the magnetic flux generating direction of the pair of coil parts wound on the yoke mentioned above would be identical, while the other coil mentioned above is constituted so that the magnetic flux generating direction of the pair of coil parts wound on the yoke mentioned above would be mutually opposite.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A raster distortion correcting reactor comprising an H-shaped core comprised of a pair of parallel, spaced yokes connected at their mid-sections by a coupling member, one of the yokes having wound thereon first and second coils, said coils each being divided into two coil parts and each coil part being constituted of a symmetrical winding on the yoke arms on opposite sides of said coupling member, the first coil being so constituted that, when electric current is caused to flow through it, magnetic fluxes generated in the two divided coil parts assume the same direction, while said second coil is so constituted that, when electric current is caused to flow through it, magnetic fluxes will be generated in opposite directions in the two divided coil parts.
Claim 2
Dependent Claim
126 words
A raster distortion correcting reactor comprising an H-shaped core comprised of a pair of parallel, spaced yokes connected at their mid-sections by a coupling member, one of the yokes having wound thereon first and second coils, said coils each being divided into two coil parts and each coil part being constituted of a symmetrical winding on the yoke arms on opposite sides of said coupling member, the first coil being so constituted that, when electric current is caused to flow through it, magnetic fluxes generated in the two divided coil parts assume the same direction, while said second coil is so constituted that, when electric current is caused to flow through it, magnetic fluxes will be generated in opposite directions in the two divided coil parts.
Claim 3
Dependent Claim
126 words
A raster distortion correcting reactor comprising an H-shaped core comprised of a pair of parallel, spaced yokes connected at their mid-sections by a coupling member, one of the yokes having wound thereon first and second coils, said coils each being divided into two coil parts and each coil part being constituted of a symmetrical winding on the yoke arms on opposite sides of said coupling member, the first coil being so constituted that, when electric current is caused to flow through it, magnetic fluxes generated in the two divided coil parts assume the same direction, while said second coil is so constituted that, when electric current is caused to flow through it, magnetic fluxes will be generated in opposite directions in the two divided coil parts.
Claim 4
Dependent Claim
126 words
A raster distortion correcting reactor comprising an H-shaped core comprised of a pair of parallel, spaced yokes connected at their mid-sections by a coupling member, one of the yokes having wound thereon first and second coils, said coils each being divided into two coil parts and each coil part being constituted of a symmetrical winding on the yoke arms on opposite sides of said coupling member, the first coil being so constituted that, when electric current is caused to flow through it, magnetic fluxes generated in the two divided coil parts assume the same direction, while said second coil is so constituted that, when electric current is caused to flow through it, magnetic fluxes will be generated in opposite directions in the two divided coil parts.
Claim 5
Dependent Claim
115 words
A raster distortion correcting reactor in accordance with claim 1, and further comprising a fixed magnet mounted on one end of the H-shaped core, a disc-shaped movable magnet rotatably mounted on the other end of said core, said fixed magnet being fixed with one of its magnetic poles closely facing one end of the yoke of said core on which said coils are wound, and said disc shaped movable magnet being magnetized in the direction of its diameter with the face of the disc being arranged in such a manner that it directly touches both the other end of said yoke on which said coils are wound and the adjacent end of the other yoke.
Claim 6
Dependent Claim
61 words
A raster distortion correcting reactor in accordance with Claim 1 and further comprising two disc-shaped movable magnets rotatably mounted on the ends of said H-shaped core, said movable magnets being magnetized in the direction of their diameter and the disc surfaces being so arranged as to rotate in close contact with the ends of the two yokes of the above-mentioned core.
Claim 7
Dependent Claim
101 words
A raster distortion correcting reactor in accordance with claim 1 and further comprising a first magnet fixedly mounted on one end of the H-shaped core and a second, disc-shaped movable magnet rotatably mounted on the other end of said core, said fixed magnet being fixed to one end of the coil-wound yoke of the core with its magnetic poles in close contact with the yoke end, said movable magnet having a central aperture and being magnetized in the direction of its diameter, and the other end of said coil wound yoke being telescoped into said central aperture of said movable magnet.
