  • Publication number: 20150028977
    Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core.

  • Patent number: 5373416
    Abstract: A ballast holder which can be fabricated from a single piece of bent sheet metal material, includes a gusseted riser structure, a base portion extending rearwardly from the foot of the riser structure, and a top flange portion extending in a forwardly direction from the top end of the riser structure for securing one of the mounting flanges of a ballast. The height of the rigid riser structure is chosen to be at least as great as the maximum height of a standard ballast to be held thereby. The ballast holder is used to install a ballast in an inverted position within a lighting fixture housing and can accommodate different sized ballasts. The ballast holder also reduces the amount of structure between the ballast and the overlying reflector element of the lighting fixture and thereby reduces the tendency of the ballast holding structure to bow or distort the lighting fixture's reflector where space is limited.
