  • Patent number: 8773877
    Abstract: A power supply circuit enabling provision of good energy efficiency and downsizing is provided. A power supply circuit 1 according to the present invention includes: input terminals 2, 2 connected to a commercial power supply 10; a winding 4 serially connected between the input terminals 2, 2 via input conductors 3; and a plurality of output terminals 6A, 6B connected to opposite ends of respective windings 4A and 4B resulting from dividing the entire winding 4 into a plurality of parts via output conductors, the respective output terminals 6A and 6B being independently connected to respective loads 20A and 20B.

  • Patent number: 5416674
    Abstract: An attractive displaying device whereby an ultraviolet radiation lamp, which is hidden from plain view, contains a transparent tube that coaxially receives the ultraviolet lamp and which is rotatable about an axial center line. Images are painted or printed on either the outer surface of the ultraviolet lamp, or on a substantially transparent film placed over the surface of the transparent tube, with a fluorescent ink which emits light when ultraviolet light is radiated upon it. The lighted images are projected onto a concave reflective surface, which may also have images painted on it with a fluorescent ink. The rotatable tube allows for movement of the images against the reflective surface; and a three dimensional effect can be achieved by making it look as if the projected images are passing behind the images that are painted on the reflective surface. The display unconventionally provides illuminated images against a dark background as opposed to a dark image against a light background.
