  • Patent number: 8591233
    Abstract: A magnetic device includes a cylindrical portion and a flange portion. The cylindrical portion is mounted with a cylindrical shaped flexible sleeve. The sleeve is axially longer than the cylindrical portion and includes an outer peripheral concavo-convex portion. When one end of the sleeve is abutted on a flange portion, the other end of the sleeve is projected above an attractive surface to form a keeper housing recess. The sleeve is relatively moved in an axial direction of the magnetic device to be inserted into and removed from a top end of the cylindrical portion. The magnetic device is used under condition the sleeve is fitted, an outer side surface of the magnetic device including the outer peripheral concavo-convex portion of the sleeve and the flange portion abutted on the one end of the sleeve is embedded in a denture base, and the keeper housing recess is exposed.

  • Patent number: 7581342
    Abstract: A display device includes an ultraviolet light source, a color light source, and a filter selectively hit by their lights. The filter has a first area part for displaying the first display contents excluding an overlapped parts when the ultraviolet light is emitted, a second area part for the second display contents excluding the overlapped parts when the color light is emitted, and a third display part for displaying the overlapped parts when one of the ultraviolet and color light is emitted. The first area part blocks the color light and produces visible light when the ultraviolet light hits the first area part, the second area part allows the ultraviolet and color lights to pass therethrough, and the third area part allows the ultraviolet and color lights to pass therethrough and produces the visible light when the ultraviolet light hits the third area part.
