  • Patent number: 9275846
    Abstract: A light source device comprising a filament showing high electric power-to-visible light conversion efficiency is provided. A light source device comprising a translucent gastight container, a filament disposed in the translucent gastight container, and a lead wire for supplying an electric current to the filament is provided. The filament comprises a substrate formed from a metal material and a visible light reflectance-reducing film coating the substrate for reducing visible light reflectance of the substrate. The reflectance of the substrate for visible lights is thereby made low, and the reflectance of the substrate for infrared lights is thereby made high. Therefore, radiation of infrared lights is suppressed, and visible luminous efficiency can be enhanced.

  • Publication number: 20160039143
    Abstract: An imprint method for transferring a pattern formed on a mold onto a resin on a substrate. The substrate is held on a holding surface. A resin on the substrate is brought in contact with the mold. A partial region of the substrate is thermally deformed in a deforming step by irradiating the partial region with light. The resin is cured. The resin in contact with the mold is released. In at least a portion of the period during the deforming step, a region different from the partial region is held at a predetermined suction force, while holding the partial region at a suction force lower than the predetermined suction force.

  • Patent number: 9201298
    Abstract: An imprint method of transferring a pattern formed on a mold onto a resin on a substrate. The substrate is held on a holding surface by suction. A shape of a substrate-side pattern area pre-existing on the substrate is deformed. A resin on the pattern area is brought in contact with the mold. Positions of the pattern of the mold and of the pattern area are adjusted. The resin is cured and the mold is released from the resin in contact with the mold. A deformation force, which is greater than a maximum static frictional force acting between a rear surface of the substrate corresponding to the pattern area and the holding surface, is applied to the substrate. A suction force acting on the rear surface of the substrate corresponding to the pattern area in deforming is less than a suction force acting on the substrate in adjusting.
