  • Patent number: 10338749
    Abstract: An optical device includes a light-guiding plate that guides light in a plane parallel to an emission surface that emits light, and a sensor for detecting an object located on an emission surface side using light that passes through a back surface opposite to the emission surface and through the emission surface. The light-guiding plate has light convergence portions that receive light guided by the light-guiding plate and each have optical surfaces that cause light to be emitted from the emission surface in directions in which the light substantially converges at or scatters from one convergence point or one convergence line in a space, and the convergence points or the convergence lines for the light convergence portions are different from each other, and an image is formed in the space on the emission surface side by a collection of the convergence points or the convergence lines.

  • Patent number: 9481049
    Abstract: A method of cutting a cut member out of an original sheet by means of thermal cutting and machining, and includes a hole-cutting process, a finishing process, and an outer periphery-cutting process. During the hole-cutting process, a hole is created in the original sheet by means of thermal cutting while leaving a machining allowance in addition to the finished size of the hole. During the finishing process, a cutting tool is inserted into the hole which has been created through the hole-cutting process, and the cutting tool is guided along the inner circumference of the hole so as to cut the thermally-cut end surface in order to machine the hole to the finished size. During the outer periphery-cutting process, the outer periphery of the cut member is cut by means of thermal cutting to take the cut member out of the original sheet.

  • Publication number: 20100032061
    Abstract: A method for manufacturing a Ni-based alloy article which elutes little Ni even when used in a high-temperature water environment for a long period comprises heating the Ni-based alloy in a carbon dioxide-containing atmosphere for a set period of time at an elevated temperature to form an oxide film comprising chromium oxide on a surface thereof. Using carbon dioxide as an oxidizing gas produces an oxide film of generally uniform thickness along a length of the article being treated so that resistance to nickel elution is more uniform over the entire article.
