  • Patent number: 10052726
    Abstract: There is provided a method for creating machining data for a hybrid ultraprecision machining device for manufacturing a micro-machined product from a workpiece, the machining device comprising: an electromagnetic-wave-machining means for roughly machining the workpiece; a precision-machining means for precisely machining the roughly machined workpiece; and a shape-measurement means, wherein the creation of the machining data makes use of: information on original shape corresponding to shape of the workpiece; information on roughly-machining shape to be removed from the workpiece by the electromagnetic-wave-machining means; and stereoscopic model of after-electromagnetic-wave-machining shape which is obtained by subtracting the roughly-machining shape from the original shape, wherein the machining data is created for electromagnetic-wave machining on the basis of information on a plurality of sliced portions obtained by partially slice-cutting from the stereoscopic model of the after-electromagnetic-wave-machi

  • Patent number: 8922912
    Abstract: A Fresnel lens comprises a first surface, and a second surface being the reverse side surface of the first surface and having a plurality of lens surfaces. Each lens surface is configured from a part of a side surface of an elliptical cone, which has an apex located on the second surface side and a bottom surface located on the first surface side. Here, in the Fresnel lens, any normal line intersecting with the lens surface configured from the part of the side surface of the elliptical cone among normal lines of respective points on the first surface is non-parallel to a central axis of the elliptical cone corresponding to the lens surface with which the any normal line intersects.

  • Patent number: 8742435
    Abstract: The LED lighting device in this invention comprises a light source, a first face sheet, and a reflection sheet. The light source comprises a plurality of LED chips which are configured to emit lights having wavelengths which are different from each other. The first face sheet has a rear surface. The rear surface is defined as a diffusing and reflecting surface which is being configured to diffuse and reflect the lights which are emitted from the LED chips. The first face sheet is provided with a plurality of apertures. The reflection sheet has a second reflecting surface. The second reflecting surface is configured to reflect the light which is reflected from the diffusing and reflecting surface of the first face sheet toward the first face sheet. Each the aperture is shaped to pass the light which is reflected from the second reflecting surface.

  • Patent number: 5463266
    Abstract: A long thin rectangular body of piezoelectric material is divided, in the longitudinal direction thereof, into a plurality of regions which include at least one driving region and at least one driven region. The driven region includes two electrodes which are formed such as to respectively cover opposite side surfaces of the driven region in a plane parallel to the longitudinal direction and to respectively extend inwardly in a transverse direction of the body by a predetermined amount over two major surfaces of the driven region. The driven region is polarized in a lateral direction of the body. As an alternative, the driven region is provided with two electrodes each of which consists of a pair of relatively narrow strip-like portions. The strip-like portions of one electrode extend over the two major surfaces adjacent to one edge of the driven region in the longitudinal direction of the body. The strip-like portions of the other electrode are similarly provided at the opposite side of the driven region.
