  • Patent number: 10373324
    Abstract: A measurement apparatus that is capable of positively generating a projection pattern suitable for a to-be-read object. A camera scanner as the measurement apparatus projects a projection pattern formed by a plurality of projection lines on a to-be-read object to thereby measure the bending of the to-be-read object. A distance to the to-be-read object is measured, and distance distribution information of the to-be-read object for identifying a shape, a size, and a position of the to-be-read object is generated based on the measured distance. The projection pattern is generated based on the generated distance distribution information of the to-be-read object.

  • Patent number: 10074476
    Abstract: A ferrite composition composed of a main component including 26 to 46 mol % of an iron oxide in terms of Fe2O3, 4 to 14 mol % of a copper oxide in terms of CuO, 0 to 26 mol % of a zinc oxide in terms of ZnO, and a residue of 40.0 mol % or more of a nickel oxide in terms of NiO. The ferrite composition, with respect to 100 parts by weight of the main component, is also composed of a subcomponent including 0.8 to 10.0 parts by weight of a silicon compound in terms of SiO2, 1.0 to 15.0 parts by weight of a cobalt compound in terms of Co3O4, and 0.7 to 30.0 parts by weight of a bismuth compound in terms of Bi2O3. A value of the cobalt compound content in terms of Co3O4 divided by the silicon compound content in terms of SiO2 is 0.4 to 5.5.

  • Patent number: 9984799
    Abstract: A ferrite composition comprises a main component and a sub component. The main component is comprised of 25.0 to 49.8 mol % iron oxide in terms of Fe2O3, 5.0 to 14.0 mol % copper oxide in terms of CuO, 0 to 40.0 mol % zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The sub component includes 0.2 to 5.0 wt % silicon oxide in terms of SiO2, 0.10 to 3.00 wt % bismuth oxide in terms of Bi2O3, and 0.10 to 3.00 wt % cobalt oxide in terms of Co3O4, with respect to the main component.

  • Patent number: 9979858
    Abstract: To specify a contour to be detected even when there are a plurality of candidates of the contour on the periphery of a photographing target, an image processing apparatus comprises: a determining unit which detects a plurality of candidate points being the candidates of the contour of a subject based on distance image information of the subject in an image, and determines an inspection-target area in the image based on the detected candidate points; and a specifying unit which detects line segments existing in the inspection-target area determined by the determining unit, based on luminance information of the inspection-target area, and specifies the line segment being the contour of the subject based on the candidate point from the detected line segments.

  • Patent number: 6736990
    Abstract: There can be provided an NiCuZn-based ferrite material containing an iron oxide, a copper oxide, zinc oxide and a nickel oxide in predetermined amounts as main components and a bismuth oxide, a silicon oxide, magnesium oxide and a cobalt oxide in predetermined amounts as additional components. Due to the predetermined amounts of the additional components, the ferrite material has an extremely good temperature characteristic (a change in permeability along with a change in temperature is small), a high quality coefficient Q and high strength.
