  • Patent number: 9833972
    Abstract: In a laminated steel plate in which steel plates are joined to both faces of a core layer, the core layer is formed of a meshed wire group formed using wires in a mesh form and a resin sheet, the wires forming the meshed wire group have a tensile strength of 601 MPa or higher, and an opening of the meshed wire group is equal to or less than ten times the thickness of the steel plates. By thus defining the tensile strength of the wires, light-weightness can be achieved compatibly with high rigidity and shock resistance, and by defining the opening of the meshed wire group, workability and shape stability after being processed can be improved.

  • Patent number: 9799256
    Abstract: An image processing device includes a light detection unit and an image conversion unit. The light detection unit is configured to detect a first grayscale value of a background image. The background image is an image seen by a user through an at least partially transparent display panel. The image conversion unit is configured to generate a correction image having a second grayscale value obtained by subtracting a third grayscale value pertaining to the first grayscale value from a fourth grayscale value of an input image inputted to the at least partially transparent display panel. The input image is an image intended to be displayed on the at least partially transparent display panel.

  • Patent number: 9478046
    Abstract: An image processing device includes a hue changer and a color gamut converter. The hue changer changes a hue of input image data from a first hue to a second hue by combining a phase with a hue of a primary color when the input image data is at or adjacent the primary color, the phase being based on a hue angle phase difference between a first color gamut and a second color gamut narrower than the first color gamut. The color gamut converter preserves a hue about image data from the hue changer and converts a color gamut from the first color gamut to the second color gamut.

  • Publication number: 20160010713
    Abstract: The invention provides an impact absorbing component capable of stable bellows-shaped crushing deformation irrespective of the direction an impact load is exerted in, with a short bucking wavelength and large buckling load. A laminated metal sheet (impact absorbing component) includes a member that is formed by working the laminated metal sheet, in which surface layers made from metal sheets having a higher Young's modulus and density than those of a core layer are laminated onto both faces of the core layer, into a profile including at least two ridge lines, and that configures 50% or more of the maximum peripheral length of component cross-sections, wherein a sheet thickness ratio (tc/tf) of the sheet thickness (tc) of the core layer to the sheet thickness (tf) of the surface layers is 10.0 or less.

  • Publication number: 20150237320
    Abstract: An image processing apparatus includes a signal input converter, a color gamut converter, a blend coefficient setter, and a color synthesizer. The signal input converter converts input signals having a first color gamut representing image data to first image signals that are at least substantially linear. The color gamut converter converts the first image signals to second image signals having a second color gamut narrower than the first color gamut. The blend coefficient setter sets a blend coefficient corresponding to a synthesis ratio of the first and second image signals based on saturation obtained from the input signals. The color synthesizer generates synthesized image signals obtained by synthesizing the first and second image signals at a ratio according to the set blend coefficient.
