  • Patent number: 9233561
    Abstract: A lens sheet is provided with a lens layer which is formed by arranging lenses, which extend in a y direction as a first direction, in a plurality of lines in an x direction as a second direction which is a direction which is orthogonal to the first direction, and an ink absorbing layer which configures a surface on the opposite side with regard to a surface which is configured by the lens layer, where the thickness of an edge which is an end surface on one side of the lens layer in the x direction is thinner than the thickness of an edge which is an end surface on the other side. The printer performs recording from the edge which is a reference side toward the edge on the opposite side.

  • Publication number: 20150035889
    Abstract: A printer includes a liquid ejection section and a drive control section. The liquid ejection section is configured to eject a plurality of types of liquids and form dots having different sizes. The drive control section is configured to control a dot size of the liquids to be ejected by the liquid ejection section based on image data. When an image including a three-dimensional image in which a plurality of linear images are arrayed is printed on a medium, the liquid ejection section is configured to eject the liquids, at least in an end section area in an array direction of the linear images in a print area of the image, under a setting in which an ejection ratio of relatively small dots is set lower than in an inner area that is positioned more inward than the end section area.

  • Patent number: 7513959
    Abstract: When a non-oriented electrical steel sheet is manufactured, simultaneously having superior magnetic properties and high strengths, a composition containing 0.02% or less of C, 4.5% or less of Si, 5.0% or less (including 0) of Ni, and 0.2% to 4.0% of Cu is used, and a solute Cu is allowed to appropriately remain in finish annealing. In the steel sheet thus obtained, finely shaped Cu is precipitated by aging treatment, and while the magnetic properties are not degraded, the yield stress is increased to not less than CYS (MPa) represented by the following formula: note CYS=180+5,600[% C]+95[% Si]+50[% Mn]+37[% Al]+435[% P]+25[% Ni]+22d?1/2 where d is an average grain diameter (mm) of crystal grains.
