  • Patent number: 11933743
    Abstract: An imaging control apparatus obtains a plurality of images at different radiation energies, the images having been obtained as a result of irradiating a subject with radiation whose energy changes during one shot, and detecting, a plurality of times, the radiation that has passed through the subject during the one shot; generates an energy subtraction image by performing energy subtraction processing using a plurality of images; and generates a difference image using a plurality of generated energy subtraction images.

  • Patent number: 10653564
    Abstract: The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.

  • Publication number: 20190201247
    Abstract: A device for manufacturing an absorbent body includes: a shaping unit that includes a recessed portion and that makes liquid absorbent fiber and superabsorbent polymer to be deposited in the recessed portion, shaping the absorbent body; and a supply unit that supplies the liquid absorbent fiber and the superabsorbent polymer to the recessed portion. The recessed portion includes a protruding portion, and the protruding portion protrudes from a bottom surface and includes an inclined surface. In a cross section orthogonal to a ridge line of the protruding portion, an angle of the inclined surface with respect to a surface parallel to the bottom surface is greater than an angle of repose of the superabsorbent polymer and smaller than 90 degrees.

  • Patent number: 9089457
    Abstract: A bodily fluid absorbent article adapted to absorb bodily fluid over a wide range thereof. An absorbent structure in the bodily fluid absorbent article includes an upper absorbent component and a lower absorbent component. The absorbent structure further includes one of a dispersing surface constituting the upper absorbent component and kept in contact with the lower absorbent component and a dispersing surface constituting the lower absorbent component and kept in contact with the upper absorbent component. Such dispersing surface exhibits a dispersion velocity for bodily fluid higher than those exhibited by the absorbent sections defined immediately above and under this dispersing surface.

  • Publication number: 20130243951
    Abstract: A device that applies adhesive on one side of a continuous sheet that travels, by acting air discharged from an air discharge hole of a head on the adhesive discharged from an adhesive discharge hole of the head. The device includes a first air curtain forming member positioned at a location on a downstream side of the head in a direction of travel of the continuous sheet, to oppose the head with a space therebetween, and forms a first air curtain by emitting air toward the one side of the continuous sheet. The device includes a pair of second air curtain forming members positioned at locations at outer sides from head in a width direction of the continuous sheet, to respectively oppose the head with spaces therebetween, and forms second air curtains by emitting air toward the one side of the continuous sheet.

  • Publication number: 20100198179
    Abstract: Occurrence of a protuberance due to swelling of superabsorbent resin is prevented in an absorbent article. An absorbent article includes: a fluid-permeable surface sheet; a fluid-impermeable back face sheet; and a liquid-absorbent core that is between the surface sheet and the back face sheet and that includes hydrophilic fiber and superabsorbent resin, the liquid-absorbent core having a plurality of through holes formed thereon and high-density regions, the high-density regions being each provided at a position adjacent to each of the through holes, a density of the superabsorbent resin in each of the high-density regions being higher than in another region.
