  • Patent number: 10729398
    Abstract: An X-ray phase contrast imaging device of the present invention can change an arrangement pitch of slits related to a multi-slit and an arrangement pitch of phase shift sections related to a phase grating. A positional relationship among the multi-slit 3b, the phase grating, and an FPD is determined based on the arrangement pitch of the slits related to the multi-slit, the arrangement pitch of the phase shift sections related to the phase grating, and an arrangement pitch of detection elements related to the FPD. Among these arrangement pitches, by changing the arrangement pitch of the slits and the arrangement pitch of the phase shift sections, the present invention can change the positional relationship among the multi-slit, the phase grating, and the FPD.

  • Publication number: 20190175126
    Abstract: Provided is a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject. According to the present invention, it is possible to provide a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject immediately before. That is, the apparatus of the present invention is provided with a phase grating 5 provided with a subject area and a reference area. Both areas each have a predetermined pattern that absorbs radiation, but the patterns are different from each other. In this area, an image of the phase grating 5 is observed in a moire pattern of a long period.

  • Publication number: 20170342657
    Abstract: Provided is a fabric having a novel design in which an uneven-surface design is partially formed by embossing. A polyurethane resin is applied to the surface of the fabric having, on the surface, a low fineness portion and a high fineness portion having a higher single fiber fineness than that of the low fineness portion, the fabric is dried; and embossing is performed on the surface of the fabric. By performing the embossing, while an uneven-surface design is not imparted to the high fineness portion by the embossing and a non-uneven-surface design portion 3 is formed, the uneven-surface design is imparted to the low fineness portion by the embossing and an uneven-surface design portion 2 is formed.

  • Publication number: 20160254116
    Abstract: A metal including a passivation film 33a with a thickness of 10 nm or more is used as a metal electrode (a focus cup electrode 33) for generating an electric filed in a vacuum. The focus cup electrode 33 is made of stainless steel. The stainless steel is immersed in a treatment solution to perform coating (passivation treatment) . Accordingly, the passivation film 33a can be formed to be thicker than 10 nm. In this manner, the passivation film 33a is thicker than 10 nm. Therefore, the surface is uniform, and the adhesion is excellent, and the number of pinholes is small. Accordingly, the withstand voltage performance can be improved.
