  • Publication number: 20200395133
    Abstract: A nuclear fusion system includes: a muon generation unit for generating negative muons; a gas supply unit for circulating and supplying gaseous deuterium or gaseous deuterium-tritium mixture as raw material gas for a nuclear fusion reaction; and a Laval nozzle for accelerating the raw material gas to supersonic velocity including a flow regulation portion in which the muons are decelerated and a reaction portion in which the nuclear fusion reaction occurs, wherein an oblique shockwave, which is generated as a result of collision of a shock wave generator arranged inside the reaction portion and the raw material gas accelerated to supersonic velocity, converges on a center axis of the Laval nozzle, and thereby a high-density gas target is retained in a gas phase, and wherein the muons are introduced into the high-density gas target, and thereby the nuclear fusion reaction is caused to occur.

  • Publication number: 20200223885
    Abstract: The present application addresses the problem of providing an Fc-binding protein having an improved antibody separation ability. The present application also addresses the problem of providing a high-accuracy antibody separation method using an insoluble carrier having the protein immobilized thereon. The problems can be solved by: an Fc-binding protein in which at least an amino acid substitution at a specific position therein occurs and which has reduced affinity for an antibody; and an antibody separation method including allowing an equilibration buffer solution to pass through a column in which an insoluble carrier having the protein immobilized thereon is filled to equilibrate the column, adding a solution containing an antibody to cause the adsorption of the antibody onto the carrier, and eluting the antibody adsorbed on the carrier using an elution solution.

  • Patent number: 10502698
    Abstract: The type and/or properties of a substance included in an object is identified highly accurately regardless of the thickness of the substance. A data processing apparatus processes counts detected at each of pixels of a photo counting detector in each of a plurality of energy ranges of X-rays. The X-rays are radiated from an X-ray tube, and transmitted through an object. The apparatus calculates an image of the object based on the counts, and sets a region of interest on the image. The apparatus further removes, from the image, pixel information showing a background present in the region of interest, and calculates, pixel by pixel, inherent information inherent to the substance, based on the counts detected at each of the respective pixels in each of the energy ranges of the X-rays in the region of interest. The inherent information indicates a transmission characteristic inherent to the X-rays.

  • Patent number: 10308139
    Abstract: A vehicle management method is provided for managing an electric vehicle by using a management server based on vehicle-specific ID information that defines a condition of use transmitted from an onboard controller. The vehicle management method includes acquiring vehicle ID information from the electric vehicle by using the management server; determining the vehicle ID information to be valid if the vehicle ID information acquired falls within a use period set in advance and determining the vehicle ID information to be invalid if the vehicle ID information acquired falls outside a use period set in advance; and applying a prescribed limitation to charging of a battery of the electric vehicle having the vehicle ID information upon determining that the vehicle ID information is invalid.
