  • Publication number: 20240166736
    Abstract: An objective of the present invention is to provide an anti-TSPAN8/anti-CD3 bispecific antibody and an anti-TSPAN8 antibody usable in treatment or prevention in human. A human monoclonal antibody producing mouse was immunized with a peritoneal disseminated cancer cell isolated from a patient, to obtain an antibody 16B11 and an antibody 16B12 that selectively bind to a peritoneal disseminated cancer cell. These antibodies were anti-TSPAN8 antibodies that bind to the region from amino acid positions 126 to 155 of TSPAN8 and exhibited strong binding activity to TSPAN8 expressed in the peritoneal disseminated cancer cell. Further, an anti-TSPAN8(16B11)-anti-CD3 bispecific antibody produced based on the sequence of 16B11 exhibited a cytotoxic activity against the TSPAN8-expressing cancer cell in vitro, exerted an anti-tumor action on TSPAN8-expressing cancer cell-bearing mice in vivo, and extended the lifetime of peritoneal dissemination model mice.

  • Patent number: 10328468
    Abstract: A method of managing reuse of a returnable bottle is disclosed. The method individually manages returnable bottles so as to manage reuse linked with their individual states of use and thereby enable reusable bottles to be separated from other bottles in a scientific manner. The method comprises, at the time of new production of a returnable bottle body, forming on a bottle body surface a product identification mark part engraved with an identification code as product identification data of the bottle body, reading the product identification mark part and writing and storing the product identification data of the bottle body in the storage medium linked with individual transport state data relating to transport of the bottle body, and judging permission for continued reuse of the bottle body based on the individual transport state data stored in the storage medium.

  • Patent number: 9025422
    Abstract: The present invention relates to a plasmon generator, in which a surface plasmon is excited by application of light. The plasmon generator extends along one direction. The plasmon generator includes a first end surface that is positioned on one end in the one direction and at which near-field light is generated along with the excitation of the plasmon; and a second cross section that is substantially parallel to the first end surface and is away from the first end surface. The first end surface has a polygonal shape that does not have a substantially acute inner angle. The second cross section has an upper part that has a shape substantially the same as or similar to that of the first end surface and a flare shaped lower part that is connected to the upper part and has a width that increases as it is far from the upper part.

  • Patent number: 8462594
    Abstract: A thermally-assisted magnetic recording head includes a medium facing surface, a magnetic pole, a waveguide including a core and a cladding, and a plasmon generator. The magnetic pole is located forward of the core in the direction of travel of a magnetic recording medium. The plasmon generator is disposed between the core and the magnetic pole. The core has an evanescent light generating surface facing toward the plasmon generator. The plasmon generator has a front end face located in the medium facing surface, a flat surface facing toward the'evanescent light generating surface, and first and second side surfaces that are at a distance from each other and are located farther from the evanescent light generating surface than is the flat surface.

  • Patent number: 8325570
    Abstract: A thermally-assisted magnetic recording head includes: a medium facing surface; a magnetic pole; a waveguide including a core and a cladding; a plasmon generator; and a protruding member. The protruding member is disposed between the medium facing surface and a front end face of the core facing toward the medium facing surface. The protruding member has a first end face located in the medium facing surface, and a second end face facing toward the front end face of the core and receiving light having propagated through the core and passed through the front end face. The protruding member is formed of a metal different from both a material forming the magnetic pole and a material forming the plasmon generator. The protruding member is heated and expanded by the light received at the second end face, so that the first end face gets protruded toward a magnetic recording medium.
