  • Patent number: 11904379
    Abstract: An object of the present invention is to propose a device capable of automatically insetting a tube into a bending die instead of doing so manually, even if the shape of a product exceeds two meters in length, the device comprising a bending die having a tube insetting portion, and a traveling body that includes a guide mechanism guiding a tube to an upper portion of the tube insetting portion, an auxiliary guide mechanism keeping the tube in the upper portion of the tube insetting portion, a insetting roll insetting the tube in the tube insetting portion, a pair of drive wheels rolling along lower rails, and a drive mechanism, wherein the traveling body moves and insets a tube into the bending die while having the auxiliary guide mechanism and the drive wheels grip the bending die.

  • Publication number: 20230294169
    Abstract: An object of the present invention is to propose a bending die capable of creating a product without causing buckling, even if the shape of the product is long or bent freely in three-dimensional space. The bending die according to the present invention is a bending die having a smooth shape formed by virtually and continuously moving, in three-dimensional space, a profile including a substantially circular-shaped first closed curve having a recess portion, wherein an opening width b of the recess portion is shorter than a groove width a of the recess portion, a tube insetting portion is formed by the recess portion, and the smooth shape is realized and created in real space using a three-dimensional printing technique.

  • Patent number: 10953476
    Abstract: A chuck device that allows easy attachment of a clamping target component and can provide powerful and highly reliable clamping includes a main body including a metal core part and an annular space coaxial with and formed around the metal core part; a rubber elastic body fitted in the annular space of the main body such that there is a pressure chamber between a circumferential wall that defines the annular space and the rubber elastic body, and a clearance for allowing a tubular clamping target component to be inserted between the rubber elastic body and the metal core part; and a passage for introducing a fluid to the pressure chamber, wherein the rubber elastic body is deformed to expand toward the metal core part by a pressure of a fluid introduced to the pressure chamber via the passage so that a tubular clamping target component that is attached to the metal core part is clamped by the metal core part and the rubber elastic body that has deformed to expand.

  • Patent number: 10821656
    Abstract: A pipe end processing device includes a female die and a male die. The female die has a through hole with one side thereof being radially increased, the through hole having the molding surface for forming the protrusion formed on an inner circumference on the one side of the through hole. The male die includes a metal core passed through the through hole of the female die and configured to be axially moved, and a tubular elastic body fitted on one end part of the metal core and protruding from the one side of the female die. The tubular elastic body is configured to be axially compressed by a movement of the metal core to radially expand by deformation thereby to press the surface to be processed of the pipe against the molding surface of the female die.

  • Publication number: 20090286963
    Abstract: The present invention relates to an antigenic fusionprotein, which carries multiple Gal?1,3Gal epitopes. The fusion protein according to the invention may also be comprised of a heavily glycosylated mucin part, which mediates binding to selectins, such as PSGL-1, and a part, which exhibits immunoglobulin properties, such as the Fc part of IgG. The fusionprotein according to the invention is preferably used as an absorber to prevent a hyperacute rejection of a xenotransplant, such as a pig tissue or organ transplanted into a human patient. In addition, the invention relates to a method for the prevention of a hyperacute rejection reaction in a patient who is to receive a xenotransplant.
