  • Publication number: 20190128369
    Abstract: In a torsional vibration reducing device, a protrusion projecting radially outward of the rotating body is firmed on an inner wall surface. The protrusion is formed on a rotation direction side of a rotating body relative to a straight line passing through a rotation center of the rotating body and a center of a rolling element when the rolling element is located in a middle between both end positions to which the rolling element swings within the roller chamber, and while the rolling element is located at an end portion of a roller chamber on the rotation direction side of the rotating body, a gap is equal to or less than a predetermined value between the rolling element and a wall surface of the roller chamber on a straight line passing through a rotation center of the rotating body and a tip of the protrusion.

  • Patent number: 10011133
    Abstract: A liquid discharge device includes a liquid discharge head that includes a nozzle from which liquid is discharged and a liquid channel communicating with the nozzle, and that discharges liquid from the nozzle. The nozzle has an inner wall surface having an uneven pattern including a recess where the inner diameter of the nozzle is increased and a projection where the inner diameter of the nozzle is smaller than that in the recess. In a case where ink is continuously discharged from an identical nozzle, at a time when a meniscus in the nozzle after previous discharge is located closer to an initial position before discharge than a center position between the initial position and a position at which the meniscus is most greatly drawn toward the liquid channel, subsequent discharge is performed.

  • Publication number: 20170275376
    Abstract: The present inventors attempted to produce antibodies that neutralize the activity of a substance having an activity of functionally substituting for FVIII to be used for the method of measuring the reactivity of FVIII in the presence of a substance having an activity of functionally substituting for FVIII. As a result, the inventors discovered that by using the produced antibodies, FVIII activity in the plasma of a hemophilia A patient can be evaluated accurately by one-stage clotting assay based on APTT, and also that FVIII inhibitor titer in the plasma of a hemophilia A patient carrying a FVIII inhibitor can be evaluated accurately by Bethesda assay based on APTT.

    Abstract: Various bispecific antibodies that specifically bind to both blood coagulation factor IX/activated blood coagulation factor IX and blood coagulation factor X and functionally substitute for the cofactor function of blood coagulation factor VIII, that is, the function to promote activation of blood coagulation factor X by activated blood coagulation factor IX, were produced. From these antibodies, multispecific antigen-binding molecules having a high activity of functionally substituting for blood coagulation factor VIII were successfully discovered.
