  • Patent number: 10558179
    Abstract: A shaft torque control device executes highly responsive shaft-torque control even when spring rigidity of a connection shaft connecting an engine and dynamometer varies, and has a feedback control system including a nominal plant imitating input-output characteristics of a test system, generalized plant having nominal plant; controller providing an input with use of outputs and variation term causing variation in the nominal plant on the basis of a variation transfer function. In the controller, setting is made to satisfy a design condition. Nominal plant is structured with a two-inertia system configured by connecting two inertia bodies via a shaft having spring rigidity equal to a predetermined nominal value set to be a lower limit value in an assumed variation range of spring rigidity of the connection shaft. The variation transfer function is a positive real function. Spring rigidity in the nominal plant Na increases from the nominal value.

    Abstract: The present invention provides an anti-Myl9 antibody or a Myl9 binding fragment thereof that binds to Myl9 and may inhibit the interaction between Myl9 and CD69 in humans, as well as a pharmaceutical composition comprising the same. A mouse anti-human/mouse Myl9 monoclonal antibody having binding affinity against Myl9 was obtained, and the sequence for the complementarity determining region (CDR) of said mouse anti-human/mouse Myl9 monoclonal antibody was identified. Accordingly, a humanized antibody comprising the CDR sequence of said mouse anti-human/mouse Myl9 monoclonal antibody in the variable region of heavy and light chains was produced.
