Inventor: TAKAHASHI YUKI
IPC: C12P21/08
Filed: 2009-09-03
Abstract: Disclosed are: an anti-human immunoglobulin M monoclonal antibody which can react with human immunoglobulin M specifically to form an immunological aggregate through the antigen-antibody reaction with the human immunoglobulin M in a solution; an immunoassay using the monoclonal antibody; an inhibitor which can inhibit a non-specific reaction induced by human immunoglobulin M which cannot be inhibited by the conventional techniques; and an immunoassay in which a non-specific reaction induced by human immunoglobulin M is inhibited. In the selection of a monoclonal antibody capable of reacting with human immunoglobulin M by employing the reactivity in a solution as a measure for the evaluation, it becomes possible to produce a novel monoclonal antibody which can cause the aggregation of human immunoglobulin M by itself and enables a practical immunoagglutination measurement.

Title: Vehicle
Inventor: OHBAYASHI MOTONARI
IPC: B60W40/10
Filed: 2009-05-27
Abstract: Provided is a vehicle capable of improving the precision of a stop decision of wheels.  Either a stop-deciding time period that is the product of the pulse width of the wheel speed pulses just before the no-output time period, for which no wheel speed pulse is outputted from a wheel speed sensor (3), and (2 1/2  + 1), or a correction time period, which is corrected on the basis of the stop-deciding time period, is used as a threshold value for deciding the stop of the wheels.  The wheel speed pulses, which are outputted just before the no-output time period, are outputted when the wheels are substantially stopped.  Thus, the time period corresponding to that pulse width is multiplied by the constant (2 1/2  + 1) that is the constant considering the deceleration and the mileage of the vehicle, to produce the optimum threshold value for deciding the wheel stop.  By deciding the wheel stop on the basis of the stop-deciding time period or the correction time period, therefore, the wheel stop can be promptly and precisely decided.  Thus, it is possible to improve the precision of the stop decision of the wheels.

Title: Centrifugal separator, rotor for centrifugal separator
Inventor: HASHIMOTO TOSHIHARU
IPC: B04B5/02
Filed: 2010-04-08
Abstract: The disclosed centrifugal separator attains both a simple attachment/detachment and a reliable fixing of a rotor to a rotating head. The disclosed rotor for a centrifugal separator is provided with male members and a rotor hole in which the rotating head is inserted. Each of the male members is rotatable around a rotating axle disposed horizontally within the rotor hole, has a center of gravity below the rotating axles, and has a protrusion on the opposite side of a rotating shaft that is below the center of gravity. The upper portion of the rotating head is a cylinder centered on the axle center of the rotating shaft, and is provided with a rotor connector, which has an annular concavity on the inner surface. When the rotor is disposed on the rotating head while the rotating shaft is in a stopped state, the male members are inside the rotor connector, and the protrusions of the male members are facing the concavity of the rotor connector. When the rotating shaft rotates, the protrusions can move to lock into the concavity. Also, force is applied to the protrusions in the direction of locking into the concavity when force is applied that would separate the rotor from the rotating head while the protrusion is locked into the concavity.
