    • An immunoassay comprisingimmobilizing antibody in a matrix for electrophoresis;immobilizing antigen in a measurement sample by subjecting the same to antigen antibody reaction with the above-mentioned immobilized antibody by a procedure of moving the antigen by electrophoresis;either moving labeled antibody to the above-mentioned immobilized antigen by electrophoresis to react the same with the immobilized antigen, or moving labeled antigen to the unreacted portion of the above-mentioned immobilized antibody by electrophoresis to react the same with the unreacted portion; andmeasuring the concentration of antigen in the sample, characterized byusing as a label for the labeled antibody or the labeled antigen an enzyme capable of coverting a substrate into a fluorescent substance,moving the substrate convertible into a fluorescent substance by said enzyme by electrophoresis,reacting the substrate with the label enzyme to convert the same into a fluorescent substance, andmeasuring the concentration of the fluorescent substance in the electrolyte solution.
    • 免疫测定法,其包括将抗体固定在用于电泳的基质中; 通过使抗原通过电泳移动的方法,将抗原固定在测量样品中,使其与上述固定化抗体进行抗原抗体反应; 通过电泳将标记抗体移动到上述固定化抗原上,使其与固定化抗原反应,或通过电泳将标记的抗原移动到上述固定化抗体的未反应部分,使其与未反应部分反应; 测定样品中的抗原浓度,其特征在于,将标记抗体或标记抗原的标记作为能够将底物覆盖成荧光物质的酶,通过电泳将所述酶转化为荧光物质, 使底物与标记酶反应,将其转化为荧光物质,并测量电解质溶液中荧光物质的浓度。

    • A welding gun precludes moisture from penetrating inside of a motor housing due by preventing development of negative pressure inside the motor housing. The welding gun includes a feed screw mechanism that is coupled to a servo motor and has a hollow rod that reciprocally moves in a predetermined direction by way of torque applied by the servo motor, and a moveable electrode tip that is connected to a leading end portion of the hollow rod and opens and closes relative to a fixed electrode tip according to the reciprocal movement of the hollow rod. The servo motor has a motor housing in which a motor housing hollow part accommodating a portion of the hollow rod to be reciprocally moveable is formed. A vent that ventilates the motor housing hollow part with ambient air is formed in the motor housing.
    • 由于防止电动机壳体内的负压发展,焊枪防止湿气渗透到电动机壳体的内部。 焊枪包括一个联接到伺服电动机的进给螺杆机构,并具有通过由伺服电机施加的扭矩沿预定方向往复运动的中空杆,以及可移动电极头,其连接到前端部分 并且根据中空杆的往复运动相对于固定的电极头开启和关闭。 伺服电动机具有马达壳体,其中形成容纳中空杆的一部分以可往复运动的中空部分的马达。 在电机壳体内形成有通风环境空气的电机壳体中空部分的通风口。
