Abstract: A composition containing antithrombin and a method for treating preeclampsia are disclosed. The method includes administering antithrombin or a composition including antithrombin to a subject in need of preeclampsia treatment. The subject may have blood antithrombin activity of 100% or less. The composition containing antithrombin may be administered to a subject with preeclampsia, who has blood antithrombin activity of 100% or less and the like.

Abstract: To provide a rolling bearing which is superior in preventing electrolytic corrosion, suitable for use in applications where torque reduction of the bearing is required by reducing an amount of lubricant used or by using a lubricant having a low viscosity, and has superior acoustic characteristics and durability, a rolling element according to the present invention is made of an alumina-zirconia composite material including an alumina component and either a zirconia component or a yttria-zirconia component containing 1.5 to 5 mol % of yttria, a mass ratio of the alumina component to the zirconia component or the yttria-zirconia component being 5:95 to 50:50.

Abstract: An electric current control method for a servomotor in which a reactive current is lowered in a region where a voltage saturation does not occur, to suppress generation of heat caused by the reactive current and achieve a stable rotation up to a high-speed region. In the current control of the servomotor using a DQ conversion, an electric current is not supplied to d-phase and supplied only to q-phase when a rotational speed of the servomotor is not high, and the reactive current is supplied to the d-phase only when the rotational speed of the servomotor is high, to thereby lower the terminal voltage of the servomotor by the reactive current. Thus, the reactive current is reduced in the region where the voltage saturation does not occur, to thereby suppress the generation of heat due to the reactive current, and also achieve the stable rotation even in the high-speed region.

Abstract: A hollow shaft motor which has a ball screw shaft (24) passed therethrough and which drives the ball screw shaft (24) to rotate, wherein provision is made for flow paths (28, 30, 32) for passing compressed air for cooling purposes to one end of the motor so that the heat generated by the motor is not conducted to the ball screw shaft (24) through the ball nut (22) attached to one end of the cylindrical shaft (20) of the through type motor and engaged with the ball screw shaft.
