  • Publication number: 20210189006
    Abstract: The present invention relates to stable antibody-containing solution formulations in which aggregate formation of Emicizumab (ACE910) which is a bispecific antibody functionally substituting for FVIII, is suppressed. Specifically, the present invention relates to the above-mentioned antibody-containing solution formulations of pH 4.5 to 6.5 that contain the aforementioned bispecific antibody at 20 to 180 mg/mL, 10 mM to 40 mM histidine-aspartate buffer, Poloxamer 188 at 0.2 to 1 mg/mL, and 100 mM to 300 mM arginine.

  • Patent number: 9422904
    Abstract: Vehicle engine starting apparatus of automatically restarting an engine by quickly responding to a subsequent engine restart request even if engagement of a pinion gear with a ring gear is failed in the process of a stop of the engine. Pinion gear is displaced such that the pinion gear is engaged with the ring gear at a timing (when rotation speed of the pinion gear and rotation speed of the engine are nearly synchronized with each other with a signal from a control device when a predetermined condition is met. Where an engagement sensor has transmitted a signal “H” indicating engagement failure, when restart of the engine becomes necessary, the pinion gear is displaced toward a ring gear side by the control device.

  • Patent number: 6028381
    Abstract: Between a relay terminal of a direct current motor and a contact terminal of an electromagnetic switch, there is provided a fuse which is melted to cut off an electric current upon reaching a predetermined temperature. By properly setting the predetermined temperature at which the fuse melts, it is possible to make the fuse heated to a high temperature and melted in a relatively short time to cut off the electric current in the event of, for example, a continuous operative condition caused due to such a failure as fusion adhesion of a movable contact point with a B-terminal and an M-terminal or fusion adhesion of a contact point mechanism outside a starter, or an overcurrent supply condition caused upon a rotor being locked.

  • Patent number: 6006618
    Abstract: A starter motor has a rotating armature with a rotating shaft on which a groove is formed, a rear bracket, and a cylindrical-shape yoke connected to a front bracket which supports a pinion shaft. A holder washer member is inserted rotatively in the groove and limits movement in the axial direction of the rotating armature. A holder plate member is provided with a brush holder member. The holder washer member is sandwiched in an axial direction between a step portion of the rear bracket and an inner peripheral portion of the holder plate member. An outer peripheral edge portion of the holder plate member is sandwiched between an outer peripheral edge portion of the rear bracket and a step portion of the yoke. As a result, the rear bracket is fixed by a through-bolt to the front bracket. In the starter motor structure the holder plate member can be fixed to the rear bracket without using a fixing component such as a screw.

  • Patent number: 5969458
    Abstract: In a permanent magnet field starter motor, a ring shaped enlarged portion is formed at an end of a yoke and has an inner diameter Da which is larger than an inner diameter of the yoke. The inner diameter Da of the enlarged portion is at least as large as an outer diameter Db of a brush member holder plate which is inserted to an inner side of the enlarged portion, so that the radial position between the yoke and the brush member holder plate is directly aligned. A cut-out groove is formed on the yoke for inserting a bush member. The bush member is inserted into the cut-out groove, so that a thrust direction position of an outside portion lead wire, a lead terminal, and a lead wire is determined. A projection formed on the brush member holder plate has a width Wb which is at least as large as the width Wa of the cut-out groove. By inserting projection into the cut-out groove, the circumferential position between the yoke and the brush member holder plate is aligned.
