    • A drive motor for an electrically powered automotive vehicle is provided which includes a motor stator including a magnetic body and coils. The inner peripheral surface of the magnetic body has a plurality of teeth protruding therefrom, around which the coils are wound. The drive motor also includes a motor housing mounted to an outer periphery of the motor stator to retain the motor stator. The outer peripheral surface of the magnetic body includes cutout portion(s) formed at circumferential location(s) thereof, with the circumferential location(s) being at the same phase as those of the teeth. An inner peripheral surface of the motor housing includes engagement portion(s) formed at circumferential location(s) thereof, with the circumferential location(s) being opposed to the cutout portion(s). The engagement portion(s) is/are engageable with the cutout portion(s). The engagement portion(s) and the cutout portion(s) cooperate with each other to form arresting unit(s) for arresting the motor stator.
    • 提供了一种用于电动机动车辆的驱动电机,其包括具有磁体和线圈的电动机定子。 磁性体的内周面具有从其突出的多个齿,卷绕线圈。 驱动电动机还包括安装到电动机定子的外周以保持电动机定子的电动机壳体。 磁体的外周面包括形成在其周向位置的切口部分,其周向位置与齿的相位相同。 马达壳体的内周面包括形成在其周向位置的接合部分,其周向位置与切口部分相对。 接合部分可以与切口部分接合。 接合部分和切口部分彼此协作以形成用于阻止电动机定子的止动单元。

    • The present invention provides a dental composition exhibiting both an excellent light diffusion property and excellent transparency, and having high mechanical strength and surface smoothness and gloss after polishing as a cured product and good handling properties as a paste. The present invention is a dental composition including: a polymerizable monomer (A); and an amorphous powder (B). The amorphous powder (B) has an average particle size of 1 to 20 μm, and includes silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The difference in refractive index between the cured product of the polymerizable monomer (A) and the amorphous powder (B) is 0.005 to 0.03.
    • 本发明提供了具有优异的光扩散性和优异的透明性,具有高的机械强度和表面光滑度以及作为固化产物的抛光后的光泽度和作为糊剂的良好的操作性能的牙科用组合物。 本发明是一种牙科用组合物,其含有:聚合性单体(A) 和无定形粉末(B)。 无定形粉末(B)的平均粒径为1〜20μm,包括二氧化硅系微粒和覆盖二氧化硅系微粒表面的氧化物的涂层。 氧化物含有锆原子,硅原子和氧原子。 聚合性单体(A)的固化物与非晶质粉末(B)的折射率的差为0.005〜0.03。
