    • A silencer for attenuating a sound includes an inner duct in which gas flows, and an outer duct surrounding the inner duct with a gas layer formed between the outer duct and the inner duct. The sound is generated in one of an upstream side of the inner duct in a gas flow direction, a downstream side of the inner duct in the flow direction, and an inside of the inner duct. The inner duct includes a thin film over its entire surface. The film has a first reinforcement section formed in a direction parallel to the flow direction, and a plurality of vibrating surfaces. The film is bent at the first reinforcement section. Each combination of adjacent two of the plurality of vibrating surfaces is connected by the first reinforcement section. The first reinforcement section of the inner duct is fixed to the outer duct.
    • 用于衰减声音的消声器包括气体流过的内部管道和围绕内部管道的外部管道,其中外部管道和内部管道之间形成有气体层。 声音在内管道的上游侧,气流方向,内管的流动方向的下游侧,内管的内部产生。 内部管道在其整个表面上包括薄膜。 薄膜具有沿与流动方向平行的方向形成的第一加强部和多个振动面。 胶片在第一个加强部分弯曲。 多个振动表面中的相邻两个的每个组合通过第一加强部连接。 内管的第一加强段固定在外管上。

    • A stator for an electric rotating machine includes a hollow cylindrical stator core and a stator coil made up of a plurality of electric wires mounted on the stator core. The stator core has a plurality of slots that are formed in a radially inner surface of the stator core and spaced at predetermined intervals in the circumferential direction of the stator core. The stator core also has a plurality of tooth portions each of which is formed to radially extend between one circumferentially-adjacent pair of the slots. Moreover, the stator core further has a plurality of displacement restricting portions each of which is formed, as an integral part of the stator core, on an axial end face of a corresponding one of the tooth portions of the stator core to restrict displacement of the stator coil relative to the stator core.
    • 旋转电机的定子包括中空圆柱形定子芯和由安装在定子芯上的多根电线构成的定子线圈。 定子铁芯具有形成在定子铁芯的径向内表面中并沿定子铁芯的圆周方向以预定间隔隔开的多个槽。 定子芯还具有多个齿部,每个齿部形成为在一个周向相邻的一对槽之间径向延伸。 此外,定子铁芯还具有多个位移限制部,每个位移限制部分作为定子铁心的整体部分形成在定子铁芯的对应的一个齿部的轴向端面上,以限制定子铁芯的位移 定子线圈相对于定子芯。
