    • A damper disk comprises a pair of side plates at both sides of a flange of a hub splined to an output shaft. Both side plates and the flange are connected each other through torsion springs. One or a pair of sub-plates are disposed between the flange and the side plates. Both side plates are connected together by a stop pin which extends through notches in the flange and the sub-plates. The notches in the sub-plates are shorter than the notch in the flange. Frictional force between the flange 2 and the sub-plate is set stronger than that between the side plates and sub-plates. According to the invention, hysteresis torque changes during torsional operation, thereby, noises during idling of the engine as well as acceleration can be prevented.
    • 阻尼盘包括在花键连接到输出轴的轮毂的凸缘的两侧的一对侧板。 两个侧板和法兰通过扭转弹簧相互连接。 一个或一对子板设置在凸缘和侧板之间。 两个侧板通过止动销连接在一起,该止动销延伸穿过法兰和子板中的凹口。 子板中的凹口比凸缘中的凹口短。 凸缘2和副板之间的摩擦力设定得比侧板和副板之间的摩擦力强。 根据本发明,在扭转操作期间,滞后扭矩变化,从而可以防止在发动机怠速期间的噪声以及加速度。

    • A sewing machine including a needle bar; a sewing needle attached to the lower end of the needle bar; a needle bar drive mechanism vertically driving the needle bar; a presser foot capable of applying releasable pressure on a workpiece cloth and that releases the pressure to allow manual movement and sewing of the workpiece cloth; a regulatory needle including a tip and being capable of assuming a pierced state where the tip is pierced through the workpiece cloth and a non-pierced state, wherein the regulatory needle is moved along with the workpiece cloth while retaining the pierced state of the tip; a regulatory needle drive unit vertically driving the regulatory needle between the pierced state and the non-pierced state in coordination with vertical movement of the sewing needle; and a regulatory needle regulator limiting horizontal movement of the regulatory needle so as not to exceed a predetermined stitch pitch.
    • 一种缝纫机,包括针杆; 针刺针的下端附着缝纫针; 针杆驱动机构,垂直地驱动针杆; 压脚能够在工件布上施加可释放的压力,并且释放压力以允许工件布的手动移动和缝合; 包括尖端的调节针,并且能够假设刺穿状态,其中尖端穿过工件布和未穿刺状态,其中调节针与工件布一起移动,同时保持尖端的刺穿状态; 调节针驱动单元与缝纫针的垂​​直运动协调地垂直地将调节针施加在刺穿状态和非穿刺状态之间; 以及调节针调节器,其限制调节针的水平移动,以便不超过预定的针距。
