    • In the construction of a damper assembly for musical instruments, the conventionally used swingable damper lever for operationally relating a key to an associated damper wire is omitted and the swing movement of the key is either directly and indirectly converted into a corresponding fairly vertical movement of an elongated damper holder via a balance weight disposed to the bottom end of the damper holder in order to avoid undesired influences caused by swinging movement of any mechanical parts. Use of a plate type damper holder further advantageously prevents undesirable twist and dancing of the damper holder. Simultaneous, even and well-controlled pressure contact of the damper head with the vibrating string assures ideal damping and acoustic effects and use of detachable balance weight enables free adjustment of touch on the key.
    • 在用于乐器的阻尼器组件的构造中,省略了常规使用的可操作地将钥匙与相关联的阻尼线相关联的可摆动阻尼器杆,并且钥匙的摆动运动被直接地和间接地转换成相应的相当垂直的运动 通过设置在阻尼器保持器的底端的平衡配重的细长阻尼器保持器,以避免由任何机械部件的摆动所引起的不期望的影响。 使用板式阻尼器支架进一步有利地防止阻尼器保持器的不期望的扭转和跳动。 阻尼头与振动弦的同时,均匀和良好的压力接触确保理想的阻尼和声音效果,并使用可拆卸的平衡重,可以自由调节钥匙上的触感。

    • A capstan device for taking up a braided wire in a braided wire manufacturing apparatus for braiding a plurality of wires to manufacture the braided wire. The capstan device includes a capstan roller having a tapered outer peripheral surface and provided with a flange portion on an end at a small diameter side thereof, and a guide member. The guide member has a first guide surface provided to be turned toward a large diameter side of the capstan roller in an axial direction of the capstan roller in a position on a larger diameter side than a portion having the smallest diameter in the tapered outer peripheral surface, and a second guide surface provided to be protruded from the first guide surface at an outer peripheral side of the tapered outer peripheral surface.
    • 一种用于在编织线制造装置中卷绕编织线的绞盘装置,用于编织多根线以制造编织线。 绞盘装置包括具有锥形外周面的主导辊,并且在其小直径侧的端部上设置有凸缘部分和引导构件。 引导构件具有第一引导表面,该第一引导表面设置成沿着主动轮的轴向方向朝向主动轮的大直径侧在比在锥形外周面中具有最小直径的部分更大直径侧的位置 以及设置成在锥形外周面的外周侧从第一引导面突出的第二引导面。
