    • The present invention relates to a continuous shear deformation device. In order to occur shear deformation at the position at which a material is inserted into a molding path from a rotary guide apparatus for the purpose of solving the problem that the amount of shear deformation of a material is non-uniform and insufficient due to the gap between the curved portion of the molding path and the lower parts of the material, there is provided a continuous shear deformation device, characterized in that a curved portion is constructed by collaboration between the rotary guide apparatus and the molding path. In addition, there are provided additional constructions for effectively performing shear deformation by a small power by reducing the friction at the molding path excepting the curved portion. The present invention thusly constructed can be utilized for continuously and effectively mass-produce sheared materials.
    • 本发明涉及连续剪切变形装置。 为了解决材料的剪切变形量由于间隙而不均匀和不足的问题,为了在从旋转引导装置插入到模制路径中的位置处发生剪切变形 在模制路径的弯曲部分和材料的下部之间提供连续的剪切变形装置,其特征在于,通过旋转导向装置和模制路径之间的协作构造弯曲部分。 此外,还提供了通过减小​​除了弯曲部分之外的模制路径处的摩擦力来通过小功率有效地执行剪切变形的附加结构。 这样构造的本发明可以用于连续且有效地大量生产剪切材料。

    • Disclosed is a device for sensing the opening degree of a valve, which can easily determine the upper and lower limits without using upper and lower limit switches so that, besides simplifying the mechanical structure, the device can be easily installed, maintained, and repaired. The device can avoid basic errors and improve the opening degree sensing performance without using upper and lower limit switches, cams, and a spline so that, by simplifying the mechanical structure, the device can be manufactured, installed, maintained, and repaired at a low cost, and its long-term durability is improved. The device has a main gear adapted to disengage from the meter gear when the main gear is rotated excessively so that any damage to the meter gear and potentiometer, which may occur during installation or use, is prevented.
    • 公开了一种用于感测阀的开度的装置,其可以容易地确定上限和下限而不使用上限和下限开关,使得除了简化机械结构之外,装置可以容易地安装,维护和修理。 该装置可以避免基本误差,并且不使用上下限开关,凸轮和花键来提高开度感测性能,从而通过简化机械结构,可以以低的速度制造,安装,维护和维修设备 成本,其长期耐久性得到改善。 当主齿轮过度旋转时,该装置具有适于与仪表齿轮脱离的主齿轮,从而防止在安装或使用期间可能发生的对仪表齿轮和电位计的任何损坏。
