    • Disposed is a jet mill that has a cylindrical pulverization chamber (10) and a classification chamber (6) that connects to the pulverization chamber (10). A fine-powder discharge port (4a) and a classification rotor (7) are provided in the classification chamber (6). A feedstock supply port (5) and at least one gas emission nozzle (11) are provided in the pulverization chamber (10). The shape of the classification chamber (6) is a cone that starts on the inner wall of the pulverization chamber (10), and is angled towards the classification rotor (7). This configuration gives the jet mill high efficiency of pulverization and reduces the amount of powders left in the chamber when the jet mill has finished running.
    • 设置有具有连接到粉碎室(10)的圆柱形粉碎室(10)和分级室(6)的喷射式粉碎机。 在分级室(6)中设置有细粉末排出口(4a)和分级转子(7)。 原料供给口(5)和至少一个排气喷嘴(11)设置在粉碎室(10)中。 分级室(6)的形状是从粉碎室(10)的内壁开始朝向分级转子(7)倾斜的锥体。 这种配置给喷射磨机提供了高效率的粉碎,并且当喷射磨机运行完毕时,减少了腔室中留下的粉末的量。

    • An optical waveguide includes a first waveguide region and a second waveguide region. The first waveguide region includes a first core, a first clad provided around the first core, and a light reflecting surface. The light reflecting surface has at least one function of (i) reflecting light from a longitudinal direction of the first core toward a direction crossing the longitudinal direction and (ii) reflecting light from the crossing direction toward the longitudinal direction of the first core. The second waveguide region continues from the first waveguide region. The second waveguide region that includes a second core, and a second clad provided around the second core. The second core of the second waveguide region is thinner than the first core of the first waveguide region. A total thickness of the second core and the second clad is smaller than that of the first core and the first clad.
    • 光波导包括第一波导区域和第二波导区域。 第一波导区域包括第一芯,围绕第一芯设置的第一包层和光反射表面。 光反射面至少具有以下功能:(i)将反射来自第一芯的纵向的光朝向与长度方向交叉的方向反射,以及(ii)将来自交叉方向的光朝向第一芯的长度方向反射。 第二波导区域从第一波导区域继续。 包括第二芯的第二波导区域和围绕第二核心设置的第二覆层。 第二波导区域的第二核心比第一波导区域的第一核心薄。 第二芯和第二包层的总厚度小于第一芯和第一包层的总厚度。
