    • In an apparatus for trapping and killing insects using an electric discharge between electrodes to count and/or kill insects or the like, the present invention presents a technology to almost certainly count and/or kill the insects or the like even when the applied voltage is set low. In an insect-trapping/killing apparatus as an embodiment of the invention, when an insect or the like enters the space between an outer electrode and a central electrode, an electric discharge passes through the insect or the like, whereby the insects or the like is killed. After that, the central electrode is rotated in a preset direction to remove the insect or the like downwards by the frictional force. Since the removing mechanism as described above solves the problem of the clogging of the space between electrodes by the insect or the like, the distance between the electrodes can be set as small as the size of the body of the insect or the like, and the applied voltage can be set accordingly low.
    • 在使用电极之间的放电捕获和杀死昆虫以计数和/或杀死昆虫等的装置中,本发明提供了几乎肯定地计数和/或杀死昆虫等的技术,即使施加的电压是 设置低。 在作为本发明的一个实施例的昆虫捕获/杀死装置中,当昆虫等进入外部电极和中心电极之间的空间时,放电通过昆虫等,从而昆虫等 被杀害 此后,中心电极沿预设方向旋转,以通过摩擦力向下移除昆虫等。 由于如上所述的除去机构解决了昆虫等之间的电极之间的空间堵塞的问题,所以电极之间的距离可以设定为与昆虫等的身体的尺寸一样小,并且 施加电压可以相应地设置为低。

    • A silicon melting crucible having a double structure, in which a quartz crucible is inserted inside of a carbon crucible, is provided with devices for preventing deformation, such as turning-down, buckling and bending at an upper portion of the quartz crucible, or invasion of an SiO gas into a space between the quartz crucible and the carbon crucible during pulling up of a silicon single crystal. According to one form of the invention an upper portion of the quartz crucible has a frusto-conical inclined portion with an angle of inclination desirably of from 5.degree. to 40.degree.. According to another form of the invention a carbon ring having a cross section of either L-shape or U-shape is applied to the upper portion of the quartz crucible and the carbon crucible.
    • 具有将石英坩埚插入碳坩埚内部的双重结构的硅熔融坩埚设置有用于防止在石英坩埚的上部处的变形(例如倒塌,弯曲和弯曲)或入侵的装置 的SiO气体在硅单晶提拉期间进入石英坩埚和碳坩埚之间的空间。 根据本发明的一种形式,石英坩埚的上部具有倾斜角度为5°至40°的截头圆锥形倾斜部分。 根据本发明的另一种形式,将具有L形或U形截面的碳环施加到石英坩埚和碳坩埚的上部。
