    • Proposed is an improvement in the method and single crystal growing chamber for the preparation of a single crystal rod of silicon by the Czochralski method, according to which the distance between the surface of the melt of silicon contained in a crucible and the lower surface of the top wall of the crystal growing chamber is equal to or larger than the diameter of the crucible and the heat-insulating cylinder surrounding the crucible containing the melt of silicon and the heater has such a height as to reach the lower surface of the top wall of the chamber so as to keep the single crystal rod under growing is kept at a temperature not lower than 700.degree. C. until reaching the lower surface of the top wall of the chamber thereby decreasing the density of the crystal defects of BMD type in the seed end of the single crystal rod as grown so that the uniformity in the distribution of BMD density is increased throughout the single crystal rod.
    • 提出了通过切克劳斯基法(Czochralski method)制备单晶硅的方法和单晶生长室的改进,根据该方法,坩埚中包含的硅熔体表面与坩埚的下表面之间的距离 晶体生长室的顶壁等于或大于坩埚的直径,并且包含硅和加热器的熔体的坩埚周围的隔热圆筒具有如下高度:到达顶壁的下表面 保持单晶棒生长的室保持在不低于700℃的温度,直到到达室的顶壁的下表面,从而降低种子中BMD型晶体缺陷的密度 生长的单晶棒的端部,使得在整个单晶棒中BMD密度分布的均匀性增加。

    • An automatic power generation type flowmeter generates a measuring signal through measuring of a flow rate of fluid flowing through a passage and transmits it to a receiver at a remote location. The flowmeter includes a power generator coupled to a detection shaft rotated under an action of a fluid flowing through the passage and outputting an electric signal. The power generator includes a permanent magnet having S- and N-poles, an electromagnetic coil having a core around its axis and arranged adjacent to the magnet with the axis of the coil located in a direction substantially perpendicular to a rotation shaft, a first stator magnetically coupled to the core and having its magnetic induction portion arranged opposite to the N-pole of the magnet, and a second stator magnetically connected to the core and having its magnetic induction portion arranged opposite to the S-pole of the magnet.
