    摘要: The invention concern an apparatus and a method for manufacturing polycrystalline silicon having a reduced amount of boron compounds. The invention feeds Ar gas in a trichlorosilane line, which connects a trichlorosilane (TCS) tank and a series of distillation units. The distillation units have a pressure transducer and a pressure independent control valve (PIC-V) positioned on a vent gas line for discharging vent gas from the distillation units. Ar gas is fed to the TCS line with higher pressure than the pressure set for opening the PIC-V. The TCS is distilled by the distillation units with continuously discharging vent gas from the distillation units.

    摘要: In order to estimate a magnetic pole position of a permanent magnet type brushless motor, the following steps are conducted. A given &ggr; axis and a given &dgr; axis in an advanced from the &ggr; axis by an electrical angle of 90° are set. A closed-loop electric current control system in the &ggr; axis direction is formed while forming an open-loop electric current control system in the &dgr; axis direction. It is calculated an interference current generating in the &dgr; axis direction when a current command in the &ggr; axis direction is given as a stepwise alternating current command. The &ggr; axis is finely advanced by an angle of &Dgr;&thgr; when a sign of a product of an integral value of the interference current and a value of the current command in the &ggr; axis direction is positive. Alternatively, the &ggr; axis is finely delayed by an angle of &Dgr;&thgr; when the sign is negative. Thereby, the &ggr; axis is made accord with either a d axis as a true magnetic axis or with a -d axis advanced by 180° from the true magnetic axis.
