    • In a process for producing a phenolic compound which comprises treating an aralkyl hydroperoxide with a mineral acid to cleave it to phenolic compound and a ketone, neutralizing or removing the mineral acid, feeding the resulting acid cleavage mixture containing the salt to a distillation column, distilling it therein to separate it into an overhead fraction consisting mainly of the ketone and a bottom fraction consisting mainly of the phenolic compound, and recovering the phenolic compound from the bottom fraction; the improvement which comprises withdrawing a liquid layer from a site of feeding the acid cleavage mixture in the distillation column or from a site below it but above the bottom of the distillation column, subjecting the liquid layer to an oil-water separating means, recycling the separated oil layer to a site below said site of withdrawal, optionally feeding a hydrocarbon having a lower boiling point than the phenolic compound but a higher boiling point than the keton and/or water to the distillation column, and recovering the phenolic compound from the bottom fraction whose salt content has thus been reduced.
    • 在制备酚类化合物的方法中,其包括用无机酸处理芳烷基氢过氧化物以将其切割成酚类化合物和酮,中和或除去无机酸,将所得到的含有该盐的酸裂解混合物进料到蒸馏塔中,蒸馏 在其中将其分离成主要由酮和主要由酚类化合物组成的底部馏分组成的塔顶馏分,并从底部馏分回收酚类化合物; 该改进包括从蒸馏塔中的酸裂解混合物的供给部位或从蒸馏塔下方但位于蒸馏塔底部的位置排出液体层,使液体层进入油水分离装置,循环利用 将分离的油层分离到所述抽出位点下方的位置,任选地将比酚类化合物低的沸点的烃与比蒸馏塔的酮和/或水进料的沸点高,并从底部回收酚类化合物 因此其盐含量已经降低的馏分。

    • A motor having a stator and a rotor housed in a U-shaped cylindrical case. The cylindrical case has a connector bushing fitted at one end, and an opening at the other. Located on the periphery of the opening is a cylindrical support that projects inside the cylindrical case. A ball bearing is fitted inside the cylindrical support. A shaft is inserted into the opening and one end of the shaft is supported in the bearing. The other end of the shaft is supported in another bearing, which in turn, is mounted in a bearing bushing housed in the cylindrical case. One end of the stator touches a step of the inner circumference of the case, thereby fixing the position of the stator in the axial direction. One end of the inner circumference of the stator is fitted to an outer circumference of the cylindrical support, thereby fixing its position in the radial direction. Two rotor cores are mounted on the shaft. The gap between the stator core and the rotor cores is approximately 40-50 microns. The connector is integrated with the connected bushing.
    • 具有定子和转子的电动机容纳在U形圆柱形壳体中。 圆筒形壳体具有一端安装的连接器衬套和另一端的开口。 位于开口周边的是一个圆柱形的支撑件,突出在圆柱形壳体内。 圆柱形支架内装有一个滚珠轴承。 轴插入开口中,轴的一端支撑在轴承中。 轴的另一端支撑在另一个轴承中,另一个轴承又安装在容纳在圆筒形壳体中的轴承衬套中。 定子的一端接触壳体的内周的台阶,从而固定定子的轴向位置。 定子的内圆周的一端装配在圆柱形支撑件的外圆周上,从而将其定位在径向方向上。 两个转子芯安装在轴上。 定子芯和转子芯之间的间隙约为40-50微米。 连接器与连接的衬套集成。

    • A stepping motor having a rotor that includes a magnetic component whose circumferential part is magnetized in multipole along the circumferential surface thereof, the stepping motor being capable of forcing the rotor to rotate by magnetic force provided between magnetic poles of the rotor and excited salient poles of a stator, in which the magnetic component includes two magnetic component portions each shaped as an approximate ring, and the two magnetic component portions are either combined with each other or set up separately at an appropriate spacing between them. The stepping motor is capable of rotating with not only high speed but also less undesired vibration and noises, and enabling a simpler, smaller manufacturing equipment thereof to be constructed.
    • 一种步进电动机,其具有转子,该转子包括其周向部分沿着其圆周表面被多次磁化的磁性部件,所述步进电动机能够通过设置在转子的磁极和激励的凸极之间的磁力来迫使转子旋转 一个定子,其中磁性部件包括两个形成为大致环的磁性部件部分,并且两个磁性部件部分彼此组合或者以它们之间的适当间隔分开设置。 步进电动机不仅可以高速旋转,而且可以减少不希望的振动和噪音,并能够构建更简单,更小的制造设备。
