    • Wafer disk holds wafers in position by centrifugal force and its rotating shaft is supported by a bearing capable of magnetic levitation that has a thrust bearing and radial bearings. An annular groove providing a heat radiating zone is formed under the wafer receiving faces of the wafer disk. A cooling plate cooled to a temperature not exceeding the temperature of liquid nitrogen is inserted into the groove in a contactless manner so that the wafer disk is cooled by heat radiation. In the absence of any area of physical contact in the mechanisms for axially supporting and cooling the wafer disk, ions can be implanted in low dose into wafers on the fast rotating disk while improving the quality of wafers after implantation. Further, no triboelectricity will develop, thereby contributing to an improvement in the precision of ion beam current measurement.
    • 晶圆盘通过离心力将晶片保持在适当位置,其旋转轴由具有推力轴承和径向轴承的磁悬浮轴承支撑。 在晶片盘的晶片接收面的下方形成设置散热区的环状槽。 将冷却至不超过液氮温度的冷却板以非接触的方式插入槽中,从而通过热辐射冷却晶片盘。 在用于轴向支撑和冷却晶片盘的机构中没有任何物理接触区域的情况下,可以将离子以低剂量注入快速旋转盘上的晶片中,同时改善植入后晶片的质量。 此外,不会产生摩擦电,从而有助于提高离子束电流测量的精度。

    • New .omega.-(N-acylamino)alkylphosphoryl ethanolamines and their pharmaceutically acceptable acid addition salts have superior renin-inhibitory activities, antihypertensive activities and cholesterol-lowering activities. The .omega.-(N-acylamino)alkylphosphoryl ethanolamines are prepared by (1) reacting an .omega.-(N-acylamino) alkanol with a 2-(N-substituted amino)ethyl phosphate or its derivative, hydrolyzing the resulting product or splitting off the phosphoric acid-protective group of the resulting product thereby to form an .omega.-(N-acylamino) alkyl 2-(N-substituted amino) ethyl phosphate, and splitting off the amino-protective groups of the resulting phosphate, or (2) reacting an .omega.-(N-acylamino) alkanol with a phosphorus oxyhalide, reacting the resulting .omega.-(N-acylamino)alkyl dichlorophosphate with a 2-(N-substituted amino) ethanol, hydrolyzing the reaction product to form an .omega.-(N-acylamino) alkyl 2-(N-substituted)ethyl phosphate, and splitting off the amino-protective groups of said phosphate.
