    • The invention relates to an electromotor comprising a stator part and a rotor part, which parts form an oil-containing spiral groove bearing system. Surface areas of said parts are provided with a so-called oil barrier in order to prevent the oil from creeping from the bearing system to the environment. According to the present invention, said oil barrier comprises a monolayer of perfluorocarboxylic acid anions, especially those having a chain length of 10-20 C-atoms and/or perfluoroalkylthiol anions. Oil barriers of this type can be easily provided on the rotor part and stator part by means of dipping. These oil barriers have a very small thickness and can very suitably be used to prevent oil creepage.
    • 本发明涉及一种电动机,其包括定子部分和转子部分,该部分形成含油螺旋槽轴承系统。 所述部件的表面区域设置有所谓的油屏障,以防止油从轴承系统爬行到环境中。 根据本发明,所述油屏障包括单层全氟羧酸阴离子,特别是链长为10-20个C原子和/或全氟烷基硫醇阴离子。 通过浸渍可以在转子部件和定子部件上容易地提供这种油屏障。 这些油屏障具有非常小的厚度,并且可以非常适合用于防止漏油。

    • The invention relates to an opto-electronic coupler comprising an optical transmitter and an optical receiver which are secured to separate connection conductors and which are electrically connected to one or more connection conductors via contact wires, the transmitter, the receiver, the contact wires and parts of the connection conductors being embedded in a primary, enveloping body, and said primary enveloping body being embedded in a secondary, non-transparent enveloping body. Couplers having a high breakdown voltage and a low percentage of rejects are obtained if the interface between the primary enveloping body and the secondary enveloping body comprises at least one zone in which the primary and the secondary enveloping bodies are adhesively interconnected, and if the interface also comprises at least one zone in which the primary and the secondary enveloping bodies are interconnected in a non-adhesive manner.
    • 本发明涉及一种光电耦合器,包括光发射器和光接收器,它们被固定到单独的连接导体上,并通过接触线,发射器,接收器,接触导线和部件电连接到一个或多个连接导体 所述连接导体嵌入在初级包封体中,并且所述初级包络体嵌入在次级不透明的包封体中。 如果初级包络体和次级包封体之间的界面包括至少一个区域,其中初级和次级包封体粘合地相互连接,并且如果界面也是这样,则获得具有高击穿电压和低百分比的废品的耦合器 包括至少一个区域,其中主要和次要包封体以非粘合的方式相互连接。
