    • An improper communication detection system that acquires packets that are circulated through a plant network by mirroring and detects improper communication includes a storage unit configured to prestore a session whitelist, which is a list of sessions that can be generated in the plant network; a session determination/separation unit configured to make a determination as to a success or failure of session approval on the basis of the acquired packet and configured to generate session information indicating an approved session; and a first improper communication detection unit configured to compare the session information generated by the session determination/separation unit with the session whitelist, and configured to detect communication related to the relevant session as improper communication when the session information does not match any session in the session whitelist.
    • 通过镜像和检测不正当通信来获取通过工厂网络流通的分组的不正当通信检测系统包括:配置为预先存储可以在工厂网络中生成的会话列表的会话白名单的存储单元; 会话确定/分离单元,被配置为基于所获取的分组来确定关于会话批准的成功或失败,并且被配置为生成指示批准会话的会话信息; 以及第一不正当通信检测单元,被配置为将由会话确定/分离单元生成的会话信息与会话白名单进行比较,并且被配置为当会话信息不匹配任何会话时,检测与相关会话相关的通信作为不正确的通信 会话白名单。

    • In a rolling bearing including an oil supply unit for supplying lubricating oil stored in a tank by a pump via a nozzle which is made to open in an annular space defined between an inner ring and an outer ring, the nozzle is made to open in a space between an inner circumferential surface of a case and the inner ring, and the inner circumferential surface of the cage is formed into a surface in which an inside diameter of the cage is reduced gradually in a continuous or intermittent fashion from an axial center portion towards at least an end portion lying on a side where the nozzle is inserted, whereby a lubricating oil dropped on to the inner circumferential surface of the cage is caused to flow towards the axial center portion by virtue of centrifugal force generated by the rotation of the cage, so as to prevent the lubricating oil from flowing out to the outside of the bearing unit.
    • 一种滚动轴承,其特征在于,具有供油单元,所述供油单元用于经由喷嘴供给由罐内容纳的润滑油,所述喷嘴在形成于内圈和外圈之间的环状空间内开口,使得所述喷嘴在 壳体的内周面与内圈之间的空间与保持架的内周面形成为从轴心部向连续或间歇方向逐渐减小保持架的内径的面 至少一个位于喷嘴插入一侧的端部,由于通过所述保持架的旋转产生的离心力,使在所述保持架的内周面上滴下的润滑油向所述轴向中心部流动 ,以防止润滑油流出到轴承单元的外部。
