Abstract: A drive device includes a first bearing lubricated by a fluid and a second bearing lubricated by a lubricant having a higher electrical conductivity than the fluid. The first bearing rotatably supports a shaft extending in the axial direction along the rotation axis. A housing of the drive device has a first bearing holder that holds the first bearing. The second bearing is arranged between the shaft and the housing and rotatably supports the shaft. The second bearing is arranged in a space isolated from the first bearing holder.

Abstract: The invention has disclosed a method for transforming interactive source documents organized in a hierarchy of nested cells to web pages. The method includes: directly mapping the elements of static cells in source documents to web pages so as to enable the transformation of the elements of static cells in source documents to web page elements; selecting the dynamic cells which are to be transformed from the source documents; adding the cell level tags or comments for the selected dynamic cells, and then adding the element level tags or comments for the selected dynamic cells, so as to construct the mapping relationship between the elements of dynamic cells and the corresponding elements of web pages; transforming the elements of dynamic cells to corresponding elements of web pages according to the constructed mapping relationship.
