| Research Abstract |
Conventional vacuum compatible non-contact guideway systems have used aerostatic bearings with several steps of seals using vacuum pumps. Accordingly, these systems require relatively large space for seals and several vacuum pumps. Therefore, in this study, we proposed hydrostatic guideway systems using ionic liquid instead of aerostatic guideway systems. The proposed system does not need any seal systems to maintain vacuum, which makes the guideway system for a vacuum chamber simple and small. We developed a hydrostatic rotational spindle and a hydrostatic linear guideway table using ionic liquid and confirmed the usefulness of the proposed guideway system.
