ABSTRACT:
A vacuum-oriented vertical transfer system which provides super vacuum/super clean environments, and a gate valve assembly which reduces the size of electromagnet sections. The vacuum-oriented vertical transfer system includes a cylindrical partition wall, and a rod vertically moved through an open bottom of a vacuum container. The rod is floatingly supported in radial and axial directions thereof by a radial magnetic support device and an axial magnetic support device, respectively. The gate valve assembly comprises a closure member mounted for positioning adjacent to and away from a port of a container to close and open the port, respectively. A neck member is integrally connected to the closure member and is mounted for movement to position the closure member to open and close the port of the container. A radial magnet device levitates the neck member by magnetic forces in a radial direction thereof. An axial magnetic device levitates the neck member by magnetic forces in an axial direction thereof. A moving mechanism moves the neck member to position the closure member to open and close the port of the container.
