A device is provided including a diaphragm for housing an object to be processed, and a fluid introducing passage to the vessel provided so that a greater part of a fluid flowing into the vessel flows into the diaphragm. The diaphragm can be formed of heat insulating material, and a filter can be provided for removing particles installed on the side of the diaphragm into which a fluid flows.
