Title: Method and apparatus for cleaning metal workpiece
Inventor: BUERUNAA KOMANZU
IPC: B08B3/10
Filed: 1992-11-17
Abstract: A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50 DEG  C. and 90 DEG  C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

Title: Vacuum heating dryer
Inventor: MITANI KENJI
IPC: F26B25/16
Filed: 1993-12-27
Abstract: PURPOSE:To enable employing a material of minor strength for forming a holding container with a small wall thickness by approximating the container in shape to a polyhedron with every facet as a plane and forming at least one of the facets in a shape having an outwardly convex curvature. CONSTITUTION:A structure (holding container) composed of an inner container 8 and an inner-container lid 2 is formed in a shape approximating a rectangular parallelepiped and each facet with an outwardly convex curvature. As a result, the external pressure (usually in the proximity of the atmospheric pressure) bearing on each facet of the inner container 8 can be scattered to some extent in tangential directions at any point on each facet. When each facet has an ideal curvature, the external pressure bearing on each facet is mostly scattered in tangential directions and the force exerted on each facet mostly works as a compressive force on the material constituting the facet. Therefore, a material of minor strength permits the wall thickness to be small.
