Abstract

PURPOSE:To reduce a treating time with simple constitution by disposing cases for contg. materials to be treated in a thermostatic chamber and providing lead- in ports and discharge ports for an inert gas to these cases. CONSTITUTION:Cases 2 contg. plural pieces of objects 8 to be treated are disposed in a thermostatic chamber 1, and lead-in ports 3 and discharge ports 6 for an inert gas are provided on the side faces in the lower parts 2' of the cases 2. Then, when the inert gas is introduced into the chamber 1 through a lead- in port 5, the gas is introduced through the ports 3 into the vessel 2, whilst the inert gas discharged from the cases 2 is once discharged into the chamber 1 and is further discharged through the ports 6 to the outside of the chamber 1. The gaseous pressure in the cases is kept at >=2kg/cm<2> so as to prevent the inclusion of air from the outside.
