Abstract: A high efficient stirling engine with excellent thermal efficiency, which can increase the heating temperature of a high temperature section, is obtained by preventing the heat from being lost in a member connecting the high temperature section and a low temperature section. The high temperature section 5 and the member (a regenerator housing 16) connecting the high temperature section and the low temperature section are formed to have a split configuration by using different materials for the each, in which the high temperature section 5 is formed of a heat resistant/high heat conductive material having high heat resistance property and high heat conductivity, the regenerator housing 16 connecting the high temperature section 5 and the low temperature section 7 is formed of a heat resistant/low heat conductive material having low heat conductivity, and the both are bonded integrally to each other to obtain an integral sealed structure.

Abstract: An ozone beam generation apparatus includes an ozonizer for forming an ozone-containing gas through the ozonization of an oxygen-containing gas; a refrigerator for liquefying or solidifying only ozone present in the ozone-containing gas; a vessel for storing the liquefied or solidified ozone; a temperature controller for contorting the temperature of the storing vessel and for gasifying the liquefied or solidified ozone; and a piping system for transporting-the gasified ozone to a desired device. The apparatus makes it possible to steadily and safely supply pure ozone to an apparatus for oxidation treatment.
