This process to oxidize the second oxidizing film 104 on the nitriding film 103 in the atmosphere which does not contain vapor can prevent the production of nitride induced by the generation of ammonia at a pin hole section 106 and can grow a thin and excellent oxidizing film without oxidizing a second oxidizing film 102 thickly and locally. It is, therefore, possible to prevent deterioration of the dielectric strength of an insulation film which comprises the nitriding film 103 and the oxidizing film 104.

Title: Absorption type cooling system
Inventor: YAMADA YASUO
IPC: F25B27/02
Filed: 1992-08-13
Abstract: PURPOSE:To improve the coefficient of performance by a method wherein changeover periods of absorption process and regeneration process are extended when the heating value of a heater is small, and shortened when the heating value is large. CONSTITUTION:The temperature in an exhaust gas introducing path 25 is detected by a temperature sensor 51, and the magnitude of heating value obtained through regeneration process in a second absorber 21 is estimated based on the detected temperature. When the heating value is small, changeover periods of absorption process in a first absorber 20 and regeneration process in the second absorber 21 are extended, and when the heating value is large, the changeover periods of the processes are shortened, Therefore, when the heating value of the exhaust gas supplied to the exhaust gas introducing path 25 is small, a sufficient period of time required for regenerating absorption medium is maintained, and when the heating value of the exhaust gas is large, the period of time required for regenerating the refrigerant is not spent excessively, resulting in an improvement of the overall cooling ability. Thereby, the coefficient of performance can be certainly improved even when a heater which fluctuates in heating value is used.
