Abstract: A method for producing a low-molecular fluorine compound, including a decomposition step for heating a microwave absorber by the irradiation with microwaves in a reaction vessel provided with a carrier gas inlet and a decomposed gas outlet and then bringing the heated microwave absorber into contact with particles of a material containing a fluororesin to decompose the fluororesin into the low-molecular fluorine compound, wherein the carrier gas temperature TI (° C.) at the inlet is set to a temperature lower than the temperature TR (° C.) of the heated microwave absorber. Accordingly, a temperature difference can be provided such that the temperature of a produced gas discharged from the reaction vessel becomes lower than the temperature in the decomposition reaction system, i.e., the temperature of the heated microwave absorber.

Abstract: An information provision control system is provided whereby preferential information can be provided only to the employees of an affiliated enterprise, using an Internet home page. An authentication server stores the domain names of terminals of affiliated parties who are permitted to obtain information stored in a contents server. Moreover, the authentication server, when the contents server is accessed, compares the domain name of the accessed terminal with stored domain names of terminals of affiliated parties, and judges if the terminal is the terminal of an affiliated party. A member management server, in the case where the terminal is the terminal of the affiliated party, limits the range of information to be provided according to the affiliated party.
