Abstract: A system for disposing of wastes, in accordance with the present invention includes a plurality of terminal devices located at sites in which steps in a waste-recycling process are carried out, a network, and a host server making communication with the terminal devices through the network. Each of the terminal devices transmits data indicative of a condition of waste in each of the steps, to the host server, and the host server compares the data in each of the steps to one another to judge whether the condition of waste changes in each of the steps.

Abstract: An electric system has exothermic components housed in a case; the case is formed with ventilation holes, and a fan forcibly evacuates the hot air from the inner space through the ventilation holes for removing heat from the exothermic components; foamable pain is spread on the surface near the ventilation hole, and a fuse element is exposed to the air passage; when a fire breaks out inside the case, the paint foams for closing the ventilation hole, and the fuse element stops the fans, whereby the fire is extinguished without being spread to the outside the case.
