Abstract: The container unit type cogeneration engine generator comprises a long generator container in which an engine and components on a generator main body side including a generator driven by the engine are accommodated, and a short exhaust heat utilizing container in which a boiler that generates steam and hot water for hot-water supply by utilizing exhaust heat of the engine and an exhaust heat utilizing apparatus including a heat exchanger are accommodated. A combination container unit is configured so that shorter walls on one end side of the both containers in a longer direction are positioned on a same straight line, and making both longer walls of the long generator container and the short exhaust heat utilizing container to face each other. Both containers are coupled with a plurality of pipes along the shorter direction of the containers across the facing walls along which the both containers are arranged.

Abstract: The container unit type cogeneration-using engine generator device is composed of a combination of a long generator container 20 in which an engine 21 and components on a generator main body side including a generator 22 driven by the engine are accommodated, and a short exhaust heat utilizing container in which a boiler 4 that generates steam and hot water for hot-water supply by utilizing exhaust heat of the engine and an exhaust heat utilizing apparatus including a heat exchanger 3 are accommodate. A combination container unit is configured by setting a reference surface A so that shorter walls on one end side of the both containers in a longer direction are respectively positioned on a same straight line, and making both longer walls of the long generator container and the short exhaust heat utilizing container to face each other and arranging the respective containers in parallel with longer direction across the facing walls 1b/20b by making the reference surface as a reference.

Abstract: The present invention obtains an engine generator device including: a longer generator container that houses a generator functional portion including an engine and a generator driven by the engine; and a shorter exhaust heat utilization container that houses a boiler utilizing the exhaust heat of the engine, and a heat exchanger. By effective utilization of the containers and by effective connection between the two containers, pipe and cable arrangement is not necessary. Further, by saving space, maintainability after the assembling is satisfactory.

Abstract: The present invention provides a novel separation reagent capable of obtaining a high extraction % of rhodium in a chlorine-based acid solution, which has never existed heretofore, and a method for separating and recovering a platinum group metal using the same. An organic phase composed of an amide-containing tertiary amine separation reagent represented by the structural formula shown below is brought into contact with an acid solution containing a platinum group metal, thereby extracting rhodium, platinum and palladium with the organic phase.

Abstract: A data transmitting and receiving system that can be easily built even in an environment where different models coexist, wherein the data transmitting module checks whether or not the OK file exists in the working area (S2), if the OK file exists (YES at S2), deletes the OK file (S4), and prevents data transmitting modules of other data transmitting apparatuses from accessing to the working area. The data transmitting module writes the FTP file in the working area (S6). After writing the FTP file, the data transmitting module creates an END file in the working area (S8) and declares that the data transmitting module completed writing the FTP file.
