Method for parallel operation of reactors that generate moisture

A communication terminal includes a CPU (). The CPU () issues to a router () a send request for requesting the router () to send an ask signal for repetitive responses to a server (). Then, the ask signal is sent to the server () by the router (), and a receive port is temporarily opened. From the server (), a response signal is repeatedly sent in response to the ask signal. To the response signal, time information representative of a waiting time from receiving an ask signal to its reply is attached. A response signal sent back while the receive port is opened arrives at the communication terminal through the router (), but a response signal sent back after the receive port is closed is discarded in the router (). The CPU () repeatedly issues a send request to the router () regarding a time indicated by time information attached to the response signal lastly received as an issuance cycle (T).

Communications terminal with optimum send interval

A command processing apparatus includes a CPU (). The CPU () determines whether or not a router () is compliant with UPnP, and issues a port releasing request to the router () when the determination result is affirmative. Thus, a specific port is released. Next, destination information including an identifier of the specific port is requested to be sent to a server (). The destination information is sent to the server () by the router (), and the server () sends a command to the specific port on the basis of the identifier included in the destination information. When the determination result is negative, an information send request is repeatedly issued. Every issuance, destination information including an identifier of an arbitrary port (response wait port) is sent to the server () by the router (), and the response wait port is temporarily released. The server () outputs a command to the response wait port on the basis of the identifier included in the destination information.

A safe, reduced pressure apparatus for generating water vapor from hydrogen and oxygen and feeding high purity moisture to processes such as semiconductor production. The apparatus eliminates the possibility of the gas igniting by maintaining the internal pressure of the catalytic reactor for generating moisture at a high level while supplying moisture gas from the reactor under reduced pressure. A heat dissipation reactor improvement substantially increases moisture generation without being an enlargement in size by efficient cooling of the reactor alumite-treated fins.
