  • Publication number: 20100143239
    Abstract: The method for parallel operation of moisture generating reactors according to the present invention operates so that an orifice, provided with an orifice hole having a predetermined opening diameter, is disposed on a mixed-gas inlet side of each of a plurality of moisture generating reactors connected in parallel with each other, and mixed gas G consisting of hydrogen and oxygen is supplied from a mixer to each of the moisture generating reactors through each orifice, and the flows of moisture generated by the moisture generating reactors are combined, and the resulting combined moisture is supplied to an apparatus that uses high-purity water. Thus, a need to increase the amount of high-purity water supply is met by allowing a plurality of moisture generating reactors to perform a parallel water generating operation by branching off a mixed gas consisting of H2 and O2 by using a simple orifice construction.

  • Patent number: 7553459
    Abstract: 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.

  • Patent number: 7502452
    Abstract: A contents reproducing apparatus includes a main CPU, and the main CPU causes a DSP to decode broadcast data included in a radio packet signal input via a LAN controller in a radio mode, and inputs decoded PCM data to a D/A converter. As a result, a sound of Internet radio is output from a speaker. On the other hand, in a telephone mode, the main CPU causes the DSP to decode receiving speech data included in a telephone packet signal input via the LAN controller, and inputs decoded PCM data to a PCM codec. The CPU causes the DSP to encode the sending speech data input from the PCM codec, and packetizes encoded data to input it to the LAN controller. Thus, it is possible to make a communication with an opponent party.

  • Publication number: 20080126646
    Abstract: When accepting a send request for requesting to send a command to a client from a terminal (mobile phone, PC), a server determines terminal types. When the determination result shows a PC, a command is sent to the client, and an execution result of the sent command is received from the client, and the received execution result is sent to the PC. When the determination result shows a mobile phone, the client is instructed to issue a port releasing request to request a router to release an arbitrary port, a number of the released port is acquired from the client, and the mobile phone is instructed to send the command to the destination specified by the destination information including the acquired port number.

  • Publication number: 20080034123
    Abstract: A communication terminal includes a CPU (28). The CPU (28) issues to a router (16) a send request for requesting the router (16) to send an ask signal for repetitive responses to a server (14). Then, the ask signal is sent to the server (14) by the router (16), and a receive port is temporarily opened. From the server (14), 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 (16), but a response signal sent back after the receive port is closed is discarded in the router (16). The CPU (28) repeatedly issues a send request to the router (16) regarding a time indicated by time information attached to the response signal lastly received as an issuance cycle (T).

  • Publication number: 20070271329
    Abstract: A command processing apparatus includes a CPU (28). The CPU (28) determines whether or not a router (16) is compliant with UPnP, and issues a port releasing request to the router (16) 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 (14). The destination information is sent to the server (14) by the router (16), and the server (14) 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 (14) by the router (16), and the response wait port is temporarily released. The server (14) outputs a command to the response wait port on the basis of the identifier included in the destination information.
