摘要:
An IP telephone apparatus is connected to an ENUM server and a Web server via an IP network. The ENUM server has a database that stores an IP telephone URI as terminal information of the IP telephone apparatus and a Web server URI corresponding to the IP telephone apparatus. The Web server stores image data captured by a camera. The IP telephone apparatus transmits to the ENUM server a query on terminal information of a destination IP telephone apparatus; receives from the ENUM server the terminal information of the destination IP telephone apparatus; acquires from the received terminal information a Web server URI corresponding to the destination IP telephone apparatus and performs visual communication with the Web server based on the Web server URI; and displays captured image data received from the Web server in the visual communication.

A source IP telephone inputs, from its numeric keypad, a telephone number of a call destination and obtains, from an ENUM server, a NAPTR record of the destination IP telephone based upon the input telephone number of the call destination. By referring to a search table, the source IP telephone retrieves, from the obtained NAPTR record, an available specific number in the ascending order of call rates from the lowest based upon communication services available to the source IP telephone. The source IP telephone transmits a call to the destination IP telephone by using the retrieved specific number.

A source IP telephone apparatus obtains, from an ENUM server, NAPTR records of a call destination based on a telephone number of the call destination, the telephone number being input by dialing. The source IP telephone apparatus then selects, from the obtained NAPTR records, a NAPTR record to be used for transmitting a call, based on a priority order, and transmits a call to the call destination based on an access method and a destination number included in the selected NAPTR record. When a destination IP telephone apparatus is busy, the second priority NAPTR record is selected and another call is made by automatically switching the access method.

When a call recipient name is clicked on a search result screen of a phonebook search system, an ENUM server is notified of an html file name which displays the call recipient profile, which is personal data. The ENUM server extracts a URI corresponding to an IP telephone service for the call recipient from a NAPTR record based on the html file name, and transmits the URI to a source IP telephone apparatus. The source IP telephone apparatus then becomes able to place a call to a destination IP telephone apparatus, using the URI corresponding to the IP telephone service for the call recipient.

An ENUM system includes a Web server and an ENUM server. The Web server stores first NAPTR records corresponding to an ENUM client and another ENUM client on an IP network. The ENUM server stores second NAPTR records in which first URIs are associated with predetermined information for being linked to the Web server. In the ENUM system, the ENUM client transmits, to the ENUM server, a query for the second NAPTR record of the another ENUM client. The ENUM client then transmits, to the Web server, a request for access to the first URI included in the received second NAPTR record, and obtains the first NAPTR record corresponding to the another ENUM client.

An expansion valve 1 comprises a piping member 10 equipped with passages to which refrigerant pipes are connected, and a cassette unit 100, the two members being formed as separate units. The cassette unit 100 comprises a tube member 110 having a flange portion 111, and at the interior of the tube member 110 are fixed a guide member 170, an orifice member 180, and a plate member 166. The pressure of the gas filled in a gas charge chamber 122 defined by a lid 120 and a diaphragm 130 displaces the diaphragm 130, the displacement being transmitted through a stopper member 140 to a shaft member 150. The shaft member 150 is guided by a guide member 170 and controls the valve means 160 inside a valve chamber 161. The cassette unit 100 is inserted to the piping member 10 and fixed to position by a ring 50. Seal members 62, 64, and 66 are equipped to appropriate areas between the cassette unit and the piping member.

An expansion valve 1 comprises a piping member 10 having passages to which pipes for a refrigerant are connected, and a cassette unit 100, which are formed as separate components. The cassette unit 100 comprises a tube member 110 accommodating a guide member 170, an orifice member 180 and a plate member 166. A diaphragm 130 sandwiched between a rising portion 121 of a lid 120 and an end 110′c of the tube member 110 and defining a gas charge chamber 122 is displaced, the movement of which is transmitted to a shaft member 150. The shaft member 150 is guided by a guide member 170 and drives a valve member 160 disposed within a valve chamber 161. The cassette unit 100 is inserted to the piping member 10 and fixed by a ring 50. Seal members 62, 64, 66 are disposed to necessary areas.
摘要:
A method of manufacturing methanol comprising producing a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, allowing reaction of the synthesis gas to take place over a catalyst to produce a crude methanol, separating the crude methanol into unreacted gas and liquid crude methanol, and distilling the liquid crude methanol to separate it into refined methanol and waste water. Carbon dioxide in combustion exhaust gas to be discharged from a reformer is recovered, and that in feeding the carbon dioxide to the upstream side and/or the downstream side of the reformer, part of the unreacted gas is utilized as a purge gas, a portion of which being utilized as a fuel for a combustion device of the reformer, while the balance of the purge gas being utilized as a fuel for other heating sources and/or as an agent for desulfurizating raw gas.

A thermal expansion valve 100 comprises a square column shaped valve body 110, and the valve body 110 contains a first passage 120 with a bottom to which the refrigerant is introduced, a valve chamber 122 formed near the bottom of the passage, a second refrigerant passage 126 traveling toward the evaporator, and a third refrigerant passage 128 returning from the evaporator. A valve means 130 equipped within the valve chamber is fixed to the working rod 132 and operated by a power element 160. The working rod 132 comprises a small-diameter portion 135, and the valve means 130 is fixed by a welding process W1 thereto with a valve seat 200 equipped in advance. The valve seat member 200 is press fit using the working rod 132 to a hole 116 formed to the valve body.
