摘要:
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.

This invention provided a manufacturing method to process a small-diameter step section 18 on an inside end section of a hub body 13a that comprises an outward facing flange 15 and a positioning cylinder 16 stably and with high precision. In this invention, an intermediate material 40 is pressed between a lower punch 36 and an upper punch 46 with an outer peripheral surface of the intermediate material 40 being held by a lower die 37 and an upper die 43, and then a part of the intermediate material 40 is pressed into the lower punch 36 such that the small-diameter step section 18 is formed by cold plastic working.

An Internet telephone system that stores NAPTR resource records which include URIs corresponding to the phone numbers of individual terminals (Internet telephones), as well as IP addresses that correspond to those URIs. The system uses a server that stores a plurality of URIs corresponding to telephone numbers of terminals adjacent to a particular telephone, and uses a terminal that receives, from the sever, URI(s) and other information corresponding to an input telephone number, and places calls to destinations. In the Internet telephone system according to the present invention, the sever returns a plurality of URIs in response to requests, from the terminal, for URIs corresponding to a particular telephone number, and the terminal places a call to a destination corresponding to one of these URIs. When no connection is possible with the destination, a different URI is selected, and another call is placed to a destination corresponding to the different URI.

The lower part of a material to be molded forms a lower, seal with a die. A punch applying a molding force to the material forms an upper seal with the perimeter of the die. The space between the upper and lower, seals forms a pressure chamber that is filled with a fluid. As the punch descends into the die, the fluid is pressurized. The lower seal is a complete seal to prevent leakage of fluid into the die. The upper seal is given a clearance with the die that permits controlled leakage of fluid therepast at a rate that limits the maximum pressure in the pressure chamber while permitting the development of an adequate pressure on the material being molded.

In a process for producing an aromatic carboxylic acid, it is a dehydrating process which can achieve compactification of a step for removing water from a mixture of acetic acid and water produced in the production process, and which can reduce the consumed energy. In a production process of an aromatic carboxylic acid having an oxidation reaction step for producing a slurry of an aromatic carboxylic acid by carrying out liquid-phase oxidation reaction of an alkyl aromatic compound with an oxygen-containing gas in a solvent containing acetic acid in the presence of an oxidation catalyst, at least a portion of a mixture containing acetic acid and water produced in the production steps is separated into a permeable gas mainly comprising water and nonpermeable substances mainly comprising acetic acid, using a separation membrane having water selectivity.

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 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.
摘要:
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.
