To reduce a weight of a valve main body of an expansion valve formed by an extrusion molding of a metal material such as an aluminum alloy or the like. A valve main body 100 is made of a material obtained by an extrusion molding of a metal material such as an aluminum alloy or the like. Two pair of holding faces 101a and 101b, and 102a and 102b are formed on both side face 100a and 100b in the extruding direction of the valve main body 100, and the other portions are to be concave as much as possible, so that the weight can be reduced. The holding faces 101a and 101b and the holding faces 102a and 102b are parallel faces, and come to be holding faces for chuck claws C1 and C2 at a time of machining.

An IFAX has a call controller that transmits and receives a SIP message to and from a destination apparatus via a SIP server, a file transmitter/receiver that transmits and receives image data to and from a Web server, and a communication manager that exchanges information for managing the image data transfer to and from the destination apparatus, by adding predetermined information to the SIP message. Thereby, the IFAX transfers the image data via the Web server while performing SIP-based communication with the destination apparatus.

An IP telephone system includes IP telephone apparatuses and an ENUM server. The IP telephone apparatuses, connected to an IP network, perform a voice communication. The ENUM server stores NAPTR resource records containing file transfer protocols supported by the IP telephone apparatuses and returns the NAPTR resource records, responding to a query of the IP telephone apparatuses. In the IP telephone system, when receiving a voice communication instruction from a user of a source IP telephone apparatus the source IP telephone apparatus inquires the ENUM server for NAPTR resource records of a destination IP telephone apparatus. When receiving a file transfer instruction during a voice communication, the source IP telephone apparatus transfers a file to the destination IP telephone apparatus, using a file transfer protocol specified in the NAPTR resource records.

Provided is a manufacturing method of an outer ring of a back-to-back arrangement double-row angular ball bearing from a raw material comprising an upsetting, a backward extrusion process, a punching, a rolling and a finishing, wherein an outer diameter of a first intermediate material produced by the upsetting is equal to or smaller than an inside diameter of an inner periphery large diameter portion of the inner circumference of a die used in the backward extrusion process and larger than an inside diameter of an inner periphery small portion of the die, and in a condition with the first intermediate material sitting on the inner periphery inclined portion of the die, the intermediate material is pushed toward a base of the die by a punch, to thereby the middle metal material with the highest cleanliness of the raw material is exposed to two outer ring raceways of the outer ring.

An IP telephone number query system includes a terminal, a Web server, and an ENUM server. The terminal displays a call recipient profile hypertext markup language (html) that is assigned a HTML document file name. The Web server includes a phonebook searcher that has a plurality of call recipient profile htmls, and returns a selected call recipient profile html in response to a request from the terminal. The ENUM server has a database, a query issuer and a reversed query issuer. The database stores a plurality of NAPTR resource records in association with an ENUM domain name, each NAPTR resource record containing a URI that at least includes a telephone number and a HTML document file name. The query issuer searches the database in response to a query by an ENUM domain name and returns a NAPTR resource record corresponding to the ENUM domain name. The reversed query issuer searches the database in response to a query by a URI of a HTML document file name and returns a URI of a telephone number corresponding to the ENUM domain name having the URI of the HTML document file name.
