Abstract: An electronic settlement system includes a data storage device such as an IC card in which value information is stored, a client device provided with an information input/output function to the data storage device, a settlement management device for managing settlement between the data storage device and a store device, and a communication system for connecting the client device, and the settlement management device so as to enable bidirectional communication. The settlement management device creates settlement information for making settlement by the data storage device, subjects the settlement information to an encryption processing by using a common key shared by the settlement management device and the data storage device, and transmits the settlement information subjected to the encryption processing to the client device, and the client device outputs the settlement information received from the settlement management device to the data storage device.

Abstract: A communication between a terminal connected to the Internet, like a household terminal, and a server can be performed by simple processing at any time after security is ensured. In a case where control of a particular terminal connected to a predetermined network is performed from the server, when there is a predetermined processing request at the particular terminal from the server or an external terminal connected to the server, a callback request is sent to the server or the particular terminal. At the particular terminal receiving the callback request, a callback request response is made to the server by a predetermined communication method in which security is ensured, and instructions for performing predetermined processing by the predetermined communication method are sent, as a response from the server with respect to the callback request response, to the particular terminal.

Abstract: A magnetic tape which is run at a speed of 4 m/sec. or higher and has recording tracks with a width of 21 ?m or less, and which includes a non-magnetic support, at least one magnetic layer formed on one surface of the non-magnetic support, and a backcoat layer formed on the other surface of the non-magnetic support, wherein servo signals for controlling tracking are recorded on the magnetic layer or the backcoat layer, the value of (?/W)×(V/f) is 10 [s?1] or less, and/or the value of (?/W) is 0.1 or less, wherein V [mm/sec.] is a tape-running speed is; ? [?m] is an amount of a weave with a cycle of f [mm] on one edge of the tape or the other edge thereof as the reference side for the running of the tape; and W [?m] is a width of the recording track. The magnetic tape can decrease PES and off-track and thus is excellent in servo tracking performance.

Abstract: Disclosed herein is an authentication system offering high degrees of security and convenience by use of two storage media. An automatic log-in system (100) requests a server (110) to perform a user authentication process using card-specific information (101) retrieved from an IC card (10) and password information (102) from a portable memory (11). The server (110) authenticates the user by acquiring a user ID and a password using the card-specific information (101) and password information (102). The card-specific information (101) and password information (102) constitute authentication request information, and the user ID and password make up authentication information. Following successful authentication of the user, the server (110) allows the user to log in; in case of unsuccessful authentication, the server (110) denies log-in.

Abstract: An effective electronic settlement system in which the number of checks is small. The electronic settlement system includes a data storage device such as an IC card in which value information is stored, a client device provided with an information input/output function to the data storage device, a store device for providing commodities or services, a settlement management device for managing settlement between the data storage device and the store device, and a communication system for connecting the client device, the store device, and the settlement management device so as to enable bidirectional communication.

Abstract: A support shaft has an integral protrusion which is abuttingly engageable with an arcuate portion of a support panel for limiting rotation of the support panel relative to the support shaft. A protrusion is provided at each axial end of the support shaft, while an opening with a slit-like opening portion is provided on each side panel of a seat back frame. The protrusion at each axial end of the support shaft and the opening at each side panel are constructed and arranged so that each axial end is capable of passing through the opening only when the support shaft is held in a particular position. The support shaft is put out of the particular position when in use such that each axial end is prevented from slipping out of the opening.
