Abstract: Encrypted music data and additional information necessary for accessing a server (30) are copied from a CD-ROM (200) onto a memory card (110). The memory card (110) receives via a digital portable phone network the distribution of a contents decoding key (Kc) necessary for decoding encrypted music data and control information data (AC1) for limiting the number of accesses to the memory card from the server (30).

Abstract: A method of cooling a steel pipe which can effectively suppress quenching-induced bending which occurs when quenching a thin-walled steel pipe with a wall thickness/outer diameter ratio of at most 0.07 without decreasing the manufacturing efficiency of the steel pipe comprises cooling the inner surface of the steel pipe by spraying cooling water into the interior of a horizontally-disposed steel pipe 2 while rotating the pipe in its circumferential direction, and the outer surface is cooled by producing a downward flow of cooling water streams 5a and 5b in a planar shape from above onto the outer surface along the axial direction of the steel pipe 2. Cooling of the inner surface is started at least 7 seconds before cooling of the outer surface.

Abstract: Conventionally, there is a description about stereophonically reproducing downloaded musical pieces or those stored on a memory card. A call speech is supported in monaural only. A realistic telephone call using stereo sound has been unavailable. The present invention aims at providing a cellular phone capable of a telephone call using stereo sound. The cellular phone terminal capable of speech communication with another information processing terminal. The cellular phone terminal is configured to comprise: a plurality of speakers for the speech communication; a receiver to receive a speech signal from a plurality of microphones of the other information processing terminal; and a processor to provide control so that the plurality of speakers can output the speech signal received by the receiver.

Abstract: For a group consisting of a plurality of users, data of users who constitute the group is acquired. Thereafter, the users are made to stay in a certain area by determining a user having high importance in the group based on the user data acquired and by providing adequate data to a user having high importance, and then data related to the group is provided. With the arrangement, for a case where a plurality of intended persons are to simultaneously receive data such as advertising and such intended persons form a group, it is possible to effectively notify data in an adequate method.

Abstract: A document referencing computer applying relationships or links between documents, wherein the documents are managed by a document managing computer, and the relationships or links are managed by a knowledge managing computer. The display of the links is controlled according to a variety of conditions. The display of a respective link between documents can be controlled by either a user who sets the respective link (the link setting user) or by a user using the document referencing computer to reference documents(a referencing user), thereby enabling related documents to be referenced easily.

Abstract: Multi-camera signal distribution conducted by a plurality of broadcasters has various problems of charging, video switching and copyright from the user's viewpoint. In order to solve these problems, first, a charging unit is provided for charging at a measured-rate charging to the assessment price of contents. Secondly, a program scramble is used to encrypt the whole service and a show scramble to encrypt each show, or each channel, thus making it possible to offer service according to the conditions of a contract the viewer made. Third, a show selection unit is provided to select shows on a show selection guide picture displayed on the screen of a communication terminal that has a remote control function. Use of this charging system could prevent the total amount of charging from increasing even if channels to view are frequently changed.

Abstract: The present intervention wherein a document referencing computer applies relationships between documents that are documents managed by a document managing computer, and a knowledge managing computer manages these relationship, or links. The display of the links is controlled according to a variety of conditions. The display of these links between documents can be controlled by either the user who set the link (the link setting user) or by a user using the system to reference documents, or a referencing user, thereby enabling related documents to be referenced easily.

Abstract: There is provided a thermal head having protective layers comprising a lower protective layer, an intermediate layer and a carbon-based protective layer which is composed of a plurality of sub-layers, wherein the carbon-based protective layer has stress values that become sequentially higher from one of the sub-layers located undermost toward another of the sub-layers located uppermost. The protective layers have significantly reduced corrosion and wear and is protected from cracking and peeling, whereupon the thermal head obtained can have sufficient durability and reliability to ensure that thermal recording of high-quality images is consistently performed over an extended period of operation.

Abstract: Compressed image data of a desired picture is read out from a memory having compressed image data of a sequential format stored therein and then subjected to an examination with respect to a plurality of frequency components of the read-out compressed image data. Part of the plurality of frequency components is deleted to obtain compressed image data of a quality lower than an original quality of the compressed image data. The obtained compressed image data of the lower quality is decoded and displayed on a display. The plurality of frequency components are deleted in a stepwise manner according to a traffic state of a transmission line through which the compressed image data is to be transmitted. For maintaining a picture frame rate to be constant, the plurality of frequency components may be deleted in a stepwise manner. For obtaining a desired decoding rate, the plurality of frequency components may be deleted in a stepwise manner.

Abstract: A mail reception/display control method which permits a user on a reception side to be informed the reception of an item of mail immediately upon reception of the mail even during the course of another job, and to ascertain the content of the received mail with ease upon mail reception. A mail reception detection unit included in each of the client terminals monitors the mail reception from any other client. When the mail reception has been detected, a mail attribute discrimination unit decides whether or not the received mail is to be transferred from a server to that particular client. When the mail transfer is required, a mail transfer unit transfers the mail from the server to the particular client. Subsequently, a mail reception display unit disposed at the client on the reception side presents a display to the effect that the mail has been received. Further, when the user has made a reply of confirmation to the display of the mail reception, a mail replay unit replays the received mail.
