摘要:
A method for forming dense ceramics, particularly a ceramic coating by a low temperature treatment is provided. The method for forming ceramics according to the invention is characterized in that a polysilazane having a number-average molecular weight of 100 to 50,000 or a modified polysilazane thereof is subjected to a heat treatment, then exposed to an atmosphere containing water vapor or immersed in distilled water containing a catalyst, or both, or is brought into contact with Pd.sup.2+ ions and water, the polysilazane having a skeleton comprising the unit represented by the following general formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each independently represents a hydrogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an aryl group, a group other than the above and having a carbon atom directly attached to the silicon atom, an alkylsilyl group, an alkylamino group and an alkoxy group; with the proviso that at least one of R.sub.1, R.sup.2 and R.sup.3 is a hydrogen atom. A method wherein said modified polysilazane is only fired at a temperature of 400.degree. C. or below is also provided.

A node device communicates with a plurality of node devices via a network. The node device includes a first obtaining unit that obtains search information for searching the content data stored in at least one node device, and a particular determination unit that applies a predetermined rule to determine whether the search information is required to be stored. A first storage unit stores the search information when required. A second obtaining unit obtains the content data from the information communication system, and a second storage unit stores the content data from the second obtaining unit. A third storage unit stores the search information corresponding to the stored content data in the second storage unit. A management unit manages the stored content in the second storage unit based on the search information stored in at least one of the first storage unit and the third storage unit.
摘要:
An information communication system formed by plural nodes, mutually connected through a communication route, the nodes including: a memory means for memorizing node information indicating a candidate node of information transfer destination; a participation request information transfer means for judging whether node information indicating a node of a transfer destination in response to information of the participation request node is memorized, when participation request information is received, and for transferring the participation request information to the node when the node information is memorized; an existence confirmation information sending means for judging whether information of other than the transfer destination is memorized when the participation request information is received, and for sending existence confirmation information to the node when the information other than the transfer destination is memorized; and a means for sending return information to the participation request node device when the existence confirmation information is received.

To prevent a preview of contents by a person who does not have a right to view or listen, by distributing encoded contents data which are difficult for a third person to decode. A new participation terminal apparatus, as well as transmitting a participation request to a parent terminal apparatus of a connection destination candidate, transmits a participation disclosure key for encoding a contents decoding key. The parent terminal of the connection destination candidate which receives the participation disclosure key from the new participation terminal apparatus generates an encoded decoding key, which is a contents decoding key encoded using the participation disclosure key received, and transmits it to the new participation terminal apparatus. The new participation terminal apparatus decodes the encoded decoding key received, using a participation secret key stored in a participation key storage section, acquiring a contents decoding key. Using the contents decoding key, the new participation terminal apparatus decodes distributed encoded contents data, and carries out a reproduction process.
摘要:
In a request node for receiving content with a preset distribution completion time limit, which is distributed from a content node connected to the request node via a network, remaining time to the distribution completion time limit is detected. On the basis of the detected remaining time, a download speed necessary for distributing the content in the whole of the detected remaining time and completing the distribution within the remaining time is determined. Content request information including information indicative of the determined download speed is transmitted to the request node.
摘要:
A node device included in a distributed content storing system which includes a plurality of node devices mutually communicable through a network, the node device including: a means for receiving storing request information indicative of storing request of the content data; a means for judging whether or not a standard for determining a degree of load of the network in response to the storing request information; and a means for acquiring and storing content data related to the storing request information from another node device storing the content data through the network in a case where the standard is satisfied.
