A gas-insulated electrical device includes a covering film covering an inner surface of a ground tank filled with an insulation gas. The covering film is formed of an insulation dielectric covering film that becomes more positively charged than metals in a triboelectric series, and becomes positively charged upon contact with metal foreign matter. At the same time, the metal foreign matter becomes negatively charged upon contact with the covering film. In a case where the high-voltage conductor is charged to a negative polarity, a Coulomb's force acts on the metal foreign matter in contact with the covering film in a direction away from the high-voltage conductor. The metal foreign matter in the ground tank is thus suppressed from floating.

Object To provide a technique for authenticating a communication partner using an electronic certificate containing personal information. Solving Means When a client apparatus receives a request for an electronic certificate from a server apparatus, the server apparatus reads a client certificate containing personal information and a server public key of the server apparatus from a storage unit and encrypts the client certificate using the server public key. The client apparatus also creates a temporary electronic certificate by setting, in a basic field of an electronic certificate, a predetermined item indicating that the electronic certificate is a temporary electronic certificate and by setting the client certificate having been encrypted in an extension field of the electronic certificate. Then, the client apparatus sends the temporary electronic certificate to the server apparatus.

Systems and methods are provided that record an easily viewable log of operations. A particular system includes a response receiving unit that receives an input response from a server, the input response related to a first client request and including first content adapted to prompt data input via a client. Additionally, the system includes a response sending unit that sends the client an output response, including the first content and an identifier to identify the first content and a logging database to record the first content in association with the identifier. Further, the system includes a request receiving unit that receives a second client request including input data related to the first content and the identifier and a content combining unit that combines the input data extracted from the second client request with the first content that is retrieved from the logging database based on the identifier.

Recording a log of operations

When electric discharging occurs inside a gas insulated apparatus in which sulfur hexafluoride is filled, hydrogen-fluoride gas is generated, which abrades a part formed of glass fiber reinforced plastics included in the apparatus. Previously, resin for preventing the abrasion has been coated on the surface of the part; however, a problem has occurred that the coating film peels off. Organic fiber woven cloth woven using organic fiber such as aramid fiber or the like having hydrogen fluoride resistance and mechanical toughness is wrapped around the surface of glass fiber reinforced plastics, and thermosetting resin is wettably impregnated into weave patterns of the organic fiber woven cloth and then heat cured; thereby, an abrasion-preventing protection layer that does not peel off is formed.

A session management server, which is provided with a service determination table having a plurality of entries each indicating a service identifier in association with possible particular items of information which may be extracted from a session setup request packet, receives a session setup request packet issued from a client to a particular application server and determines whether the client terminal is authorized to receive an information service by referring to the determination table, in place of the particular application server. When the determination results in success, the session setup request packet is forwarded to the particular application server.

Disclosed here is a method for sending/receiving a message through a session control server disposed in each of hierarchical layers of a network system having a hierarchical structure. To achieve the above object, each of the session control servers is provided with operation mode confirming means for confirming a set operation mode and fixed destination solution means for setting an address so as to relay each received message to a specific address in accordance with the set operation mode. The session control server is also provided with location solution means for registering/managing a public address to be opened to external by a user and a user address given in the sub-domain to which the user belongs actually. Because a parent domain address can be used as an address to be opened to external for operating the session control server, the problems to occur due to a change of the user belonging sub-domain can be hidden from external and the parent domain can manage message traffics collectively.

Session control system for hierarchical relaying processes

Origination and incoming are regulated for each service in user units. An origination filter table stores contract service information indicating whether or not each service can be used and the maximum number of sessions that can be activated by the originator corresponding to each originator identifier (for example, SIP-URI). An incoming filter table stores incoming enable/refusal information and an originator identifier from which incoming is enabled or refused corresponding to each receiver identifier. A communication control section references the contract service information and the maximum number of sessions in the origination filter table based on the originator identifier in the message received from a communication terminal, determines whether or not the service indicated by service type information in the message can be used, and determines whether or not a new session can be established. The communication control section references the incoming enable/refusal information in the incoming filter table based on the receipt party and originator identifiers in the message and determines whether or not incoming is enabled.
