Abstract: The present invention relates to a common key sharing method in an ad hoc network constituted by wireless communication terminals implemented with relay functions thereon, comprising a common key generating step in which a first wireless communication terminal responsible for relaying generates a common key, a common key distributing step in which the first wireless communication terminal responsible for relaying distributes the common key to a second wireless communication terminal within a wireless communication area, and a transferring step in which the second wireless communication terminal which received the common key holds the common key, and the second wireless communication terminal transfers the common key to a third wireless communication terminal within a wireless communication area, when the second wireless communication terminal is responsible for relaying. Accordingly, it is possible to share a common encryption key within the ad hoc network.

Abstract: One objective of the present invention is to determine a location for a relay terminal in a radio network, without preparatory surveying a radio status, and to arrange the relay terminal at the location. Another objective is to provide a method for retrieving the arranged relay terminal. When a relay terminal is to be arranged, the relay terminal transmits a survey packet to examine the quality of communication with a communication terminal or other relay terminal. Wherer a location is appropriate, the relay terminal gives a notice. The arranged terminal relays communication. Further, when the relay terminal is to be retrieved, the relay terminal carried by a user transmits a retrieval packet to the arranged relay terminal, which notifies the user of its presence by light, sounds, or returning a packet. In this manner, a single relay terminal provides functions of arrangement, relay and retrieval.

Abstract: A plurality of packet gate ways (PGWS) are connected between a mobile communication system and an internet so that the corresponding IP subnetworks to those PGWs may be built. A visitor location register (VLR) operates to notify the PGW of location information of the mobile station (MS) and an IP address of a data terminal connected with the MS. If the notified IP address belongs to another IP subnetwork, the PGW notifies the corresponding PGW to that IP subnetwork of a fact that the local PGW is a destination. The PGW operates to manage the location information of the MS connected with the data terminal based on the notified content and perform the packet routing based on the managed content.

Abstract: When a sender sends a transmission message to a receiver by use of a communication appliance such as telephone, portable telephone, facsimile or electronic mail, the transmission massage is temporarily received by a computer-telephony integration (CTI) server. The CTI server makes reference to a user contact table to thereby specify a contact point of the receiver at present and the kind of a communication appliance capable of being used by the receiver which are registered in advance in the user contact table. Then, the CTI server sends the transmission message to the receiver after automatic media conversion in accordance with the communication appliance and reception condition which are allowed for the receiver to use. A reception condition requested by the sender may be reflected in a part of the reception condition of the receiver.

Abstract: Resins used in radiation detectors undergo quality change owing to the irradiation. The quality change includes the degradation in the light reflectivity and light transmittance of the resins. The quality change of the resin is one of the causes for the output current reduction of the detectors and affects operating life of the detector. A radiation detector and a CT device are provided which are small in the output current degradation of the radiation detector and long in working life even with a large irradiation. A cured mixture of a rutile type titanium oxide powder and a polyester resin is used for the light reflecting material covering the scintillators. Additionally, a polyester resin is used for bonding the scintillators and semiconductor photodetecting elements together.
