Title: Method of transmitting control signal between base station and gateway device in mobile communication system
Inventor: KATO YASUHIRO
IPC: H04L45/586
Filed: 2006-10-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of transmitting a control signal capable of setting SCTP connection and continuing to transmit and receive a control signal between a gateway device to which a mobile station is connected first and a base station stored in the other gateway device without setting and managing a relay protocol such as an SCCP, and a large number of IP addresses.  <P>SOLUTION: A handover original base station notifies the base station of a handover destination of the IP address of the gateway device under communication to which the mobile station is connected. A handover destination base station uses the notified IP address for establishing the SCTP connection with the gateway device under communication to which the mobile station is connected. The handover destination base station is achieved by transmitting and receiving the control signal to and from the gateway device under communication to which the mobile station is connected.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Title: METHOD FOR MANUFACTURING AlN-BASED GROUP III NITRIDE SINGLE CRYSTAL THICK FILM
Inventor: HIRAMATSU KAZUMASA
IPC: C30B25/10
Filed: 2006-11-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an AlN-based group III nitride single crystal thick film excellent in crystal quality and free from cracks.  <P>SOLUTION: When an AlN-based group III nitride thick film is obtained on an epitaxial substrate by an HVPE method, a first process for forming a thick film layer under a normal growth condition and a second process for mainly holding the thick film layer formed at the time at a high temperature T2 not lower than the thick film layer forming temperature T1 in the first process are repeatedly performed while being switched at an appropriate timing. Thereby, it is possible to form the thick film layer while successively reducing the strain existing in the thick film layer, formed in each first process, in each second process. Since the thick film layer in such a state that the tensile stress acting in an inplane direction is previously reduced after the thick film layer is formed can be formed, the generation of cracks in the thick film layer can be suppressed.  <P>COPYRIGHT: (C)2008,JPO&INPIT
