Title: Mobile communication system, operation control method thereof and node to be used therefor
Inventor: KAWAGUCHI KENJI
IPC: H04L45/16
Filed: 2003-10-07
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate competition with another packet communication service when constructing a logic connection in an Iu interface required for providing a service corresponding to a high speed data communication called MBMS in a mobile communication system.  <P>SOLUTION: As a logic connection between an SGSN 12 of a CN 10 and a radio control device 22, a connection 121 for a PS (packet exchange processing) function for an existent packet communication service and a connection 122 for an MBMS service which is a novel high speed data communication are independently and separately arranged. Thus, there is no competition between different kinds of services such as a PS service and an MBMS service, and processing between the different kinds of services is performed without caring of mutual processes. Further, opening processing of a connection is singly performed for each service, so that complexity in processing of the SGSN 12 is eliminated.  <P>COPYRIGHT: (C)2004,JPO

IPC: F04B39/02
Filed: 2003-10-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a refrigerant compressor capable of using oil with low viscosity as refrigerator oil.  <P>SOLUTION: By approximately uniformly providing fine recesses 123 on a sliding face of a piston 115, a bore 113 or the like serving as sliding components of the refrigerant compressor, oil can be held on the sliding face, and clearance between the sliding parts is minutely changed at the time of sliding. This generates dynamic pressure between the sliding parts, and makes it easy to hold an oil film. Accordingly, since generation of abnormal wear can be prevented, oil with low viscosity of which oil film on the sliding face is easily broken can be used.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
