Title: Cavitation prevention structure for centrifugal compressor
Inventor: CHOI MIN HWAN
IPC: F04C29/06
Filed: 2007-02-02
Abstract: A cavitation prevention structure for a centrifugal compressor is provided to prevent damage to an oil pump by canceling the flow of refrigerant gas with the spraying pressure. A cavitation prevention structure for a centrifugal compressor(10) comprises a transmission part(14), an oil pump(24), and a pipe(30). The transmission part includes a driving gear(16), which is engaged with a driven gear(18), inside a housing in order to raise refrigerant gas into high pressure. The oil pump is installed at the lower part of the transmission part to be submerged in working fluid. The pipe sprays portions of the refrigerant gas and the working fluid compressed from a compressor to the transmission part. The cavitation is prevented by canceling the flow of the refrigerant gas due to the rotation of the transmission part with the spraying pressure from a spray hole(32).

Title: Method for diagnosising traffic path in mobile communication system and the system
Inventor: JI CHANG YONG
IPC: H04L12/24
Filed: 2007-02-12
Abstract: A traffic path diagnostic system in a mobile communication system and a method thereof are provided to shorten the time for diagnosing a traffic path by segmenting the traffic path according to AALs(ATM Adaptation Layers) and sequentially diagnosing each of the segmented paths with an AAL(ATM Adaptation Layer) 0 cell. A traffic path diagnostic system, if a diagnosis request message is received from a URM(Universal Mobile Telecommunication System Radio Access Network Manager), sets up a traffic path(201). If response messages for traffic path setup are received from an RNC(Radio Network Controller) and a BTS(Base station Transceiver System), a GAN(General ATM Network) in the traffic path diagnostic system judges that traffic path setup has been completed(203). The traffic path diagnostic system executes diagnostic setup and diagnosis for the first path, or a traffic path in the RNC(205). If a response message for the diagnostic setup and diagnostic execution of the first path is received, the traffic path diagnostic system judges that the diagnostic setup and diagnostic execution of the first path have been completed(207). The traffic path diagnostic system executes diagnostic setup and diagnosis for the second path, or a traffic path between the RNC and the BTS(209). If a response message for the diagnostic setup and diagnostic execution of the second path is received, the traffic path diagnostic system judges that the diagnostic setup and diagnostic execution of the second path have been completed(211). The traffic path diagnostic system executes diagnostic setup and diagnosis for the third path, or a traffic path in the BTS(213). If a response message for the diagnostic setup and diagnostic execution of the third path is received, the traffic path diagnostic system judges that the diagnostic setup and diagnostic execution of the first path have been completed(215). Then the traffic path diagnostic system transmits traffic path diagnostic results to the URM(217).
