Abstract: PURPOSE: A method for processing signaling between the next generation mobile communication network and a public switched telephone network/integrated services digital network is provided to interwork the next generation mobile communication network and the public switched telephone network/integrated services digital network. CONSTITUTION: If receiving an IAM(Initial Address Message)(101), a processor of a MSC(Mobile Switch Center) reads used channel information of the IAM and judges whether the corresponding channel is being used currently(102,103). If being used, the processor releases a call and terminates the process(104). If not being used, the processor performs a call process by using information within the IAM (105). The processor requests paging related to a destination subscriber to a RNC(Radio Network Controller) and transmits an ACM(Address Comolete Message) to a PSTN/ISDN(106). The RNC responses the paging request(107). The processor assigns switching system resources to an origination side(108). The processor notifies resource assignment condition to the RNC and the RNC responses to the notice(109). The processor registers the resource assignment condition in a cell coding/decoding part for enabling the cell coding/decoding part to code/decode an ATM cell. The RNC supplies a connection signal that a mobile station is hooked off. The processor transmits an ANM to the PSTN/ISDN for notifying the state that communication with a destination side station is possible. All signaling processes are terminated and call process is performed. If receiving a call release message, the processor performs a call release process.

Abstract: PURPOSE: A turbine blade is provided to cool a crossing part between an air foil rear circumference edge and a blade platform without increasing stress within the blade during operating an engine. CONSTITUTION: Cooling air supplied to a rim during operating an engine passes into a cooling passage(38) through a platform cooling supply channel(34) and is processed into a cooling hole(36) of a second surface(28). Then, the air flows onto the second surface and cools a film of a blade platform(24) nearing a rear circumference edge(22) of an air foil(14). The cooling hole is formed to make the speed of the cooling air slow so that mixing a fluid of operating the engine with the cooling air is minimized while cooling the film of the blade platform is maximized. Herein, the platform cooling supply channel does not decrease the entire weight of the blade and reduces the thermal slope of the blade platform by convectively cooling the blade platform.

Abstract: An injection tube for connecting a plenum to a combustion chamber includes a first mouth having a longitudinal axis and adapted for insertion into a cold plenum port or other component and a second mouth having a longitudinal axis and adapted for insertion into a hot chamber port or other component. To accommodate flexural, axial and torsional forces caused by differential thermal expansion between the two components, the mouths of the tube are configured to have multiple degrees of freedom within each corresponding port while maintaining port-mouth seal integrity. In an illustrative embodiment, the first mouth outer surfaces shape allows free slip of the first mouth parallel to the first mouth longitudinal axis, as well as rotation of the first mouth about both the first mouth longitudinal axis and a first mouth outer surface transverse axis. Mounted on the outer surface of the tube is a rocker arm adapted to engage a pivot mounted on the chamber outer surface or to engage the chamber outer surface itself. The rocker engagement allows rotation of the second mouth about a second mouth transverse axis while constraining axial movement of the tube, thereby preventing the second mouth from disengaging the chamber port.
