Abstract: PURPOSE: A gas turbine blade with flatform undercut is provided to reduce thermal stress and mechanical stress on a rear end of an airfoil root and to expand the span of fatigue. CONSTITUTION: A gas turbine blade(30) with flatform undercut is composed of a platform(38) being undercut with a groove(46). The groove extends from a concave side(50) to a trailing edge side(48) of the platform, where the groove exits the platform. The groove has a depth entering a stress line causing a change to a load path direction away from the trailing edge. The location and depth of the groove reduces both high thermal stress and mechanical stress arising at a connection portion of a blade trailing edge and the platform of the gas turbine air cooled moving blade during a steady state, full speed, full load conditions as well as transient engine operations.

Title: Method of Managing PLD on the Web
Inventor: HAN JEONG NAM
IPC: H04L12/24
Filed: 2001-12-26
Abstract: PURPOSE: A method for managing PLD(Program Loading Data) on the Web is provided to quickly search problems caused by PLD including information of the inside of an exchange and subscriber information in a Web site. CONSTITUTION: An operator terminal requests PLD change to an exchange(S41). If the exchange transmits a result of the request to the operator terminal, the operator terminal stores details of the PLD change in a hard disk(S42). Whether transmitted data are normally processed is decided(S43). If not, the data are discarded(S44), and if successfully processed, the data are temporarily buffered in a PC(Personal Computer) of the operator terminal(S45). If the buffered data reaches a designated buffer size, the data are stored in a disk(S46). If the buffered data exceeds the buffer size, whether an Internet network is normal is decided(S48), if not, to store corresponding buffering data in a temporary storage of the operator terminal, and if normal, to transmit the buffering data to a Web server(S50) and newly produce PLD(S51). The Web server decides whether update is normally performed(S52), if so, to store the newly produced PLD in a data storage(S53). When transmitting the PLD through the Internet network, the PLD are compressed(S54) and delivered to an operating station site through the Internet network(S55). The operator terminal receives the PLD, if the exchange is in a time with the least calls, to apply the PLD to the exchange(S56,S57).
