A rotating blade for a gas turbine engine is provided which is configured to uniformly diffuse cooling air from an internal cavity about the tip of the rotating blade. The system includes a memory for storing a data file and an automatic transmission control file for briefly describing information of a file name of the file to be transmitted and a destination address, and a communication unit for transmitting the data file according to the automatic transmission control file. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. The insecticide andor fungicide is also dispersed throughout the lignocellulosic particles.
