Provided is an industrial gas turbine multi vane segment, which can be cast in one piece using a wax pattern method. The compositions are generated external to a point of use, at alkaline pH levels, viz. The print image encoded in the data unit is presented at a display device for monitoring or management before printout at the printing apparatus, the print image being presented at the display device by means of at least one of the color code and color values associated with the respective color separations such that the individual color separations are transparently superimposed. A mechanism for directing and interrupting power from the first and second power sources to the vacuum mechanism may also be included, such that the device may continuously receive power from at least one source. The second air guide is disposed on a back board, which is located on the rear side of the cushion member with a space.
