An extrusion die has back holes for introducing a raw material to be molded and slits for extruding the raw material and is used for extrusion molding of a honeycomb structure. A tensile stress generating film, such as a silicon nitride, is formed on the at least one NFET by blanket deposition and patterning. At least one mechanical property of the subject is determined based at least in part on a distance between wavefronts of the first and second shear waves. The game enables the player to keep the offer or change either the value or the multiplier.
