Abstract: A working machine includes: a counterweight having a weight outer surface having such a shape as to cover at least a part of left and right portions of the machine chamber and cover a rear portion thereof, a weight inner surface, and a weight top surface; and an antenna support member having an antenna attachment part and a plurality of legs. The counterweight has a weight recess part recessed from the weight outer surface toward the weight inner surface at an upper end of the weight outer surface. The legs include a first leg having a first fixed part fixed to the weight recess part, and a second leg having a second fixed part fixed to the weight recess part or the weight top surface.

Abstract: A process for producing a thermoelectric material comprising mixing at least two of bismuth, tellurium, selenium, and antimony and, if desired, a dopant, melting the mixture, grinding the resulting alloy ingot, forming the powder, and sintering the green body under normal pressure, or hot pressing the powder, wherein the grinding and the normal sintering or hot pressing are carried out in the presence of a solvent represented by CnH2n+1OH or CnH2n+2CO (wherein n is 1, 2 or 3).
