A stator for use in a rotating electrical machine is constituted by arranging the prescribed number of stator units in the circumferential direction of a stator core having a circular ring shape. The compounds and compositions of the invention can induce the biosynthesis of various cytokines and are useful in the treatment of a variety of conditions including viral diseases and neoplastic diseases. When the outer covering 6 is attached to the main body 2 in a state in which the operation panel unit 16 is attached to the main body 2, sliding of the operation panel unit 16 is restricted. In measurement thereof with a contact type sensor, a problem that pollutants elute out is caused. The base is accommodated in the adjustment slot. The receiving portion serves to receive at least one receiving means, which serves in turn to receive or collect at least one biological specimen obtained by laser microdissection from biological material located in the container.
