    Abstract: A semiconductor commutator (Fig.4) which is constructed by providing a semiconductor region of a first conductivity type (3) and a semiconductor region of a second conductivity type, wherein there is provided a grain boundary (5) which is located near a junction surface (6) of the semiconductor region of the first conductivity type (3) and the semiconductor region of the second conductivity type so as not to cross said junction surface (6). The commutator may be manufactured by using a technique of selective nucleation and growth.

    Abstract: An MIS field effect transistor is provided with a first conduction type semiconductor layer having a channel portion, a second conduction type impurity region which forms opposite source and drain portion with the channel portion therebetween, and a gate electrode provided on the channel portion with a gate insulating film therebetween, wherein the channel and source portions respectively consist of semiconductors having different energy band gaps. The transistor enables holes to be smoothly moved between the source and channel portions, and has good saturation properties and a high source-drain endurance voltage.

    Abstract: The tiltable-body apparatus including a frame member, a tiltable body, and a pair of torsion springs having a twisting longitudinal axis. The torsion springs are disposed along the twisting longitudinal axis opposingly with the tiltable body being interposed, support the tiltable body flexibly and rotatably about the twisting longitudinal axis relative to the frame member, and include a plurality of planar portions, compliant directions of which intersect each other when viewed along a direction of the twisting longitudinal axis. A center of gravity of the tiltable body is positioned on the twisting longitudinal axis of the torsion springs.
