In a hybrid type compressor, a one-way clutch is provided between a magnet rotor and a rotor shaft for allowing rotational driving force generated by an electric motor unit to be transmitted only from a rotor to a shaft. Thus, the rotational driving force generated by a vehicle engine is not transmitted from the rotor shaft to the magnet rotor. That is, an inertia moment of a rotational system with respect to a vehicle engine is made small, thereby reducing the impact vibration when the clutch mechanism engages.

A musical performance processing apparatus that provides better assistance for student's practice. The apparatus includes a main unit in which music data including performance information of right- and left hand parts is stored, and a performance terminal having a keyboard divided into two key ranges by a split point. Each key range is set as a tapping or normal performance key range. The main unit generates a musical tone when input with performance information generated by depression of a key in the normal performance key range, and automatically reproduces performance information of designated part of music data for the number of beats corresponding to key depression, when input with performance information generated by depression of a key in the tapping performance key range. Sounding is stopped, if there is a deviation between a tempo of teacher's tapping performance and timing of student's performance.

In a bottom-gate-type thin film transistor used in a liquid crystal display device in which a poly-Si layer and an a-Si layer are stacked, a quantity of an ON current which flows in the thin film transistor can be increased. A poly-Si layer and an a-Si layer are stacked on a gate electrode as an active layer by way of a gate insulation film therebetween in order of the poly-Si layer and the a-Si layer. An n+Si layer and a source/drain layer are formed on the a-Si layer thus forming a thin film transistor. A forward current which flows in the thin film transistor mainly flows in the poly-Si layer. To decrease contact resistance against the forward current between the poly-Si layer and the n+Si layer, an edge portion of the a-Si layer and an edge portion of the poly-Si layer assume a concavo-convex shape thus particularly increasing a contact area between the poly-Si layer and the n+Si layer whereby the contact resistance against the forward current can be decreased leading to the increase of a quantity of an ON current.
