摘要:
A rotor is formed with a partition wall interposed between a first magnetic body and a second magnetic body. Projections of the partition wall block gaps between salient poles of the first magnetic body and salient poles of the second magnetic body which are arranged at shifted positions when seen in an axial direction of a rotating shaft to shield a flow of air flowing in the axial direction. Notches are formed in parts other than the gaps to decrease a volume thereof and to reduce inertia thereof.

Teeth-shaped portions 11b of a magnet 11 are formed in such a way that a part of the plane of projection of each of the teeth-shaped portions protrudes in a circumferential direction with respect to that of one of teeth 8b and 9b which is viewed from an axial direction of a first stator core 8 and a second stator core 9.

A motor rotor structure for an electric turbo charger is manufactured at low cost with good quality by fixedly fitting, over a shaft, a rotor core having electromagnetic steel sheets pre-formed as an integrated stack. The rotor structure includes a rotor core which is rotated by a magnetic field formed by a stator in a housing; a shaft configured to rotate a compressor impeller and the rotor core together; and a bearing supporting the shaft. The rotor includes the rotor core including the electromagnetic steel sheets; a stopper portion formed at an intermediate portion of the shaft to restrict axial movement of the rotor core; and a pressing unit which presses the rotor core fitted over the shaft against the stopper portion. The pressing unit prevents a circumferential phase shift between the shaft and the rotor core by a pressing force thereof.

A power element 22 is mounted on a board 21 outside an electric motor body 10 when viewed from an axial direction X. Heat produced by the power element 22 is conducted to a heat mass 32 formed outside the electric motor body 10 when similarly viewed from the axial direction X in a portion opposed to the power element 22, and radiated from a board-side heat radiating fin 33, and is also conducted through an uneven structure 42 which surrounds the power element 22 and radiated from a cover 40.

A solid-state imaging device includes a photoelectric conversion layer, a MOS transistor circuit. The photoelectric conversion layer is formed over a semiconductor substrate. The MOS transistor circuit reads out a signal corresponding to charges generated in the photoelectric conversion layer and then collected, and that is formed in the semiconductor substrate, the charges having a given polarity. The MOS transistor circuit includes a charge accumulation portion, a reset transistor, and an output transistor. The charge accumulation portion is electrically connected with the photoelectric conversion layer. The reset transistor resets a potential of the charge accumulation portion to a reset potential. The output transistor outputs a signal corresponding to the potential of the charge accumulation portion. The reset transistor and the output transistor have carriers whose polarity is opposite to the given polarity. In the MOS transistor circuit, following formula (1) is satisfied: GND
