Abstract: A refrigeration apparatus 10 according to one embodiment opens a liquid bypass control valve 16B when a discharge temperature of the refrigerant, which has been discharged from a compressor 11 and does not yet flow into a condenser 12, exceeds a threshold value, and closes the liquid bypass control valve 16B when the discharge temperature is equal to or less than the threshold value. In addition, the refrigeration apparatus 10 regulates revolutions of the compressor 11 such that an evaporation pressure of the refrigerant, which flows through a refrigeration circuit 10A at a position downstream of an evaporator 14 and upstream of the compressor 11, the position being downstream of a downstream-end connection point of a liquid bypass flow path 16A, corresponds to a preset target evaporation pressure.

Abstract: A rotating electric machine comprises a field winding provided on a rotor iron core and a neutral ring supported independently of the field winding, wherein: the field winding and the neutral ring are electrically connected to each other through a connecting wire; the neutral ring is disposed spaced with respect to the rotor iron core; and the connecting wire absorbs the stress difference between the field winding and the neutral ring when a centrifugal stress is applied.

Abstract: There is described a read/write device which enables realization of miniaturization, a reduction in weight, improvement in the accuracy of step feed, and reliability. The read/write device includes heads, a carriage, a stepper motor for moving the carriage stepwise, and a medium drive motor for spinning a recording medium. The stepper motor further includes a rotor, a first stator which is formed from multilayer magnetic material and is fixedly positioned so as to surround the rotor, a second stator formed in substantially the same way as the first stator, and a holder for housing the first and second stators.
