摘要： A switching operation is performed on a switching element of a power-factor improving unit that includes a reactor. An output voltage of the power-factor improving unit is set to a load voltage by switching on and off the switching element based on a result of comparison between an input current and an input-current reference signal of a power-supply voltage waveform. A zero cross of an alternate-current power supply is detected, and the switching operation is performed on the switching element a predetermined number of times based on a detection of the zero cross.

摘要： A magnetic pre-pressurizing section for pre-pressurizing the inner ring of the bearing in the axial direction by a difference of magnetic forces of permanent magnets of the two rotors is arranged. The magnetic pre-pressurizing section is constructed by a difference of a magnetizing amount for forming permanent magnets 8b, 9b arranged in the respective rotors. The magnetic pre-pressurizing section is also constructed by a difference of distances of an air gap L1 of a stator 2 and a permanent magnet 8b1, and an air gap L2 of the stator 2 and a permanent magnet 9b1. The magnetic pre-pressurizing section is also constructed by a difference of thicknesses of the rotating axis direction of a permanent magnet 8b1 and a permanent magnet 9b2 arranged in the respective rotors.

摘要： A two-stage rotary compressor includes a sealed cylindrical compressor housing that includes first, second and third communication holes separately arranged sequentially in an axial direction on an outer peripheral wall, an accumulator held on an outer side of the housing, a low-pressure connecting pipe that connects a bottom communication hole of the accumulator and the second communication hole, and an intermediate connecting pipe that connects the first and third communication holes. The second and third communication holes are arranged at nearly the same circumferential direction position of the housing. The accumulator is held at nearly the same circumferential direction position as the second communication hole. The first communication hole is arranged at a circumferential direction position different from the second and third communication holes to ensure that the low-pressure connecting pipe and the intermediate connecting pipe two dimensionally bent in a circular arc shape do not interfere with each other.
