    • In a refrigeration cycle device with a capacity-variable compressor, a preset suction pressure that serves as a target value of a refrigerant suction pressure of the compressor is calculated and a refrigerant discharge capacity of the compressor is controlled by operating a capacity varying portion such that the suction pressure of the compressor is appreciated to the preset suction pressure. A thermal load detection portion is configured to detect a thermal load of a refrigeration cycle, and a refrigerant flow amount detection portion is configured to detect a flow amount of refrigerant circulating through the refrigeration cycle. In the refrigeration cycle device, a pressure at a predetermined part of the compressor is estimated based on the thermal load detected by the thermal load detection portion and on the flow amount detected by the refrigerant flow amount detection portion.

    • A strain detector in which a pair of magnetic layer patterns (5, 6) made of a magnetically permeable soft magnetic material are attached to a driven shaft (1) and a pair of detection coils (8, 9) are disposed to surround the respective magnetic layers for detecting a change in magnetic permeability of the magnetic layers which is caused when an external force is applied to the driven shaft. A magnetic yoke (15 or 16) is disposed around each of the detection coils (8 or 9) for promoting the passage of the magnetic flux therethrough, thereby decreasing flux leakage. The magnetic yokes (15, 16) each comprises an axially extending tubular member (15a) and radially inward outer and inner flanges (15d, 15e) extending from axially outer and inner ends of the tubular member, respectively. The magnetic yokes each may be made of a compacted core material containing magnetic powder and binder or assembled from a plurality of parts. A highly electrically-conductive, non-magnetic material (23) may be disposed directly between the inner ends (21b ) of the tubular member (21a) of the magnetic yokes (21) and the detection coils (8, 9) for magnetically isolating them without the need for any inner flange while allowing a compact structure.
