  • Patent number: 10892698
    Abstract: In a current detection apparatus, an arm current detection unit detects each of at least first and second phase currents having respective amplitudes and flowing in a multiphase rotary electric machine based on a potential difference between input and output terminals of the corresponding one of first and second detection switches during the corresponding one of the first and second detection switches being on. A bus current detection unit detects each of at least bus-based first and second phase currents corresponding to the first and second phases of the multiphase rotary electric machine based on a current flowing through one of first and second buses. An amplitude correction unit corrects the first and second phase currents based on the bus-based first and second phase currents such that the amplitudes of the respective first and second phase currents match with each other.

  • Patent number: 10316439
    Abstract: The present invention provides a crimped polyamide yarn to which it is possible, using fibers that include low water absorption polyamide, to impart a stretch property and pliability such that it is possible for the inherent stretch properties of the crimped yarn to be appropriately expressed in a woven or knit fabric. The crimped polyamide yarn of the present invention is a side-by-side composite yarn which includes at least 40 mass % of low water absorption polyamide having an average of water absorption ratio of 5% or less at a temperature of 30° C. and a relative humidity (RH) of 90%, and in which the low water absorption polyamide is at least one component. The yarn is false-twisted, and has a crimp elongation ratio of 25% or more.
