Abstract: The present invention provides a high-strength steel sheet, which can be used in various applications including automobile parts and exhibits excellent collision safety and excellent moldability, and a method for manufacturing the high-strength steel sheet. The high-strength steel sheet according to an aspect of the present invention satisfies a predetermined chemical composition and has a metallographic microstructure having ferrite fraction: 0% to 10%, MA fraction: 0% to 30%, hard phase other than ferrite and MA: 70% to 100% in terms of area proportion and retained austenite fraction: 5% to 30% in terms of volume proportion, and in the high-strength steel sheet, the skewness of IQ as analyzed by the EBRD method is ?1.2 to ?0.3 when the skewness is expressed by a predetermined relational expression in a case where crystal grains having a bcc structure and a bct structure are regarded as an aggregation of regions having an area of 0.05 ?m2.

Abstract: A roller type chassis dynamometer includes: a hollow roller to be driven by a material to be inspected; a rotatable shaft having its axis extending in concentric alignment with the axis of the hollow roller and having its outer peripheral surface which defines an annular space therearound with the inner peripheral surface of the hollow roller; a power absorbing means positioned within the annular space and secured on said rotatable shaft, the power absorbing means absorbing a power to be transmitted to the roller; and detecting means associated with the rotatable shaft for detecting a power absorbed in the power absorbing means, the power absorbing means having an exciting coil provided with a lead wire running through an axial bore extending through the rotatable shaft, to the exterior of the dynamometer, to be connected to a power source, whereby the exciting coil may produce a given braking torque by controlling an electric current to be supplied thereto, commensurate with the actual condition of a materia

Abstract: A rotary electric machine comprising a plurality of magnets with magnetic poles made of different B-H characteristics is disclosed in which a magnet with high coercive force is arranged on the portion of each pole where the magnetic field is weakened and a magnet with high magnetic flux density on the portion of each pole where the magnetic field is strengthened or little weakened.
