Abstract: Disclosed is a measurement method for measuring a test substance contained in a biological sample based on a predetermined measurement principle, comprising acquiring a first measured value of the test substance using a first measurement reagent, and operating the first measured value to an arithmetic value when measured using a second measurement reagent different from the first measurement reagent, by using arithmetic information designed to make a first cut-off value for the measured value obtained using the first measurement reagent correspond to a second cut-off value for a measured value obtained using the second measurement reagent.

Abstract: An outer rotor type electric motor is provided in which a ring-shaped yoke made of a magnetic metal is secured to an inner periphery of a plate-shaped rotor case, and includes a rotor in which a resin bonded permanent magnet is mold bonded to an inner peripheral face of the yoke, wherein an engagement portion (25a) that bites into and engages with the rotor case (23A) is formed integrally with and connected to the resin bonded permanent magnet (25). This can reliably prevent relative rotation of a resin bonded permanent magnet with respect to a rotor case when a rotor is rotating.
