    摘要： A process for producing an aliphatic polyester by subjecting a cyclic ester to ring-opening polymerization, which comprises adding water to a cyclic ester purified to the extent that a water content is at most 60 ppm to control an overall proton concentration in the cyclic ester, thereby controlling at least one physical property among melt viscosity, molecular weight and yellowness index of the resulting aliphatic polyester.

    摘要： A magnetostrictive torque sensor includes a rotating shaft that is rotated by an applied torque, magnetostrictive films formed around the entire circumferential periphery of a surface of the rotating shaft in at least one location, sensor coils for sensing a change in impedance of the magnetostrictive films, and a torque calculation unit for calculating the torque applied to the rotating shaft on the basis of a signal relating to the change in impedance outputted from the sensor coils. In this magnetostrictive torque sensor, a width of the magnetostrictive films in the axial direction of the rotating shaft and a width of the sensor coils in the axial direction of the rotating shaft are set so as to fulfill the relationship 1
