    摘要: A novel NiMnZn-based ferrite which can reduce magnetic loss (core loss) at a high frequency of about 2 MHz or higher and achieve higher saturated magnetic flux density while forming high sintered density is provided. The NiMnZn-based ferrite contains a main component comprising 54.0 to 57.5 mol % of iron oxide in terms of Fe2O3, 2.0 to 7.0 mol % of zinc oxide in terms of ZnO, 0.5 to 4.7 mol % of nickel oxide in terms of NiO, and a remainder of manganese oxide (in terms of MnO); and an accessory component comprising 100 to 1000 ppm by weight of Si in terms of SiO2, 800 to 3000 ppm by weight of Ca in terms of CaCO3, and 520 to 1000 ppm by weight of Nb in terms of Nb2O5 with respect to the main component; while having an average ferrite crystal particle size of 2.1 to 8.5 μm.

    摘要: A sphygmomanometer includes a body 10 and a cuff 20 which is integrally attached to the body 10 and wrapped around the wrist. The body 10 is attached to the cuff 20 such that the body is located on the thumb side of the arm L when the sphygmomanometer is fitted on the wrist. Consequently, a precise blood pressure measurement and precise blood pressure fluctuation can be obtained without restriction on the location where the blood pressure measurement is conducted.
