One of his latest patents is a calorimeter using a remanence type electromagnetic flowmeter. This invention includes a core made of a semi-hard or hard magnetic material, which has a property that allows the remanent magnetic flux density to vary in proportion to temperature. The design features a coil that is excited intermittently to magnetize the core, a metallic pipe forming a fluid path, and a yoke that conducts the remanent magnetic flux of the core. The yoke is fixed to the outer surface of the metallic pipe in close contact without forming an air gap, and a pair of electrodes is attached to the inner surface of the metallic pipe through an insulator.
Another significant patent is a magnetic field generating device for an electromagnetic flowmeter of the residual magnetization type. This device comprises a pair of first yokes with one of their end faces disposed opposite each other on both sides of a magnetic gap that includes a fluid conduit made of a non-magnetic material. A core is positioned between the other end faces of the first yokes, and a coil is wound around the core. Additionally, at
