  • Patent number: 9492094
    Abstract: In a blood pressure monitor, when a main unit is mounted on a mounting surface such as a desk, a bulging region of a first tube and a bulging region of a second tube, both located at a rear surface of the main unit, come into contact with the mounting surface. This can avoid the main unit from sliding even when the main unit is pulled by the first and second tubes. Consequently, a blood pressure monitor has a configuration in which the main unit is less likely to slide over the mounting surface even when the main unit is pulled by tubes connected to the main unit.

  • Patent number: 9385581
    Abstract: The present invention is intended to provide a magnetic gear structure that realizes a magnetic gear that transmits a torque efficiently by reducing eddy currents generated in the interior of magnets. In order to solve the subject described above, in the magnetic gear structure, a structure in which magnets are arranged in the interior of an iron core in an inner rotor portion. Bonded magnets formed by molding, for example, NdFeB powder may be used as the magnets. Since the influence of the eddy current on the side of an outer rotor having a larger pole number is large, a structure in which the magnets are arranged in the interior only of an outer rotor portion having a larger pole number is also applicable. In addition, the magnets to be embedded may be divided into a plurality of pieces. The finer the division of the magnets, the less eddy currents are generated, so that a method of further fining down and assembling the same is also effective.
