  • Patent number: 11933865
    Abstract: A magnetic resonance member 1 includes a crystal structure and is capable of electron spin quantum operations with microwaves of different frequencies corresponding to arrangement orientations of a vacancy and an impurity in a crystal lattice. A magnetic field transmission unit 4 senses a measurement target magnetic field at plural measurement positions different from each other, and applies application magnetic fields corresponding to the measurement target magnetic field sensed at the plural measurement positions to the magnetic resonance member 1 along respective different directions corresponding to the aforementioned arrangement orientations. A measurement control unit 21 controls a high frequency power supply 12, and determines detection values detected by a detecting device (an irradiating device 5 and a light receiving device 6) of the physical phenomena corresponding to the plural measurement positions.

    Abstract: A massaging device having an applicator driven by a plurality of driving unit to move along two or more different axes to generate a combined massaging action to be applied to the user's body. A controller holds individual speed data each defining a speed at which each of the driving units reciprocates the applicator along each of the different axes, and to control the driving units to reciprocate the applicator in accordance with the associated speed data. The controller controls the speed of the applicator along one of the axes independently from the speed of the applicator moving along another of the axes. Accordingly, the applicator's movements along the different axes can be free from being interfered with each other even being subject to a load, thereby assuring to continue the combined massaging action.
