摘要： A resonator which is capable of modulating frequencies has a main body having a vibrating body and an elastic supporting body supporting the vibrating body and a frequency modulating unit having a movable contacting part that is movable between a first position away from the elastic supporting body and a second position which is contactable with the elastic supporting body. Since there is a variable vibration length of the elastic supporting body during vibration of the vibration body by the contact between the contacting part and the elastic supporting body, it is possible to change the frequency of vibration extracted from the resonator, when it is necessary.

摘要： A non-invasive blood glucose measurement method using a magneto-resonance absorption method. A constant magnetic field is applied using a pair of permanent magnets, the magnetic field having a uniform strength. A triangular waveform low frequency modulation magnetic field is applied using a low frequency generator and a pair of low frequency coils, the low frequency modulation magnetic field having a uniform strength. A weak acoustic wave modulation magnetic field is applied using an acoustic wave generator and a pair of acoustic wave coils. Electromagnetic waves are applied to a detector in which a finger is positioned to produce a nuclear magneto-resonance, the electromagnetic waves having a frequency varying in a specific frequency band step by step, the applying being done using a high frequency generator and a sensor coil. A magneto-resonance absorption signal produced by spin-lattice relaxation of protons in a tissue of the finger because of the nuclear magneto-resonance is detected. A magneto-resonance spin-lattice relaxation time of the finger from the magneto-resonance absorption signal is determined. A blood glucose concentration in a human body is determined from a correlation between a pre-determined blood glucose concentration in the human body and the determined magneto-resonance spin-lattice relaxation time.
