Nuclear magnetic resonance device
First Claim
1. A nuclear magnetic resonance apparatus comprising:
- nuclear magnetic resonance means for elucidating atomic configuration and molecular structure of a substance based on a decay signal of induced electromotive force caused by resonance precession of nuclear magnetic moment induced by irradiation of electromagnetic pulses in an RF region when the substance is exposed to a strong magnetic field; and
a vibration isolation mechanism for suppressing vibration of this nuclear magnetic resonance means, wherein the vibration isolation mechanism has an air spring as an actuator, the air spring being connected to a pressurized air source via an electro-pneumatic converter and acting to exert a force for vibration isolation on the nuclear magnetic resonance means, and the vibration isolation mechanism is formed so as to be capable of active vibration isolation, and disposed away from the nuclear magnetic resonance means by such a distance that the electro-pneumatic converter never incurs any malfunctions or operating failures under influence of a magnetic field generated by the nuclear magnetic resonance means.
