摘要： A uniform magnetic field generating device for generating a uniform magnetic field such as that required in a nuclear magnetic resonance device is disclosed. In prior art devices, in order to obtain a highly uniform magnetic field space, a parallel gap has been formed between pole pieces which were magnetically homogenized and mounted on magnets coupled by a yoke. In place of such pole pieces, a magnetically homogenized pole block or a pole block sandwiched by pole pieces is inserted between the magnets and a cylindrical hole or space is formed in the pole block, a sectional area of the space taken in parallel with the direction of a magnetic field due to the magnets and perpendicular to the axial line of the space being of circular, ellipse or rectangular shape, whereby a highly uniform magnetic field space is established.

摘要： In a nuclear magnetic resonance spectrometer, this invention relates to an improvement of a lock system for stabilizing a magnetic field intensity. It is an object of the present invention to dissolve a low stability by using a conventional voltage control oscillator and a complex operation in the case of varying a reference material for locking. In the present invention, a radio frequency of a high stable reference frequency source is demultiplied by a variable frequency divider so that a frequency modulation or a modulation of the magnetic field is effected by the output thus demultiplied. When the reference material is changed, the operation can easily be made by varying the demultiplication ratio of the variable frequency divider.
