LCR Auto tuning apparatus and method of LCR circuit using the variable inductance detection coil for Nuclear Quadrupole Resonance and Nuclear Magnetic Resonance

摘要

The present invention is automatically adjusted in the LCR circuit that includes the coil and the coil to observe the resonance signals of the pole resonance and nuclear magnetic resonance of the hex, a coil capable of changing the inductance in a state suitable for the resonance signal frequency of an object of a coil, and to observe the resonance signals of the various types of objects, and LCR circuit for automatically tuning by the pole 0 people of hex and nuclear magnetic resonance to allow to observe the resonance signals of the object sequentially inductance variable detection coil the LCR circuit relates to a automatic tuning apparatus and method, a coil 13 of a springy material, the coiled coil insertion portion 14 to be 13 is inserted, the coil is connected to one end of the coil 13, the length by adjusting plunger 16, the coil length adjusting plunger (16) moved by the coil length adjusting drive system (19) for adjusting the overall length of the coil 13, the coil 13, one fixed contact 17, the variable contact point transfer cover 15, which supports the variable contact point 18, and the variable contact point 18, which is connected in a sliding way to the coil 13 connected to the end, of the variable inductance is connected to a contact feed cover (15) by moving it consists of the variable contact point adjustment driving system 20 for adjusting the length of the actual use of the coil 13, a variable detection coil; And third, based on the current value of the variable current meter 22 connected to the capacitor 27. Capacitor adjusting drive system (21) for adjusting the oscillator (23) for generating an AC voltage, a resistance 28, and the ammeter 22 control circuit 24 for controlling the two driving system (19, 20, 21), characterized in that it comprises a storage device 25 and temperature sensor 26 coupled to the control circuit 24. Accordingly, it is possible to observe the pole resonance and nuclear magnetic resonance signal of the hex of the various objects in a single detection coil, it is possible to quickly observe the resonance signals by tuning the LCR circuit including the detection coil automatically, also, several It has the advantage that it can observe the extreme resonance signals in sequence of the hex of the object.
