Latest Patents

One of Yokokawa's latest inventions is a nuclear magnetic resonance spectrometer, specifically the Fourier transform nuclear magnetic resonance spectrometer. This sophisticated device applies a pulse modulated radio frequency to a sample placed within a magnetic field. The resulting free induction decay signal is then Fourier transformed to obtain a nuclear magnetic resonance spectrum. A key feature of this invention is the use of a reference sample, such as tetramethylsilane, which has a known resonance peak. By adjusting the center frequency of the pulse-modulated radio frequency while keeping the magnetic field intensity constant, the frequency spectrum can reveal critical information about the receiving system employed in the spectrometer. This process leads to the determination of correction coefficients that enhance the accuracy of the signal strength displayed in the frequency spectrum.
