Patents by Inventor Leo Matsuoka

Leo Matsuoka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Selective molecular excitation method and isotope separation method using the same, isotope analysis method, selective molecular excitation apparatus and isotope separation apparatus
    Patent number: 8247762
    Abstract: Molecules of a specific species can be selectively excited among molecules of a plurality of species that show only a slight difference of mass. Energy levels can be displayed on a graph where the horizontal axis indicates excitation energy. Assume an instance where an electromagnetic wave showing a comb-shaped spectrum having a plurality of narrow bands as indicated by P1 through P14 and tuning with excitation energies corresponding to the rotational levels of molecule X is irradiated onto the molecule X. The molecule X can sequentially make transitions to higher energy levels by using an electromagnetic wave showing such a comb-shaped spectrum. The energy levels of molecule Y are not synchronized with the comb-shaped spectrum. The two ranges of Y4 through Y7 and Y12 through Y15 operate as gates and the molecule Y cannot make transition from a rotational level to another when a gate is found between them.
