Patents by Inventor Hiromichi Yamazui

Hiromichi Yamazui 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).

  • Patent number: 11145484
    Abstract: An analyzing apparatus includes a sample chamber, a measurement apparatus, and a gas cluster ion beam apparatus. A cooling body separates an ionization chamber of the gas cluster ion beam apparatus from a nozzle support to prevent heat emitted by an ionization filament from being transmitted to the nozzle support, and a temperature of a source gas emitted from a nozzle is kept at a constant temperature by a gas heating device while a sputtering rate is kept constant. A pressure of the source gas supplied to the nozzle is kept at constant pressure by a pressure controller, and a size of gas cluster ions is kept at a constant value. Because the sputtering rate is a constant value, highly accurate depth surface profiling can be performed.
    Type: Grant
    Filed: March 26, 2020
    Date of Patent: October 12, 2021
    Assignee: ULVAC-PHI, INC

  • Patent number: 9080947
    Abstract: [Object] The present invention provides an X-ray irradiation device capable of adjusting the energy of X-rays in a wide range, and an analysis device equipped with the X-ray irradiation device. [Solving Means] An X-ray irradiation device according to an embodiment of the present invention focuses X-rays emitted from an X-ray generation mechanism to a predetermined focal position by a focusing mechanism. The X-ray generation mechanism has a structure which generates a plurality of X-rays having different wavelengths. The focusing mechanism has a structure in which the plurality of X-rays are focused to the same focal position by focusing elements having diffraction characteristics suitable for the wavelengths of the respective X-rays generated by the X-ray generation mechanism.
