Patents by Inventor Tomoki Ohashi

Tomoki Ohashi 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).

  • Extractor chemical analyzer and chemical analyzing method
    Patent number: 7662340
    Abstract: The invention is achieved by feeding a reagent using centrifugal force, without providing a valve for controlling the flow rate of the reagent in the reagent flow path. A chemical analyzer is used which comprises a structure that is supported so as to be rotatable, said structure comprising a capturing section for capturing specific chemical substances from a specimen, specimen containers and reagent containers including washing solution containers.
    Type: Grant
    Filed: December 28, 2001
    Date of Patent: February 16, 2010
    Assignee: Hitachi High-Technologies Corporation
    Inventors: Yoshihiro Nagaoka, Naruo Watanabe, Teruhisa Akashi, Yuji Miyahara, Kei Takenaka, Tomoki Ohashi
  • Chemical analysis apparatus and genetic diagnostic apparatus
    Patent number: 7384602
    Abstract: In a chemical analysis apparatus for extracting a specific substance, such as nucleic acid, from a sample containing a plurality of chemical substances, solutions remaining in valves are prevented so that a reagent in an earlier step does not contaminate the subsequent steps. Predetermined quantities of solutions are carried and supplied by centrifugal force without providing valves for controlling the flow of the solutions. After perforating the lids of ventilation holes 272, 273, 274 communicated with a detection container 450 and disposal containers 460 and 470 in an analysis disc 2, the analysis disc 2 is rotated to supply and carry a predetermined quantity of the sample.
