Kenji Katagiri 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: 8182610
    Abstract: Equipment is realized which is capable of increasing the frequency of use of a deposition mask of an organic EL element and the recycle of an adhesive agent by efficiently cleaning the deposition mask with little damage and efficiently collecting the adhesive agent. A pulse laser is irradiated to a deposition mask to separate the deposition agent from the deposition mask. The separated deposition agent is sucked by a suction nozzle, and the deposition agent is separated from air by a cyclone and deposited on a bottom of the cyclone. Thereafter, a first valve is opened to collect the deposition agent in a deposition agent collection section. Then a second valve is opened to move the deposition agent to a deposition agent refining section to be refined. A third valve is opened to store the refined deposition agent in a deposition agent storage section. The deposition mask may be cleaned without being damaged to collect the deposition agent with high efficiency.
    Type: Grant

  • Patent number: 6745707
    Abstract: A method of disposing of combustible materials. The method includes the steps of: providing a heating space; providing a first source to generate heat to a first predetermined level at a first location in the heating space sufficient to reconstitute the combustible materials to a molten slag at the first location and so that heat generated by the first source elevates the temperature at a second location within the heating space to a second predetermined heat level that is below the predetermined heat level and high enough to cause combustion of the combustible materials; directing combustible materials to the second location at which the combustible materials are combusted to produce ash; and causing the ash to be directed to the first location to be reconstituted as molten slag.
