Patents by Inventor Takeo Mimori

Takeo Mimori 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).

  • Adsorbent for adsorption of radioactive nuclides and method of producing the same, and process for volume-reduction treatment of radioactive waste
    Patent number: 5707922
    Abstract: An adsorbent for radioactive nuclides incorporating fibrous activated carbon. The adsorbent includes fibrous activated carbon having good adsorption performance, inorganic fiber and inorganic binder. Therefore, the adsorbent exhibits good shape stability when it is formed into a molded piece, has good combustion performance, and is not liable to scattering of radioactive nuclides adsorbed thereon when it is incinerated.
    Type: Grant
    Filed: June 19, 1996
    Date of Patent: January 13, 1998
    Assignees: Japan Atomic Energy Research Institute, Unitika Ltd.

  • Adsorbent of radioactive nuclides and process for volume-reduction treatment of radioactive waste
    Patent number: 5476989
    Abstract: An adsorbent useful for the adsorption of radioactive nuclides which comprises fibrous active carbon having a specific surface area of 1,000 m.sup.2 /g or more and an equilibrium moisture regain of 10% or more at a relative humidity of 45%; and a process for the volume-reduction treatment of radioactive liquid waste which comprises subjecting radioactive liquid waste containing radioactive nuclides to an adsorption treatment using an adsorbent comprising fibrous active carbon having a specific surface area of 1,000 m.sup.2 /g or more, and subsequently subjecting the spent adsorbent to an incineration treatment at a temperature which is equal to or higher than the ignition point of the fibrous active carbon.
