Hiroaki Katsumura 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).

  • Vacuum heat insulating material, method of producing vacuum heat insulating material, and heat insulating box body using vacuum heat insulating material
    Patent number: 8753471
    Abstract: Disclosed is a vacuum heat insulating material. Also disclosed is a heat insulating box using the vacuum heat insulating material. The vacuum heat insulating material includes a core member and envelope members having gas-barrier properties and including heat-seal layers. The envelope members are opposed to each other in such a manner that the core member is disposed between the heat-seal layers. The envelope members are entirely heated to a temperature at which the heat-seal layers are melted, and the heat-seal layers are heat sealed to each other by applying uniform pressure to the entire envelope members from outside to inside the envelope members.
    Type: Grant
