Toru Serizawa 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).

  • Thermoplastic elastomer composition, insulating glass using the composition, process for producing the insulating glass and nozzle for producing the insulating glass
    Patent number: 6911103
    Abstract: A thermoplastic elastomer composition produced from a thermoplastic resin and rubber and having a dispersion phase formed of a rubber composition at least part of which is dynamically crosslinked in the continuous phase of the thermoplastic resin, insulating glass using the thermoplastic elastomer composition as a sealing material and spacer, a process for producing the insulating glass using a sealing material made from the thermoplastic elastomer composition, comprising the steps of inserting the leading end of a charging nozzle into a space between the peripheral portions of a plurality of glass sheets, discharging the sealing material from the leading end of the nozzle body at a predetermined rate, and moving the glass sheets or the nozzle body relative to each other to charge the sealing material made from the thermoplastic elastomer composition into the space between the peripheral portions of the glass sheets, and a nozzle used in this process.
