  • Process for hydrolyzing and recycling a polyurethane
    Patent number: 6630517
    Abstract: A process for hydrolyzing and recycling polyurethanes as target compounds to be hydrolyzed into raw materials or derivatives thereof for the target compounds, comprising bringing pressurized water in a liquid state at a temperature of 190 to 370° C. into contact with the target compounds in a reactor to hydrolyze the target compound; followed by post-processings, such as dewatering, addition, distillation, separation, and liquid separation for a hydrolyzed reaction product discharged from the reactor.
    Type: Grant
    Filed: October 7, 1999
    Date of Patent: October 7, 2003

  • APPARATUS AND METHOD FOR DECOMPOSING AND RECOVERING ISOCYANATE COMPOUND
    Publication number: 20030012710
    Abstract: The present invention relates to an apparatus for hydrolyzing and recycling polyisocyanate derivatives having at least one isocyanato group and/or a group derived from an isocyanato group as target compounds to be hydrolyzed into raw materials or derivatives thereof for the target compounds, the apparatus including: a hydrolyzer for bringing only pressurized water in a liquid state at a temperature of 190 to 370° C. into contact with the target compounds in the reactor to hydrolyze the target compound; and a post-processor for conducting post-processings such as dewatering, addition, distillation, separation, and liquid separation for a hydrolyzed reaction product discharged from the reactor.

  • Mobile telecommunication apparatus having notches
    Patent number: 6314273
    Abstract: A mobile telecommunication apparatus reduces current around a control circuit on a printed circuit board so as to lessen background noise and to improve the radiation characteristic. The mobile telecommunication apparatus includes a printed circuit board located in a body of the mobile telecommunication apparatus; a radio circuit including a modulator circuit and a demodulator circuit arranged on the printed circuit board; a control circuit including a voice circuit for processing a voice signal arranged on the printed circuit board; a first earth conductor for grounding the radio circuit; a second earth conductor for grounding the control circuit and being continuous with the first earth conductor; an antenna connected to the radio circuit; and a slit arranged between the first earth conductor and the second earth conductor.
