Title: Tsuneo Kitamura: Innovator in Synthetic Resin Technology
Introduction
Tsuneo Kitamura is a notable inventor based in Ashiya, Japan. He has made significant contributions to the field of synthetic resin technology, particularly through his innovative methods of moulding foamed synthetic resin pellets.
Latest Patents
One of Kitamura's key patents is titled "Method of moulding foamed synthetic resin pellets of polyolefine." This patent describes a method where synthetic resin pellets are prepared with a volume of closed cells exceeding 65% of the total volume. The process involves using an inorganic gas in the cells at a pressure higher than 1.18 atmospheres. The pellets are then filled into a mould that is not completely gas-tight and heated to expand and adhere tightly to each other. The method allows for the pressure in the mould to be lower than ordinary pressure or even at a vacuum, while the resin can be at a pressure higher than ordinary pressure. The moulded product can be removed from the mould after cooling or during cooling when the inner temperature is between its melting point and 50 degrees Celsius below the melting point. The final product can be stored at temperatures ranging from 30 to 70 degrees Celsius below the melting point. Kitamura holds 1 patent in this area.
