Title: Innovations by Yoshitaka Ohyama
Introduction
Yoshitaka Ohyama is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of manufacturing and materials science, particularly through his innovative approaches to degreasing methods.
Latest Patents
Ohyama holds 3 patents, with his latest inventions focusing on advanced degreasing techniques. One of his notable patents is a water solvent extraction degreasing method. This method is designed to reduce degreasing time while minimizing issues related to abrupt decomposition, vaporization, and swelling caused by heat. It involves the removal of an organic binder from a molded product, which is produced by mixing a powder material with the organic binder. The organic binder contains at least one water-soluble organic compound and one water-insoluble thermoplastic resin. The degreasing process utilizes water as a solvent to extract the water-soluble organic compound from the binder.
Another significant patent by Ohyama is a thermal decomposition degreasing method. This low-cost method drastically reduces the time required for the degreasing process, which involves heating, vaporization, and thermal decomposition. It ensures the shape retention of injection molded products during the degreasing process. The method consists of two steps: the first involves heating the molded product under reduced pressure to partially evaporate the thermoplastic binder, while the second step heats the product at a higher temperature in an inert gas atmosphere.
