Title: Masatoshi Kato: Innovator in Radioactive Waste Disposal and Circuit Substrate Technology
Introduction
Masatoshi Kato is a prominent inventor based in Osaka, Japan. He has made significant contributions to the fields of radioactive waste disposal and circuit substrate technology. With a total of 7 patents to his name, Kato's work reflects a commitment to innovation and environmental safety.
Latest Patents
Kato's latest patents include a method for the disposal of radioactive waste. This method aims to reduce the radiation level of waste until it can be reused as landfill, while also preventing the leakage of radioactive nuclides into the ground. The process involves a primary treatment step that transforms radioactive waste into a primary treated waste with a radiation level equal to or less than a reference value using a radiation shielding agent composed predominantly of a Ca-based inorganic compound. Following this, a secondary treatment step involves heating the primary treated waste to melt it, cooling it into glass granules, and sealing radioactive nuclides within the glass body.
Another notable patent is a method for forming images on object surfaces, including circuit substrates. This innovative approach reduces the exposure time of the photosensitive paste layer and enhances the exposure fineness of the layer. The process allows for the development of highly fine, high-density circuit substrates with thermal resistance at a reasonable cost. By applying a photosensitive paste containing photoresist and circuit material onto a substrate surface, Kato's method enables the formation of intricate circuit patterns through laser beam plotting.
