Latest Patents

Aizawa's latest patents include a filter designed for the treatment of carbon-based particles in exhaust gas. This filter is specifically engineered for diesel internal combustion engines, providing high throughput capacity, excellent durability, and favorable economic and maintenance properties. The filter is created by cutting an end face of a coiled material made from high-temperature resistant stainless steel, which is then processed to produce fibers. These fibers are gathered to form a web, which is sintered and heat-treated to create an alumina film on the surface. Additionally, electrodes are fixed to the free ends of the filter, allowing for the application of an electric current to generate heat when necessary.

Another significant invention by Aizawa is a catalyst combustor. This device includes a catalyst section for the combustion of fuel, a burner for preheating the catalyst, and a cross-flow type heat exchanger for preheating combustion air. A fan is also incorporated to feed air to the burner, enhancing the efficiency of the combustion process.
