Title: Kichiji Misawa: Innovator in Automotive Noise Reduction Technologies
Introduction
Kichiji Misawa is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of automotive engineering, particularly in the area of noise reduction technologies. With a total of 4 patents to his name, Misawa's work has had a considerable impact on the design and functionality of automotive components.
Latest Patents
One of Misawa's latest patents is an air intake noise reduction apparatus for automotive vehicles. This innovative device effectively reduces air intake noise through a simple construction that requires a minimal number of components. The design features four air intake passages of varying lengths, which are created by connecting an upper wall and a lower wall of a noise reduction duct with three partition walls. By allowing pulsating air to interfere with one another, the apparatus reduces noise generated in the different passages, which are phase-shifted from one another. Additionally, the partition walls serve as reinforcement ribs, enhancing the duct's rigidity while minimizing intake air resistance.
Another significant patent is the motor vehicle intake muffler duct. This duct is formed by integrally bonding an upper duct, a lower duct, and a separator. It features three airways and seven muffler chambers, all of which are interconnected through vent holes in the separator. This compact structure allows for effective noise reduction while being formed from only three components, showcasing Misawa's ingenuity in automotive design.
