With a total of 6 patents to his name, Imai's work showcases his innovative approach to engineering and design.

Latest Patents

One of Imai's latest patents is a method of manufacturing a metal ring for an endless metal belt. This invention focuses on creating a metal ring with reduced stress concentration, which facilitates the manufacture and maintenance of a rolling roller. The process involves forming a mesh-like unevenness on the surface of an inner circumference rolling roller, which is achieved by rotating the roller at a specific speed while moving a grinder back and forth. The grain size of the grinder used ranges from #270 to #1000. This method ensures that the unevenness transferred onto the metal ring is narrow and random, enhancing its lubricity. Additionally, the metal ring undergoes solution treatment and nitriding treatment, resulting in a product with high compressive residual stress and improved toughness.

Another significant patent involves a molten salt composition for manufacturing laminated rings. This process produces a laminated ring for use in continuously variable transmissions by welding the ends of a sheet of maraging steel. The rings are then nitrided in a salt-bath nitriding process, which involves dipping them in a molten salt mixture and heating them to specific temperatures. The final product is a stacked laminated ring that meets the demands of modern engineering.
