Latest Patents

Sakuma holds a patent for a method of manufacturing a permanent magnet. This method involves applying a permeating material, which includes metal particles and a flux, to the curved surface of a magnet. The magnet is then placed in a furnace under vacuum or inert gas conditions to volatilize the solvent in the flux. The process includes heating the permeating material to a temperature range of 300 to 500 degrees Celsius, allowing the flux to carbonize and form reticulated carbon. Subsequently, the temperature is increased to between 500 and 800 degrees Celsius to melt the metal particles, enabling them to permeate the magnet uniformly through the reticulated carbon. This innovative approach enhances the performance and durability of permanent magnets.
