Latest Patents
One of Tsugita's latest patents is an "Alloy target for manufacturing a magneto-optical recording medium." This invention involves an alloy containing 10 to 50 atom % of at least one rare earth element selected from Sm, Nd, Gd, Tb, Dy, Ho, Tm, and Er, with the balance consisting substantially of at least one transition metal such as Co, Fe, or Ni. The alloy features a mixed structure composed of at least three phases of intermetallic compounds formed by the rare earth element and the transition metal.
Another significant patent is the "Process for producing alloy powder containing rare earth metals." This process produces an alloy metal powder with a uniform composition and minimal residual reducing agent and oxygen. The method involves preparing a mixture of rare earth metal oxide powder, a metal powder that is difficult to volatilize at high temperatures, reducing agents, and alkali metal or alkaline earth metal chlorides. The mixture is then heated in an inert gas atmosphere or under vacuum to create a reaction mixture, which is treated by a wet process.
