Latest Patents

Matsuzawa's recent innovations include the development of an Au-based clad composite material and its production method. This invention aims to enhance the performance and longevity of micromotors. By providing a contact material suitable for a commutator, the Au-based clad composite material incorporates an Ag–Cu–Si alloy layer, cladded with gold or a gold alloy. This design features a dispersed intermetallic compound Cu–Si, which significantly improves wear resistance and prolongs the lifespan of micromotors.

Additionally, Matsuzawa developed a novel method for producing an Ag–ZnO electrical contact material, which uniformly disperses ZnO micrograms in silver. This method preserves low contact resistance while enhancing welding resistance and wear resistance. It begins with casting silver and zinc in precise proportions, followed by internal oxidation to ensure uniform dispersion, compacting the oxidized chips into billets, and finally, pressing and sintering them to achieve exceptional material properties.
