Latest Patents

One of Sakaida’s inventions is a mold for molding optical discs. It uses two mold members that come together to form a cavity, along with a detachable disc-shaped stamper seated on a flat surface. That surface is provided by a plate-like sintered ceramic member secured to the second mold body. The ceramic’s high hardness is intended to help protect the seating surface from damage during prolonged use.

Another invention is a highly thermally conductive and electrically insulating substrate. It combines a metal plate, such as aluminum, with a film made from metal oxide particles dispersed in an adhesive organic polymer. The design addresses the limited heat conduction and heat dissipation of substrate materials used in wiring boards and heat sinks.
