Latest Patents

One of Tamaki's latest inventions is the electro-pneumatic air pressure regulator. This device features a primary pressure introduction port, a secondary pressure output port, and a pilot pressure chamber. It includes a main valve that opens and closes a communicating conduit, along with a floating piston that actuates the main valve. The design incorporates a nozzle conduit that connects the pilot pressure chamber to the atmosphere, a flapper with a leaf spring, and an electromagnetic drive system that adjusts the flapper's position based on an analogue input signal. The flapper is designed with a conical projection that fits into a corresponding recess on the nozzle conduit, optimizing airflow control.

Another significant invention by Tamaki is the air-spring vibration isolation device. This device consists of a stationary housing and a movable top plate positioned above it. An airtight flexible member creates a pressure chamber between the two components. The device allows for vertical movement of the top plate by varying the internal pressure of the chamber. Additionally, it features a vibration-free movable base with a dome-shaped contacting portion that enhances stability and performance.
