Latest Patents

One of Nakajima's latest patents is an advanced oxygen sensor. This device features a platinum reference electrode positioned on the surface of a blind bore formed in a solid zirconia electrolyte body. It includes two semi-cylindrical measuring electrodes, one made of platinum and the other of gold, located on the outer surface of the body. The design incorporates a first annular insulator that supports the body within the casing, creating two chambers on either side. A second annular insulator presses lead wires against the measuring electrodes, while a cylindrical connector ensures a reliable electrical connection between the platinum reference electrode and a lead line. The sensor allows atmospheric air to enter one chamber and exhaust gases to enter the other, enabling the electrodes to produce distinct signals that are used for recalibration over time and temperature.

Another notable patent involves an internal combustion engine (I.C.E.) equipped with a temperature maintenance system for the reactor. A temperature sensor is strategically placed at the upstream or middle portion of the reactor to oxidize unburned constituents in the exhaust gases from the engine's combustion chambers. The air-fuel ratio is controlled to maintain the reactor's temperature at a predetermined level, ensuring optimal performance and emissions control.
