Latest Patents
One of Kotanshi's latest inventions is the Combined Display Panel. This transparent electroluminescent display panel overlaps with a conventional instrument panel, forming a combined display panel assembly. The design allows for selective display of overlapping front and back panel displays. The front panel can show additional information, such as navigation maps, and is turned off when not needed, while the back panel remains on. This invention effectively eliminates undesirable reflections from the back panel when the front panel is active, thanks to a light attenuator that reduces light intensity between the panels.
Another significant patent is the Laminated Piezoelectric Transducer. This device consists of a laminate of multiple piezoelectric plates with paste electrodes inserted between them. Metal extrusions are formed on the outer surface of the laminate through electroless plating, allowing for electrical connections between alternate paste electrodes. This design enables the formation of paste electrodes on the main surfaces of the piezoelectric plates, eliminating the need for traditional metal plate electrodes.
