Title: Innovations of Yukihiko Ito
Introduction
Yukihiko Ito is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of spark plug technology, holding a total of 3 patents. His work has been instrumental in enhancing the performance and efficiency of internal combustion engines.
Latest Patents
One of his latest patents is the "Heater Equipped Spark Plug." This invention features an insulator with a nose that holds a center electrode near the free end of an axial bore. It includes a lead wire along the insulator's surface and a heater formed on the insulator nose by baking a metal paste, which is connected to the lead wire. A high softening-point glass layer covers and secures the heater, with an alumina layer interposed for added stability. The alumina layer can have a thickness of 20-200 µm, while the high softening-point glass layer can range from 30-500 µm.
Another significant patent is the "Low-Voltage Type Igniter Plug Having a Semiconductor for Use in Jet and Other Internal Combustion Engines." This igniter plug features a center electrode with a firing tip, mounted within an insulator and an exterior metal shell. The ground electrode is either integral with or in electrical contact with the metal shell, creating a spark gap with the firing tip. An electrically semiconducting surface is positioned adjacent to the spark gap, formed by a sintered ceramic body with a high density of over 95 percent of its theoretical maximum. This design ensures uniform electrical characteristics and increased resistance to erosion from electrical discharges.
