Latest Patents
Izuoka's latest patents include a low-voltage type igniter plug featuring a semiconductor structure designed for use in jet and other internal combustion engines. This igniter plug comprises a semi-conducting body mounted adjacent to a spark-gap, which is in electrical contact with both center and ground electrodes. The body essentially consists of silicon carbide particles less than 5 microns in average diameter and alumina particles less than 1 micron in average diameter. The weight percentages of the silicon carbide particles range from 65 to 80, while the alumina particles range from 20 to 35. These materials are mixed with a suitable binder and hot pressed at temperatures above 1800 degrees Celsius and pressures exceeding 200 Kg/cm².
Another notable patent is the igniter plug structure featuring semicircular grooves. This invention provides an igniter plug with a plurality of grooves within the outer surface of an annular ground electrode, which has a reduced diameter of about 13 mm. Each groove is generally semi-circular in cross-section, allowing for improved airflow along the grooves. The design includes between 4 to 16 grooves, each with a width of approximately 1.0 mm to 2.5 mm. The semi-circular cross-section enhances cooling efficiency without increasing machining requirements.
