Title: Hiroyuki Tanaka: Ignition Coil Invention
Introduction
Hiroyuki Tanaka is an inventor associated with Hitachinaka, Japan. His patent work includes an ignition coil designed for use in an internal combustion engine.
Latest Patents
Tanaka’s listed patent, “Ignition Coil for Use in Internal Combustion Engine,” concerns an individual ignition system in which a center core, secondary coil, and primary coil are arranged concentrically inside a coil case, with insulating resin filling the spaces around the components.
The invention addresses the bonding between the resin and the synthetic-resin bobbins that support the coils. It specifies removing the skin layer from at least the inner surface of the primary bobbin and the outer surface of the secondary bobbin, allowing the insulating resin to adhere closely to those surfaces. The improved bond is intended to increase resistance to thermal shock and help maintain the coil’s insulation performance. Tanaka is credited with 1 patent.
