Latest Patents
One of his latest patents is a spark plug featuring an insulator with a unique shape. This spark plug includes a center electrode with a large-diameter portion that has the largest outside diameter in the center electrode. The large-diameter portion is securely retained at a rear-facing surface within an axial hole of the insulator. Additionally, the metal shell of the spark plug has a diameter-increased portion on the rear end side, which has an inside diameter that increases toward the rear end. The insulator's first portion, located from the rear end of the rear-facing surface to the front end of the diameter-increased portion, has a maximum thickness in this region and is positioned on the outer periphery of the large-diameter portion. Another patent describes a spark plug where the insulator is held by a metal shell via a packing. This packing consists of a base material and a metal layer formed on the surface of the base material. The design ensures that the distances between specific points on the metal layer and the insulator's contact surface are optimized for performance.
