Latest Patents

Sekizawa's latest patents include innovative designs for spark plugs aimed at reducing variation in discharge points. The first patent describes a spark plug that features a center electrode, a metal shell that insulates and holds the center electrode, and a ground electrode. This ground electrode consists of a base material with one end connected to the metal shell and a tip that has a discharge surface opposed to the center electrode. The discharge surface is uniquely designed with a quadrangular shape and is chamfered on all four sides, with a specific C chamfer on one side.

The second patent presents a spark plug that includes a ground electrode with a base material and a tip that has a discharge surface. This design incorporates a melt portion that joins the tip to the base material, creating a spark gap between the center electrode and the discharge surface. Notably, the tip features a thin portion in its inner area, where the distance between the discharge surface and the melt portion is shorter than in the outer peripheral portion, enhancing its performance.
