Latest Patents

Sugishita’s listed patents address the structure and manufacture of conductive materials for electrical connections.

“Conductive Material for Connecting Part and Method for Manufacturing the Conductive Material” describes a copper-strip base with a copper–tin alloy layer and a tin covering layer. The design allows portions of the alloy layer to remain exposed through the tin surface, with the exposed area controlled within a specified range. The patent describes this layered structure as a way to tailor the material’s surface characteristics.

“Conductive Material for a Connecting Part” also concerns a copper-strip base, a copper–tin alloy layer, and a tin covering layer. It specifies layer thicknesses and surface geometry, including limits on the tin layer’s inscribed-circle dimensions and the height difference between the outer surface and the alloy layer. A bright or semi-bright tin electroplating layer forms the outermost surface.
