Latest Patents

One of Yokoyama's latest patents is an imaging lens unit designed to suppress a reduction in optical performance, even when plastic lenses absorb water. This innovative lens unit includes a lens barrel made of resin and features first to seventh plastic lenses housed within it. Notably, at least two adjacent plastic lenses possess different water absorption rates and conical fitting slopes centered on the optical axis. This design ensures that the fitting slope of a high-water-absorption plastic lens is positioned outside the fitting slope of a low-water-absorption plastic lens, thereby maintaining optical integrity.

Another significant patent involves a shield case and electronic apparatus. This shield case is equipped with a first anchor part for anchoring to a substrate and features a slit extending from a release edge to a top plate. The design of this shield case enhances the functionality and reliability of electronic devices.
