Latest Patents

Tonouchi's latest patents focus on innovative methods for manufacturing polarizing plastic lenses. One of his patents describes a method that involves a reversing step, where a convex surface shape is transformed into a concave surface shape by pressing a curved polarizing film. This process is followed by assembling a casting mold that positions the reversed polarizing film, along with an upper mold, a lower mold, and a sealing member. The final steps include casting a curable composition into the mold cavity and polymerizing it to create a polarizing plastic lens.

Another patent outlines a similar method, detailing an upper mold positioning step, an adhesive column forming step, and a bonding process between the upper mold and the polarizing film. This method also includes a curing treatment for the adhesive columns and the assembly of a casting mold that sandwiches the polarizing film. The polymerizing and curing step ultimately results in a high-quality polarizing plastic lens.
