Jun Okawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of laminate technology and seismic response control. With a total of 2 patents, his work reflects a commitment to advancing engineering solutions.

Latest Patents

Okawa's latest patents include a process for producing laminate and a seismic response controlled frame of bending deformation control type. The laminate patent describes a structure that contains a transparent substrate, a unit layer formed on the substrate, and a tin zinc oxide layer. The unit layer consists of a dielectric layer, a metal layer, a barrier layer, and another dielectric layer, all arranged in a specific order. Notably, the dielectric layers contain substantially no carbon, while the tin zinc oxide layer includes an oxide of tin and zinc as the main component, with carbon present in an amount of at least 0.1 atomic % relative to the total amount of tin and zinc. The seismic response control patent outlines a controlled frame member designed to damp seismic forces in multi-storied buildings. It features a vertical wall column connected to a horizontal wall girder, with a second wall column aligned beneath the girder. This innovative design generates a damping force when the two components are displaced relative to each other, enhancing the building's resilience against seismic deformation.
