With a total of four patents to his name, Sugaya has made significant strides in developing methods that improve the functionality and longevity of plumbing components.

Latest Patents

Sugaya's latest patents focus on preventing the elution of copper and zinc from copper-alloy-made plumbing instruments, which include valves and pipe joints. One of his standout inventions is a method designed to suppress the elution of these metals while utilizing the copper alloy in its original state, which consists of bronze and brass. This innovative method involves forming a protective film on the liquid-contact portions of plumbing instruments using an organic substance composed of unsaturated fatty acids. This film effectively coats both copper and zinc in the surface layer, thereby minimizing elution.

Another significant patent describes a plumbing device made of copper alloy containing nickel salt. This invention details the treatment method for reducing the elution of lead, where the valve and tube coupling are subjected to a washing process using a cleaning fluid containing nitric and hydrochloric acids. The effective combination of temperature and cleaning fluid concentration allows for optimal nickel salt-removal treatment and results in the formation of a protective coating on the liquid-contacting part.
