Title: Innovations by Shoichi Sato
Introduction
Shoichi Sato is a notable inventor based in Miyagi, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced alloys for eyeglass frames. With a total of 2 patents, Sato's work focuses on enhancing the comfort and functionality of eyewear.
Latest Patents
One of Sato's latest patents is for an eyeglass frame that incorporates a Ti-Ni-V alloy element designed to improve wear and comfort. This eyeglass frame consists of a pair of lens-fixing rims, a bridge connecting the rims, and a pair of temples. The bridge and/or temples are made from a Ti-Ni-V alloy that exhibits super elasticity within a temperature range of 0°C to 20°C. The alloy comprises nickel and titanium in an atomic ratio of 1.02-1.06, along with vanadium at 0.25-2.0 atomic percent. The material is shaped and heat-treated at temperatures between 425°C and 525°C for 10 to 60 minutes to achieve the desired properties.
Another significant patent by Sato involves a shape memory alloy that consists of vanadium at 0.25-2.0% and the balance of nickel and titanium. The atomic ratio of nickel to titanium in this alloy ranges from 0.96 to 1.06. This shape memory alloy is characterized by good workability and a reduced temperature difference between the martensitic transition start point and the austenitic transition finish point. Depending on the atomic ratio of nickel to titanium, the martensitic transition start point can be at room temperature or higher, or at room temperature or lower, providing pseudo elasticity.
