Title: **The Innovative Contributions of Kozo Shibukawa**

Introduction

Kozo Shibukawa, based in Kawasaki, Japan, is an accomplished inventor known for his innovative designs and contributions to the field of precision measurement tools. With a total of two patents to his name, Shibukawa's work exemplifies a commitment to enhancing the accuracy and efficiency of measurement instruments.

Latest Patents

Shibukawa's latest patented inventions include the two-leg vernier calipers and its manufacturing method. These two-leg vernier calipers are characterized by a main beam assembly composed of two parallel legs, with a vernier assembly supported on the main beam. The design of separate measuring jaws for both the main beam and the vernier allows for versatility and standardization. Each measuring jaw can be selected based on the type of instrument being assembled, enabling the main beam and vernier assemblies to be constructed from different materials. This invention also streamlines the manufacturing process by fixing the measuring jaws at right angles to the two legs of the main beam and the vernier, eliminating the need for additional calibration of the measuring surfaces post-assembly.

Moreover, Shibukawa's vernier caliper features a main beam body made of two round rods, which are parallel and connected at one end by a jaw and at the other by a rear frame. The vernier is supported in such a way that it can move freely along the rods. The hollow design of the rods allows their ends to be securely fitted into the jaw and rear frame using adhesives, solder, or screws. This innovative structure ensures accurate measurements without the need for grinding the jaw faces after assembly.
