Title: Jun Shindo: Golf Ball Materials and Performance

Introduction

Jun Shindo is an inventor based in Chichibu, Japan, whose patent work focuses on golf ball materials and performance. He is associated with Bridgestone Sports Co., Ltd. and has 3 patents.

Latest Patents

Shindo’s listed patents include “Rubber Composition for Golf Ball” and “Golf Ball.” Both describe rubber compositions and core designs intended to improve golf ball flight while maintaining durability.

“Rubber Composition for Golf Ball” concerns a base rubber combined with a co-crosslinking agent, an organic peroxide, and a moisture-providing agent. The composition is designed to create a substantial hardness difference within the golf ball core, helping reduce spin on shots and improve flight performance while enhancing resistance to cracking.

“Golf Ball” describes a ball with a core molded from a rubber composition containing water, alongside a cover made of one or more layers. The core’s formulation and specified hardness and deformation characteristics are intended to produce low-spin performance and improved flight while retaining durability against impact.

Career Highlights

Shindo’s disclosed inventions address the relationship between core composition, internal hardness, spin, flight, and durability. His work reflects a materials-engineering approach to improving golf ball performance.

Collaborations

Shindo is associated with Bridgestone Sports Co., Ltd., a company whose golf equipment work provides the context for his golf ball inventions.

Conclusion

Jun Shindo’s patents focus on rubber compositions and core structures designed to balance low-spin flight performance with durability in golf balls.
