Title: **Katsumi Shiono: Innovator in Redundant Disk Array Systems and Laser Cutting Technologies**

Introduction

Katsumi Shiono, an inventive mind hailing from Ako, Japan, has made significant contributions to technology through his six patents. As an employee at Mitsubishi Electric Corporation, he has developed innovative solutions that enhance data processing and materials cutting.

Latest Patents

Shiono's latest patents showcase his expertise in two distinct areas: redundant disk array systems and laser material cutting methodologies. One of his notable inventions is a redundant disk array (RAID) system that utilizes separate cache memories. This system is designed to expedite the data writing process into the redundant disk array by incorporating a first cache memory for access, a second cache for storing outdated data, and a third for storing old control key (CK) data. This innovative arrangement reduces the number of accesses into the disk array during data writing, facilitating quicker processing speeds.

In addition to his work on RAID systems, Shiono has also patented a method for cutting materials using laser beams. This method includes a two-step process: initially cutting the material with a laser and subsequently cleaning the cut surface using water as a solvent. The cleaning may involve ejecting a jet of water or utilizing a water-impregnated cloth, sponge, or paper, ensuring a clean and precise finish.
