Title: **Innovations by Michiaki Igarashi: A Pioneer in Hydraulic Technology**

Introduction

Michiaki Igarashi, an inventive mind based in Yokosuka, Japan, has made significant contributions to the field of hydraulic machinery. With a total of three patents to his name, Igarashi focuses on enhancing the efficiency and functionality of civil engineering equipment. His innovative designs reflect a commitment to improving operational performance and reducing unnecessary resource consumption.

Latest Patents

Igarashi's latest patents showcase his expertise in hydraulic control systems. One of his notable inventions is a **control system for hydraulic pumps in civil machinery**. This innovative system allows for a flow-rate controller to apply a preset signal instead of the typical flow-rate signal when the hydraulic pump's delivery pressure exceeds a predetermined threshold. By enabling a minimum flow rate to maintain the working tool in a specific posture, this system reduces pressure loss and temperature rise in hydraulic oil, ultimately improving the fuel consumption and cycle time of the machinery.

Another significant patent is his design for a **semi-automatic hydraulic excavator**. This excavator is equipped with automatic control features that manage the arm and bucket angles, facilitating a swift return to the original excavation posture after dumping the excavated soil. With arm and bucket angle detectors in place, deviations between the detected values and preset values are minimized through a feedback control mechanism. This innovation enhances the ease of operation, allowing for effective excavation with less skill required from the operator.
