Title: Masatoshi Morikawa: Patents in Construction Machinery

Introduction

Masatoshi Morikawa is an inventor associated with Hitachi Construction Machinery and based in Ushiku, Japan. His patent work addresses practical systems for work machines and construction equipment. He is credited with 2 patents.

Latest Patents

Morikawa’s listed patents include two inventions related to construction machinery.

- **Work machine.** This invention describes a controller that uses operator input to determine the target position of a plane marking an entry-prohibited area. The controller checks whether the target position is farther from the upper structure’s swing center than a threshold based on the structure’s rear-end distance. If the condition is met, the controller accepts the target position and sets the prohibited-area plane there.

- **Construction machine.** This invention concerns antenna storage and retention on a hydraulic excavator’s upper revolving structure. Antennas can be removed from their mounting tools while their cables remain connected, then retained in designated rooms. A housing cover with lockable doors closes those rooms.

Career Highlights

Morikawa’s listed inventions focus on equipment operation and component management in construction machinery. The work-machine patent describes a control feature for setting an entry-prohibited area, while the construction-machine patent addresses the secure storage of antenna devices.
