Title: Ryoji Negi: Innovator in Track Displacement Measurement Technology

Introduction

Ryoji Negi is a prominent inventor based in Kobe, Japan. He has made significant contributions to the field of track displacement measurement technology. With a total of 5 patents to his name, Negi's work has advanced the understanding and functionality of rail systems.

Latest Patents

Negi's latest patents include a track displacement measurement device, a track displacement measurement system, and a track displacement measurement method. The track displacement measurement device is designed to measure the displacement of the track on which a railroad car runs. It determines the first displacement of the track by performing processing that includes an integration operation based on a motion detection signal responsive to the motion of the railroad car due to track displacement. Additionally, it determines the second displacement of the track based on a rotational movement detection signal responsive to the railroad car's rotational movement. The combined displacement of the track is then calculated based on both the first and second displacements.

Another notable invention is the railcar, which features an underframe that includes a pair of side sills located at both ends of the underframe in a car width direction. These side sills extend in a car longitudinal direction and are coupled by a plurality of cross beams. The underfloor cover of the railcar is made of stainless steel and consists of upper and lower plate-shaped members that are at least partially spaced apart from each other.
