Title: Kenji Otsu: Innovator in Machine Tool Technology

Introduction

Kenji Otsu is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of machine tool technology, holding a total of nine patents. His work focuses on enhancing the efficiency and accuracy of machine tools through innovative systems and methods.

Latest Patents

One of Kenji Otsu's latest patents is a machine-tool-state determination system and method. This system is designed to determine the state associated with a machine tool that includes a rotation mechanism for processing a member. The system comprises a sensor that acquires state values from the machine tool and an analysis device that performs spectral analysis on the time series data of the state value. This analysis extracts the rotational frequency of the rotation mechanism and identifies harmonic waves related to that frequency. The analysis device calculates the ratio of the amplitude of the rotational frequency to that of the harmonic wave, generating feature-amount data that includes the state value and the ratio as feature amounts. The device then performs clustering with this data to determine the machine tool's state based on the clustering results.

Another aspect of his innovation involves a sensor that includes a first film, a first sensor portion, a driving portion, and a processor. The first sensor portion is equipped with a first magnetic layer, a second magnetic layer, and a first intermediate layer. The driving portion is responsible for causing the first film to deform at a specific frequency, while the processor outputs a third signal based on the first and second signals.
