Title: Tetsuji Kato: Innovator in Diagnostic Systems

Introduction

Tetsuji Kato is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of diagnostic systems, holding a total of 8 patents. His work focuses on enhancing the reliability and efficiency of failure diagnosis in various equipment.

Latest Patents

One of Kato's latest innovations is a failure diagnosis system that flexibly responds to changes in diagnosis targets. This system utilizes a difference in measurement data before and after maintenance to predict potential failures. It features a pre-maintenance data database that stores measurement data prior to maintenance and a post-maintenance data database for data collected afterward. Additionally, a feature detection algorithm group database is included, which stores multiple feature detection algorithms. The system detects a first feature based on measurement data using these algorithms and selects one based on the detected feature. A second feature is then identified, allowing for the diagnosis of potential failures in the target equipment.

Another notable patent is related to a rotor diagnostic apparatus. This apparatus includes a parameter selection component that calculates evaluation values indicating how much sensor values of a rotor deviate from a reference value. It selects parameters for abnormality diagnosis based on these evaluation values. The diagnosis part outputs an abnormality value that indicates how abnormal the rotor is, based on the distance in a multidimensional space between sensor values in a normal state and those targeted for diagnosis.
