Title: Innovations by Yuusuke Ishizaki

Introduction

Yuusuke Ishizaki is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of load detection technology, holding a total of 10 patents. His work focuses on developing advanced apparatuses that enhance the accuracy of load abnormality detection.

Latest Patents

One of Yuusuke Ishizaki's latest patents is a load abnormality detection apparatus that performs accurate judgment of the cause of abnormality. This apparatus detects load abnormalities in first and second rotational members acting on each other. It features an inclination calculation part that calculates the inclination of a second control element. A first comparison part compares a first control element with a first threshold value and a second threshold value that is larger than the first. Additionally, a second comparison part assesses the inclination of change in the second control element against a third threshold value of a negative value and a fourth threshold value of a positive value. The abnormality detection part identifies the cause of the detected load abnormality based on the results of these comparisons.

Another notable patent by Ishizaki is also a load abnormality detection apparatus, which includes first and second rotational members that may contact each other directly or through a recording medium. This apparatus is driven by a first motor controlled by a first drive current and a second motor controlled by a second drive current. It incorporates a current detection part to monitor these drive currents, along with judgment parts that assess whether the currents fall within specified ranges. The abnormality detection part then identifies any load abnormalities based on the results from these judgments.
