Title: The Innovative Contributions of Makoto Tsunashima

Introduction

Makoto Tsunashima is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of engineering, particularly in the development of advanced systems for printing machinery. With a total of four patents to his name, Tsunashima's work has had a considerable impact on the efficiency and functionality of folding machines and rotary presses.

Latest Patents

One of Tsunashima's latest patents is a paper jam detection system for folding machines. This system includes an interval signal generator that alternates between ON and OFF levels according to the cutting intervals of a cutting cylinder. It also features a signature detection mechanism with reflection plates and a photoelectric sensor that generates a detection signal upon identifying the reflection plate. The control unit then outputs a paper jam signal based on the interval signal and the detection signal.

Another significant patent is a synchronous control system for rotary presses. This system aims to perform synchronous control of driving means with high precision, quickly stabilize rotation, and reduce spoilage caused by phase shifts. It comprises multiple printing mechanisms where driving means rotate while plate cylinders complete one turn. The control section replaces the rotational phase of the plate cylinder with that of the driving means to ensure that printing images are matched with a predetermined reference.
