Title: Naoji Akutsu: Innovator in Fixing Unit Technology

Introduction

Naoji Akutsu is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of fixing unit technology, holding a total of 17 patents. His innovative designs have advanced the efficiency and safety of heating mechanisms used in various applications.

Latest Patents

One of Akutsu's latest patents involves a fixing unit that effectively fixes a developing material deposited on a recording medium by heating and pressing the medium. This fixing unit comprises two heating members that apply heat to the recording medium, along with two temperature-sensitive shutoff devices connected in series with each heating member. Each shutoff device includes a first and a second heat-sensitive shutoff element. The first element cuts off electric power to the heating member when its surface temperature exceeds a certain threshold. Similarly, the second element performs the same function for the other heating member. Another patent describes a fixing unit that utilizes a first number of heating members and a second number of switches to supply electric power. Each switch responds to the surface temperature of its corresponding heating member, ensuring that electric power is shut off when the temperature exceeds a predetermined value.
