Title: Innovations of Katsuyoshi Nukui

Introduction

Katsuyoshi Nukui is a notable inventor based in Mitaka, Japan. He has made significant contributions to the field of tape drive technology, holding two patents that showcase his innovative approach to solving technical challenges.

Latest Patents

One of his latest patents is the "Tape Drive Control Apparatus." This invention features a tape drive control system where a tape is wound on a capstan that rotates at a constant speed. The system operates by utilizing the friction between the capstan and the tape, eliminating the need for a pinch roller. The tape is designed to move away from the capstan during fast modes, such as fast forward or rewinding, as well as during stop modes. Another significant patent is the "Tape Driving Apparatus." This apparatus ensures that even when the radius of a magnetic medium, like a magnetic tape, varies on a supply or take-up reel, the current flowing in a servo motor coupled directly to the capstan is adjusted according to the load. This innovation allows for a constant speed of the servo motor by controlling a reel motor, thereby equalizing the back tension and take-up tension of the magnetic tape.
