**Title: Innovations of Tatsuya Saito: A Pioneer in Transmission Technologies**

Introduction

Tatsuya Saito, an accomplished inventor based in Gotemba, Japan, has made significant contributions to the field of automotive engineering with five notable patents to his name. His innovative designs focus on enhancing the efficiency and performance of power transmission systems in vehicles, reflecting his extensive expertise in this vital area of technology.

Latest Patents

Among Tatsuya Saito's recent patents is a groundbreaking **lubrication system for a power transmission unit**. This system is designed to supply oil to a starting clutch efficiently regardless of its engagement state. When the friction clutch is fully engaged or disengaged, the first control valve operates in a low inflow rate mode, while the second control valve functions in a low outflow rate mode. In contrast, when there is slipping with the engaged friction clutch, both valves switch to high inflow and high outflow rate modes, ensuring optimal lubrication and performance.

Another significant invention is the **variable transmission system for vehicles**. This system enables better control over a chain belt by pressing a chord portion when a hydraulic pressure detected by a sensor reaches a predetermined value or more. This design helps prevent the chain belt from disengaging from a sheave, particularly at low vehicle speeds, without compromising fuel efficiency or driving torque.
