Title: **The Innovative Mind of Yoshitomo Kouno: A Glimpse into His Patents**

Introduction

Yoshitomo Kouno, an accomplished inventor based in Saitama, Japan, has made significant contributions to the field of engineering with his innovative solutions. With a total of four patents registered to his name, Kouno's work primarily focuses on the development of advanced controllers and actuators, particularly for use in internal combustion engines.

Latest Patents

Among Kouno’s latest patents is a groundbreaking **Controller for Controlling an Electromagnetic Actuator**. This device comprises a pair of springs working in opposing directions and an armature connected to the springs. When not activated, the armature is held in a neutral position by the springs. The actuator features a pair of electromagnets that drive the armature between two end positions. When the armature is released from one of the end positions, the controller applies a brake based on the load condition, ensuring high-load conditions allow the valve to open without extra electrical power. In low-load situations, the armature is prevented from colliding with the yoke of the electromagnet.

Furthermore, Kouno developed a **Solenoid-Type Valve Actuator for Internal Combustion Engine**, which boasts a straightforward yet effective construction capable of maintaining stable valve operation while minimizing sliding resistance. This actuator uses two electromagnets positioned opposite one another, allowing an armature to reciprocate and control valve movements with reduced power consumption and better responsiveness.
