Title: The Innovative Contributions of Nobuyoshi Kozawa

Introduction

Nobuyoshi Kozawa, an accomplished inventor based in Kariya, Japan, has made significant strides in the automotive industry with two noteworthy patents. His inventions focus on enhancing engine cooling systems, showcasing his dedication to innovation and technology.

Latest Patents

Kozawa's latest patents include a groundbreaking engine cooler and a novel fan assembly for vehicles. The engine cooler is a cylindrically-shaped device designed for automobiles, consisting of a pair of water tanks or main coolant tubes, a multitude of connecting water tubes, cooling fins, and at least one cooling fan. Its unique design positions the cooler so that its axis aligns perpendicularly to the vehicle's traveling line, minimizing air resistance during operation. Moreover, the water tanks can serve a dual purpose as shrouds for the cooling fan, which can be annularly shaped and placed at both ends of the radiator. The design even allows for the use of two cooling fans with varying air-blowing capacities, optimizing the cooling efficiency.

Kozawa's second patent, the fan assembly for vehicles, innovatively utilizes plastic material to create a robust assembly composed of multiple fan blades and a central boss. This assembly is connected to a viscous fluid coupling device that is rotatably mounted on the vehicle's driving shaft. A unique feature of this invention is the inclusion of an axially resilient connecting member in the form of a plate spring, which protects the bearing assembly from potential damage caused by misalignment with the driving shaft. Additionally, he also explored alternative designs, such as incorporating helical or waved springs into the setup.
