Title: Tetsuya Obara: Innovating Power Solutions and Sunroof Mechanisms

Introduction

Tetsuya Obara is an accomplished inventor based in Yokohama, Japan. With a focus on improving electrical power supply systems and automotive technologies, he has made significant contributions to the engineering field. His innovative spirit is reflected in his two patents, which showcase his dedication to advancing technology.

Latest Patents

Obara's latest patent is for a power supply apparatus featuring separate plural outputs. This invention utilizes a circuit comprised of a diode and a capacitor linked to a secondary coil of a thin transformer, such as a wire-type transformer. During the reset time of the transformer, excitation energy is discharged and then accumulated in the capacitor, which allows for the generation of direct current output voltages with two outputs through a single transformer. This design emphasizes compactness and lightweight properties, resulting in a thin power supply apparatus. Additionally, by utilizing a small winding ratio for the transformer, copper loss is minimized, leading to reduced manufacturing costs and the elimination of the need for higher switching frequencies.

Another notable patent by Obara is a sunroof driving apparatus. This device incorporates a motor unit with a motor shaft capable of rotating both forward and backward, paired with an output unit designed to convert the rotation into the opening and closing movements of a sunroof lid. Significantly, both the motor and output units are positioned away from the vehicle's roof, enhancing the design and operational efficiency of the apparatus.
