Title: Norio Yoshizumi: Innovator in Power Supply Circuits

Introduction

Norio Yoshizumi is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of power supply circuits, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

Yoshizumi's latest patents include a step-up power supply circuit and an integrated circuit device. The step-up power supply circuit features a rectifying diode to which a predetermined voltage Vcc is applied from a power supply. It includes a capacitor connected in series with the rectifying diode, and a trapezoidal wave signal produced by a triangular wave generating circuit is applied to the capacitor to control the rectifying diodes. This design allows for the production of a voltage substantially equal to Vcc and a step-up voltage HVcc that is approximately two times higher than Vcc. The integrated circuit device similarly utilizes a step-up power supply circuit to enhance the performance of amplifiers by automatically adjusting their amplification factors based on the produced step-up voltage.
