Title: **Masakazu Mitamura: Innovator in Current Sources and A-D Conversion Technologies**

Introduction

Masakazu Mitamura, an accomplished inventor based in Gyoda, Japan, has made significant contributions to the field of electrical engineering with three registered patents to his name. His innovative work focuses primarily on advancements in current sources and analog-to-digital (A-D) conversion systems.

Latest Patents

Among his notable patents, Mitamura has developed a **Variable Current Source**, which utilizes multiple metal resistance elements and a dedicated compensation resistance element on a single substrate. These components operate under identical temperature conditions to maintain accuracy. By applying a reference current to the compensation element, an auxiliary reference voltage is generated. This design includes a series of switches linked to reference elements that allow for selective control, enabling the generation of diverse current outputs.

His second major innovation is the **Dual Slope System A-D Converter**. In this system, a digital value is established through setting means that feeds into switch drive signal generating means, producing a switch drive signal that corresponds to this digital value. This signal activates a switch that allows a constant voltage to be superimposed on an analog input voltage, ultimately enhancing the efficiency of the A-D conversion process.
