Title: Takeo Kitazawa: Innovator in Electronic Circuits

Introduction

Takeo Kitazawa is a notable inventor based in Azumino, Japan. He has made significant contributions to the field of electronic circuits, holding a total of 5 patents. His work focuses on enhancing the functionality and efficiency of electronic devices.

Latest Patents

One of Kitazawa's latest patents is for a level shifter and electronic apparatus. This invention connects a first circuit and a second circuit, which operate at different voltages, through a level shifter. The combination circuit within the level shifter utilizes an enable signal that switches between active and inactive states based on the potential supplied to a second high potential power line. When the enable signal is active, the combination circuit outputs a first signal and a logically inverted second signal to a level shift circuit. Conversely, when the enable signal is inactive, both signals are maintained at a low level.

Another significant patent involves a power source control circuit, portable information processing device, and power source control method. This circuit includes a USB power supply that delivers electric power from a power source circuit to a secondary battery, alongside a solar power supply portion and a monitoring circuit. The monitoring circuit halts the electric power supply to the secondary battery if power is being supplied from the power source circuit. This innovation allows for efficient charging of the secondary battery from a stable power source while also utilizing solar energy.
