Title: Innovations of Yukihira Nakazato

Introduction

Yukihira Nakazato is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of electrical engineering, holding a total of eight patents. His work primarily focuses on current measuring circuits and temperature detection apparatuses, showcasing his expertise in innovative technologies.

Latest Patents

One of Nakazato's latest patents is a current measuring circuit. This invention includes a first resistor, a second resistor, a transistor, and a third resistor connected in series between a ground potential and an output terminal of a power circuit. Additionally, a current-detecting resistor is inserted in series between a high-voltage site and an output terminal of a power circuit that supplies a predetermined direct voltage to the high-voltage site. A differential amplifier controls the current flowing through the transistor, ensuring that the potential difference generated across the third resistor is proportional to that across the current-detecting resistor. By measuring the voltage at the connection node of the first and second resistors, the current flowing through the high-voltage site can be accurately calculated.

Another significant patent is a temperature detection apparatus. This device features a transformer and a thermostat that is directly attached to an electrically conductive site of the heating element. The thermostat has contacts that either short-circuit or open-circuit based on whether the temperature of the heating element meets a predetermined threshold. The contacts are connected to a secondary coil in the transformer, along with a DC voltage source and a transistor that supplies the necessary AC power to the primary coil. A current detection resistor monitors the current flowing through the primary coil, while a comparison circuit detects the voltage across the current detection resistor. This circuit outputs an alarm signal when the current exceeds a preset threshold.
