Title: The Innovative Contributions of Makoto Noda

Introduction

Makoto Noda is a notable inventor based in Gifu, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced lighting and transformer technologies. With a total of two patents to his name, Noda's work reflects a commitment to innovation and safety in electrical systems.

Latest Patents

Noda's latest patents include a sign lamp lighting transformer with protective functions. This invention features an abnormality detection circuit that identifies issues related to ground faults in the secondary winding circuitry of the transformer. It also detects non-grounding faults of the transformer assembly casing and false connections of the AC power source in reverse polarity. An interrupter circuit is designed to turn off a switch in response to any detected abnormalities, thereby interrupting the AC power supply to the transformer. When the power supply is interrupted, the switch connects to a restart circuit, allowing a charging current to flow to a capacitor. This capacitor is connected in series within a drive current path of a drive circuit, with a time delay of approximately 0.5 to 1.0 seconds determined by a delay circuit.

Another significant patent is the high-frequency power unit for neon tubes. In this invention, DC power is converted by an inverter into high-frequency power, which is then supplied to the primary winding of a neon transformer. One or more neon tubes are connected in series across the secondary winding of the transformer. A saturable reactor is also connected across the secondary winding, which has the characteristic of saturating its magnetic flux when the output voltage from the transformer increases to 1.1 to 2.0 times the rated voltage.
