Title: Koji Ueda: Innovator in High-Frequency Heating Technology

Introduction

Koji Ueda is a notable inventor based in Minoo, Japan. He has made significant contributions to the field of high-frequency heating technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of heating apparatuses.

Latest Patents

Ueda's latest patents include a high-frequency heating apparatus with a displacement identifiable remaining heating duration and phase control based thereon. This innovative device utilizes a microcomputer to input the phase signal of a commercial AC power supply. It determines whether a timer switch in a mechanical timer apparatus is in the ON-state, indicating that the heating apparatus is in a heating-time set state. The microcomputer then activates a switch that controls the conduction between the commercial AC power supply and a high voltage transformer, minimizing rush current and allowing users to visually confirm the remaining heating time, ultimately leading to cost reduction.

Another significant patent by Ueda is a high-frequency heating apparatus designed to maximize input current while securing a uniform margin relative to the cutoff current. This apparatus aims to maximize and efficiently output high-frequency waves. It includes a power supply unit, an input current detector, a power converting unit, an inverter controller, a magnetron, and a circuit for implementing negative feedback control. The control circuit, equipped with a microcomputer, outputs signals to the inverter controller to control the input current, ensuring that the input current characteristic approximates the current cutoff characteristic of the overcurrent circuit breaker with respect to elapsed time.
