Title: Fujio Ikeda: Innovator in Surge Absorber Technology

Introduction

Fujio Ikeda is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of electronic devices, particularly in surge absorption technology. With a total of six patents to his name, Ikeda's work has had a considerable impact on the industry.

Latest Patents

One of Ikeda's latest patents is a surge absorber that features a Metal Electrode Face Bonding Device (MELF) surge absorbing element. This element can be connected across a pair of input lines of an electronic device. It is secured in electrical contact with the input lines by a conductive heat releasable adhering means, such as solder. A spring is positioned in a biased relationship against the surge absorbing element. When subjected to overvoltages or overcurrents, the surge absorbing element heats up, causing the adhering means to release its securement. This mechanism prevents further heating of the surge absorbing element, ensuring the safety of the electronic device.

Another innovative patent by Ikeda involves a surge absorber that incorporates a thermal response switch. This switch is inserted in an input line at the input side of the surge absorbing element. It includes a conductive spring piece and a conductive hook piece, with at least one of these components made of a thermal response material. Upon stopping the applied continuous overvoltages or overcurrents, the switch can automatically restore itself, depending on the extent of the overcurrent.
