Title: The Innovative Contributions of Makoto Kanbe

Introduction

Makoto Kanbe is a notable inventor based in Fussa, Japan. He has made significant contributions to the field of industrial X-ray technology. With a total of 2 patents, his work has advanced the capabilities of X-ray tubes and generators.

Latest Patents

One of Kanbe's latest patents is the Industrial X-ray tube. This invention features a cathode and anode housed within a container that has an evacuated interior. Electrons emitted from the cathode strike the anode, resulting in the emission of X-rays. The cathode is constructed from graphite, which is a layered crystal formed by stacking multiple carbon hexagonal planes. The graphite is precisely cut based on the crystal axes of these planes, allowing the cut surface to function as an electron-emitting surface. The cutting can be done along surfaces parallel or orthogonal to the c-axis, enhancing the efficiency of the electron emission.

Another significant patent is the Industrial X-ray generator. This generator includes a booster circuit that connects multiple boosting steps from a low-voltage terminal to a high-voltage terminal. The booster circuit is strategically arranged in the lateral region of the X-ray tube, linking the low-voltage terminal to the anode and the high-voltage terminal to the cathode. A lead wire extends from the cathode to the outside of the X-ray tube, connecting to the high-voltage terminal of the booster circuit. Additionally, a molded member containing insulating resin is designed to shield the cathode side end part of the X-ray tube and the lead wire.
