Introduction

Akira Ohzu is a prominent inventor based in Ibaraki, Japan, known for his significant contributions to neutron detection technology. With a total of five patents to his name, Ohzu has made remarkable advancements in the field, particularly in the development of innovative detection apparatuses.

Latest Patents

Ohzu's latest patents include a neutron detector and a neutron image detector with scintillator technology. This neutron detector is designed without helium gas and features a translucent type plate neutron scintillator capable of emitting fluorescence from both sides. The scintillator is composed of a zinc sulfide fluorescent substance and a neutron converter containing lithium or boron, arranged at a 45-degree angle to the incident neutrons. The design is housed within a cylindrical detector with a circular or square section, incorporating a specular reflector with a reflectance of 90% or more. The fluorescence emitted upon neutron interaction is detected by two photomultipliers positioned on either side, with the signals processed to yield a neutron signal.

Another notable patent involves a method for detecting fine particles in fluid using X-ray technology. This detection apparatus includes a flow cell for fluid passage, an X-ray source that irradiates the flow cell, and an X-ray detector that measures the intensity of transmission X-rays attenuated by fine particles. Additionally, a fluorescent X-ray detector captures fluorescent X-rays emitted by the particles. A data processing device discriminates between fine particles and air bubbles based on fluctuations in the intensity of the transmission and fluorescent X-rays, allowing for the calculation of the number and diameter of the fine particles.
