Introduction

Koichi Murai is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of light inspection technology, particularly through his innovative patent. His work has implications for quality control in various industries, especially in film production.

Latest Patents

Murai holds a patent for an "Apparatus and method for inspecting light transmittable material." This invention involves an inspection device that utilizes an inspection light projector and an auxiliary light emitter. These components project light onto a filmstrip, allowing for the detection of defects. The defect detector receives the inspection light after it has passed through the filmstrip and generates a data signal. This signal is then analyzed by a controller, which compares it to a predetermined threshold. If the signal level falls below this threshold, the controller identifies a coloring defect in the filmstrip. Additionally, the presence of dust on the filmstrip can increase the signal level, as the auxiliary light is diffused by the dust.
