News editors obtained the following quote from the background information suppli ed by the inventors: “In steel manufacturers, metallographic inspection is perfo rmed to assure the quality of shipped steel products. In metallographic inspecti on, the inspector uses a microscope to visually inspect a specimen cut out from a steel product to check the type and amount of non-metallic inclusion and grain sizes of the steel. When determining the grain size (grade determination), it i s common to compare the specimen with the standard diagram specified by JIS (Jap anese Industrial Standards) to determine the grain size number.”
