Title: Susumu Harashima: Innovator in Structural Defect Detection and Image-Forming Materials
Introduction
Susumu Harashima is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the fields of structural engineering and material science. With a total of 2 patents, Harashima's work focuses on innovative methods for detecting structural defects and developing advanced materials.
Latest Patents
One of Harashima's latest patents is a method of detecting defects in a structure. This method utilizes an infrared radiometric thermometer to identify surface defects. It is determined that a lifting defect exists in a region if there is a temperature difference of 0.3 degrees Celsius or more compared to the surrounding area, with an area of 200 cm² or more. The temperature readings are taken during a specific time frame, from 19:00 p.m. on a clear day to 4:30 a.m. the following day.
Another significant patent is for a water-soluble radical-curing polyvinyl alcohol derivative. This innovative material is created by reacting an anion-modified polyvinyl alcohol with a glycidyl-containing vinyl compound in water or a mixed solvent under acidic conditions. This derivative is particularly useful as an image-forming material that can be cured upon light irradiation and is developable with water.
