  • Method of detecting defects of a structure
    Patent number: 5816703
    Abstract: A method of detecting a defect on the surface of a structure using an infrared radiometric thermometer. It is determined that there is a lifting defect at a region of the surface if the region has a temperature difference of 0.3.degree. C. or more in comparison with a surrounding region and has an area of 200 cm.sup.2 or more. The temperature of the surface of the structure is obtained using the infrared radiometric thermometer in a period of time from 19:00 p.m. on a day when it is clear at least in the daytime to 4:30 a.m. on the next day.

  • Water-soluble radical-curing polyvinyl alcohol derivative
    Patent number: 5200464
    Abstract: A radical-curing polyvinyl alcohol derivative is disclosed, which is obtained by reacting an anion-modified polyvinyl alcohol prepared by saponification of a copolymer comprising vinyl acetate and an unsaturated carboxylic acid and/or a derivative thereof with a glycidyl-containing vinyl compound in water or in a mixed solvent of water and a lower alcohol under acidic conditions, and which is useful as an image-forming material which is curable upon light irradiation and developable with water.
