  • Powder paint compositions
    Patent number: 6084009
    Abstract: A thermosetting powder paint composition comprising:(A) a (meth)acrylic copolymer having glycidyl groups;(B) a polybasic carboxylic acid and/or polybasic carboxylic anhydride; and(C) particles having a core/shell structure each comprising a core having Tg of 20.degree. C. or below, the core being covered at least partially with a shell having Tg of 40.degree. C. or above, and said shell having no glycidyl group.The paint composition is excellent in weather resistance as well as in impact resistance and chipping resistance.

  • Process for the separation of radioactive iodine compounds by precipitation
    Patent number: 5352367
    Abstract: A process for the separation of radioactive iodine compounds by precipitation is provided. This process comprises adding 0.1 to 3 parts by weight of a reducing agent and an effective amount of silver nitrate to 100 parts by weight of a liquid waste containing radioactive iodine compounds while keeping the liquid waste at a temperature ranging from 20.degree. to 80.degree.C., and stirring the obtained mixture for 0.5 to 72 hours to precipitate the radioactive iodine compounds. Silver nitrate is preferably used in a molar concentration which is 1 to 4 times that of radioactive iodine molecules contained in the liquid waste. By this process, iodates which could not be precipitated by conventional methods can be effectively precipitated and separated to thereby reduce the amount of radioactive iodine discharged to the environment.

  • Temperature history indicator and its manufacturing method
    Patent number: 4931420
    Abstract: A temperature history indicator and its manufacturing method wherein the indicators are formed as chips, labels, tags or the like and accompanied with those goods or their packings which must be stored at a certain temperature or lower and when their storage temperature rises higher than the certain temperature over a not-permissible time period, this fact can be visibly shown by development or change of color caused by chemical matters in the indicator, characterized in that when temperature rises higher than a certain value, a hydrophobic organic compound enclosed in microcapsules melts and diffuses causing a dye-precursor and a color developer, which are prepared independently of the compound, to be contacted with each other to irreversibly achieve color development or change, that this color development or change system is rendered operative when the temperature rise continues to exceed a permissible time period, and that when the tops of the color development or change systems are coated with a transpare
