  • Publication number: 20200353442
    Abstract: Provided is a water-absorbent resin which is capable of giving an absorbent material improved gel-shape stability and which has excellent water-absorption capacity. A water-absorbent resin of the present invention is a polymer of a water-soluble ethylenically unsaturated monomer, and has the following properties (1) and (2): (1) A disintegration amount at 20-fold swelling is 30% by mass or less; and (2) a solubility in physiological saline is 25% by mass or less. (Determination Method for Disintegration Amount at 20-Fold Swelling) 5 g of the water-absorbent resin is added to 100 g of physiological saline to allow the water-absorbent resin to absorb the physiological saline, thereby obtaining a gel. The obtained gel is divided approximately equally into five portions, and these portions are introduced respectively into cylindrical molds having a length of 3.6 cm and a radius of 2.8 cm and molded. The masses of the five molded cylindrical gels are measured.

  • Publication number: 20200213519
    Abstract: A predetermined image processing is carried out on the images that have been taken by the cameras 101 through 108 attached to a side of the cars that form a train before the images are displayed on the monitor 301 that is mounted in the train. That is to say, as a first image processing, among the images to be displayed, a left-right inversion process is carried out on the images where the positional relationship between the cars and the platform in the image is opposite between left and right to the positional relationship as viewed in the direction in which the train is to travel. In addition, as a second image processing, a cutout process is carried out on the images to be displayed so that the cutout regions differ in accordance with the opening and closing state of the doors.
