  • Net fabric to be processed into net product
    Patent number: 6670018
    Abstract: A net fabric to be processed into a net product capable of simplifying processing during manufacturing of a net product, leading to a reduction in manufacturing cost of the net product is disclosed. The net fabric is so constructed that the side edge portions of the net fabric, which are subjected to processing such as cutting, vibrational welding or the like, have a higher compressibility in the thickness direction than the middle portions of the net fabric. This ensures that the net fabric exhibits a better workability during the manufacturing of the net product using the net fabric in order to simplify the manufacturing process, and to lead to a reduction in manufacturing cost, even though the net fabric has a three-dimensional structure.
    Type: Grant
    Filed: May 22, 2001
    Date of Patent: December 30, 2003
    Assignees: Delta Tooling Co., Ltd., Suminoe Textile Co., Ltd.
    Inventors: Etsunori Fujita, Yumi Ogura, Masaki Nishino, Eiichi Koyama, Yoshio Tsumura, Kazuhiro Ueda
  • Three-dimension ceramics structure and method for producing the same
    Publication number: 20020068149
    Abstract: A method for manufacturing a three-dimension ceramics structure includes the steps of immersing a three-dimension structural fabric into ceramics slurry, and baking the three-dimension structural fabric raised from the ceramics slurry at a predetermined temperature to eliminate organic components of the three-dimension structural fabric to thereby obtain the three-dimension ceramics structure.
