Patent number: 11685597Abstract: A bag material has a tubular shape and can be folded back at an intermediate position in a longitudinal direction. Crushed stones can be stored in a folded part of the back material. An opening on one side of the bag material can be moved to a position close to an opening on the other side of the bag material. A one-side closing rope that closes the opening on the one side of the bag material is provided near this opening. An other-side closing rope that closes the opening on the other side of the bag material is provided near this opening. The other of the one-side closing rope and the other-side closing ropes can be released with the opening closed by one closing rope.Type: GrantFiled: July 31, 2018Date of Patent: June 27, 2023Assignees: KYOWA CO., LTD., SUMITOMO CORPORATIONInventors: Koji Kajiwara, Hironori Kawamura, Yoshihiro Ogawa, Shigeru Matsuo

Patent number: 10023360Abstract: The present invention aims at dissolving hydrogen gas in a liquid and maintaining the solubility of the hydrogen gas in the liquid at a high state. A sealing bag 1 that dissolves hydrogen gas in a liquid by being put into the liquid includes a hydrogen permeable film that can permeate hydrogen gas that is sealed and filled in the sealing bag to outside. By sinking this sealing bag 1 into the liquid in advance, the hydrogen gas that is permeated through the hydrogen permeable film is dissolved in the liquid. Furthermore, since the hydrogen gas is continuously permeated little by little through the hydrogen permeable film, the solubility of the hydrogen in the liquid can be maintained at a high state.Type: GrantFiled: March 18, 2013Date of Patent: July 17, 2018Assignees: Hirakimirai Co. Ltd., Kyowa Co. Ltd.Inventors: Wen Shih Chang, Naoyuki Yada

Patent number: 9228569Abstract: The condition of a seabed 200 and the condition of tidal currents near the seabed 200 are investigated in advance to examine the number of filter units (FUs) 50 and the position where the FUs 50 are to be installed. Then, piles 12b as a base of a foundation are provided so as to be supported by a bearing layer. A plurality of FUs 50 are installed in close contact with each other between the seabed 200 and each pile 12b. Then, a formwork 12e for a base slab portion 12a is installed on the upper ends of the piles 12b. Concrete is placed in the formwork 12e to form the base slab portion 12a. Then, a tower 11 is fixed to the upper end of the base slab portion 12a.Type: GrantFiled: December 28, 2010Date of Patent: January 5, 2016Assignees: KYOWA CO., LTD., SUMITOMO CORPORATIONInventors: Takahito Ohkubo, Toshihiro Tanaka, Nobuyoshi Oike, Hironori Kawamura, Shinichi Tanaka, Ikuo Moriyama, Motoo Yoshioka

Patent number: 8657529Abstract: At a location where unevenness 1000 is present, the condition of a seabed 200 is investigated in advance to examine the respective numbers of large filter units 51 and small filter units 52 to be used, and the position where the large filter units 51 and the small filter units 52 are to be installed. Based on the investigation result, the small filter units 52 are installed on the bottom of the unevenness 1000. The large filter units 51 are installed on the upper surface formed by the installed small filter units 52, and are leveled so that the upper surface formed by the installed large filter units 51 becomes flush with the seabed 200.Type: GrantFiled: January 30, 2013Date of Patent: February 25, 2014Assignees: Kyowa Co., Ltd., Sumitomo CorporationInventors: Takahito Ohkubo, Toshihiro Tanaka, Nobuyoshi Oike, Hironori Kawamura, Shinichi Tanaka, Ikuo Moriyama, Motoo Yoshioka
