Latest Patents

Fujisawa's latest patents include the "Multi-cell gas-filled bag and method for producing the same" and the "Abrasion resisting flexible joint pipe." The multi-cell gas-filled bag is designed for use as a dock fender, a connector for lighters, and a float for supporting sand-flash pipes during reclamation. This invention simplifies the production process by uniting inner and outer sleeves made of elastic rubber, each containing embedded reinforcing material. Gas is introduced into non-adhering portions between the sleeves, creating cavities filled with gas through the deformation of the inner sleeve.

The abrasion resisting flexible joint pipe is engineered to flexibly connect opposed end tubes made of rigid material while transferring mud or sand during dredging operations. This invention features a pair of opposed end tubes, an elastic rubber body that holds the tubes together, and a spherical shell-shaped reinforcing layer embedded within the rubber body. This design enhances durability and flexibility, making it suitable for challenging environments.
