  • Bis(fluorosulfonyl) imide metal salt and method for preparing same
    Patent number: 11097949
    Abstract: In the present invention, a bis (fluorosulfonyl) imide metal salt is an alkali metal salt of bis (fluorosulfonyl) imide or an alkaline earth metal salt of bis (fluorosulfonyl) imide. The bis (fluorosulfonyl) imide metal salt has an average particle diameter of not less than 0.1 mm, or has an average moisture absorption rate of not more than 2.5 mass ppm/cm2·min when sealed in a PE bag having a thickness of 80 ?m and left for 30 minutes at 23° C. and 65% humidity.
    Type: Grant

  • METHOD FOR PRODUCING BIS(FLUOROSULFONYL)IMIDE ALKALI METAL SALT AND BIS(FLUOROSULFONYL)IMIDE ALKALI METAL SALT COMPOSITION
    Publication number: 20190152792
    Abstract: The present invention provides a method for producing a bis (fluorosulfonyl) imide alkali metal salt by a reaction of a mixture containing bis (fluorosulfonyl) imide and an alkali metal compound is provided. According to this method for producing a bis (fluorosulfonyl) imide alkali metal salt, a total of weight ratios of the bis (fluorosulfonyl) imide, the alkali metal compound and the bis (fluorosulfonyl) imide alkali metal salt to an entire reacted mixture is not less than 0.8, after the reaction.

  • Vehicular seat support structure
    Patent number: 6435589
    Abstract: The vehicular seat support mechanism includes a vehicular seat having a seat cushion that forms a sitting portion, the seat cushion having a pivot axis, which is horizontal with respect to the width direction of a vehicle, provided toward the rear thereof, which enables the seat cushion to pivot in a fore-and-aft direction of a vehicle, and a link mechanism that moves the pivot axis of the seat cushion to rear and downward. This support mechanism reduces the height of the pivoting locus of the seat drawn when the seat is placed into storage, thus allowing the seat to be pivoted into storage without requiring a large space.
