  • Publication number: 20240363911
    Abstract: An energy storage apparatus 50 includes an energy storage cell 62, a current interruption device 53 that interrupts a current I to the energy storage cell 62 and a control unit 121. The control unit 121 interrupts a current by opening the current interruption device 53 in a case where abnormality of the energy storage apparatus 50 is detected together with a vehicle crash, and resumes the supply of electricity to a vehicle, which has been crashed, by closing the current interruption device 53 in a case where the abnormality is no longer detected.

  • Publication number: 20060213094
    Abstract: Seam puckering on a sewn product made of cellulosic fibers, synthetic fibers and/or animal fibers can be prevented from occurring by simply applying a (meth)acrylate resin finish and/or a polyester resin finish to the seams on the sewn product, then hot pressing the seam. The addition of an acidic catalyst, a polyether compound, or a combination of a cellulose-reactive resin finish with an acidic catalyst to the (meth)acrylate finish and/or polyester resin finish provides a better seam pucker preventing effect on cellulosic fibers than do existing cellulose-reactive resin finishes.
