  • Patent number: 8576034
    Abstract: A plug or connector including a coded magnet and an electrical contact. As the plug approaches a corresponding port, the coded magnet interacts with a magnet within the port. The interaction between the plug coded magnet and the port coded magnet provides a force to connect and/or align the plug with the port. Once the plug is received within the port, if a process is completed, the coded magnets polarities are altered to eject the plug from the port.

  • Patent number: 8207283
    Abstract: Disclosed is a method for producing a norbornene monomer composition, a norbornene polymer produced using the norbornene monomer composition, an optical film including the norbornene polymer, and a method for producing the norbornene polymer. The method includes reacting a reaction solution that contains cyclopentadiene, dicyclopentadiene, or a mixture of cyclopentadiene and dicyclopentadiene, an acetate compound, and a solvent so that a content of an exo isomer is 50 mol % or more. Variables such as a reaction temperature, a reaction time, a molar ratio between reactants, and addition of a solvent are controlled so that the exo isomer is contained in content of 50 mol % or more. Accordingly, it is possible to industrially produce an acetate norbornene addition polymer by using the acetate norbornene monomer composition containing the exo isomer in content of 50 mol % or more.

  • Publication number: 20120077113
    Abstract: Provided is a microporous organic/ inorganic composite coated layer comprising a heat resistant resin and inorganic particles, formed on at least one side of microporous polyethylene. The microporous polyethylene composite film is characterized by sufficient permeability and heat resistance at the same time, of which the permeability (Gurley) of overall composite film including a coated layer is not more than 300 sec; shrinkage after 150° C. for 1 hour is 0-3% in both MD/TD directions; maximum shrinkage in TMA is not more than 3%, and TMA meldown temperature is 145-200° C. The microporous polyethylene composite film formed by means of the coated layer possesses stability at high temperature as well as excellent permeability, thereby ensuring reliability and efficiency of a battery at the same time. A separator which conforms to high power/high capacity can be provided thereby.
