  • Publication number: 20170059676
    Abstract: A gradient coil comprises a curved conductor, which is tubular and has a general spiral shape. The curved conductor is formed by a process comprising depositing at least one non-conductive material layer by layer to form a substrate, and coating at least a portion of a surface of the substrate with a conductive material. The substrate has a shape matching with the general spiral shape of the curved conductor. Embodiments of the present disclosure further refer to a method for manufacturing the gradient coil.

  • Publication number: 20170062144
    Abstract: A process for forming a capacitor is presented. The process includes providing a laminate including a dielectric layer disposed on a sacrificial substrate, forming a free-standing metallized dielectric layer and packaging the free-standing metallized dielectric layer to form a capacitor. The dielectric layer includes a polyetherimide. The step of forming the free-standing metallized dielectric layer is performed by: (a) disposing a metal layer on the dielectric layer to form a metalized laminate such that a metalized dielectric layer is formed on the sacrificial substrate, and removing the sacrificial substrate to form the free-standing metallized dielectric layer; or (b) removing the sacrificial substrate from the laminate to form a free-standing dielectric layer, and disposing a metal layer on the free-standing dielectric layer to form the free-standing metallized dielectric layer. A capacitor formed by the process is presented.

  • Patent number: 8383214
    Abstract: A composite article comprises a substrate having at least a substrate surface and a graded-composition coating disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices or materials. An organic light-emitting device incorporates such a composite article to provide an extended life thereto.
