    摘要: An induction heated tool system for receiving and heating polymer-fiber components from a starting temperature to a target temperature includes a tool part having a receiving cutout, the tool part formed from a thermally dimensionally stable material so it has a coefficient of thermal longitudinal expansion less than 10×10−6 K−1, or less than 5×10−6 K−1, or less than 4×10−6 K−1 in the plane of the largest dimension of the receiving cutout, at temperatures between the starting and target temperatures. A receiving cutout for receiving a polymer-fiber component is in the tool part, the receiving cutout delimited by a receiving surface portion so a polymer-fiber component received in the receiving cutout can lie against the receiving surface portion. A susceptor element includes a ferromagnetic material with a first Curie temperature. The susceptor element is on a surface portion of the tool part outside the receiving cutout and the receiving surface portion.

    摘要: A method for forming an electromagnetic shielding material includes causing a first portion of a matrix material to enter a target region of a magnetic field, thereby causing first ferromagnetic particles within the first portion of the matrix material to move such that first longitudinal axes of the first ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the first portion of the matrix material within the target region of the magnetic field and thereafter causing a second portion of the matrix material to enter the target region of the magnetic field, thereby causing second ferromagnetic particles within the second portion of the matrix material to move such that second longitudinal axes of the second ferromagnetic particles become more aligned with the magnetic field. The method also includes curing the second portion of the matrix material within the target region of the magnetic field.

    摘要: Systems and methods for compensating for nonuniform surface topography features in accordance with various embodiments of the invention are illustrated. One embodiment includes a method for manufacturing waveguide cells, the method including providing a waveguide including first and second substrates and a layer of optical recording material, and applying a surface forming process to at least one external surface of the first and second substrates. In another embodiment, applying the surface forming process includes applying a forming material coating to the at least one external surface, providing a forming element having a forming surface, bringing the forming element in physical contact with the forming material coating, curing the forming material coating while it is in contact with the forming element, and releasing the forming material coating from the forming element.
