In an electrode sheet manufacturing device, in a state where an electric potential difference is generated between a gravure roll and a current collecting foil conveyed by a backup roll, a powder mixture made as powder of an electrode active material and powder of a binder are mixed without a solvent is continuously fed into a depressed portion on an outer peripheral surface of the gravure roll, and an electric potential difference is generated between the powder mixture fed into the depressed portion of the gravure roll, and the current collecting foil. Due to electrostatic force acting between the powder mixture and the current collecting foil, the powder mixture is moved from the gravure roll to a surface of the current collecting foil. Circumferential speed of the gravure roll is higher than circumferential speed of the backup roll.

A method for molding a composite material includes a conductive wire-shaped material arrangement step and a magnetic field application step. The conductive wire-shaped material arrangement step is a step for arranging, in a pre-reaction composite material including reinforcing fibers, a plurality of conductive wire-shaped materials along a direction intersecting the reinforcing fibers with intervals wider than intervals of the reinforcing fibers in a plane on which the reinforcing fibers are arranged. The magnetic field application step is a step for applying a magnetic field in a direction intersecting the plane on which the reinforcing fibers are arranged.

The present invention discloses an apparatus and a method for manufacturing molding inductor. The apparatus mainly comprises a mold and at least one magnetic force generating unit. Particularly, the mold is designed to have one or more accommodation spaces to correspondingly receive one or more coils. On the other hand, the magnetic force generating unit is configured to apply a magnetic force to the accommodation spaces after a molding material doped with magnetic ferrite powder is filled into the accommodation spaces receiving with the coil therein. Consequently, the molding material is forced by a molding stress provided by the applied magnetic force to move effectively downward in the accommodation space, such that a molded body is eventually formed in the accommodation space.

A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.
