A method is provided for producing a separator by cutting a laminated porous film. The laminated porous film includes a porous base material layer containing polyolefin as a main component and a filler layer containing inorganic particles as a main component. The filler layer is provided on one surface of the porous base material layer; and a resin layer containing resin particles as a main component is provided on the other surface of the porous base material layer. The method includes a step of cutting, using a slit blade, the laminated porous film from the one surface on which the filler layer is provided.

An apparatus for cutting a multilayer material includes a splitter module and a uniaxial crystal element. The splitter module, located in a transmission path of an incident light beam, is used for splitting the incident light beam into a first polarized light beam and a second polarized light beam. The uniaxial crystal element is disposed adjacent to the splitter module and on a transmission path of the first polarized light beam and the second polarized light beam. The first polarized light beam and the second polarized light beam pass through the uniaxial crystal element individually by having the first polarized light beam and the second polarized light in correspondence to different index of refractions, so that two focuses with different focal lengths can be obtained. In addition, a method for cutting a multilayer material method is also provided.

A method for manufacturing a display device includes a stage; a first guide unit positioned on one side of the stage in a first direction and extending in a second direction crossing the first direction; and a first peeling unit disposed on the first guide unit, wherein the first peeling unit includes a first moving part configured to move along the first guide unit, a first rotating part coupled to the other side of the first moving part in the first direction and configured to rotate about an axis extending in the first direction, and a first gripping part coupled to the other side of the first rotating part in the first direction and disposed to overlap the stage.

An object with a conductive element on a receiving carrier layer and a roll-to-roll processing method for manufacturing it. The solution is based on the idea of operating systematically with two different types of adhesives in selected stages of the roll-to-roll processing. A very thin layer of conductive material can be accurately and reliably transferred to adhesively attach on a desired carrier surface.

The invention relates to a method for manufacturing a hybrid structure of a motor vehicle, including a step of assembling a structural element formed of a sheet of shaped metal material and a strip of composite material that includes at least one layer of fibres impregnated or embedded in a polymer matrix, covers a portion of a surface of said structural element, and is extracted from a large rectangular sheet including an upper edge and a lower edge which are parallel to one another, the strip of composite material being obtained by extracting a portion of the large sheet according to a first cut-out line and second cut-out line, each running from the upper edge to the lower edge. Each of the cut-out lines has a point of symmetry arranged equidistantly from the upper edge and the lower edge, such that any given point of a cut-out line is symmetrical, with respect to said point of symmetry, with another point belonging to said cut-out line.

A device for dismantling a liquid crystal display includes a carrier platform, a dismantling bracket, a dividing piece and a driving component; the carrier platform includes a carrying surface for supporting the liquid crystal display to be dismantled thereon, and the liquid crystal display to be dismantled includes a display panel and a backlight unit bonded to each other; the dividing piece is located above the carrier platform and mounted onto the dismantling bracket; the dividing piece is capable of being driven by the driving component so as to move in a first direction and into a slit between the display panel and the backlight unit; and the first direction intersects with an extending direction of the dividing piece. The dismantling device for liquid crystal display can solve the problem that the display panel and the backlight unit are difficult to be dismantled.

A method of debonding a temporarily adhesive-bonded carrier-workpiece pair employs a stream of a solvent at a high pressure. The carrier and the workpiece are bonded with an adhesive that is dissolvable in a selected solvent. The workpiece such as a device wafer may have been thinned and processed. The solvent is applied to the adhesive at a high pressure to debond and dissolve the adhesive with high throughput. The dissolved adhesive can be recycled and later reused, thus lowering the cost of the whole bonding and debonding process.

Method for bonding by wrapping a medium which expands transversely to a winding with an adhesive tape, in which: an adhesive tape is unrolled from an adhesive tape roll, the unrolled adhesive tape is provided on one side of a carrier film (1) with an adhesive cement layer (2) and on an opposite side partially with a separating agent layer (3), wherein the area covered by the separating agent layer (3) takes up not more than 50% of the total area of the carrier reverse side, wherein at least the surface of the side of the carrier film (1) which is furnished with a separating agent layer (3) is etched, the adhesive tape is wound around the medium which expands transversely to a winding, so that at least a portion of the adhesive tape is bonded to a lower winding ply by the adhesive cement layer (2).
