An insulated metal substrate (IMS) and a method for manufacturing the same are disclosed. The IMS includes an electrically conductive line pattern layer, an encapsulation layer, a first adhesive layer, a second adhesive layer, and a heat sink element. The encapsulation layer fills a gap between a plurality of electrically conductive lines of the electrically conductive line pattern layer. An upper surface of the encapsulation layer is flush with an upper surface of the electrically conductive line pattern layer. The first and second adhesive layer are disposed between the electrically conductive line pattern layer and the heat sink element. A bonding strength between the first adhesive layer and the second adhesive layer is greater than 80 kg/cm.sup.2.

Micromorphologically crack-free vitreous carbon articles having a length and width each of which is at least 10 mm, and a thickness of at least 5 mm are described, as well as multilayer laminates of micromorphologically crack-free vitreous carbon, and corresponding methods and apparatus for manufacture of same. 3D printed vitreous carbon articles are also described, together with 3D printing apparatus and methods for producing same. Methods are also described for forming vitreous carbon containing vitreous carbon nanolattice articles therein as filler. The vitreous carbon compositions, articles, and laminates of the disclosure overcome the thickness limitations of conventional vitreous carbon manufacturing methods and the microcracking issues attendant previous efforts to produce vitreous carbon of substantial size and thickness.

A laminate manufactured by forming a step difference in a substrate by grinding a periphery edge portion to have such a size that a surface on the inner side of the step difference can be housed in a cavity of a die, and then laminating the substrate, an adhesive layer, a release layer, and a support plate in this order such that the surface on the inner side of the step difference of the substrate faces the support plate.

A polarizing film, comprising a polarizer; transparent protective films with a water-vapor permeability of 150 g/m2/24 hours or less provided on both sides of the polarizer; and adhesive layers each interposed between the polarizer and one of the transparent protective films, wherein the adhesive layers are formed by applying an active energy ray to an active energy ray-curable adhesive composition containing a radically polymerizable compound, and the transparent protective films are bonded to the polarizer with the adhesive layers.

Heat de-bondable optical articles include two optical substrates and a heat de-bondable adhesive article disposed between them. The adhesive article includes a heat-shrinkable substrate and an optically clear adhesive proximate to the heat-shrinkable substrate. Optical articles can be prepared by disposing the heat-shrinkable substrate and the optically clear adhesive between two optical substrates. The optically clear adhesive covers a majority of the surface area of the optical substrates, and the heat-shrinkable substrate is located near the edge of the optical substrates.

Provided are laminating apparatus and method. A laminating apparatus includes a jig assembly, which includes the first jig and an elastic member, and a second jig. A laminating method includes placing a first plate on a jig assembly, placing a second plate on a second jig which is placed to face the first jig, bringing the second plate into contact with the adhesive layer by making the jig assembly and the second jig approach each other, and, attaching the first plate and the second plate to each other by making the jig assembly and the second jig approach closer to each other. The jig assembly includes a first jig and an elastic member which comprises a top portion and sloping portions sloping downward from the top portion. An adhesive layer is disposed between the first plate and the second plate.

A laminate film manufacturing method is capable of preventing thickness unevenness of a cured layer and preventing wrinkling of the entire laminate film. A laminate film is manufactured by applying a coating solution including an active radiation curable resin to a surface of a first film that is continuously transported in an application part to form a coated film in a lamination part, laminating a second film that is continuously transported on the coated film to sandwich the coated film between the first film and the second film, and in a state in which the coated film is sandwiched between the first film and the second film, winding the first film around a backup roller and irradiating the coated film with infrared rays from an ultraviolet irradiation device while continuously transporting the first film to cure the coated film in a curing part so as to form a cured layer.

A manufacturing procedure for ceiling trims for vehicles, the structure of which comprises at least one first coating sheet and at least one second coating sheet that extend along one of the sides of the first sheet, joined via a layer of heat-stable polyurethane adhesive, comprising a step of applying a gas-phase catalyst on such sheets through a thermoforming mould that starts before the mould is completely closed and ends before the mould is completely opened. As a result of said application of a gas-phase catalyst we prevent the use of demoulding agents to facilitate extraction of the ceiling trim formed inside the mould.

A method of manufacturing a stereoscopic image display device includes forming a groove by etching an edge portion of a rear surface of a lens array substrate, depositing a sticky material layer in the groove, disposed a transparent adhesive layer that differs from the sticky material layer onto a top surface of a display panel, aligning the lens array substrate and the display panel by using a camera, and joining the display panel and the lens array substrate by using the transparent adhesive layer.

The invention relates to a method of making an acoustic product and a novel acoustic product, wherein the acoustic product is made by adhering a facing to a first major surface of an acoustic insulation element by the use of an adhesive and curing the adhesive. The adhesive is an aqueous adhesive composition which comprises a component (i) in form of one or more oxidized lignins; a component (ii) in form of one or more cross-linkers; a component (iii) in form of one or more plasticizers.
