The present disclosure relates to a method of preparing a laminate or a laminated lens, comprising obtaining a first plastic substrate having a front surface and a back surface, treating the front surface of the first plastic substrate or the back surface of the first plastic substrate, and laminating a second plastic substrate on the treated front surface of the first plastic substrate or the treated back surface of the first plastic substrate. The treating may include applying a polyurethane resin to a surface of the first plastic substrate. The method may further comprise treating a surface of the second plastic substrate. The method may further comprise applying activator to the treated surfaces of the first plastic substrate and the second plastic substrate and laminating by apposing the treated surfaces of the first plastic substrate and the second plastic substrate.

Provided are a film insert molded article, an insert film, and the like that enable realization of complex shapes, that can prevent occurrence of cracks and breaks, and that have an excellent chemical resistance property and abrasion resistance property. This film insert molded article and the like are provided with a shaped curable insert film and a thermoplastic resin layer layered on the insert film, the insert film including a curable hard-coating layer which is uncured.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A method of forming an ophthalmic laminate lens, includes: forming a planar laminate by adhering a first polycarbonate layer to a first side of a thermoplastic elastomer layer, and adhering a second polycarbonate layer to a second side of the thermoplastic elastomer layer, the first polycarbonate layer having a thickness greater than 250 μm, the second polycarbonate layer having a thickness greater than 250 μm, and the thermoplastic elastomer layer having a thickness in a range of 15 μm to 150 μm; thermoforming the planar laminate into a curved laminate, the curve laminate having a pre-molding curvature; arranging the curved laminate in a mold; and molding, via the mold set at a predetermined temperature and a predetermined pressure, the curved laminate with a polymer melt into a curved lens.

The present invention provides an apparatus for manufacturing a plastic optical fiber suitable for adjusting a plastic optical fiber to be uniform in size while inhibiting the entry of a metal that causes an increase in transmission loss of the plastic optical fiber. The apparatus for manufacturing a plastic optical fiber of the present invention is provided with an extruding device and a gear pump. The extruding device has a containing portion that contains a resin composition, and introduces a gas into the containing portion to extrude the resin composition from the containing portion by means of the gas. The gear pump adjusts a flow rate of the resin composition extruded from the extruding device.

A process for forming a container from a blank, the process comprising the steps of: thermally inducing one or more fold lines on at least one surface of a container blank fabricated from a thermal insulation sheet material, wherein the blank comprises: a first panel portion; a second panel portion located adjacent the first panel portion and sharing a first common edge therewith; and a third panel portion located adjacent the second panel portion and sharing a second common edge therewith, the second common edge being substantially parallel to the first common edge, wherein the first panel portion and the third panel portion are each associated with a pair of flap members adapted for folding movement relative to the respective first and third panel portions such that, when assembled, each of the flap members overlies an edge of the second panel portion substantially perpendicular to the first common edge and the second common edge, folding the first panel portion of the container blank along a first fold line, wherein when folded, the first panel portion is substantially perpendicular to the second panel portion of the container blank; folding the third panel portion of the container blank along a second fold line, wherein when folded, the third panel portion is substantially perpendicular to the second panel portion and substantially parallel to the first panel portion; sealing a portion of each of the pair of flap members of the first panel portion to a portion of each of the pair of flap members of the third panel portion to form a side seam joint; and sealing a portion of the first panel portion adjacent the side seam joint and a portion of the third panel portion adjacent the side seam joint to an edge of the second panel portion to form a bottom seam joint.
