A resin sheet having: a surface layer having hair-like bodies arranged regularly on one surface thereof; and a second layer directly laminated to a surface opposite that of the hair-like bodies of the surface layer, the surface layer comprising a thermoplastic polyurethane resin and the second layer comprising a polymer alloy resin of a polycarbonate-based resin and a polyester-based and resin.

Cables are constructed with extruded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket.

A method for producing a sandwich panel with a reinforced foam core includes inserting rod-shaped, thermoplastic reinforcing elements into a thermoplastic foam material such that the reinforcing elements extend through the foam material. End regions of the reinforcing elements project out of the foam material. The foam material is thermoformed to form a reinforced foam core, wherein the end regions of the reinforcing elements are integrally formed by applying temperature and pressure to the cover surfaces of the foam material and are bonded to the foam material in a fused connection. A thermoplastic cover layer is laminated on either side by applying temperature and pressure to the reinforced foam core on the cover surfaces of the foam material in order to form the sandwich panel, wherein the cover layers are bonded to the reinforced foam core in a fused connection.

The present invention relates to an encapsulated phase-change material (1) comprising a phase-change material (3) contained within a tube (5), said tube (5) being made of plastic and that it has a sealing weld (9) at least at one of its ends.

According to at least one embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (γ) a hard coat on at least one surface of (α) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4′-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %. According to another embodiment, there is provided a hard coat laminate film having a total light transmittance of 80% or more and having (γ) a hard coat on at least one surface of a transparent laminate film constituted of (α) an aromatic-polycarbonate resin film containing 30 mol % or more of a structural unit derived from 4,4′-(3,3,5-trimethylcyclohexane-1,1-diyl)diphenol, when the total of the structural units derived from aromatic dihydroxy compounds is 100 mol %, and (β) a poly(meth)acrylimide resin film.

A semi-finished ophthalmic lens for formation of a plurality of different finished ophthalmic lenses requiring reduced amounts of lens material to be removed for formation of the finished ophthalmic lenses and reduced rates of departure of a surfacing tool and methods of making the same.

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.
