A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A fluororesin having a reactive functional group, wherein the difference between the loss elastic modulus at 270° C. of the fluororesin (G″.sub.270) and the loss elastic modulus at 280° C. of the fluororesin (G″.sub.280) (G″.sub.270-G″.sub.280) is 2,500 Pa or more. Also disclosed is a fluororesin layer containing the fluororesin; and a non-fluororesin layer containing a non-fluororesin.

Systems and methods for creating a grip surface (104) of a protectant glove (100). The method may comprise dipping a glove mold into a coagulant material (206); dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove (208), wherein a biodegradable material is distributed throughout the nitrile coating formulation; vulcanizing at least the outer surface of the glove to form a protectant outer surface (212); washing at least the outer surface of the glove with an enzyme solution; decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface (216); and drying the glove to form a final glove comprising the grip surface (218).

The invention relates to a welding device (1) for producing tubular bodies by the edge-side welding of two substrate edges (2, 3), in particular two laminate edges, said welding device having a continuous, circulating first contact belt (5) for coming into contact with the substrate (4), and an energy source (12, 13) for providing welding energy. According to the invention, the first contact belt (5) has a seamless polyimide contact surface (35) for coming into contact with the substrate (4).

A selectively chrome plated object having a substantially flush interface comprises a first portion formed by injection molding a plateable resin and defining a first top surface, a second portion formed by injection molding a non-plateable resin and defining a second top surface, the second portion sitting proud of the first portion such that the second top surface of the second portion is offset from the first top surface of the first portion, and a third portion formed by a chrome plating process where a chrome plating is applied to the first top surface of the first portion such that a third top surface of the third portion is substantially flush with the second top surface of the second portion.

Described is a medical device lead including a lead body having a conductor lumen including an inner surface. The lead also includes a conductor assembly extending through the conductor lumen; the conductor assembly comprising a conductor member and an outer insulative layer; and an electrode coupled to the conductor cable. The outer insulative layer includes a textured external surface that reduces the coefficient of friction between the outer insulative layer and the inner surface of the conductor lumen through which the conductor assembly extends. Methods of forming the conductor assembly are also described.

A method of manufacturing a polyolefin foam sheet composition includes extruding a polyolefin sheet, irradiating the extruded sheet to obtain a physically crosslinked sheet, foaming the physically crosslinked sheet with heat to obtain a foamed layer, and skiving the foamed layer to obtain a foam sheet with at least one skived surface. The surface roughness of the skived surface of the foam sheet is different from the surface roughness of an unskived surface.

A resin molded product that is applied to a vehicle display device has a surface on which a plurality of fine irregularities having surface roughness of equal to or larger than 1.0 μm and equal to or smaller than 10.0 μm and an array pitch of equal to or larger than 3.0 μm and equal to or smaller than 18.0 μm are molded. In other words, the resin molded product has the surface on which the fine irregularities causing a gloss value at an incident angle of 85° to be equal to or lower than 2 are molded. This configuration provides an effect that the resin molded product and the vehicle display device can lower gloss of the surface.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A composite including a metal member and a resin mold formed jointed to a surface of the metal member is provided, wherein the metal member has a roughened portion in a joint to the resin mold in the surface, and in a specific interface region including a joint interface between the roughened portion and the resin mold, the average volume in a unit area of voids between the roughened portion and the resin mold is 0.05 μm.sup.3 or smaller per 1 μm.sup.2 of a plane generally parallel to the joint interface, and the maximum dimension of the void is 1000 nm or smaller.
