摘要:
A tubular wall, which may be employed in a medical catheter or medical electrical lead, is formed by stranding together a plurality of polymer fibers and at least one metal filar, wherein the stranding forms a braid matrix of the polymer fibers and a coil of the metal filar interlaced therewith. Then, while the braid matrix secures a pitch of the coil, a polymer material is extruded around an entire length of the tubular wall, and, in some cases, the extrusion process causes the plurality of polymer fibers to melt and coalesce together with one another, while the pitch of the coil is maintained. Alternately, a reflow process, which follows extrusion, causes the polymer fibers to melt and coalesce along all, or just a discrete length of the tubular wall.

An object of the present invention is to provide a method of manufacturing a liquid crystal alignment film which does not lose a function as a liquid crystal cell even in a case where three-dimensional formation is performed with a high degree of freedom, a method of manufacturing a three-dimensional liquid crystal cell using the method of manufacturing a liquid crystal alignment film, and a three-dimensional liquid crystal cell produced by the method of manufacturing a three-dimensional liquid crystal cell. A method of manufacturing a liquid crystal alignment film of the present invention includes a step of arranging a liquid crystal alignment agent to a heat-shrinkable film satisfying a heat shrinkage rate of 5% to 75%, and a step of drying the liquid crystal alignment agent arranged at 40° C. to 150° C. so as to form the liquid crystal alignment film.

A tape dispenser, joining and dispensing a double-sided tape from two rolls of single-sided tape, includes a base having upper and lower sides, first and second spaced apart guide elements mounted to the upper side at first and second positions. First and second tape dispensing wheels, having rolls of single-sided tape mounted thereto, are mounted to the rearward portion of the upper side of the base. A handle extends from the lower side. A tape application roller is mounted to the forward portion of the base and extends above the upper side. A tape cutoff blade, or first and second cutoff blades, can be mounted to the base and extend above the upper side. An extension handle extending transversely to the handle, which can be at least 2 feet long or at least 4 feet long, can be removably mountable to the base plate.

Cured ethylene terpolymer attaches a film to the metal surface of a condensing heat exchanger of a condensing furnace to prevent corrosion of the condensing heat exchanger. After applying a layer of ethylene terpolymer to the metal surface of the condensing heat exchanger, a film is positioned on the layer. Water reacts with the organosilicone functional groups on the ethylene terpolymer chain, cross-linking the organosilicone functional groups and adhering the film to the surface of condensing heat exchanger. The water is provided in the film or is added by an external source. Preferably, the film is polar to encourage adhesion of the water to the film and encourage cross-linking of the organosilicone functional groups.

A process for coating surfaces in apparatuses or apparatus parts for plant construction, preferably for chemical plant construction, involves optionally first hydrophobicizing a polymer film having a microstructured and optionally additionally macrostructured surface and then fixing it on the apparatus or apparatus part to be coated, and also apparatuses and apparatus parts thus coated.

Molding, such as that used in the manufacture of picture frames, is laminated with a covering wrap of foil, paper, plastic, cloth, or wood veneer and is embossed on the same machine shortly thereafter. The covering wrap is adhered by an adhesive and the embossed pattern is formed in part by pressure of a pattern against the substrate and through the covering wrap and partly by forcing of the adhesive used in the laminating process into various raised portions of the pattern, thus supporting and enhancing the embossed profile.

A core panel or box of rigid plastics microporous foam is provided with parallel spaced passages or thin grooves and is placed within an envelope or bag of flexible multi-layer barrier film impervious to the passage of gas. The bag includes an integral evacuation tubular portion which is releasably coupled to an evacuation nozzle connected by a manifold with solenoid valves to a vacuum pump. After air is substantially evacuated from the foam core and the bag to collapse the bag against the foam core and into the grooves, a vacuum sensor operates a computer which controls the valves for checking the vacuum level within the bag and for optionally admitting an additive gas. Closely spaced grooves within opposite sides of the foam panel provide for bending the evacuated panel, and a thin layer of foam is applied to the outer surface of the vacuum insulated panel to provide a protective outer surface.

A printing method for producing a print having large visual effects mat processing the surface of a print made by an ink ribbon and a thermal transfer head. The images of color components of yellow, magenta, and cyan 52 are sequentially formed on a printing paper 23, and thereafter, a lamination film 53 is stuck to the entire image face in the same process. At this time, a silk texture or random concave-convex pattern is formed on the lamination film 53 and the mat processing having the large visual effects is performed.
摘要:
The invention provides that flexible lining tubes for application to underground pipelines and passageways comprise absorbent material which is impregnated with curable synthetic resin which can be cured when the tube is placed on the pipeline or passageway surface so that a rigid pipe within the pipe is formed. The curing of the resin is controlled by filling the curing agent into micropores or microporous particles which are dispersed throughout the resin. The curing agent is only released when the resin is subjected to applied energy such as sonic and/or heat energy. A preferred method is to include CURIE temperature magnetic particles in the resin and to excite (and thus heat) the magnetic particles by applying an alternating high frequency magnetic field. The heat from the magnetic particles opens the microporous particles and causes desorbence of the curing agent and then cure of the resin. The invention also provides that the curing agent is absorbed into the absorbent layer in the first place using sonic energy.
