Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.

Provided is an electromagnetic wave shielding material that can exhibit improved electromagnetic wave shielding property, light-weight property and formability. The present invention relates to an electromagnetic wave shielding material comprising a laminate in which N number of metal foils each having a thickness of 5 to 100 μm and N+1 number of resin layers each having a thickness of 5 μm or more are alternately laminated or a laminate in which N+1 number of metal foils each having a thickness of 5 to 100 μm and N number of resin layers each having a thickness of 5 μm or more are alternately laminated, N being an integer of 2 or more, wherein thickness of the laminate is from 100 to 500 μm, and wherein, when a thickness center of the laminate is used as a reference, for all pairs of interfaces at which sequences of the resin layers and the metal foils on both upper and lower sides of the reference correspond to each other, distances from the reference to the interfaces have an error of within ±10%.

The present invention relates to a halogen-free epoxy resin composition, a prepreg, a laminate and a printed circuit board containing the same. The halogen-free epoxy resin composition comprises an epoxy resin and a curing agent. Taking the total equivalent amount of the epoxy groups in the epoxy resin as 1, the active groups in the curing agent which react with the epoxy groups have an equivalent amount of 0.5-0.95. By controlling the equivalent ratio of the epoxy groups in the epoxy resin to the active groups in the curing agent to be 0.5-0.95, the present invention ensures the Df value stability of prepregs under different curing temperature conditions while maintaining a low dielectric constant and a low dielectric loss. The prepregs and laminates prepared from the resin composition have comprehensive performances, such as low dielectric constant, low dielectric loss, excellent flame retardancy, heat resistance, cohesiveness, low water absorption and moisture resistance, and are suitable for use in halogen-free multilayer circuit boards.

A deployable aircraft flotation system. The deployable aircraft flotation system includes a pair of flotation members. The pair of flotation members are positioned on opposing sides of a bottom surface of an aircraft body. Each flotation member of the pair of flotation members has an inner layer that is made of a first buoyant material, an outer layer that is made of a second buoyant material, and a middle layer between the inner layer and the outer layer that is made of a rigid material. The flotation members can be moved from a stowed position, where they are stored in housings, to a deployed position, where they emerge and are positioned on the bottom of the plane.

An electrically grounded wear resistant liner is described that inserts into a conventional frac sand delivery conduit. The liner allows for conveyance of highly abrasive materials through the liner and conduit while electrically grounding potential static build up from within the liner. Sand, cement and other abrasive slurries may be conveyed through the liner. The wear resistant liner extends the amount of time that the conduit may be used to convey materials without downtime for replacement and repairs. The liner further provides a tri layer construction that includes a middle layer having a color notably different than the outer and inner layers, allowing a user in the fields to quickly determine that the conduit should be replaced.

Battery packaging material wherein a sheet-like laminated body is formed by sequentially stacking at least a base layer, metal layer, and sealant layer, the battery packaging material being equipped with substantially rectangular space that is formed to protrude from the sealant layer side toward the base layer side, and accommodates a battery element on the sealant layer side. In planar view from the base layer side view, a first and second curved sections are provided from the center portion toward the battery packaging material end parts, in a cross section in the thickness direction on a line connecting opposing corner parts protruding in a substantially rectangular shape. The thickness (a) of the metal layer at the first curved section, (c) of the metal layer at the second curved section, and (b) of the metal layer at the section located between the first and second curved sections, satisfy the following relationship a≧b>c or a≧c>b.
