Synthetic closure

By achieving an extruded, foamed core formed from plastic material peripherally surrounded and integrally bonded with a plurality of cooperating synthetic, plastic, extruded, outer layers, a unique, multi-component, multi-layer synthetic closure is provided which may be employed as a bottle closure or stopper for any desired product, whether the product is a liquid, a viscous material, or a solid distributed in a bottle or container and dispensed through the open portal of the container neck. The present invention achieves a mass producible, resilient, synthetic bottle closure which is employable for any desired bottle, including wine. By employing the present invention, a multi-component or multi-layer synthetic closure is attained which possesses physical properties substantially equal to or better than the physical properties found in cork material, which has caused such cork material to be the principal closure material for wine bottles.

Metal-air battery

A metal-air battery is a secondary battery that includes a positive electrode, a negative electrode, an electrolyte layer, and an air introduction pipe. The positive electrode is a porous member having a substantially cylindrical bottomed shape and includes a positive electrode supporter made of alumina, a positive electrode conductive layer made of a perovskite type oxide having electrical conductivity, and a positive electrode catalyst layer made of manganese dioxide. The negative electrode includes a negative electrode supporter made of stainless steel and a negative electrode conductive layer made of lithium or a lithium alloy. The metal-air battery can realize the positive electrode that contains no carbon by forming the positive electrode catalyst layer on the positive electrode conductive layer made of a perovskite type oxide. This enables prevention of the generation of lithium carbonate on the positive electrode during discharge, thus reducing the charge voltage of the metal-air battery.

Semiconductor device

As etch-stop films or Cu-diffusion barrier films used in insulation films constituting conductor layers of a stacked structure, films having smaller dielectric constant than silicon nitride films are used, and an insulation film at a lower-layer part of the stacked structure is made to have smaller dielectric constant than that at an upper-layer part thereof, and further this insulation film is a silicon oxide (SiO) film and has in the interior thereof, nano-pores of from 0.05 nm or more to 4 nm or less in diameter as chief construction. This makes it possible to dramatically reduce effective dielectric constant while keeping the mechanical strength of the conductore layers themselves, and can materialize a highly reliable and high-performance semiconductor device having mitigated the wiring delay of signals which pass through wirings.

Multi-component synthetic closure and method of manufacture

In the present invention, a manufacturing process is provided in which a complete multi-component synthetic closure is achieved which incorporates printed indicia formed thereon, in a continuous, in-line manufacturing operation. In the preferred embodiment of the present invention, the core member of the synthetic closure is formed by a continuous extrusion process which enables the core to be manufactured as an elongated, continuous length of material. As the continuous elongated length of extruded material forming the central core is advanced from the extruder towards an outer skin forming station, the central core passes through a printing station for forming any desired indica on the outer surface of central core prior to the application of the outer skin layer.

Sealing bead

Fuel system components for vehicles may be made from polyethylene components which are typically blow molded. To inhibit fuel vapour permeation, the polyethylene is often co-extruded into a parison with the parison comprising a barrier layer. Upon trimming flash or in the mold closure itself, the barrier layer may be ruptured. Sealing of areas of discontinuity in the fuel system component to inhibit hydrocarbon vapour pass through is achieved by sealing the area of barrier discontinuity with a sealing bead which has the necessary barrier properties. The barrier properties may be inherent in the sealing bead material or in a barrier layer extruded into the sealing bead.
