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 indicia on the outer surface of the central core prior to the application of the outer skin layer.

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.

The image forming apparatus comprises: an ejection head which ejects droplets having electro rheological effects onto a recording medium; a holding device which holds the recording medium, the holding device being disposed at a position facing an ejection side surface of the ejection head, the recording medium interposing between the ejection head and the holding device; a pair of electrodes which is disposed on the holding device, the pair of electrodes comprising a first electrode and a second electrode; and a voltage application device which applies a voltage to the pair of electrodes.

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.

The present invention provides a solenoid valve coil assembly, comprising: a coil frame wound with a coil; one end of which is connected to the first insertion piece of the live wire of the power supply, one end of which is connected to the zero wire of the power supply, and the other end is connected to the The second insertion piece of the coil, and the third insertion piece whose one end is connected to the coil; the current limiting element installed between the other end of the first insertion piece and the other end of the third insertion piece. The invention can effectively meet the design requirements of the electric connection between the coil and the current limiting element, increase the force of the movable iron core driven by the magnetomotive force, simplify the production process of the electromagnetic valve, and reduce the production cost.

The present invention provides a fabric having soil resistance and no oil stains after wiping and a manufacturing method thereof. The fabric of the present invention comprises an underlayer and a soil-resistant protection film, which can effectively prevent oil corrosion, penetration, and permeation of the surface of the fabric, thus resulting in no oil stains after wiping. The manufacturing method of the present invention comprises the steps of dyeing, setting, performing an underlayer surface treatment to form an underlayer on a surface of the fabric, and performing a soil resistance processing treatment to form a soil-resistant protection film on the surface of the underlayer.

A closure for a container is disclosed. The closure comprises a core member comprising at least one thermoplastic polymer, and at least one peripheral layer at least partially surrounding and intimately bonded to at least one surface of the core member, said peripheral layer comprising at least one styrene block co-polymer, wherein the core member has a density in the range of from about 100 kg / m3 to 350 kg / m3 and the peripheral layer has a density in the range of from greater than 350 kg / m3 to about 1,500 kg / m3 and a thickness in the range of from 0.15 mm to less than 0.50 mm.
