The double bag vacuum infusion process of the present invention provides a low cost method for producing complex composite assemblies without an autoclave. It also enables the production of highly innovative structures. The quality of the composites produced using such an infusion process are comparable to composites made using prepregs, hand layup or fiber placement, and autoclave curing. Double bagging provides vacuum integrity, controls bag relaxation while flow media controls the flow front to allow high quality aerospace-grade products.

Composite ALD-formed diffusion barrier layers. In a preferred embodiment, a composite conductive layer is composed of a diffusion barrier layer and/or a low-resistivity metal layer formed by atomic layer deposition (ALD) lining a damascene opening in dielectrics, serving as diffusion blocking and/or adhesion improvement. The preferred composite diffusion barrier layers are dual titanium nitride layers or dual tantalum nitride layers, triply laminar of tantalum, tantalum nitride and tantalum-rich nitride, or tantalum, tantalum nitride and tantalum, formed sequentially on the opening by way of ALD.

It is used with a fuel injection system for an internal combustion engine which supplies fuel to an injector (fuel injection valve) from a common rail (accumulator) through a high-pressure pipe to spray the fuel from a spray hole formed in the injector. A thin-walled portion 70bz is formed in a path member (e.g., an injector body 4z, the high-pressure pipe, or a connector 70z connecting the injector and the high-pressure pipe) and defined by a locally thin wall of the path member. A strain gauge 60z (strain sensor) is affixed to the thin-walled portion 70bz to measure strain of the thin-walled portion 70bz arising from the pressure of fuel in a high-pressure fuel path 70az.

Backthinning in an area selective manner is applied to imaging sensors 12 for use in electron bombarded devices. A further arrangement results in an array of collimators 51 aligned with pixels 42 or groups of pixels providing improved image contrast of such image sensor. Provision of a thin P-doped layer 52 on the illuminated rear surface provides both a diffusion barrier resulting in improved resolution and a functional shield for reference pixels. A gradient in concentration of P-doped layer 52 optimizes electron collection at the pixel array.

A method of fabricating a flash memory is provided. A substrate having several device isolation structures for defining an active region is provided. A tunneling dielectric layer and a patterned mask layer are sequentially formed over the active region of the substrate. A sacrificial layer is formed on the substrates. Thereafter, the sacrificial layer is patterned to retain a part of sacrificial layer on the device isolation structures. The patterned mask layer is removed, and a conductive layer that exposed the top section of the sacrificial layers is formed over the substrate. After removing the sacrificial layer, an inter-gate dielectric layer is formed over the substrate. A control gate is formed over the inter-gate dielectric layer. Finally, a source region and a drain region are formed in the substrate on each side of the control gate.

The present invention relates to a nano-crystal thin film and a low temperature preparation method. The thin film is provided with graded structure and uses nano-crystal titania particles of different sizes as raw materials to add specific chemical bonds or function masses to the surfaces of the nano-crystal particles through a method of surface modification. The materials are mixed in inorganic or organic solution to be prepared into carcass slurries before graded, which are made into films on a flexible conductive basement or any other basement through a simple film making method. Under a low reaction temperature, the particles in the thin films are well connected through chemical sintering, and the nano-crystal particles are connected through good chemical bonds. The whole thin film is provided with high mechanical strength. Flexible dye sensitization solar energy batteries, which are assembled from the thin films, are provided with the high photoelectric conversion efficiency. The thin film and the low temperature preparation method is predicated to be provided with a wide application prospect in photoelectric transformation and photo-catalyst fields.

The self-supporting aerial optical cable comprises a cable core, an outer sheath, a reinforcing element, a suspension wire sheath and a rib, wherein the cable core is coated by the outer sheath; the reinforcing element is made of a single steel wire or glass fiber reinforced plastics and is coated by the suspension wire sheath; the rib is used for connecting the suspension wire sheath with the outer sheath; the cable core is formed by a central reinforcer, a plurality of loose tubes and a protective layer, wherein the loose tubes are arranged outside the central reinforcer and are coated by the protective layer; at least an optical fiber is arranged in each loose tube; two marking strips are symmetrically arranged on the suspension wire sheath; the suspension wire sheath, the outer sheath and the rib, which are made of the same materials, are formed integrally; and the marking strips are made of special materials. The self-supporting aerial optical cable has the main beneficial effects that the thickness of the suspension wire sheath is more convenient to control; the suspension wire sheath is smoother and round; the product production speed is higher and the percent of pass of the product is higher; the dead weight of the optical cable is lighter and the suitable span is longer; and the colors of the marking strips are more stable.

Photochromic polyurethane laminates and methods for the formation of same wherein a photochromic polyurethane layer of the laminate is interposed between two primer coated transparent resin sheets.

A process for depositing a substantially pure, conformal metal layer on one or more substrates through the decomposition of a metal-containing precursor. During this deposition process, the substrate(s) is maintained at a temperature greater than the decomposition temperature of the precursor while the surrounding atmosphere is maintained at a temperature lower than the decomposition temperature of the precursor. The precursor is dispersed within a transport medium, e.g., a vapor phase. The concentration of the metal-containing precursor(s) in the vapor phase, which also contains liquid therein, can be at a level to provide conditions at or near saturation for the metal precursor(s). In ensuring the aforementioned temperature control between the transport media and substrate, and in maintaining saturation conditions for the transport media, the quality of the deposited metal thin film is markedly improved and the production of by-product metal dust is greatly reduced or substantially eliminated.
