A transparent conductive film wherein carbon nanotubes are discursively embedded in the surface portion of a resin film is produced by (A) dispersing carbon nanotubes on a substrate surface, (B) forming a transparent resin film over the substrate on which the carbon nanotubes are dispersed, and then (C) separating the thus-formed resin film. This is a novel technique for realizing a highly transparent conductive film which is flexible and highly conductive even when amount of carbon nanotubes used therefor is small.

Provided are a substrate processing apparatus and a method of manufacturing a semiconductor device which are able to form a conductive film, which is dense, includes a low concentration of source-derived impurities and has low resistivity, at a higher film-forming rate. The substrate processing apparatus includes a processing chamber configured to stack and accommodate a plurality of substrates; a first processing gas supply system configured to supply a first processing gas into the processing chamber; a second processing gas supply system configured to supply a second processing gas into the processing chamber; and a control unit configured to control the first processing gas supply system and the second processing gas supply system. Here, at least one of the first processing gas supply system and the second processing gas supply system includes two nozzles which are vertically arranged in a stacking direction of the substrates and have different shapes, and the control unit is configured to supply at least one of the first processing gas and the second processing gas into the processing chamber through the two nozzles having different shapes when films are formed on the substrates by supplying the first processing gas and the second processing gas into the processing chamber at pulses having different film-forming rates.

A micro-electro-mechanical (MEMS) switch (10, 110) has an electrode (22, 122) covered by a dielectric layer (23, 123), and has a flexible conductive membrane (31, 131) which moves between positions spaced from and engaging the dielectric layer. At least one of the membrane and dielectric layer has a textured surface (138) that engages the other thereof in the actuated position. The textured surface reduces the area of physical contact through which electric charge from the membrane can tunnel into and become trapped within the dielectric layer. This reduces the amount of trapped charge that could act to latch the membrane in its actuated position, which in turn effects a significant increase in the operational lifetime of the switch.

A lithium-sulfur battery is disclosed in one embodiment of the invention as including an anode containing lithium and a cathode comprising elemental sulfur. The cathode may include at least one solvent selected to at least partially dissolve the elemental sulfur and Li2S_x. A substantially non-porous lithium-ion-conductive membrane is provided between the anode and the cathode to keep sulfur or other reactive species from migrating therebetween. In certain embodiments, the lithium-sulfur battery may include a separator between the anode and the non-porous lithium-ion-conductive membrane. This separator may prevent the lithium in the anode from reacting with the non-porous lithium-ion-conductive membrane. In certain embodiments, the separator is a porous separator infiltrated with a lithium-ion-conductive electrolyte.

Alkali metals and sulfur may be recovered from alkali polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte solution includes an alkali polysulfide and a solvent that dissolves elemental sulfur. A catholyte solution includes alkali metal ions and a catholyte solvent. Applying an electric current oxidizes sulfur in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Sulfur is recovered by removing and cooling a portion of the anolyte solution to precipitate solid phase sulfur. Operating the cell at low temperature causes elemental alkali metal to plate onto the cathode. The cathode may be removed to recover the alkali metal in batch mode or configured as a flexible band to continuously loop outside the catholyte compartment to remove the alkali metal.

The invention concerns a membrane electrode unit (MEU) for electrochemical equipment, especially for membrane fuel cells. The membrane electrode unit has a “semi-coextensive” design and contains an ionically conductive membrane, two catalyst layers, and gas distributor substrates of different sizes on the front and back sides. The first gas distributor substrate has smaller surface dimensions than the ionically conductive membrane, while the second gas distributor substrate has the same area as the ionically conductive membrane. The membrane electrode unit has, because of its special design, a stable structure that can be handled well, and which exhibits advantages for sealing the reactive gases off from each other and in its electrical properties. In particular, the hydrogen penetration current is distinctly reduced. The membrane electrode unit is used in PEM fuel cells, direct methanol fuel cells, electrolyzers, and other electrochemical equipment.

This invention provides a very sensitive optical attenuator, which can be used to couple and attenuate optical signals between optical fibers with a wide range of attenuation level. Such an optical attenuator includes a flexible conductive membrane to be moved by an external force, such as electrostatic force, to achieve deformation of the conductive membrane. The conductive membrane can be formed, for example, by a vacuum deposited silicon nitride film. A thin metallic, conductive layer is then deposited on the flexible membrane to form a reflective mirror to receive and reflect incident optical signals. The semiconductor structure includes one or more spacing posts, with which the first structural member is to be joined and bonded. Electrodes are placed on the semiconductor structure in close proximity to the flexible membrane. At various areas of the semiconductor structure, additional spacing posts are added to cause deformation of the conductive membrane when a voltage is applied between the membrane and the electrodes on the semiconductor structure.
