Continuous sequin strip having a multiplicity of continuously-connected sequins is let out from a reel and then placed on the upper surface of a supporting plate. Sequin feeder apparatus feeds the sequin strip at a predetermined pitch corresponding to a size of a sequin of the continuous sequin strip through advancing and retracting movement of a feed lever interlocked to sewing operation of a needle bar of a sewing machine. The feed lever includes two engaging portions for engaging a predetermined sequin of the strip to feed the strip. With the two engaging portions engaging at least two points of the sequin, the sequin can be fed out reliably irrespective of the position of the sewing hole formed in the sequin. Thus, even sequins, each having the sewing hole eccentrically offset in a direction perpendicular to a sequin-strip feeding direction, can be fed out at the predetermined pitch with an increased reliability.

A method for integrating a Ru layer with bulk Cu in semiconductor manufacturing. The method includes depositing a Ru layer onto a substrate in a chemical vapor deposition process, modifying the deposited Ru layer by oxidation, or nitridation, or a combination thereof, depositing an ultra thin Cu layer onto the modified Ru layer, and plating a Cu layer onto the ultra thin Cu layer.

A semiconductor device containing a ruthenium diffusion barrier and a method of forming and integrating the ruthenium diffusion barrier with bulk Cu. The method includes forming the Ru diffusion barrier by depositing a first Ru layer onto a substrate in a first CVD process, modifying the first Ru layer by oxidation, or nitridation, or a combination thereof, depositing a second Ru layer on the modified first Ru layer, and plating a Cu layer onto the Ru diffusion barrier. According to one embodiment of the invention, the Ru diffusion barrier is treated and/or an ultra thin Cu layer deposited on the Ru diffusion barrier prior to Cu plating.

An object of this invention is to reduce even slight irregularities in illumination that occur after assembly of an optical system. To this end, in an exemplary illumination-optical system, a light source that emits extreme ultraviolet (EUV) light, a collimator, a fly's-eye mirror, and a condenser are positioned, in this stated order. A prescribed illumination area on the emission side of the condenser is irradiated with Köhler illumination. At least one unit mirror, among multiple unit mirrors of the fly's-eye mirror, is a correction mirror that has reflectivity irregularities. The reflectivity irregularities correct a portion of, or all, the illumination irregularities in the illumination area.

A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved.The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.

A control apparatus includes a shift position detecting device for detecting a shift position that is changed by manual operation of the vehicle driver, an ECU for controlling an A/T based on a signal for a detected vehicle running state, and connectors that connect to an electrical unit outside the casing. Further, the shift position detecting device, the connectors, and the electronic control unit are electrically connected through a connecting board. Consequently, the shift position detecting device, the ECU, and the connectors can be freely laid out.

The present invention provides an inorganic separation membrane including a silicalite nanocrystalline layer formed on a porous ceramic substrate, and a porous inorganic protective layer is formed on the nanocrystalline layer. The crystal grain diameter of the silicalite nanocrystal is preferably 150 nm or less, and the thickness of the silicalite nanocrystalline layer is preferably 1.0 to 4.0 μm. The separation membrane may be manufactured by: immersing a porous ceramic substrate in a dispersion solution of silicalite nanocrystals; laminating the silicalite nanocrystals on the surface of the porous ceramic substrate by evacuating the insider of the porous ceramic substrate; forming a porous inorganic protective layer on the silicalite nanocrystalline layer by a hydrothermal synthesis by heating after immersing the porous substrate in a zeolite synthesis solution containing a silica source; and removing organic components in the silicalite nanocrystal by liquid phase oxidation.
