Nitrogen-containing alloy and method for producing phosphor using the same

InactiveUS20090140205A1Suppress rapid progressHigh performanceLuminescent compositionsFluorescenceNitrogen gas
There is provided a method for industrially producing a phosphor with high performance, in particular, high brightness. There is also provided a nitrogen-containing alloy and an alloy powder that can be used for the production method. A method for producing a phosphor includes a step of heating a raw material for the phosphor under a nitrogen-containing atmosphere, in which an alloy containing two or more different metal elements constituting the phosphor is used as the whole or part of the raw material for the phosphor, and in the heating step, the heating is performed under conditions such that the temperature change per minute is 50° C. or lower.It is possible to suppress the rapid progress of a nitridation reaction in heat treatment in producing the phosphor using an alloy for a phosphor precursor as the whole or part of the raw material, thereby industrially producing the phosphor with high performance, in particular, high brightness.

Functional Device and Method for Making the Same

To provide a functional device suitable for dye-sensitized solar cells and the like and having a structure suited for thickness reduction, and a method for making the same with good productivity. A dye-sensitized photovoltaic device 10 is constituted by a transparent substrate 1 formed of glass or the like, a transparent conductive layer 2 formed of FTO or the like, semiconductor electrode layers (negative electrodes) 3 supporting a photosensitizing dye, an electrolyte layer 4, a film-shaped counter electrode (positive electrode) 5, a film-shaped packaging member 6 replacing a counter substrate of the related art, a sealing member 7, power-collecting wiring 8, a wiring protecting layer 9, and the like. As the material of the film-shaped packaging member 6, a material that has high barrier property of suppressing passage of solvents, gasses, water, and the like and excellent resistance to organic solvents and heat is preferred. The device 10 is sealed by joining the transparent substrate 1 to the film-shaped packaging member 6 but a part 11b of a joint 11 is left unjoined before introduction of an electrolytic solution so as to function as an introduction port and joined after the introduction of the electrolytic solution, thereby requiring no end seal.

Integrated lead suspension for high density drive

The integrated lead suspension assembly comprises several improvements. An oversized terminating pad for the electrical traces and a smaller adjacent insulation layer on the flexure assembly enable laser solder ball bonding of the pads to the read/write terminal contacts on the slider without clamping operation. Consequently, the tip of the load beam can be made narrow for a structure that provides for head loading and unloading functions, which improves the dynamic performance of the suspension assembly. The flexure assembly is configured such that it requires no permanent bending in its forming process, and any permanent bending required is done to the load beam. The limiter that limits the travel of the flexure assembly is formed on the load beam and it is bent to the functional position only after attachment of the flexure assembly to the load beam. The limiter is configured and positioned at the leading edge side of the slider to optimize the unloading process and to minimize the possibility of disengagement of the limiter and the flexure assembly during high shock environment. Asymmetric backing branches are provided for the read and write traces in the flexure assembly located at the hinge area of the load beam, the widths of which are sized to optimize the dynamic signal performance of the read and write traces without impact on the vertical stiffness of the suspension. Low profile flanges at 30°–60° that bend from the plane of the load beam are provided along the edges of the load beam to optimize bending stiffness and flow induced vibration. Dimples are provided along the load beam to facilitate insertion of a plastic head separation tool.

Split-Ring Gland Pipe Coupling with Corrugated Armor

A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and at least one annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap. The pipe coupling includes an armor positioned to span the gap between the spaced ends to provide a generally closed annular periphery about the gasket. The armor includes a corrugated portion having a plurality of corrugations engaging the split-ring gland and the gasket during compression of the gasket. The armor is cold formed to improve structural strength and durability.

Traversing reverse circulating drilling method of horizontal directional drilling pipeline and special drilling bit

The invention provides a traversing reverse circulating drilling method of a horizontal directional drilling pipeline and a special drilling bit, which are suitable for laying oil-gas pipelines and municipal pipelines. The drilling method comprises the following steps of: mounting a gravel pump at the outer end of a drilling machine or a pit, wherein hollow cavities are formed in the drilling bit and the drilling stem in use; arranging a slag suction port communicated with a borehole circular space on a reaming drilling bit; sleeving a roller cone seat with a roller cone outside the body of the reaming drilling bit, wherein the position of the roller cone corresponds to that of the slag suction port; arranging a plug for blockage at one end of the reaming drilling bit; and circularly flowing slurry according to a flowing direction from a slurry pond to the borehole circular space, the reaming drilling bit, the drilling stem, the gravel pump and the slurry pond during drilling so as to reach the aim of deslagging. The method and the drilling bit of the invention can be adopted to effectively remove drilling slag and gravel in the horizontal borehole and solve various problems in the traversing construction of the large-diameter horizontal directional drilling pipeline.
