Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a porous carbon fiber by utilization of starch which is an environment-compatible and low cost natural polymer. SOLUTION: The method for producing a porous carbon fiber includes: a step for processing the starch to produce a gelled starch solution; a step for adding an organic acid to the starch solution to produce the organic acid-added starch solution; a step for dissolving carbon nanotube in a solvent and then adding a fiber-forming polymer to produce a carbon nanotube/fiber-forming-polymer containing solution; a step for further mixing the carbon nanotube/fiber-forming-polymer containing solution with the starch solution to produce the carbon nanotube/starch/fiber-forming-polymer containing solution; a step for producing a starch-composite fiber from the carbon nanotube/starch/fiber-forming-polymer containing solution by an electric spinning method or a wet spinning method; and a step for subjecting the starch composite fiber to oxidizing heat treatment and then further to a carbonization treatment and to a vacuum thermal treatment.

PROBLEM TO BE SOLVED: To provide a higher-order generalized series parallel imaging method and a sampling method for acquiring high spatio-temporal resolution functional magnetic resonance images. SOLUTION: This method for acquiring magnetic resonance images having high spatio-temporal resolution includes: a step of performing sampling of an input image in k-space; a step of applying a higher-order generalized series (HGS) reconstruction procedure to data acquired as the sampling result to acquire a first reconstructed image; and a step of applying a parallel magnetic resonance reconstruction procedure to the first reconstructed image to acquire a second reconstructed image. The image acquisition speed can be made faster and high resolution functional magnetic resonance images can be acquired. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
A method of fabricating a semiconductor device by filling carbon nanotubes in a recess is disclosed. The method of fabricating the semiconductor device comprises patterning a mold on a substrate, coating carbon nanotubes on an entire surface of the recess and the mold formed by the patterning, filling the carbon nanotubes coated on the an entire surface of the mold in the recess, and removing the mold.

PROBLEM TO BE SOLVED: To provide a fuel cell stack fastening equipment in which a face pressure of a fuel cell can be maintained uniformly and package efficiency can be improved. SOLUTION: This equipment is constituted including a wire to fasten end plates attached to both end parts of the stack, a tensioner attached to the upper part of the up-end plate in order to adjust tension of the wire, a tension guide equipped with a center groove in order to guide the vertical movement of the tensioner and formed in a structure surrounding the tensioner, the upper part guides installed on both sides of the tensioner to guide the wires of the stack upper part, and the lower guides attached to both sides of the lower part of the down end plate to guide the wires of the stack lower part. The tensioner is attached to the upper part of the up-end plate with tension bolts, and its vertical height is adjusted by a screw movement method to adjust the tension of the wire.

Abstract:
PROBLEM TO BE SOLVED: To provide a nickel stamp having flexibility. SOLUTION: The nickel-plating solution contains 600 to 650 g/L of nickel sulfamate, 5 to 6 g/L of nickel chloride, and 25 to 35 g/L of boric acid. Such a nickel-plating solution can provide the nickel stamp having flexibility by reducing stress of itself. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method of setting a packet transmission path in an ad-hoc communication network and a network apparatus using the same. SOLUTION: A method of setting a packet transmission path includes steps of: setting N-1 routing regions including at least one node between a source node and a destination node on the basis of a predetermined N number of hops, (N denoting an integer greater than or equal to two); and determining a node in each of the set routing regions as a packet relay node on the basis of a channel gain.
