The invention relates to a micro-reformer using a liquid fuel such as methanol and a manufacturing method thereof. The reformer for producing hydrogen gas from the liquid fuel includes a first substrate having a first grooved path and a catalyst layer, and a second substrate having a second grooved path and a catalyst layer, the first and second grooved paths are overlapped on each other forming a micro-channel. The micro-channel has a fuel inlet, a hydrogen outlet, a reforming section, and a carbon monoxide removing section with heating means disposed therein. Although reduced in size, the reformer allows increased hydrogen emission amount due to increased area of the inner path, and is operable with low power due to effective disposition of a heater. This allows manufacturing at low costs and mass-production via semiconductor process.

The home bar includes a home bar frame tightly mounted at the inside of an opening, which is formed at a door of the refrigerator door such that the opening communicates with the inside of the refrigerator, a home bar door mounted to the home bar frame such that the home bar door can be hingedly rotated for opening and closing the opening, a coupling-and-releasing unit for coupling the home bar door to the home bar frame and releasing the home bar door from the home bar frame, and at least one hinge member having a rotary shaft movable in the inward and outward directions of the home bar door or the home bar frame such that the rotary shaft can be inserted into or separated from a hinge hole formed at the home bar frame or the home bar door.
摘要:
In a preparation method, a chiral or cholesteric liquid crystal, a photoreactive monomer, and a photoinitiator are disposed in a liquid crystal cell. A principal surface of the liquid crystal cell is illuminated with ultraviolet light selected to have a non-uniform ultraviolet light intensity profile in the liquid crystal cell. The illuminating cooperates with the photoinitiator to polymerize at least a portion of the photoreactive monomer near the principal surface to generate a polymer network having a density corresponding to the non-uniform ultraviolet light intensity profile. The polymer network biases the liquid crystal toward a selected helical alignment direction. In some embodiments, the illuminating includes illuminating with first and second ultraviolet light intensity profiles to produce surface and volume polymer network components.
