摘要:
An ore containing crystal water (bond water) is heated to dehydrate the crystal water in the form of water vapor, thereby rendering the ore porous to generate a porous ore. Next, the porous ore is forced into contact with a dry-distilled gas (organic gas) obtained by dry-distillation of an organic substance such as wood and the like or an organic liquid such as tar and the like. An organic compound such as tar and the like contained in the dry-distilled gas or organic liquid adheres to the surface of the porous ore. Next, the porous ore adhered with an organic compound is heated at 500° C. or higher, to generate an ore in which a part of an oxide of an element such as iron and the like contained is reduced by carbon in the organic compound.

An end of a built-in optical fiber of a ferrule is made with one end of the built-in optical fiber matched with a splicing end surface and other end of the built-in optical fiber protruded from an end portion opposite to the splicing end surface and one end of a splicing optical fiber to be spliced are placed is fusion-sliced with the one end of the splicing optical fiber. The ferrule is held by inserting a cylindrical portion of the ferrule into a holding unit of a ferrule holder from the splicing end surface. The ferrule is transferred while holding a stem extended on an opposite side of the holding unit of the ferrule holder and the splicing optical fiber.

An optical connector kit includes a ferrule-with-optical-fiber and an accommodating housing for accommodating all connector parts constituting an optical connector, including the ferrule-with-optical-fiber. An optical fiber having a predetermined length is attached to the ferrule of the ferrule-with-optical-fibers, for which end face polishing processing is carried out. The connector parts include a plurality of connector parts into which another optical fiber is inserted when the rear end of the optical fiber of the ferrule-with-optical-fiber and the tip end of another optical fiber are fusion-spliced. In the accommodating housing, the connector parts are arranged in a line in the order of insertion of another optical fiber.

There is provided a hydrogen production apparatus having a simple structure for efficiently producing hydrogen. The hydrogen production apparatus 10 comprises a reactor 12 for reacting silicon (which may be waste silicon) and an aqueous basic hydroxide solution, a hydrogen absorbing alloy 20 for storing hydrogen produced by the reaction, and a reservoir/filter 14 which retains a solid or liquid product generated in the reactor 12 and filters a solution or suspension containing the solid or liquid product so as to separate the product from water.

A built-in optical fiber of a ferrule has one end of the built-in optical fiber matched with a splicing end surface, and the other end of the built-in optical fiber protruded from an end portion opposite to the splicing end surface and one end of a splicing optical fiber to be spliced are placed so as to be fusion-sliced with one another. After that, the ferrule is held by inserting a cylindrical portion of the ferrule into a holding unit of a ferrule holder from the splicing end surface. The ferrule is transferred while holding a stem extended on an opposite side of the holding unit of the ferrule holder and the splicing optical fiber.

A first heat treatment is carried out in which a material powder comprising magnesium is kept in the atmosphere of hydrogen gas and the temperature and pressure in the atmosphere of hydrogen gas are maintained in the temperature-pressure region in which single Mg and H2 coexist in a thermodynamically stable state, whereby the coating on the surface of the material powder is removed. Next, a second heat treatment is carried out in which the temperature and pressure in the atmosphere of hydrogen gas are changed and maintained in the temperature-pressure region in which MgH2 exists in a thermodynamically stable state. Hence, Mg from which the coating is removed reacts promptly with H2, and MgH2 is produced at high yield. Magnesium-based hydrides containing high purity MgH2 can thus be obtained by supplying energy less than that required for the related art that requires an activation treatment.

An array antenna apparatus in which an SN ratio is improved. Antenna elements having transmission modules, respectively, are arranged in plurality, wherein the plurality of transmission modules respectively have transmission signal generators that each output a transmission intermediate frequency signal, local oscillation signal generators that each output a local oscillation signal, and transmission mixers that each mix the transmission intermediate frequency signal and the local oscillation signal with each other, thereby to carry out frequency conversion to a transmission high frequency signal. A reference signal source inputs a reference signal to the transmission signal generators and the local oscillation signal generators. The transmission intermediate frequency signal and the local oscillation signal are synchronized with each other by the reference signal.
