  • Publication number: 20120073973
    Abstract: An anisotropically conductive member includes an insulating base having through micropores and conductive paths formed by filling the through micropores with a conductive material, insulated from one another, and extending through the insulating base in its thickness direction, one end of each of the conductive paths exposed on one side of the insulating base, the other end of each of the conductive paths exposed on the other side thereof. The insulating base is an anodized film obtained from an aluminum substrate and the aluminum substrate contains intermetallic compounds with an average circle equivalent diameter of up to 2 ?m at a density of up to 100 pcs/mm2. The anisotropically conductive member dramatically increases the density of disposed conductive paths and suppresses the formation of regions having no conductive paths, and can be used as an electrically connecting member or inspection connector for electronic components.

  • Publication number: 20110311800
    Abstract: A microstructure enabling provision of an anisotropic conductive member capable of reducing wiring defects and a method of producing such microstructure. The microstructure includes through-holes formed in an insulating matrix and filled with a metal and an insulating substance. The through-holes have a density of 1×106 to 1×1010 holes/mm2, a mean opening diameter of 10 nm to 5000 nm, and a mean depth of 10 ?m to 1000 ?m. The sealing ratio of the through-holes as attained by the metal alone is 80% or more, and the sealing ratio of the through-holes as attained by the metal and the insulating substance is 99% or more. The insulating substance is at least one kind selected from the group consisting of aluminum hydroxide, silicon dioxide, metal alkoxide, lithium chloride, titanium oxide, magnesium oxide, tantalum oxide, niobium oxide, and zirconium oxide.

  • Patent number: 7497987
    Abstract: A refining method and apparatus for decarburization refining of chromium containing molten steel in a vessel having a first step of blowing oxygen while the inside of the vessel is at a pressure of between 400 Torr and atmospheric pressure, a second step of blowing oxygen while evacuation the inside of the vessel to 250 to 400 Torr and a third step of blowing gas while evacuating the vessel to not more than 250 Torr. Further, a refining method and apparatus for ultra-low carbon chrome melt by performing a first vacuum refining until the third step, then restoring the pressure in the vessel to at least 400 Torr, then performing second vacuum refining while making the bottom blowing gas blow rate at least 0.4 Nm3 per to steel.

  • Patent number: 6923573
    Abstract: The invention provides a cooling system for protecting an image fiber and an imaging device from thermal influences and a temperature measurement apparatus, for a molten metal, capable of being easily controlled and stably measuring the temperature. The temperature measurement apparatus for a molten metal comprises four connectable portions of a nozzle portion a purge/cooling gas introduction portion, an image fiber fitting portion with a window glass and an image fiber to a double pipe nozzle protection tube. A distance from a nozzle distal end as an introduction portion of thermal radiation light to a light reception portion at an image fiber distal end becomes short so that a greater amount of thermal radiation light can be received.

  • Patent number: 4035193
    Abstract: A method and apparatus for calcining powdered material for cement manufacture by making good use of the sensible heat and fluidity of preheated material in the burning process and utilizing the material as a catalyst for diffusing and vaporizing fuel, thereby producing reducing gases, and then bringing the reducing gases into contact with the combustion gases from a kiln for stepwise combustion so that the cement material is decarbonated and the nitrogen oxide contents of the exhaust gases from the kiln are decreased.
