Abstract: A humidifier is superior in terms of hygiene, simple in terms of maintenance, humidity is easily adjusted, and energy consumption is low. The humidifier uses, as a moisture permeable membrane, a moisture-permeable polyurethane obtained by using, as raw materials, at least an isocyanate component, a diol as a chain extender, and polyethylene glycol as a polyol component, and reacting these raw materials.

Abstract: Disclosed are a printing plate precursor, a fabrication process of the printing plate precursor, a fabrication process of a printing plate, a regeneration process of the printing plate, a printing press, and a coating formulation for the printing plate precursor. According to the present invention, a printing plate can be fabricated directly from digital data, and sufficient image quality can be obtained without a developing step, i.e., a developer. To permit repeated use of the precursor, the precursor has a surface, which contains a photocatalyst and is capable of showing hydrophilicity when exposed to activating light having energy higher than band gap energy of the photocatalyst.

Abstract: An object is to provide a nanostructure having a two dimensionally spread homogenous nanostructure, and a method of manufacturing a nanostructure that can be performed by a low cost and simple process. Another object is to provide a nanostructure having a homogenous nanostructure in a large area, and a method of manufacturing a nanostructure that can be performed by a low cost and simple process. A monomolecular film is obtained by spreading a mixed solution containing an amphipathic block copolymer which has hydrophilic segments and hydrophobic segments, and a low molecular weight compound which is compatible with the hydrophobic segments, on the surface of water.

Abstract: An apparatus for removing a treating liquid from main surfaces of a substrate that has undergone a wet surface treatment, includes a transport device for transporting the substrate, a first gas jetting device having a first jet opening for jetting a gas to a first main, upper surface of the substrate transported by the transport device, and a liquid removing chamber for preventing the treating liquid removed from the main surfaces of the substrate from scattering to ambient, the liquid removing chamber having a substrate inlet and a substrate outlet. A partition is mounted in the liquid removing chamber, with an upper end thereof contacting either an upper wall, a rear wall or a front wall of the liquid removing chamber. The partition extends between opposite side walls of the chamber parallel to direction of substrate transport.

Abstract: In bottom blown oxygen steel making or in top and bottom blown combined oxygen steel making, a tip end of a tuyer immersed in molten steel is seriously damaged or melted away due to very high temperatures due to the vigorous combustion of carbon, manganese and so on by the oxygen blown into a furnace.In order to prevent such damage, hydrocarbon gas has been blown through space between an outer pipe and an inner pipe of a dual pipe tuyere or tuyeres, but such hydrocarbon gas rather excessively lowers the temperature of the molten metal adjacent to the tip end of the tuyere and often blocks the opening of the tuyere.Now, instead of blowing in hydrocarbon gas, particulate material such as limestone magnesite, dolomite and the mixture thereof are proposed to be blown into the molten metal in the decarburization steel making vessel carried by an innert gas, combustion gas, blast furnace gas, LD process gas and oxygen or a mixture of these gases.
