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. The partition divides an interior space of the chamber above the first main surface of the substrate into a first space upstream of the first jet opening with respect to the direction of substrate transport, and a second space downstream of the first jet opening with respect to the direction of substrate transport.

The present invention concerns a method and a device for curing a thermosetting polymer. The method comprises the steps of irradiating the thermosetting polymer with microwaves at a first power level so as to heat up the thermosetting polymer by dielectric heating, and when the thermosetting polymer reaches a first predetermined temperature, irradiating the thermosetting polymer with microwaves at a second power level, substantially higher than the first power level, to further heat up the thermosetting polymer by dielectric heating. The device comprises an enclosure for receiving the thermosetting polymer, a microwave emitter for emitting microwave radiation into the enclosure, and a control unit for controlling a microwave emission power of the microwave emitter according to the abovementioned method.

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. A mixed monomolecular film is formed 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, and then increasing the surface pressure of the mixed monomolecular film.

A protective layer (20) is formed in a picture frame shape and a thin film shape between an electrolyte membrane (1) and a peripheral edge portion of a catalyst layer (30) by applying ink by an ink jet method. The protective layer (20) is formed directly on the electrolyte membrane (1) to a thickness in the range of about 0.1 μm to 5.0 μm.
摘要:
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. A coating formulation—which comprises fine particles of a thermoplastic resin having both a property that the particles unite to the surface when heated and a property that the particles decompose under action of the photocatalyst when exposed to activating light having energy higher than band gap energy of the photocatalyst—is applied as a hydrophobizing agent onto the surface. At least a part of the surface of the precursor is heated such that the fine particles applied on the part of the surface are fixed to form a hydrophobic image area. The fine particles applied on the remaining part of the surface with the image area formed thereon are then removed.
