An ion generation device includes a chamber in which plasma is generated, a first opening for introducing gas to be ionized by the plasma, and a second opening for irradiating ions generated from the gas. The inner wall of the chamber is coated with metal which is resistant to chemical etching by the ions and radicals.

Disclosed is a carbon nano-tube dispersant comprising a highly branched polymer having a repeating unit represented by, for example, formula (12) or (13), wherein the highly branched polymer is produced by the polycondensation of a triarylamine compound and an aldehyde compound and/or a ketone compound in the presence of an acid catalyst. The carbon nano-tube dispersant enables the dispersion of CNTs in a medium such as an organic solvent until the CNTs are so decomposed as to have an individual size. (In the formula, Z1 and Z2 independently represent a hydrogen atom, a phenyl group, a thienyl group, or the like.)
摘要:
A highly branched polymer comprising repeating units which each have an acid group such as sulfo group, said repeating units being represented by formula [1] or the like, and a dispersant for carbon nanotubes (CNTs) which comprises the highly branched polymer can disperse CNTs in a medium such as an organic solvent to the individual sizes and can yield thin films having improved conductivity. In formula [1], any one of A1 to A5 is a sulfo group, and the others are each a hydrogen atom.

To provide a tomato juice-containing alcoholic drink that has improved flavor qualities and shows regulated sedimentation and color change and a method of the production of the same. Provided is a method of the production of a tomato juice-containing alcoholic drink that comprises the following steps (a) to (c): (a) a step of producing a lactic acid-fermented tomato liquid that comprises fermenting a tomato juice-containing liquid by using a lactic acid bacterium and thus increasing lactic acid in the liquid; (b) a step of producing a clear tomato juice that comprises enzymatically treating a tomato juice and filtering the same; and (c) a step of mixing the lactic acid-fermented tomato liquid, the clear tomato juice and an alcohol; optionally followed, if desired, by the following step (d), (d) a step of adding stabilized lycopene.

A HDD includes a disk unit, a circuit board and an air intake and exhaust mechanism. In the disk unit, a magnetic disk is rotatably provided. The circuit board is provided with a driving circuit including electronic components. The air intake and exhaust mechanism includes a bag provided between the disk unit and the circuit board. The bag includes a communication hole airtightly communicating with an air intake and exhaust hole provided in a housing of the disk unit, and air intake and exhaust valves are provided at the bag, and located apart from the communication hole. Due to this structure, when the internal air pressure of the disk unit changes, gas flows into and out from the gap between the disk unit and the bag through the communication hole, thus restricting changing of the air pressure.

摘要:
A method for producing an electrode catalyst substrate is provided herein, which comprises a carbon film forming step of forming a porous carbon film on a base, a hydrophilization step of hydrophilizing the porous carbon film, an immersion step of immersing the base in a solution prepared by dissolving catalytic metal ions in a polar solvent, and a reduction step of adding a reducing agent to the solution and thus reducing the catalytic metal ions. An electrode catalyst substrate obtained by the method and a polymer electrolyte fuel cell in which the electrode catalyst obtained by the method is used for anodes and/or cathodes are also provided herein. In the electrode catalyst of the present invention, fine catalyst particles are loaded in a uniform and highly dispersed manner.
