A thermoplastic polyurethane elastomer containing a very small amount of small grains, and having a high molecular weight and a narrow molecular-weight distribution. Such high-quality thermoplastic polyurethane is excellent in melt moldability and allows to prevent yarn breakage in producing fibers by melt spinning, for example. Such polyurethane elastomer can be produced by melt-polymerizing a prepolymer and a low-molecular diol at a relatively high temperature in a short period of time. This invention also provides an apparatus for producing the polyurethane elastomer, and fibers formed of said elastomer.

Disclosed is a method for producing a water absorbent resin, by which a surface-crosslinked water absorbent resin having excellent physical properties can be efficiently obtained at low cost, while assuring high productivity. When the production scale is increased to a continuous production at 1 t/hr or more, the physical properties are improved and stabilized (for example, standard deviation of the physical properties is reduced) by a surface-crosslinking treatment, and the absorption against pressure (AAP) and liquid permeability (SFC) are further improved. Specifically disclosed is a method for producing a water absorbent resin, which is characterized in that the stirring shaft of the continuous mixing apparatus for the surface-crosslinking agent is heated during the mixing step of the surface-crosslinking agent or that the continuous mixing apparatus for the surface-crosslinking agent is operated at a pressure that is reduced relative to the ambient pressure and a gas flow is passed through the mixing apparatus during the mixing of the surface-crosslinking agent so that the gas flow in the mixing apparatus is 40° C. or more (when defined with respect to the gas temperature at the exit).

A method of producing a particle-shape water-absorbing resin material is realized. With this method, it is possible to prevent deterioration of properties of the particle-shape water-absorbing resin material, and reduces damages onto surfaces thereof. This method is arranged such that (a) water-absorbing resin particles are surface-treated by using a crossing agent so that surfaces of the particles are cross-linked, (b) an additive for giving a function to the particles is added to the particles, (c) and a step of mixing the particles and the additive is carried out in a step of performing particle-size regulating treatment for the particles which includes agglomerated particles.

A coating apparatus includes a driving unit configured to rotate a substrate holding member about a vertical axis to spread a coating liquid supplied on a front side central portion of a substrate toward a front side peripheral portion of the substrate by a centrifugal force. The apparatus is provided with a wobble damping mechanism including a gas delivery port and a suction port both disposed to face a back side of the substrate and configured to damp a wobble of the substrate being rotated by delivering a gas from the delivery port and sucking the gas into the suction port.

To provide a lenticular lens sheet having a fine light shielding pattern that has high color reproducibility. [MEANS FOR SOLVING PROBLEMS] The above problem can be solved by a lenticular lens sheet, in which the average primary particle diameter of carbon black contained in a light shielding layer is not less than 10 nm and not more than 50 nm and, preferably, in an image of the cross-section of the light shielding layer under scanning electron microscopic observation, the area ratio of carbon black to the whole image is not less than 60% and not more than 95%, and a process for producing the lenticular lens sheet.

The hydrophobicizing apparatus includes a vaporizing surface forming member of which surface is located in a vaporizing room; a vaporizing surface heating unit that heats the vaporizing surface forming member; a liquid chemical supply port that supplies a liquid chemical for a hydrophobicizing process on the surface of the vaporizing surface forming member; a gas inlet port that introduces a carrier gas into the vaporizing room; an outlet port that supplies a hydrophobicizing gas vaporized in the vaporizing room; and a processing chamber that performs the hydrophobicizing process on a substrate accommodated therein by the hydrophobicizing gas supplied through the outlet port. With this configuration, the hydrophobicizing gas of a high concentration can be supplied onto the substrate. Further, since the stored liquid chemical is not in contact with the carrier gas when a process is not being performed, degradation of the liquid chemical is suppressed.

摘要:
A coating solution is sprayed on a rotating wafer held horizontally from a nozzle provided above the wafer while the nozzle is travelling over the wafer from a wafer center to a wafer outer area, thus spirally spraying the coating solution on the wafer. The nozzle stops when the coating solution has reached the wafer outer area and the coating solution is sprayed in circle on the wafer outer area while the wafer is rotating. A coating solution including a component of a coating film and a solvent may be sprayed on a first area to be coated of the wafer and the coating solution and a solvent for the coating film may be sprayed on a second edge area located outside the first area of the wafer.

A particulate water absorbent contains a water absorbent resin as a main component, the water absorbent resin being a crosslinked polymer of a water-soluble unsaturated monomer. The water absorbent resin is particular in shape and contains particles of a particle size in a range of not less than 106 μm and less than 850 μm in an amount of not less than 90 mass percent with respect to the total mass of the water absorbent resin contained in the particulate water absorbent. The particulate water absorbent has a first salt concentration absorption index of not less than 0.60 as measured by a formula below when ion exchange water is used as an aqueous solution of a constant salt concentration: (salt concentration absorption index)=(absorbency against a pressure of 4.83 kPa with respect to the aqueous solution of a constant salt concentration)/(absorbency against no pressure with respect to the aqueous solution of a constant salt concentration).
