In manufacturing of a carboxyl group-containing water-soluble polymer by a precipitation polymerization method, a method which can improve production efficiency with increasing practicality continuously adds a monomer solution wherein a monomer component containing an α,β-unsaturated carboxylic acid is dissolved in an inert solvent in a concentration of 20 to 50% by volume to an inert solvent charged in a reaction vessel. In this case, the amount of the inert solvent charged in the reaction vessel is set so that the concentration of the monomer component in the total amount summed up with the monomer solution is 10 to 24% by volume, and the time period until completion of continuous addition of the total amount of the monomer solution is set so that the conversion of the monomer component at the time of completion of addition of the total amount of the monomer solution is 60% or more. The monomer component may contain a polymerizable compound having two or more ethylenically unsaturated groups.

An ultraviolet irradiation device includes a treatment vessel, an ultraviolet irradiation member, and a support member. The treatment vessel has a water inlet and a water outlet and through which water to be treated as a treatment target flows in a first direction from the water inlet toward the water outlet, the treatment vessel receiving the water to be treated through the water inlet and discharging the water to be treated through the water outlet. The ultraviolet irradiation member is provided inside the treatment vessel along a second direction crossing the first direction and which irradiates the water to be treated flowing through the treatment vessel with an ultraviolet ray. The support member is provided inside the treatment vessel along the second direction with both end portions of the support member being firmly fixed to wall surfaces of the treatment vessel.

An object of the present invention is to provide a method for easily producing granular carboxyl group-containing polymer particles that have a high bulk density and readily swell in water. The present invention provides a method for producing granular carboxyl group-containing polymer particles, which includes: producing carboxyl group-containing polymer particles; preparing an aggregate of the carboxyl group-containing polymer particles by allowing the carboxyl group-containing polymer particles to absorb an polar organic solvent to a liquid content of 5 to 25% by mass; and drying the aggregate of the carboxyl group-containing polymer particles and then grinding the dried aggregate.

A resist treatment unit for performing treatment on a resist film which has been formed on a substrate is disclosed. This resist treatment unit includes: a treatment container capable of maintaining a vacuum therein; a mounting table provided in the treatment container for mounting the substrate on which the resist film has been formed thereon; a gas supply part for jetting a mixture gas containing a first gas and a second gas which are chemically inert toward the mounting table at a predetermined flow rate; and an exhaust part capable of exhausting the treatment container to a degree of vacuum at which the mixture gas jetted from the gas supply part at the predetermined flow rate is able to be a molecular beam in the treatment container.

A thin film removing device and a thin film removing method are capable of removing straight parts of a thin film formed on a square substrate from corners of the substrate, and of suppressing the formation of mists. An approach stage 20 having flat stage plates 23 capable of being disposed substantially flush with the surface of a substrate M mounted on a support table 22 is positioned close to the substrate M mounted on the support table 22. Removing nozzles 30 jet a solvent toward edge parts of the substrate M and suck a solution produced by dissolving part of the resist in the solvent while the removing nozzles 30 are moved along side edges of the substrate M and the approach stage 20 disposed close to the substrate M. Thus, the removing nozzles 30 jet the solvent uniformly over the edge parts and corners of the substrate M and suck the solution without changing modes of jetting the solvent and sucking the solution. Consequently, straight parts of a thin film formed on the square substrate M can be removed from the corners of the substrate M, and the formation of mists can be suppressed.

An object of the present invention is to provide a water-soluble acrylate polymer that can form a gelling base. When used in forming a poultice or cooling sheet, the gelling base not only imparts desirable stretchability, but also has an appropriate reaction rate with a polyvalent metal. The gelling base is free from gel penetration to the back side of a support or gel seeping from the support while the gel is being cured, and is easily applied to the support. When the gelling base is gelated by being allowed to stand under the conditions of 25° C. and a relative humidity of 60%, the gel strength is 3,200 to 7,000 dyn/cm2 after standing for 7.5 hours and 5,000 to 9,000 dyn/cm2 after standing for 200 hours, and satisfies the following relationship: Gel strength after standing for 7.5 hours]≦Gel strength after standing for 200 hours.

A maintenance pattern forming method includes conveying, generating, and forming. The conveying conveys a transfer member on a surface of a conveying member such that there is a spacing area between two adjacent transfer members on the surface of the conveying member. The generating generates a timing signal for at least one of a plurality of colors formed by a color image forming apparatus. The forming forms at least one of a process control pattern, a position adjustment pattern, and a blade curl suppression pattern onto the spacing area based on the timing signal.
