摘要： A wire-drawing optical fiber base material manufacturing method of heating an optical fiber base material by a heater and forming a drawing shape portion at an end portion. The manufacturing method includes: forming, by a flow-regulating member disposed adjacent to the heater, a gas flow such that formation, along a surface of the optical fiber base material, of a flow of a gas containing a Si compound generated from the optical fiber base material heated by the heater is inhibited; and forming, while maintaining the gas flow, the drawing shape portion by pulling part of the optical fiber base material softened by being heated by the heater.

摘要： Provided is a pellicle that can reduce residues stuck onto an exposure original plate when the pellicle is peeled from the exposure original plate after being used in lithography, in particular ArF lithography, and also provided are an exposure original plate with a pellicle, a method for regenerating an exposure original plate, and a peeling residue reduction method.
A pellicle includes a pellicle film, a pellicle frame provided with the pellicle film on one end face thereof, and an agglutinant layer provided on the other end face of the pellicle frame. When the agglutinant layer of the pellicle is bonded to a quartz mask substrate, then a portion to which the agglutinant layer of the pellicle is bonded is irradiated with 193-nm ultraviolet rays at 10 J/cm2 from a back surface of the substrate, and the pellicle is peeled after the irradiation, an amount of peeling residues of the agglutinant layer remaining on the substrate is 0.5 mg or less.-

摘要： A release agent composition for tire-molding contains: (A) 100 parts by mass of an organopolysiloxane containing at least two hydroxy groups bonded to a silicon atom in one molecule and having a viscosity at 25° C. of 10,000 mPa·s or higher; (B) 10 to 100 parts by mass of an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to a silicon atom in one molecule relative to 100 parts by mass of the component (A); (C) 10 to 10,000 parts by mass of water relative to 100 parts by mass of the component (A); and (D) 2 to 70 parts by mass of a polyvinyl alcohol relative to 100 parts by mass of the component (A). The release agent composition for tire-molding is excellent in release. Molding and vulcanizing tires repeatedly in succession a larger number of times without applying a release agent after once applying a release agent is realized.

摘要： A (meth)acryloyloxy-containing organosilicon compound (3) is prepared by simultaneously feeding a hydrohalosilane compound (1) and a (meth)acrylate compound (2) in the presence of a polymerization inhibitor to a reaction system, and effecting hydrosilylation reaction in the presence of a platinum catalyst. The content of (meth)acrylate compound (2) is 0-100 mol % based on the content of organosilicon compound (3) in the reaction system. R1 is a C1-C10 monovalent hydrocarbon group, X is halogen, n is 1, 2 or 3, R2 is H or methyl, and R3 is a C1-C18 alkylene group.
