摘要： In an imprint mold-forming synthetic quartz glass substrate (1) of rectangular shape having dimensions L1 and L2 with L1≥L2, a circular region is delineated on the substrate back surface by a circle of radius R with L2−2R≥10 mm. When approximation analysis is performed from the 1st to 8th term in the Zernike polynomials on the circular region, a coefficient of the 4th term is equal to or greater than −(2R/100,000×1) μm.

摘要： A manufacturing method of glass base material for optical fiber that can obtain glass base material for optical fiber with reduced fluctuation in optical properties in the longitudinal direction is provided. The manufacturing method includes: a first heat treatment step in which the porous glass base material inserted in a vessel of a sintering furnace is heated by a heater installed around the periphery of the vessel while being raised or lowered in the longitudinal direction in a chlorine-based gas containing atmosphere in the vessel of the sintering furnace; a second heat treatment step in which the porous glass base material is heated by the heater to obtain a transparent glass body while being raised or lowered in the longitudinal direction in an inert gas containing atmosphere in the vessel after the first heat treatment step; and a preliminary fluorine doping step prior to the second heat treatment step.

摘要： Room temperature-vulcanizing silane-containing resin compositions are described, containing: (A) 100 parts by mass of a silane-modified polybutadiene compound represented by formula (1) (B) 0.5 to 20 parts by mass of a hydrolyzable organosilane compound having in each molecule an average of at least two silicon atom-bonded hydrolyzable groups, and/or the partial hydrolysis condensate of this hydrolyzable organosilane compound; and (C) 0.1 to 10 parts by mass of a curing catalyst. This room temperature-vulcanizing silane-containing resin composition is suitable for application as a coating agent composition and in particular as, e.g., a coating agent for electrical and electronic components and substrates therefor, and a sealant for liquid crystal display elements. The room temperature-vulcanizing silane-containing resin composition provides a gas permeation-resistant coating film (cured material) and is useful as a coating agent that exhibits a corrosion-inhibiting capability versus corrosive gases.

摘要： A negative electrode active material for a non-aqueous electrolyte secondary battery contains negative electrode active material particles which include silicon compound (SiOx: 0.5≤x≤1.6) particles. The negative electrode active material particles are at least partially coated with a carbon material, contain one or more selected from Li2SiO3 and Li2Si2O5, and satisfy Ib/Ia≤4.8 and Ic/Ia≤6.0 in an X-ray diffraction measurement using a Cu-Kα line. Ia represents an intensity of a peak around 2θ=28.4° attributable to Si obtained by the X-ray diffraction. Ib represents a peak intensity of a peak attributable to Li2SiO3 obtained by the X-ray diffraction. Ic represents a peak intensity of a peak attributable to Li2Si2O5 obtained by the X-ray diffraction. Thus, a negative electrode active material for a non-aqueous electrolyte secondary battery, is stable over a long period even in an aqueous slurry and enables high capacity, favorable cycle characteristics and first-time efficiency.

摘要： A resist composition comprising an ammonium salt and fluorine-containing polymer offers a high sensitivity and is unsusceptible to nano-bridging, pattern collapse or residue formation, independent of whether it is of positive or negative tone. The ammonium salt and fluorine-containing polymer comprises repeat units AU having an ammonium salt structure containing a carboxylic acid anion, sulfonamide anion, phenoxide anion or enolate anion of β-diketone, the anion containing fluorine, but not iodine and bromine, and repeat units FU-1 having a trifluoromethylalcohol group and/or repeat units FU-2 having a fluorinated hydrocarbyl group.
