  • Publication number: 20240100789
    Abstract: A method for manufacturing a photochromic lens includes: a step of injecting a polymerizable composition through an injection part in an injection molding apparatus and filling a gap with the polymerizable composition through a space; a step of heating the filled polymerizable composition to be polymerized and cured and forming a photochromic layer on a resin substrate; and a step of taking out a resulting laminate composed of the resin substrate and the photochromic layer, in which the polymerizable composition includes an isocyanate compound, a thiol compound, a polyol compound, and a photochromic compound.

  • Publication number: 20240083407
    Abstract: An oil dilution inhibiting apparatus is configured to inhibit oil dilution caused by mixture of fuel into engine oil. The oil dilution inhibiting apparatus includes a control unit. The control unit is configured to estimate friction of an engine and determine that the oil dilution occurs when the friction of the engine is decreased to a value lower than or equal to a predetermined threshold value to perform control so that the engine is operated at a higher speed.

  • Patent number: 11542201
    Abstract: There is provided at least any of a layered body which has a change in color tone and in which it is unnecessary to select a colorant and the content of the colorant in consideration of a difference in the sintering behavior between layers, a precursor thereof, or a method for producing these. Provided is a layered body which has a structure, in which two or more layers containing stabilizer-containing zirconia and a colorant are layered, and in which types and contents of the colorants contained in the layers are equal to each other, the layered body including at least: a first layer containing a colorant and zirconia which has a stabilizer content of higher than or equal to 3.3 mol %; and a second layer containing a colorant and zirconia which has a stabilizer content different from that of the zirconia contained in the first layer.

  • Patent number: 9889436
    Abstract: The chabazite-type zeolite of the present invention has a SiO2/Al2O3 molar ratio of less than 15, and an average particle size from 1.0 ?m to 8.0 ?m. The chabazite-type zeolite of the present invention has excellent durability and heat resistance, and the copper-loaded chabazite-type zeolite has an improved NOx reduction rate at low temperatures compared to conventional copper-loaded chabazite-type zeolite.

  • Patent number: 8795626
    Abstract: A chabazite-type zeolite having copper and an alkali earth metal supported thereon. The alkali earth metal is preferably at least one metal selected from the group consisting of calcium, magnesium and barium. Moreover, the SiO2/Al2O3 molar ratio is preferably from 10 to 50, and the copper/aluminum atomic ratio is preferably from 0.15 to 0.25. This type of chabazite-type zeolite exhibits a higher nitrogen oxide purification rate after a hydrothermal durability treatment than those of conventional chabazite-type zeolite catalysts on which only copper is supported.
