  • Publication number: 20240136096
    Abstract: A soft magnetic iron alloy sheet has a saturation magnetic flux density comparable to that of Permendur, with the same iron loss as electromagnetic pure iron, and a lower cost than Permendur. The soft magnetic iron alloy sheet includes, as a chemical composition, 30 at % or less of Co, 0.1 at % or more and 11 at % or less of N, and 1.2 at % or less of vanadium, with the remainder being Fe and impurities. In a thickness direction of the soft magnetic iron alloy sheet, a surface layer region has an average nitrogen concentration of 1 at % or more and 15 at % or less and an internal region has a lower average nitrogen concentration than the surface layer region. In the surface layer region, a thickness is 1% or more and 30% or less from both main surfaces of the sheet and iron-nitride martensite having a tetragonal structure is formed.

  • Patent number: 9645451
    Abstract: A liquid crystal display device using a liquid crystal exhibiting a blue phase and having a novel structure, and a method for manufacturing the liquid crystal display device. A plurality of structure bodies (also referred to as ribs, protrusions, or projecting portions) are formed over the same substrate, and a pixel electrode and an electrode (a common electrode at a fixed potential) corresponding to the pixel electrode are formed thereover. An electric field is applied to the liquid crystal layer exhibiting a blue phase by using the pixel electrode that has an inclination and the electrode corresponding to the pixel electrode, which also has an inclination. A shorter distance between the adjacent structure bodies allows a strong electric field to be applied to the liquid crystal layer, which results in a reduction in power consumption for driving the liquid crystal.
