  • Patent number: 11447848
    Abstract: A steel sheet wherein a steel structure of an inside of the steel sheet contains, by volume fraction, soft ferrite: 0% to 30%, retained austenite: 3% to 40%, fresh martensite: 0% to 30%, a sum of pearlite and cementite: 0% to 10%, and a remainder including hard ferrite. In the steel sheet, in a ? to ? thickness range, a proportion of retained austenite having an aspect ratio of 2.0 or more is 50% or more, and a soft layer having a thickness of 1 to 100 ?m from a surface in a sheet thickness direction is present. When an emission intensity at a wavelength indicating Si is analyzed in the sheet thickness direction from the surface by a radio-frequency glow discharge analysis method, a peak of the emission intensity appears in a range of more than 0.2 ?m and 5.0 ?m or less from the surface.

  • Patent number: 11437542
    Abstract: A method of manufacturing a light-emitting element includes condensing a laser beam inside a substrate provided with a semiconductor structure to form modified portions including first and second modified portions, including scanning the substrate along a predetermined planned cleavage line to form the first modified portions on the planned cleavage line inside the substrate and cracks generated from the first modified portions, and then scanning the substrate with a laser beam along a first predetermined imaginary line parallel to the planned cleavage line in a top view and is offset from the planned cleavage line in an in-plane direction of the substrate by a predetermined distance to perform second irradiation to form the second modified portions on the first predetermined imaginary line inside the substrate to facilitate development of the cracks generated from the first modified portions. The method then includes cleaving the substrate starting from the first modified portions.

  • Publication number: 20220276011
    Abstract: A heat conducting sheet has an overall sheet structure with a plurality of heat conducting regions. Each heat conducting region is continuous between the two primary surfaces of the heat conducting sheet, and connecting regions connect adjacent side-walls of the plurality of heat conducting regions stacked laterally between the primary surfaces. The heat conducting regions include vacancies. The connecting regions consist of material that includes flexible resin material and unfilled layers are formed in part of the connecting regions. Some of the resin material can ingress into part of heat conducting region vacancies. This structure can achieve a highly elastic and flexible heat conducting sheet due to vacancies in the heat conducting regions and unfilled layers in the connecting region.
