    • A method of manufacturing steel sheets by applying continuous annealing after applying hot rolling or hot rolling and cold rolling by a customary method to steel material, containing less than 0.007% of C, less than 0.1% of Si, from 0.05 to 0.50% of Mn, less than 0.10% of P, less than 0.015% of S, from 0.005 to 0.05% of sol.Al and less than 0.006% of N, further, containing Ti and/or Nb added solely or in combination within such a range that the relationship of the effective amount of Ti (referred to as Ti*) and the amount of Nb in accordance with the following formula (1) with the amount of C can satisfy the following formula (2):Ti*(%)=total Ti(%)-((48/32).times.S(%)+(48/14).times.N(%)) (1)1.ltoreq.(Ti*/48+Nb/93)/(C/12).ltoreq.4.5 (2)if necessary, further containing from 0.0001 to 0.0030% of B and the balance of Fe and inevitable impurities, wherein continuous carburization and/or nitriding is applied, simultaneously, with the annealing such that the amount of solid-solute C and/or the amount of solid-solute N in the steel sheet is from 2 to 30 ppm. Steel sheets having excellent resistance to the cold-work embrittlement or provided with the BH property can be produced without deteriorating properties required for steel sheets, in particular, formability.

    • Two original images to be recorded are prepared as data (S10). A plurality of unit regions, each having an adequate area to record interference fringes of visible light, are defined and positioned on a hologram recording surface (S20). A gradation pattern, with which appearance probabilities of two record attributes gradually change in space, is overlapped onto the recording surface, and to each unit region, one of either record attributes is assigned according to the appearance probabilities of the respective record attributes at each individual position (S30). In each unit region, to which the first record attribute is assigned, the first original image is recorded as an interference fringe pattern, a diffraction grating pattern, or a scattering structure pattern, and in each unit region, to which the second record attribute is assigned, the second original image is recorded as an interference fringe pattern, a diffraction grating pattern, or a scattering structure pattern (S40), and a record pattern is formed on a physical medium (S50).
    • 准备要记录的两个原始图像作为数据(S10)。 定义并定位在全息记录表面上的多个单位区域,每个区域具有足够的面积来记录可见光的干涉条纹(S20)。 将两个记录属性的外观概率在空间中逐渐变化的渐变图案重叠在记录表面上,并且对于每个单位区域,根据每个个体的各个记录属性的外观概率来分配记录属性之一 位置(S30)。 在分配了第一记录属性的每个单位区域中,第一原始图像被记录为干涉条纹图案,衍射光栅图案或散射结构图案,并且在每个单位区域中,第二记录属性为 将第二原始图像记录为干涉条纹图案,衍射光栅图案或散射结构图案(S40),并且在物理介质上形成记录图案(S50)。
