  • Patent number: 8985315
    Abstract: A loading member includes a receiving section that changes a posture thereof from a receiving posture where a loading material is received to a rising posture where the loading material is supported in a raised state; and a positioning section that is projected from a portion of a base end of the receiving section and then positions a lower end position of the loading material when the posture of the receiving section is changed to the rising posture; wherein the positioning section is provided with a loading assisting member assists the positioning of the loading material in a case of the receiving posture, while the front end of the loading assisting member rotates in a direction to approach a receiving surface of the loading material at the receiving section in a case of changing from the receiving posture to the rising posture.

  • Patent number: 8262818
    Abstract: A high strength steel sheet excellent in formability which has a chemical composition in mass %: C: 0.03 to 0.20%, Si: 0.005 to 0.3%, Mn: 1.0 to 3.1%, P: 0.001 to 0.06%, S: 0.001 to 0.01%, N: 0.0005 to 0.01%, Al: 0.2 to 1.2%, Mo?0.5%, and the balance: Fe and inevitable impurities, with the proviso that the values of mass % for Si and Al satisfy the following formula (1): (0.0012×[objective value of TS]?0.29?[Si])/2.45<Al<1.5?3×[Si]??(1) wherein [objective value of TS] represents a design strength value for the steel sheet in an Mpa unit, and has a metal structure containing ferrite and martensite. The above high strength steel sheet is also excellent in formability and the capability of being chemically treated and that of being hot-dip zinc sheeted.
