  • Publication number: 20240132666
    Abstract: A polymer powder includes a polyamide, wherein a melting point determined in differential scanning calorimetry is 190° C. or higher, a difference between the melting point and a melting onset temperature, which is defined in differential scanning calorimetry as a lowest temperature among temperatures at each of which a first temperature differential value of Heat Flow (W/g) observed between a peak top temperature of an endothermic peak, observed when 10 mg of powder is heated at a rate of 20° C./min from 30° C. in a nitrogen atmosphere, and a temperature point of ?50° C. from the peak top, becomes ?0.2 (W/g.° C.), is less than 30° C., and a D50 particle size is 1 ?m or more and 100 ?m or less.

  • Patent number: 7407220
    Abstract: A vehicle front structure including: a closed-section cross member connected to a pair of front pillars; a closed-section hood ledge extending frontward from a portion of a corresponding one of the front pillars, where the cross member is connected to the corresponding one of the front pillars; and a strut housing provided on an inner side in a vehicle transverse direction of and adjacent to the hood ledge. The hood ledge is provided with two gussets dividing an internal space thereof into sections in the longitudinal direction of the hood ledge, and an intermediate portion of the hood ledge between the two gussets is located forward of the cross member and rearward of the strut housing.
