Abstract: A polyamide resin composition contains a polyamide resin and an inorganic filler. 90 mass % or more of polyamide 66 is contained relative to 100 mass % of the polyamide resin. The inorganic filler content is ?30 mass % relative to 100 mass % of the composition. The composition has a solidifying point of ?210° C. The composition has a spiral flow value of ?60 cm when the inorganic filler content is ?30 mass % and <40 mass %, ?40 cm when the content is ?40 mass % and ?50 mass %, and ?20 cm when the content is >50 mass % and ?70 mass %. The composition has a strain of ?3.8% in a 1000-hour tensile creep test under 120° C. and 60 MPa. The composition has a formic acid relative viscosity (VR) of 30<VR<40.

Abstract: A manufacturing method for a nanocrystal light emission substance having a nano structure crystal, doped with an activator and cured with ultraviolet light. The nanocrystal light emission substance is synthesized by a liquid phase co-precipitation process. During the liquid phase reaction, an organic acid, such as acrylic acid or methacrylic acid, is added. Alternatively, a high molecular organic acid, such as polyacrylic or polymethacrylic acid, polystyrene, is added after the liquid phase reaction. The resulting substance is then cured with ultraviolet light.
