摘要:
A laminated shape-retainable sheet having a sufficient shape retainability for a user to be able to easily provide a specified shape thereto and capable of eliminating the need of a press working step for providing a curved shape thereto, a core for the brim of a headwear using the sheet, the brim of the headwear, and the headwear. The laminated shape-retainable sheet is formed by laminating and adhering shape-retainable sheets formed of a thermoplastic resin and having the shape retainability in one axial direction so that one axial direction of the shape-retainable sheets adjacent to each other can form a specified angle, desirably 45 to 90°.

This invention provides a blue phosphor, which has excellent durability and high brightness, particularly a blue phosphor powder which can realize high-brightness luminescence upon exposure to an electron beam. The phosphor is characterized in that the phosphor comprises at least europium dissolved in a solid solution form in an inorganic crystal having a crystal structure of an AlN crystal or an AlN solid solution crystal and, upon exposure to an excitation source, emits divalent europium-derived fluorescence having a peak at a wavelength in the range of 430 nm to 500 nm. In this case, the incorporation of a predetermined metal element and silicon is more preferred. There are also provided a production process of this phosphor and a lighting equipment comprising the blue phosphor.
摘要:
Disclosed is aramid tire cord and a method for manufacturing the same, wherein the aramid tire cord has superior properties on initial modulus change rate, tensile strain, initial modulus and strength retention rate, wherein the initial modulus change rate is not more than 5% after the aramid tire cord is repetitively extended 10 times at 120°C under the condition that the load corresponding to 10% of the strength at break is applied thereto. Thus, the aramid tire cord of the present invention has the most optimal modulus, optimal crystallization constant and optimal crystalline orientation constant so that the aramid tire cord is superior in its initial modulus change rate, tensile strain and initial modulus retention rate, to thereby obtain good fatigue resistance. Thus, if the aramid tire cord of the present invention is used for a tire-reinforcing material, it is possible to obtain high traveling performance by preventing the property deterioration during the high-speed traveling with repetitively-occurring sequence of high temperature and high pressure.
