摘要： PROBLEM TO BE SOLVED: To provide a discharge lighting fixture that has high safety without requiring complex manufacturing or machining processes and has excellent durability by setting the surface resistivity of a translucent member made of plastics to a predetermined value or less. SOLUTION: This discharge lighting fixture comprises a reflector 14, a high- intensity discharge lamp 10 placed near the focal point of the reflector 14, and a translucent member 12 made of plastics, which is pointed in the illuminating direction. In this case, the surface resistivity of the translucent member 12 is (n)×10 Ωor less ((n) is a number less than 10). When the translucent member 12 has a surface resistivity of (n)×10 Ω or less, it can prevent formation of white hazy patterns on the surface of the translucent member 12; preferably, it has a surface resistivity of (n)×10 Ω or less, or more preferably (n)×10 Ω or less so as to become most effective. In addition, the discharge lighting fixture is for use as a vehicular headlight and the translucent member 12 is made of a polycarbonate resin.

摘要： PURPOSE: To obtain an optical copolycarbonate resin composition which can stably give an optical molded article excellent in characteristics, e.g. reduced in optical distortion and excellent in transferability of pits, under a wide range of molding conditions. CONSTITUTION: This composition contains 100 pts.wt. copolycarbonate obtained by copolymerizing at least two aromatic dihydroxy compounds with a compound capable of introducing a carbonate bond and 0.01-0.1 pt.wt. polyhydric alcohol ester of an aliphatic carboxylic acid. The copolycarbonate contains constituent units derived from the aromatic dihydroxy compounds and represented by formulas I and II [wherein X and Y are each alkylene, cycloalkylene, -O-, -S-, -SO-or -SO2 - ; R , R , R and R are each a (halogen-substituted) 1-10C hydrocarbon group or halogen; m, n and p each stands for the number of substituents and are each an interger of 0 to 3; and R is H, a (halogen-substituted) 1-20C linear, branched or cyclic hydrocarbon group or halogen] at a molar ratio of 1: (8×10- to 1.5×10- ) and has a viscosity-average molecular weight of 12,000 to 18,000.

摘要： PROBLEM TO BE SOLVED: To obtain a resin compsn. which is excellent in stability, such as heat stability and color stability in molding in a molding machine by using a polymer having specific terminal structures. SOLUTION: This resin compsn. comprises 100 pts.wt. polymer and a polyhydric alcohol ester of an aliph. carboxylic acid pref. in an amt. of 0.01-0.1 pt.wt. The polymer has repeating units formed by reacting a dihydroxy compd. with a phosgene compd., a carbonic diester compd., or a dicarboxylic acid compd., and at least a part of terminal groups of the polymer are represented by formula I [wherein R and R are each a halogen or a monovalent hydrocarbon group; (p) is an integer of 0-3; (q) is an integer of 0-4; and X is a group represented by formula II (wherein R and R are each H or a monovalent hydrocarbon group; and R is a divalent hydrocarbon group) or a 6C or higher aliph., alicyclic, or arom. hydrocarbon group].
