    摘要: In a rear combination lamp assembly for a vehicle, a plurality of LEDs capable of being turned on and off independently of each other are mounted on a first printed circuit board. A plate-like lens element and a second printed circuit board are arranged with the first printed circuit board located between them. A control circuitry is mounted on the second printed circuit board, for selectively turning on and off the LEDs to display various patterns on a matrix display formed by the LEDs. The first printed circuit board, the lens element and the second printed circuit board are held in a united fashion.

    摘要: An alkenylsuccinic acid emulsion sizing agent having a solid concentration of at least 30% by weight, which comprises an active component comprising:(1) from 70 to 95 parts by weight of an alkenylsuccinic acid obtained by reacting a branched internal olefin having 12 to 18 carbon atoms with maleic anhydride; and(2) from 5 to 30 parts by weight of an oxidized wax; andwherein the active component is dispersed in water using a high-molecular weight dispersion stabilizer or a mixed system of a high-molecular weight dispersion stabilizer with an emulsifier.
