Abstract: This invention relates to rapid set, medium set, and
slow set anionic emulsions prepared from straight bitumen
or bitumen modified by the incorporation of polymers,
solvents, or polymer latices. Particularly, the
invention relates to improved methods for enhancing
adhesion between the asphalt and the aggregate in anionic
solventless and solvent-containing bituminous emulsions
wherein the emulsifiers are alkali earth salts of tall
oil fatty acids, fortified tall oil fatty acids, tall oil
rosin and fortified rosin as well as combinations of
kraft liqnin and nonionic emulsifiers. The adhesion
promoters utilized in these improved methods are the
reaction products of styrene (α-methyl styrene)-acrylic
(metacrylic) acid polymers with polyalkylene amines.
Further improvement can be obtained by using tall oil
fatty acid or fortified tall oil fatty acids as co-reactants
in the production of the polyamidoamine
products.

Abstract: In integrierten Schaltungen werden sogenannte Kondensatoren (switched capacitors; SC) beispielsweise zum Simulieren ohm'scher Widerstände verwendet. Hierzu wird der eine Belag des zu schaltenden Kondensators mit dem Eingangssignal über einen Transistorschalter (T1) gespeist, der an seinem Gate (G) als Steuersignal einen Impulszug mit vorbestimmter Frequenz empfängt. Um die parasitäre Kapazität des Transistorschalters zu kompensieren, liegt zwischen dem Transistorschalter und dem zu schaltenden Kondensator ein Kompensationsbauelement. Dieses ist als unvollständige Transistorstruktur (1/2-Transistor) ausgebildet, hat eine Drainzone (10) mit dem Transistorschalter (T1) gemeinsam und besitzt ein isoliertes Gate (18, 28). Damit ist die parasitäre Kapazität des Kompensationsbauelements hauptsächlich gegeben durch die Kapazität zwischen dem isolierten Gate (18, 28) und der Drain-Zone (10) und entspricht mithin der parasitären Kapazität (Cgd) des Transistorschalters (T1), wodurch eine vollständige Kompensation bei optimiertem Ladungstransfer erreicht wird. <IMAGE>
