    Abstract: A process for separating a feed mixture comprising at least one aromatic hydrocarbon and at least one non-aromatic hydrocarbon by extractive distillation (ED) utilizing a solvent mixture comprising sulfolane and at least one co-solvent. The co-solvent is an alkyl sulfolane having from 4 to 8 carbon atoms per molecule. The solvent mixture is added to the top of the ED column, and the feed mixture is added at a point on the ED column that is lower than the point where the solvent mixture is added. Extractive distillation is performed, and the aromatic and non-aromatic hydrocarbons are separated.

    Abstract: A simply structured bi-functional roller skate has a pair of shoe embodiments. Each shoe embodiment is provided with a front securing seat which is a tubular device with a forwardly extended board, and a rear securing seat which is a tubular device with a backwardly extended board. Both the front and rear securing seats are embedded at the front end and the rear end of each shoe embodiment respectively. Each tubular device of the front and rear securing seats is in alignment with an engagement hole so as to permit a first and a second wheel axle each having a proper length to be led therethrough at the front and rear end of a shoe embodiment. Each wheel axle has a knob-ended locking screw at one end and an internally threaded section at the other end so as to permit the knob ended locking screw to be secured to the end of each wheel axle after roller wheels are mounted to the wheel axles respectively. The brake block has a threaded rod so as to make the brake block engage internally threaded holes defined at the front and rear securing seats respectively.

    Abstract: The present invention provides a method for forming capacitor of a dynamic random access memory cell. The method comprises providing a substrate and the word line structures formed thereon. A first dielectric layer is deposited on the substrate and the word line structures. A first polysilicon layer is deposited to form bit line contacts and bit lines. A second dielectric layer is formed on the first dielectric layer and the bit lines. The partial second dielectric layer is removed to form at least a wall structure in the second dielectric layer. The partial second dielectric layer and partial first dielectric layer are removed to form a capacitor contact opening. A second polysilicon is deposited into the capacitor contact opening and on the wall structure and the second dielectric layer. The partial second polysilicon is removed to form a capacitor node whereby a side-wall of the capacitor node is adjacent to the wall structure.

    Abstract: A voltage-controlled oscillator comprising a voltage compensation transistor is disclosed. The voltage compensation transistor is able to provide an equivalent resistance to the bias voltage supplied to the oscillator. When a sudden raise in the voltage of the power supply takes place, the equivalent resistance of the compensation transistor will drop, such that the bias voltage supplied to the oscillator may be pulled down, whereby the oscillation frequency of the ring oscillator may be adjusted.
