Abstract: A delay locked loop having improved synchronization times has a variably adjustable delay line which accepts two incoming clock pulses. As each pulse propagates through the delay line an edge of the pulse toggles or retoggles a shift bit corresponding to a delay element. When the first pulse reaches the end of the delay line, the status of the shift bits is frozen, and a starting point for a synchronization sequence begins at the transition point between toggled and retoggled shift bits.

Abstract: A double pitched array includes isolation devices to divide the array into subarrays, using the same space which is used for bit line twists. This addition allows the one-fourth of the bit line pair which will not be used to propagate signals to not be charged during a memory operation.

Abstract: A centrifuge bucket is provided. The centrifuge bucket has a bucket body and a holder plate mounted within the body. The holder plate has a plurality of holder openings therein to receive samples. The centrifuge bucket has a bottom support member having a plurality of support openings. Each of the support openings is precisely aligned with a respective holder opening. An alignment post mechanism is affixed to the bucket. The alignment post mechanism has a mechanism base disposed on the bottom support member and an alignment post attached to the mechanism base.

Abstract: A rotor locator and centrifuge body locator includes a pair of locator arms that close about the rotor shaft and an alignment pin to center the rotor shaft. A registration mechanism rotates the rotor shaft and the centrifuge body until it reaches a known home position. A method of consistently registering the centrifuge body includes centering a rotor shaft of the body along a known center line and aligning the body to a home position both before and after centrifugation.

Abstract: Disclosed is a container capacitor structure and method of constructing it. An etch mask and etch are used to expose portions of an exterior surface of electrode (“bottom electrodes”) of the container capacitor structure. The etch provides a recess between proximal pairs of container capacitor structures, which recess is available for forming additional capacitance. Accordingly, a capacitor dielectric and a top electrode are formed on and adjacent to, respectively, both an interior surface and portions of the exterior surface of the first electrode. Advantageously, surface area common to both the first electrode and second electrodes is increased over using only the interior surface, which provides additional capacitance without a decrease in spacing for clearing portions of the capacitor dielectric and the second electrode away from a contact hole location.
