Abstract: A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture. A contaminate tank receives a supply of the fluid mixture containing contaminate from a source such as a manufacturing line where overspray of paints or cleaning solutions containing washed away oils are collected. A free floating weir floats on the surface of the contaminate tank and mechanically separates and removes contaminate from a surface of the contaminate tank and concentrates the contaminate in a consolidation tank. In the consolidation tanks the contaminate is further separated and collected for disposal.

Abstract: A test vector decode circuit includes a lockout circuit to prevent inadvertent latching of output vectors. The test vector decode circuit is driven by an additional output vector from the test vector decode circuit. The additional output vector, as well as the other output vectors, undergo at least one latching. The signal transmitted by the additional output vector as a result of the final latching activates the lockout circuit. The test vector decode circuit also receives a supervoltage signal. Only by turning off the supervoltage signal can all of the output test vectors be reset, including the additional output vector.

Abstract: A memory device including a circuit for actively driving a reference voltage in a memory device is disclosed. A circuit integrated in a memory device and coupled to an external voltage source substantially eliminates fluctuations in the reference voltage of the memory device caused by power supply changes and noise occurring in the memory device by generating a constant voltage and good current drive from the external voltage source.

Abstract: Circuits and methods are provided that reduce, if not prevent, the adverse effects of transient noise on phase adjustments made by digital delay lock loop (DLL) circuits, which typically generate a periodic output signal having a particular phase relationship with a periodic input signal. A digital low pass filter of a DLL circuit includes circuitry, such as, for example, a thermometer register, coupled to receive the outputs of a DLL phase detector. The low pass filter prevents the DLL circuit from making frequent changes to the phase of the DLL output signal.

Abstract: As part of a memory array, a circuit is provided for altering the drive applied to an access transistor that regulates electrical communication within the memory array. In one embodiment, the circuit is used to alter the drive applied to a sense amp's voltage-pulling transistor, thereby allowing modification of the voltage-pulling rate for components of the sense amp. A sample of test data is written to the memory array and read several times at varying drive rates in order to determine the sense amp's ability to accommodate external circuitry. In another embodiment, the circuit is used to alter the drive applied to a bleeder device that regulates communication between the digit lines of the memory array and its cell plate. Slowing said communication allows defects within the memory array to have a more pronounced effect and hence increases the chances of finding such defects during testing.

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.
