摘要： A circuit for generating a plurality of timing signals includes a plurality of cascade-connected delay cells, each having an input coupled to an output of another, and a plurality of latches. Set inputs of various latches are coupled to outputs of various delay cells to determine times of occurrence of leading edges of various timing pulses. Reset inputs of the various latches are coupled to outputs of various delay cells to determine times of occurrence of trailing edges of various timing pulses. The circuit includes a phase detector having a first input coupled to receive a clock signal and a second input coupled to an output of one of the delay cells to receive a signal indicative of propagation of a logic state through a first group of the delay cells, to produce an adjustment signal indicative of whether the phase of the indicator signal is ahead of or behind the phase of the clock signal. Each of the delay cells increases or decreases propagation time through that delay cell in response to the adjustment signal, so as to cause a time required for the logic state to propagate through all of the delay cells to be equal to a period of the clock signal.

摘要： High speed conversion of an analog input signal to a digital output signal is performed by applying the analog input to an input of a unity gain amplifier. During a first pass, an output signal produced by the amplifier is applied to inputs of each of a plurality of comparators. A first group of successively larger reference voltages are applied to reference inputs of the comparators, respectively. A plurality of the comparators switch in response thereto to produce output signals indicative of a range within which the output of the amplifier lies. The outputs of the comparators are encoded to effectuate conversion thereof to an analog representation of the amplifier output. The analog representation is compared to the analog input signal and the difference therebetween is applied to the input of the amplifier. During another pass another group of reference voltages, each substantially lower than corresponding values thereof during the previous pass, are applied to the reference inputs of the comparators. Binary representations of the outputs of the comparators during each of the passes are combined into a binary word accurately representing the analog input signal.

摘要： A method and an improved eductor apparatus for producing ultrafine explosive particles is disclosed. The explosive particles, which when incorporated into a binder system, have the ability to propagate in thin sheets, and have very low impact sensitivity and very high propagation sensitivity. A stream of a solution of the explosive dissolved in a solvent is thoroughly mixed with a stream of an inert nonsolvent by obtaining nonlaminar flow of the streams by applying pressure against the flow of the nonsolvent stream, to thereby diverge the stream as it contacts the explosive solution, and violently agitating the combined stream to rapidly precipitate the explosive particles from the solution in the form of generally spheroidal, ultrafine particles. The two streams are injected coaxially through continuous, concentric orifices of a nozzle into a mixing chamber. Preferably, the nonsolvent stream is injected centrally of the explosive solution stream. The explosive solution stream is injected downstream of and surrounds the nonsolvent solution stream for a substantial distance prior to being ejected into the mixing chamber.

摘要： A control method and apparatus for a metal-forming machine such as a cold heading machine are described. The described method and apparatus monitor machine operation during production and permit relatively large deviations from a prescribed norm over a short term without shutting down the machine, while ensuring longer term compliance to relatively small tolerances from the norm. The described controller first determines an average of a measured parameter such as the hit energy applied to a group of workpieces resulting in acceptable metal-forming during a training mode and then stores this average as a target value. The controller then establishes a set of tolerance windows to be used to control forming operations in a production mode.In production, the controller repeatedly measures the machine parameter and then compares selected averages of the measured parameter with the target value and the respective tolerance window, and indicates out-of-tolerance condition whenever one of the selected average falls outside the respective window. The tolerance windows are selected such that short term averages or single values of the measured parameter must deviate from the target values by larger amounts than long term averages before the controller signals an out-of-tolerance condition. For example, the described controller operates to interrupt machine operation when a single measured value of hit energy deviates by more than 16% from the learned target value, when a group of 4 measured values of hit energy deviates by more than 8%, when a group of 16 measured values of hit energy deviates by more than 4%, or when a group of 64 measured values of hit energy deviates by more than 1%.The disclosed controller also signals when the measured parameter is nearing an out-of-tolerance condition, and it acts to change the target value gradually during a warmup period of machine operation in order to reduce the number of unnecessary interruptions of machine operation.

摘要： The present invention provides a method for tiling an integrated circuit having a critically matched device such as a transistor. The method obtains an advantage of automatically improving metallic density over critically matched devices thus yielding improved CMP. The method may include the steps of: identifying critically matched devices in the integrated circuit; placing metal tiles over the critically matched device; performing a density test around each critically matched device; and if a density test is not satisfied around a critically matched device, placing at least one metal strip over a critically matched device.
