摘要:
A pulsed circuit topology including a pulsed domino flip-flop. A circuit includes a domino logic gate having a domino output node responsive to input data during an evaluate pulse. Reset circuitry initiates and self-terminates a reset pulse during which the domino output node is precharged. A latch responsive to a first pulsed clock input signal is provided to latch data indicated at the domino output node.

A pulsed circuit topology to perform a memory array write operation. A write enable pulse width control circuit is responsive to a pulsed clock signal to generate a pulsed write enable signal and a write data path circuit is provided to output a write data signal. The write enable pulse width control circuit and the write data path circuit together control a write operation to a memory cell.
摘要:
A reset first latching mechanism comprises a pulse chopper circuit responsive to a pulsed signal to control initiation and termination of a reset pulse wherein a domino node is to be precharged in response to the reset pulse. The reset first latching mechanism also includes domino logic circuit responsive to an evaluate pulse at an input to evaluate at the domino node based on a logic function performed by the domino logic circuit. The reset pulse is timed such that the reset pulse is completed before the evaluate at the domino node occurs.

Previous methods of bucksawing logs slow the throughput of a sawmill in that the conveyor line is stopped while a given log is bucksawed to length. The present invention provides a method for bucksawing a log which improves the throughput speed, comprising the steps of a) advancing the log endwise along an infeed conveyor; b) raising the log above the level of said infeed conveyor while advancing the log; c) measuring the advance of the log while raised; d) stopping the log at the desired length; e) sawing the log to produce a forward log segment; and f) lowering the forward log segment onto an outfeed conveyor while advancing the remaining log segments. An apparatus for carrying out the method is also disclosed.
