摘要： An extender circuit provides a serial communication interface between an ATM layer and a PHY layer. The extender circuit includes a first circuit serially coupled to a second circuit. The first circuit is coupled to the ATM layer and communicates in parallel with the ATM layer. The first circuit is operable to receive a control signal from the ATM layer. The second circuit is coupled to the PHY layer and communicates in parallel with the PHY layer. The first circuit does not transmit the control signal to the second circuit. The second circuit regenerates the control signal at the PHY layer. The first circuit and the second circuit function in like manners. The first circuit receives a control signal generated by the ATM layer. The control signal may comprise a start of cell signal. The first circuit transmits a first sequence of signals to the second circuit. The second circuit detects the occurrence of the first sequence of signals and reproduces the control signal at the PHY layer when the first sequence of signals is not detected. The first sequence of signals may comprise an idle character. In another embodiment, the first circuit transmits a second sequence of signals to the second circuit. The second circuit reproduces the control signal at the PHY layer when the second circuit detects the first sequence of signals followed by the second sequence of signals.

摘要： Copper is recovered from an aqueous pulp of an ore containing both sulfide minerals and oxidized minerals by continuously monitoring the EMF of the pulp and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of contained sulfur per ton of ore whenever and for so long as the pump EMF is above about -30 millivolts with reference to a standard silver-silver chloride electrode, and discontinuing such addition whenever such EMF in less than about -30 millivolts. Thereafter the pulp is subjected to a froth flotation operation in the presence of a collector for copper sulfide minerals to produce a concentrate containing most of the sulfide minerals and a substantial part of the oxidized minerals of the ore.

摘要： The method of producing bromine-processed graphite fibers comprises preparing gas phase grown carbon fibers by bringing a substrate carrying thereon ultrafine particles of metal catalyst into contact with hydrocarbon compound under a high temperature, graphitizing the thus obtained fibers to obtain graphite fibers having such a crystal structure as carbon hexagonal network face is substantially in parallel with the axis of fibers and is oriented coaxially, and then bringing the thus obtained graphite fibers and bromine at a temperature lower than 60.degree. C. and for a time at least for 10 min.. In this case, the specific value for the length of the repeat distance along the c axis direction in the crystals is within a range from 10 to 40 .ANG..

摘要： In a laser machining system for the heat treatment of an object, a pair of cylindrical concave mirrors are used to receive a source laser beam and irradiate a linear laser beam on to the object. The system is further provided between the latter cylindrical mirror and the object with at least a pair of slant-type plane mirrors for conditioning the linear beam. The plane mirrors have means for variably making the lengthwise dimension of the output linear beam smaller than that of the incident linear beam, so that a linear laser beam of various lengthwise dimensions can be produced.
