摘要： An Fe—Cr—Si based non-oriented electrical steel sheet contains 2.5% to 10% by mass of Si, 1.5% to 20% by mass of Cr, 0.006% by mass or less of C, 0.002% by mass or less of N, 0.005% by mass or less of S, 0.005% by mass or less of Ti, 0.005% by mass or less of Nb, and as necessary, 0.1% to 2% by mass of Al and at least one of 0.005% to 1% by mass of Sb and 0.005% to 1% by mass of Sn, and the balance being Fe and incidental impurities, wherein the electrical resistivity of the steel is 60 μΩcm or more, and the number of nitrides containing chromium per mm2 in the interior of the steel sheet is 2,500 or less. Consequently, the problem that high electrical resistance resulting from the high Si content and high Cr content is not satisfactorily utilized is advantageously solved, and it is possible to provide a non-oriented electrical steel sheet having excellent magnetic properties in the high-frequency range, in particular, in a frequency range of 1 kHz or more.

摘要： A finish annealed non-oriented electromagnetic steel sheet includes about 0.01 wt % or less of C, greater than about 1.0 wt % and at most about 3.5 wt % of Si, at least about 0.6 wt % and at most about 3.0 wt % of Al, at least about 0.1 wt % and at most about 2.0 wt % of Mn, at least about 2 ppm and at most about 80 ppm of one or more rare earth metals (REM), a maximum content of Ti and Zr being about 15 ppm and 80 ppm, respectively, wherein oxygen on the surface layer of the steel sheet is 1.0 g/e2 or less. Since the non-oriented electromagnetic steel sheet has desirable mechanical properties resulting from the increased amounts of Si and Al, a high magnetic flux density can be maintained without sacrificing a punching property as well as very low iron loss can be obtained even after stress relief annealing.

摘要： A synchronizing signal extracting apparatus comprising synchronizing signal detecting circuit for detecting a synchronizing signal of predetermined bits from entered digital data, synchronizing signal generating circuit adapted to be reset by an output of the synchronizing signal detecting circuit, the synchronizing signal generating circuit generating an output in a timing of said synchronizing signal, and synchronizing signal extracting circuit for outputting, as a synchronizing signal, a result of an OR operation performed on the output of said synchronizing signal detecting circuit and the output of said synchronizing signal generating circuit, the synchronizing signal extracting circuit changing a state thereof according to match/mismatch in timing between the output of said synchronizing signal detecting circuit and the output of said synchronizing signal generating circuit. The novel setup outputs correct synchronizing signals and data enable signal even if the detection of synchronizing signals is missed or erroneously made, reduces chances of the missed detection of synchronizing signals even when the signal-to-noise ratio of reproduced signal is poor at digital VTR variable-speed reproduction or high-speed search, and implements synchronizing signal extraction of high precision.
