Patent JP-S62175913-A (JP)
Title: Magnetic recording and reproducing system
Inventor: TAKAGI HITOSHI
IPC: G11B5/09
Filed: 1986-01-28
Abstract: PURPOSE:To obtain reproduction with a high accuracy by providing a modula tion circuit for making an inversion of a single recording current correspond to a bit '1' of an NRZI signal, and making an inversion of two recording currents of a double frequency correspond to a bit '0', and providing a differenti ation circuit on an outputting circuit of a reproducing amplifier. CONSTITUTION:For instance, when an NRZi signal (a) is '1, 0, 0, 1, 1, 0, 1' in a period of a bit cell T, it is modulated by a modulation circuit 8, and a recording current becomes as shown in (b). That is '1' of a bit cell T-0 becomes I-0 of the same cycle, and '0' of bit cells T-1 and T-2 becomes 1/2 cycle, namely, as I-1 and I-2 of a double frequency. An output waveform which has read a recording medium 3 recorded by the recording current (b), by a yoke MR head 4 becomes a figure (c), and when this waveform is amplified by a reproducing amplifier 5, and differentiated once by a differentiation circuit 9, a differential output (d) is obtained. When the differential output (d) is detected by a zero crossing detector 7, a zero crossing detecting pulse (e) is obtained. That is, a demodulated data (f) is obtained.

Title: Method and device for pattern discrimination
Inventor: YAMAMOTO MASAFUMI
IPC: G06T1/00
Filed: 1995-02-03
Abstract: PURPOSE: To shorten the processing time and discriminate even a slanting pattern by generating a midpoint weighted graph, comparing a figure obtained by normalizing it with a reference figure, and discriminating the pattern of an original figure. CONSTITUTION: A pattern discriminating processing part 7 finds the intersections of an input line drawing obtained by a thin-line processing part 6 and horizontal scanning lines y=n to generate a midpoint figure m1 between the intersections. A weighted graph is generated taking the length of the midpoint figure m1 in the direction crossing the scanning direction as the axis of abscissas and the midpoint distance (d) as the weighted value as the axis of ordinate. As for the axis of abscissas, normalization is performed by setting the range y=n1-n2 where the midpoint is present to -1 to +1 and as for the axis of ordinate, normalization is performed by setting the minimum value of the midpoint distance (d) to 0 and the maximum value to 1.  On the basis of a semicircular figure, the cumulative error difference between the figure of the normalized midpoint weighted graph and a reference graph is calculated and when this error is within a set error range, it is judged that the original figure is an ellipse.
