Patent EP-0280217-A3 (EP)
IPC: G11B27/17
Filed: 1988-02-19
Abstract: A tape position detection apparatus is disclosed 
wherein a tape is first fed in a forward direction from 
one reel to another for a predetermined period of time, 
under the control of a tape transit control circuit 
(88). When the reels rotate, respective pulse genera­
tors (38, 40) generate pulses, which are counted by 
corresponding reel counters (42, 44). The counting 
period are set by control circuits (46, 48), and upon 
completion of a counting period, the count obtained is 
stored as first count data in a memory circuit. Also, 
as a capstan for feeding the tape rotates, a corre­
sponding pulse generator (64) generates pulses which 
are counted by capstan counters (60, 62). In accordance 
with the count, an operational circuit (68) calculates 
the residual amount of tape for presentation on a 
display (78). In the meantime, upon completion of the 
first counting period described above, the tape is fed 
in the reverse direction by a logic control circuit 
(50), during which time the count obtained when the 
tape was fed in the forward direction is compared, in a 
comparison circuit (52), with the count obtained when 
the tape is fed in the reverse direction. When the 
count data being compared become substantially equal, 
the tape is stopped.

the later is used, and a ZnSe 0.94  S 0.06  alloy semi­
conductor as an active layer (34, 44) is located between 
the cladding layers. The double-hetero structure semi­
conductor laser thus provided can perform the lasing at 
470 nm at room temperature.

Patent EP-0323558-A3 (EP)
Title: Polygon filling method
IPC: G06T11/40
Filed: 1988-11-21
Abstract: Two faster polygon fill routines are presented for filling polygons on 
a graphics display in addition to a conventional fill routine. The 
first fast fill routine fills polygons that are strictly convex. The 
second fast fill routine fills a larger class of polygons than the 
first fast fill routine which includes polygons being concave in the x 
direction, and polygons having crossing lines.  
     The first fast fill routine tests the polygon for strict convexity by 
testing for a consistent turning direction, and by testing for once 
around in the y direction. The first polygon fill routine then stores 
the maximum and minimum value of the pel selected by the Bresenham 
routine for each scan line of the polygon. The fill line is drawn from 
the pel having the minimum value to the pel having the maximum value 
for each scan line of the polygon.  
     The second fast fill routine tests the polygon to ensure that it can be 
filled with one unique fill line for each scan line of the polygon. 
The second fast fill routine stores both a minimum value and maximum 
value for each scan line line of the polygon for each line of the 
polygon. A fill line is then drawn from the least minimum value to the 
greatest maximum value for each scan line of the polygon.
