Title: Y/c separator
Inventor: ASADA SEIGO
IPC: H04N9/78
Filed: 1988-05-10
Abstract: PURPOSE:To prevent malfunction of a correlation detection circuit and to reduce color blur by providing an edge detection circuit detecting an edge of a low frequency component and using a detection output from the edge detection circuit so as to control the correlation detection circuit. CONSTITUTION:The edge detection circuit 37 detects an edge of a luminance signal whose band is limited by a low pass filter 36. When the edge detection circuit 37 detects the edge of the luminance signal, the edge detection signal 38 controls the correlation detection circuit 39. Then a comb-line filter output selected before the detection of the edge is outputted from a color signal output terminal 46. In case of detecting the edge, a low pass filter 36 eliminates a high frequency component of the composite video signal 35 outputted from a delay line 34 so as to avoid malfunction of the edge detection circuit 37 and then detects the edge. Thus, even if a composite video signal with a large change in the luminance signal is inputted, malfunction of the correlation detection circuit is prevented by the edge detection circuit to reduce color blur.

Filed: 1978-09-14
Abstract: PURPOSE:To obtain the optical fiber connector which does not cause degradation in characteristics owing to tmeperature and humidity by burying the glass and ceramics of the coefficient of expansion lower than the fixing member which buries and bonds optical fibers in said member. CONSTITUTION:A glass plate 12 is placed under a splicing groove and is buried by epoxy resins, whrerby a groove substrate 11 as a fixing member is formed. Glass fibers 9, 10 are buried in this base 11 and are bonded and fixed from above by the glass plate 13. According to this bonding method, the increase in loss is hardly observed in contrast with the case of only the epoxy where the loss reached several times the initial one in one month after giving temperature changes of 60 deg.C-20 deg.C and 4 cycles/day as compared to the case when the optical fibers are buried and connected by the epoxy resins alone. Stability may be increased as against the change in heat cycle and temperature by the auxiliary member buried  near the optical fibers.

Title: Partial recording device
Inventor: SATOU YOUJIROU
IPC: G03G15/04
Filed: 1979-09-05
Abstract: PURPOSE:To avoid producing the useless blank part between the picture information to be recorded partially, by transporting the recording paper in correspondence to the actual reading width of the original reading device. CONSTITUTION:The optical shutter provided to the optical monitor window is connected to the variable resistor VR and receives the DC voltage corresponding to the shutter. This voltage is then converted via the A/D converter into the digital  signal having the numerical value corresponding to the reading width to be applied  to the pulse counter PCT. The PCT counts the pulses sent from the pulse source PS by the number corresponding to the reading width. Based on the count value of the  PCT, the output image given from the solid state image sensor SIS is made visually  to correspond to the set reading width. At the same time, the count value of the  PCT is given to the motor driving circuit MD to drive the recording paper feeding  motor M. Thus the recording paper is shifted in accordance with the reading width.  As a result, the useless blank part can be eliminated even in the reading of the  original.
