Title: Image pickup system comprising a memory of a small capacity
Inventor: NAGURA RIICHI
IPC: H04N13/161
Filed: 1991-04-10
Granted: 1996-07-16
Abstract: In an image pickup system which is used on a craft flying over an object zone and comprises a first (photoelectric) transducer (21) for producing a first partial (electric) signal representative of a partial image of a partial zone lying forwardly of the craft flying at a first position and a second transducer (22) for producing a second partial signal representative of another partial image of the partial zone lying directly under the craft flying, an interval of time later, at a second position spaced from the first position by a distance between two partial zones picked up by the first and the second transducers when the craft is at the first position, a compression unit (90 ) compresses the first and the second partial signals into first and second compressed signals.  A delay circuit ( 54-1) gives the first compressed signal a delay equal to the interval of time and produces a delayed signal.  A subtracter  (55-1) calculates a difference between the delayed signal and the second compressed signal and produces a difference signal.   The first compressed signal and the difference signal are transmitted by a transmitter to a ground station to obtain  a stereo image of the object zone.   Preferably, the image pickup system should comprise a third transducer (23), another delay circuit (54-2), and another subtracter (55-2).  The delay circuit is implemented by a memory.

Abstract: An aramid yarn, preferably poly(p-phenylene terephthalamide), is coated with a water swellable superabsorbent material. The swelling value of the yarn is at least 60. The superabsorbent provides water blocking capability to the yarn, so that it is suitable for use as a strength member, for example, in water tight optical communication cables. The yarn is made by successively treating an aramid yarn with a water-in-oil emulsion, a superabsorbent material being present in the water phase of the emulsion, and removing the liquid components from the treated yarn by evaporation.
