Title: Video signal sync. pulse detector
Inventor: FLING RUSSELL TOMAS
IPC: H04N5/10
Filed: 1990-04-17
Granted: 2000-01-15
Abstract: A detector (10) for vertical synchronizing pulses comprises a nonwrapping up/down counter (14) and a comparator (18). The counter (14) samples the level of a composite synchronizing signal at a sampling rate. The counter (14) has a numerical output which increases responsive to detection of said level during a sample interval and decreases responsive to nondetection of said level during a sample interval. The comparator (18) generates a vertical sync detection pulse when the numerical output of the counter (14) is greater than a reference value. In order to provide hysteresis, the numerical value is alternately one of first and second numerical reference counts, the first reference count being greater than the second reference count. The comparator (18) initiates the vertical sync detection pulse when the numerical output of the counter (14) rises above the first reference count and terminates the vertical sync detection pulse when the numerical output of the counter (14) falls below the second reference count. The numerical reference supplied to the comparator (18) is changed at times corresponding to initiation and termination of each vertical sync detection pulse. A pulse shaping circuit may comprise a latch (22) for sampling the output of the comparator (18) and generating a vertical synchronizing signal.

Granted: 1995-02-02
Abstract: A method for preparing a transparency involves application of hot melt ink to a transparent substrate to form a three-dimensional pattern with subsequent heating of the hot melt image above its melting point to change the configuration of the upper surface. In the embodiment described in the specification, a hot melt ink image on a substrate is treated in a continuous manner by moving it along a platen having a heating zone to melt drops of hot melt ink and cause them to spread on the substrate. The platen has a flat central portion and curved portions at each end with curvatures sufficient to prevent formation of cockle. At the output end of the heating zone, the substrate is moved continuously into a quenching zone where a cooling platen cools the substrate by thermal contact at a rapid rate to prevent crystallization or frosting of the hot melt ink image. After the quenching zone, the substrate is moved along a surface having a reverse curvature with respect to the curved portions of the heating platen to eliminate residual curvature of the substrate resulting from the curved portions of the heating platen.

Granted: 1997-06-28
Abstract: The invention concerns compounds of formula (1) wherein R stands for methyl or ethyl and  stands for prophylene, butylene or pentylene in the case of ring shape formed by bonding two R's; A and A' stand for ammonia, methylamine, isoprophylamine, cycloprophylamine, cyclobutylamine, cyclopentylamine and cyclohexylamine and trans-1,2-diaminocyclohexane, 2,2-dimethyl-1,3-prophanediamine,1,1-cyclobutanediamine, ethylenediamine,   1,1-cyclopentandimethaneamine, 1,1-cyclohexanediamine and stands for terahydro-4H-piran-4,4-dimethaneamine in the case of a chelate form. A platinum chelate compound is produced by reacting a alkali metal and a platinum nitrate derivative or a platinum nitrate derivative of which mole ratio is 1 : 1 by using water as a solvent , followed by condensing and precipitating.
