Granted: 1992-03-24
Abstract: Abstract of the Disclosure:     A pattern recognition system comprises a preprocessing unit receiving a give pattern for converting the given pattern into a two-dimensional bit pattern. There is provided a first cell block having a plurality of layers each of which is composed of a plurality of nonlinear oscillators arranged in a two-dimensional matrix. The nonlinear oscillators in each of the layers are coupled so as to be excited by a corresponding bit of the bit pattern, and are coupled to adjacent nonlinear oscillators in the same layer so as to mutually emphasize the oscillation in a predetermined direction different from those predetermined for the other layers, so that in each of the layers, there are selectively excited the nonlinear oscillators corresponding to a continuous line segment contained in the bit pattern and aligned in the excitation emphasizing direction of that layer. There is also provided a second cell block having a plurality of layers each of which is composed of a plurality of nonlinear oscillators arranged and coupled in manner similar to the first cell block but is such that in each of the layers, there are selectively excited the nonlinear oscillators corresponding to an end of a continuous line segment formed in the two-dimensional bit pattern and aligned in a direction coincident with the direction of that layer. A memory composed of a plurality of nonlinear oscillators is selectively excited by the exciting nonlinear oscillators of the first and second cell blocks, whereby the nonlinear oscillators of the memory corresponding to an exciting pattern of the exciting nonlinear oscillators of the first and second cell blocks oscillate at a frequency inherent to the given pattern.

Abstract: The microstructure of a metallic material is controlled to modify the final ultimate tensile strength of the material.          The method involves the steps of continuously moving the material along a path past a heating means and a cooling means.  The material is heated by the heating means to an initial temperature to change the material to a first microstructure.  As material continues in motion this temperature is reduced by the cooling means according to a selected cooling pattern such that the material changes to a second microstructure that depends on the selected cooling pattern.  The material is elongated as it is in motion during both the heating step and the cooling step.

Abstract: ABSTRACT            The web-fed printing machine preferably intended for the printing of banknotes has two closely adjacent impression cylinders       , each of which interacts with several blanket cylinders       .  Each blanket cylinder is inked by a plate cylinder        which receives its ink from its own inking unit                .  The paper web     runs between the respective impression cylinder and blanket cylinders       , partially looping first round one impression cylinder     and then in the opposite direction round the other impression cylinder , so that the two sides of the paper are successively printed directly with the individual colors.  All the blanket  and  plate  cylinders  interacting  with  an impression cylinder        are arranged on a respective common   exchangeable   machine   stand Consequently, in order to exchange the blanket and plate cylinders for cylinders of a different diameter for the purpose of changing the printing format,  the machine stands         equipped with corresponding cylinders are exchanged as a whole.
