IPC: B23K13/01
Filed: 1992-08-14
Abstract: A method of continuously hot-rolling sheet bars in which a roughly rolled leading sheet bar and a trailing sheet bar are abutted prior to a hot finish rolling step.          Plastic deformation of either or both of the cut rear and front end portions of the leading and trailing sheet bars is applied.   End portions are brought into contact with each other due to metal flow, forming a gap portion between the sheet bars.    The thickness of the sheet bar around the gap portion is enlarged in comparison to the thickness of the contact portions, and hot finish rolling fills the gap so that the bars are strongly joined over their width.

Abstract: First, second, third and fourth MOS transistors each have a gate terminal, a first current flowing terminal, and a second current flowing terminal.  The first current flowing terminal of the first MOS transistor is coupled to the first current flowing terminal of the second MOS transistor at a first voltage node; the first current flowing terminal of the third MOS transistor is coupled to the second current flowing terminal of the first MOS transistor at a first output node; the first current flowing terminal of the fourth MOS transistor is coupled to the second current flowing terminal of the second MOS transistor at a second output node; and the second current flowing terminal of the fourth MOS transistor is coupled to the second current flowing terminal of the third MOS transistor at a second voltage node.  A transistor control unit is coupled to the gate terminals of the first, second, third and fourth MOS transistors for biasing the transistors for alternately flowing current through the first and fourth MOS transistors or through the second and third MOS transistors   A first transmission line is coupled to the first output node, and a second transmission line is coupled to the second output node.  A terminating resistance is coupled to the first transmission line and to the second transmission line for preventing signal reflections on the first transmission line and the second transmission line.  The first transmission line is coupled to a first input terminal of an ECL circuit element, and the second transmission line is coupled to a second input terminal of the ECL circuit element.  The signals on the first and second transmission lines are used for driving the gates in the ECL circuit element.  A source resistance is coupled between the first voltage node and a voltage source.  The source resistance ensures that the voltage at the first and second output nodes do not exceed the saturation values of the driven ECL gates while simultaneously maintaining a strong differential signal across the first and second output nodes.

Abstract: COMMAND AUTHENTICATION PROCESS            Abstract of the Disclosure A slave station, such as an orbiting satellite, and a master station, such as a ground control station, have their own lists of random pads.  The master and slave station lists are identical.  When the master station sends a critical command to the slave station, a selected one of the pads is combined with the command and transmitted to the slave station as a data communication message.  Each pad is used only once.  The slave station evaluates the received pad value using its version of the same selected pad. If the evaluation detects correspondence, then the command is authenticated and the slave station acts upon the command.  The random pads are generated by the slave station.  They are encrypted  using an asymmetric encryption process and transmitted to the master station so that the master and slave stations will operate on common sets of pads.

Abstract: A data processing system has a store, logically partitioned into different partial spaces, for storing vector data consisting of different elements.  The system also has address translation buffers, logically partitioned into pages of sizes prescribed for respective partial spaces, for translating the logical page number for each partial space to a physical page address.  An address translation controller is provided for, when any of the vector data stored in the store is to be accessed and if the elements are within the range of a prescribed number of pages, searching different entries in the address translation buffers, performing simultaneous address translation of the pages, and thereby accessing the vector data.  The number of simultaneously accessible elements is determined on the basis of the between-elements distance of the vector data and the size of the page of the partial space to which the desired vector data belong.  The invention improves the efficiency of the store and increases the throughput of vector data processing.
