  • Patent number: 4735074
    Abstract: A multi-stage roll mill for producing a lengthy continuous rolled sheet material by a one-pass operation, comprises a driven central working roll, and a plurality of peripheral working rolls arranged spaced apart and on the periphery of the central working roll, the diameter of each of the peripheral working rolls being much smaller than that of the central working roll. Each peripheral working roll has a screw-down mechanism which is capable of freely adjusting the gap between the periphery of the peripheral working roll and the periphery of the central working roll. The peripheral working rolls are arranged in such a manner that the work being held in the gap between the peripheries thereof and the periphery of the central working roll is subjected to continuous multi-stage rolling.

  • Patent number: 4700317
    Abstract: Automatic layout planning without previously specifying place of each parts is made possible by utilizing groups of rules each comprising a condition section and a procedure section. An appropriate group of rules can be called from a knowledge base according to an intermediate layout plan generated in a data structure by a rule interpreter.

  • Patent number: 4651284
    Abstract: The structure of a circuit which is given basic net data is stored as a pattern, the compliance of the basic net data with the pattern is checked by the separately prepared search function, and upon fulfillment of compliance the pattern is determined to exist within the circuit. The subcircuit to be recognized by elements is not directly defined, but is defined using an intermediate expression defined recursively so as to implement a search through pattern matching. In another form, one input terminal is specified, which is followed by a search for blocks having the terminal as an input node and the search for blocks having one of the output node strings as an input node recursively and cyclically until the output terminal is reached, so as to extract a string of nodes on which the signal is propagated. The system is provided with functions for recognizing and comprehending subsidiary structures of the circuit which are not defined by the entered net data.

  • Patent number: 4646185
    Abstract: A magnetic head having a central read/write core and a pair of erase cores is assembled with a leaf spring having corresponding slots for the cores. The leaf spring has a pair of clip arms at each end. The leaf spring with the assembled magnetic cores is fitted on an insulating holder case which has grooves for receiving the clip arms. The cores can be assembled more readily on the leaf spring than on the holder case, thus facilitating the assembly process and miniaturization of the magnetic head.
