    摘要: 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. By the combinational use of the recognition result and the layout shape generating function prepared separately, the layout shape of the subsidiary structures are determined. Shapes of objects determined through the above process are laid out automatically, while avoiding obstacles, within a predetermined space. According to still another form, layout patterns of variable structure memorizing the object layout and wiring affair are prepared in advance, and a layout plan for a circuit having a hierarchical structure is created through the operation of embedding the circuit to be laid out into a pattern.

    摘要: There is provided a perpendicular magnetic recording head device which can increase magnetic field gradient to exhibit excellent recording performance while maintaining magnetic field intensity capable of performing information recording well. In a perpendicular magnetic recording head device composed of a main magnetic pole layer and a return path layer which are laminated with a nonmagnetic insulating layer therebetween, the return path layer has a two-layer structure composed of a low saturation magnetic flux density layer (low Bs layer), and a high saturation magnetic flux density layer (high Bs layer) formed an the low Bs layer and made of a material that has a relatively high saturation magnetic flux density. In a front end surface of the return path layer, the low Bs layer and the high Bs layer are exposed.

    摘要: An electric rotating machine has a rotor having N and S poles and includes a stator with an annular stator core and slots. Multiple-phase stator windings are embedded in the slots, and are formed by winding continuous wires such that straight parts of the stator windings pressed in a flat shape are wound in rings around a grooved cylindrical member. The cylindrical member is inserted into a bore defined by the annular stator core so that the grooves of the cylindrical member are arranged opposite to the slots. The sets of the windings are folded back alternately outside the slots of the stator core and are wound so the sets of the windings are embedded alternately in the direction of the depth of the slots. Leading and trailing ends of the continuous wires are superposed after being wound at least one turn around the circumferentially arranged slots of the stator.
