In a method of designing cells applicable to different first and second design automation systems, first and second cells circuit-designed by the first and second design automation systems, respectively, are demarcated into a logic function portion and an input/output portion. A plurality of sets of common lithography patterns for the logic function portions of the first and second cells are determined such that each common lithography pattern set is shared by those of the first and second cells which have same logic function in the first and second design automation systems. A first set of lithography patterns for the input/output portions of the first cells in the first design automation system and a second set of lithography patterns for the input/output portions of the second cells in the second design automation system are determined, respectively. The first and second sets of lithography patterns are, at their external ends, in an arrangement satisfying requirements of the first and second design automation systems, respectively. The logic function portion of one or more of the first cells in the first design automation system having the determined set of common lithography pattern is combined with the input/output portion of the second cells having the second set of lithography pattern in the second design automation system.

In a database system for map information, matching and retrieving operations are carried out between an attribute database associated with a business and a map database. A matching key word is separated into a common noun part and a proper noun part, a synonym and an abbreviated word are inferred by employing rules respectively. Furthermore, a candidate key word is inferred by employment of a rule for combining these results at an optimum state, whereby a matching process is performed. Another address database is employed so as to realize a mutual retrieving operation even when the attribute database is not matched with the map database.

A magnetic recording medium, produced by preparing a resin solution for magnetic paint having as a main component thereof a copolymer of (A) vinyl chloride, (B) a vinyl carboxylate, (C) an unsaturated carboxylic acid, (D) an unsaturated carboxylic anhydride and (E) vinyl alcohol, containing 50 to 90% by weight of (A) based on the total of the amounts of (A), (B) and (E), 1 to 15% by weight of (E) based on the total of the amounts of (A), (B) and (E), 0 to 30% by weight of (D) based on the total of amounts of (C) and (D), and 1 to 5 parts by weight of the total of (C) and (D) based on 100 parts by weight of the total of (A), (B) and (E) and having an average polymerization degree of 100 to 400, mixing 10 to 80% by weight of said resin solution with 90 to 20% by weight of a radiation curable resin, blending the resultant mixture as a main component with a magnetic powder, applying the resultant magnetic paint to a non-magnetic substrate, and curing the applied layer of paint with radiation.
