摘要:
A computer system replaces an input device, such as a mouse, with a video camera having an image recognizing function and an image extracting function to detect motions of the operator's body directly, and controls a computer apparatus to move a cursor and check on an icon on the basis of the output signals of the video camera. The computer system controls the computer apparatus also on the basis of a signal provided by the video camera upon the detection of light emitted by a particular object. The computer system is capable of making the computer apparatus understand an operator's intention without using any conventional input device, such as a mouse, and of facilitating an operator's input operation.

A polyarylene sulfide resin composition obtained by melt-mixing a mixture comprising resin components comprising as main resins(A) a polyarylene sulfide resin and(B) a polyorganopsiloxane graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer containing at least an epoxy group-containing vinyl monomer onto a compound rubber in which a polyorganosiloxane rubber and a polyalkyl (meth)acrylate rubber have been inseparably united with each other. The composition of the present invention, whether it contains a filler or not, is excellent in compatibility between the polyarylene sulfide resin and polyorganosiloxane graft copolymer. If this composition is extrusion-molded or injection-molded under the common molding conditions, it keeps its original dispersed and mixed condition without showing a phase separation. Consequently, this composition has an excellent performance that impact resistance also has been given to the polyarylene sulfide resin without largely injuring excellent properties inherent to the resin. Particularly, this composition is very little deteriorated in impact strength when it is put in wet heat conditions under pressure, and therefore it is usable in such conditions.

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.

摘要:
A polyarylene sulfide resin composition comprising a resin composition obtainable by polymerizing 40 to 0.1 part by weight of an unsaturated polyester and 0.01 to 30 parts by weight of a monomer having one or more ethylenic unsaturated bonds in the presence of 100 parts by weight of a composition comprising 1 to 99 wt. % of a polyarylene sulfide resin and 99 to 1 wt. % of a thermoplastic polyester. Since the polyarylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Consequently, the composition of the present invention is very superior in that the adhesive property of paint film (paintability), which the conventional polyarylene sulfide resins do not have well, has been improved without a large reduction in the excellent properties of the polyarylene sulfide resin.
