Abstract: After an event processing that an application program corresponding to a first event request information should execute is executed with respect to at least one of window objects and variables which should be contained in the application program applicable to a first event request from a client PC, a Web server maintains the window object and variable, which are after the event processing, into a Web session and, at the same time, transmits the window object after the event processing to the client PC. Further, when the Web server further receives a second event request applicable to the same application program, the Web server executes an event processing corresponding to the second event request using the window object and variable stored in the Web session.

Abstract: A thermoplastic resin composition comprising (A) 45 to 99% by weight of a graft copolymer obtained by special graft polymerization of a monomer (b) such as an aromatic vinyl compound, a methacrylic ester, etc. in the presence of grafted polymer rubber (a), and (B) 55 to 1% by weight of a thermoplastic aromatic polyester resin can yield shaped articles excellent in impact resistance, chemical resistance, etc. with excellent processability.

Abstract: A grafted copolymer containing low cis-polybutadiene having a Mooney viscosity of 30 to 40 as a rubber component, and 30% by volume or more of particles of said rubber component becoming non-spherical rubber particles when molded into a molded article, is suitable for use as a low gloss agent which is usable in the fields of internal and external automotive trims, exterior parts of household electric appliances, etc.
