TOSHIBA, SHARP RESTRAIN LAP-TOP PC EXPORTS TO EC Toshiba Corp <TSBA.T> and Sharp Corp <SHRP.T> decided to maintain exports of lap-top personal computers to the European Community (EC) at last year's levels, despite the halt of shipments to the U.S., Company spokesmen told Reuters. They said the voluntary restraints were aimed at averting EC sanctions urged by European computer makers. The Europeans feared Japanese personal computers would flood EC markets after Washington imposed 100 pct tariffs last April. Toshiba and Sharp together control about 40 pct of the personal computer market in the EC, the Sharp spokesman said. Toshiba said exports of T1100 and T3100 lap-top computers would continue at 5,000 units a month for the time being. Sharp said exports to the EC of PC 7000 series lap-top personal computers would continue at last year's level of 12,000 to 16,000 units a year. Washington imposed the tariffs because of Japan's alleged failure to uphold a 1986 agreement on semiconductor trade.
