Tokyo's Nikkei stock average closed lower on Wednesday, dragged down by steep losses in certain technology shares such as Toshiba Corp <6502.T> after their business outlooks failed to satisfy investors. The benchmark Nikkei lost 0.34 percent to close at 12,004.29. But the broader TOPIX index added 0.16 percent to reach 1,206.92, thanks to gains in banks.|||www..com
