A group company of the Yomiuri Shimbun, one of the world's largest newspapers by circulation, and five others will pay a total of 2.2 billion yen ($19 million) to buy 32% of Tokyo Kikai from top shareholder Asia Development Capital (ADC).

The 106-year-old maker has been engaged in a closely watched battle with ADC, which owns about 40% of the company. It won supreme court approval last year for a "poison pill" takeover defence against the investment firm.
