SAN FRANCISCO, March 7 (Xinhua) -- The world's leading hard rive producer Western Digital Corp. on Monday announced that it has agreed to buy Hitachi Ltd.'s hard disk drive unit for about 4. 3 billion U.S. dollars, a move that will create a dominant player in the industry.Western Digital said that it plans to acquire Hitachi Global Storage Technologies, a wholly-owned subsidiary of Hitachi Ltd., in cash and stock.The proposed combination will result in a customer-focused storage company with the industry's broadest product lineup backed by a rich technology portfolio, Western Digital said.According to their agreement, the resulting company will retain the Western Digital name and remain headquartered in Irvine in the U.S. state of California.The transaction has been approved by the board of directors of each company and is expected to close during the third quarter of 2011.With the purchase, Western Digital will claim 49.6 percent share of global hard disk drive unit shipments based on latest quarterly statistics, compared to 29.4 percent for Seagate Technology LLC, the industry's No. 2 supplier, research firm iSuppli pointed out.The deal will give Western Digital a lead of 20.2 percentage points over Seagate, up from a mere 2 points without the acquisition, iSuppli said in a research note released Monday.The acquisition will also allow Western Digital to enter the critical enterprise hard disk drive segment, where it currently is only a marginal player.Analysts believed that the purchase might be a consequence of declining hard disk drive shipments, which are being impacted by the rising sales of tablet computers, which don't use hard disk drives and are cutting into the sales of mobile PCs, a major market for hard drives."Amid weaker industry conditions, organic sales growth is more difficult to achieve, prompting hard disk drive suppliers to engage in acquisitions to gain market share," iSuppli noted.

WASHINGTON, May 20 (Xinhua) -- Two U.S. astronauts conducted the first of four spacewalks for space shuttle Endeavour's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) said.According to the U.S. space agency, Endeavour's mission specialists Andrew Feustel and Greg Chamitoff completed the six-hour, 19-minute spacewalk at 9:29 a.m. EDT (1329 GMT). They successfully installed antennas for the External Wireless Communication system, routing cables, setting up the antenna, installing handrails, and connecting power cables.Because of a carbon dioxide sensor failure in Chamitoff's spacesuit, flight controllers limited his spacewalk time to about six hours 20 minutes, 10 minutes less than the planned six hours and 30 minutes. There was no indication his suit's carbon dioxide levels would rise. However, they deferred tasks to remove a micrometeoroid debris shield to access and attach some of the connection points.This was the 245th spacewalk conducted by U.S. astronauts. It was Feustel's fourth spacewalk for a total time of 27 hours and 17 minutes, and Chamitoff's first.Endeavour lifted off on Monday morning from Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.

BEIJING, Jan. 28 (Xinhua) -- China will further its efforts to harness the Huaihe River over the next five to 10 years in a bid to support the economic development of the regions along the river.The decision was announced Friday in a statement released after an executive meeting of the State Council, China's Cabinet, which was presided over by Premier Wen Jiabao.The work will include upgrading dams and water gates in flood diversion programs and building more irrigation and water conservancy projects in low-lying lands along the Huaihe River, said the statement.Further, efforts will be made to guard against water pollution and help urban and rural residents in the Huaihe River regions have sufficient access to clean water, it said.Also, more flood control reservoirs will be constructed, while more residents will be relocated from flood diversion areas as well as flood land.The cabinet urged government departments to earmark more funds and enhance management and cooperation in implementing these measures.The 1,000-kilometer Huaihe River, the third longest water way in China, originates from Mount. Taibai, central Henan Province, and runs eastward between the Yangtze River and the Yellow River, the two largest rivers in the country. It cuts through Henan and east China's Anhui and Jiangsu provinces before entering the Yangtze River via the Hongze Lake.The flood-prone river has a drainage area of about 180,000 square kilometers.
