Japan on Tuesday warned users of Apple iPod nanos of a potential fire risk, after two new instances in which the popular portable music players overheated.
The economy, trade and industry ministry has received two new reports of minor fires in August in Tokyo caused by overheating iPod nanos, said ministry official Hiroyuki Yoshitsune. There were no injuries and the cause is still unclear, he said.
Japan had already launched an investigation in March after another Apple iPod nano sent out sparks. According to the ministry, Apple Computer has been notified of a total of 14 similar cases in Japan. Out of those, two users suffered minor burning.
The ministry said the incidents were caused by four models - MA004J/A, MA005J/A, MA099J/A and MA107J/A - of which 1.81 million units were sold between September 2005 and September 2006 in Japan.
"Users need to be careful about overheating of the machines," the ministry said in a statement, warning that particular care is needed when recharging the iPods.
"Our ministry told Apple to improve its technological development and probe the cause of the incidents so that similar incidents do not happen again," the official said.
There was no immediate comment from Apple. Public broadcaster NHK said the company has no plan to recall any iPods but is ready to exchange defective parts.
The US computer giant has already warned that iPod, iPod nano or iPod shuffle may generate excess heat while being charged in certain carry cases.
Lithium ion batteries, which Apple uses for iPods, are common in consumer electronics, such as mobile telephones and personal computers.
However, major battery makers, including electronics giant Sony Corp., have occasionally been forced to recall their lithium ion battery packs after reports of overheating and fire.
At precisely 9:23 am, the Polar Satellite Launch Vehicle (PSLV)-C9 rose into the sky, emitting thick orange flame, and placed in orbit an Indian cartography and a mini satellite to maintain leadership in the remote sensing domain. It also slung eight nano satellites into outer space - marking the world's second largest such mission.
The record is with Russia that launched 16 satellites at one go in 2007.
But there was uncertainty at the Satish Dhawan Space Centre in Sriharikota , about 80 km from the Tamil Nadu capital of Chennai, soon after the rocket blasted off. While the signal that three of the satellites had been separated successfully came in, there was no immediate news about the other seven.
Scientists of the Indian Space Research Organisation (ISRO) heaved a sigh of relief when the news that all satellites had separated came in, signalling that the mission was a success.
Fourteen minutes into the flight, the 44 metre tall rocket first slung the 690 kg Cartosat-2A and followed it by slipping the 83 kg mini satellite and the cluster of eight nano satellites into a high polar sun synchronous orbit (SSO).
"It is a memorable moment for Team ISRO. The rocket stuck to its path without any deviation and delivered all the 10 satellites in their intended orbit," said G Madhavan Nair, Head of ISRO, immediately after the launch.
Mission Director George Koshy said, "The success of this launch has added more responsibility on us for the prestigious Chandrayaan (moon mission)."
Immediately after the payloads were ejected into orbit, the Spacecraft Control Centre at Bangalore with the help of ISTRAC (ISRO telemetry, tracking and command network) network of stations at Bangalore, Lucknow, Mauritius, Bearslake in Russia, Biak in Indonesia and Svalbard in Sweden monitored the satellites' health.
Several firsts for ISRO
This is ISRO's second successful launch this year after January when it launched an Israeli satellite.
Monday's launch marked several firsts for ISRO - the first time an ISRO rocket carried 10 satellites at a time, the first time a mini satellite was designed and sent up and the first time the Indian space agency utilised the optimum capacity of the PSLV's core alone configuration.
The two earlier core alone PSLVs carried a payload of 352 kg and 535 kg.
The Rs 2 billion Cartosat-2A is the thirteenth Indian Remote Sensing satellite. The data from the satellite will find applications in urban and rural infrastructure development and management as well as land and geographical information systems.
The satellite carries an advanced panchromatic camera that can take pictures with a spatial resolution of about one metre and can cover a land strip of 9.6 km.
The mini satellite incorporates many new technologies and has miniaturised subsystems apart from multi and high spectral cameras.
India, a world leader in the remote sensing data market, earns around Rs 520 million from this.
After the latest launch, India has a total of eight remote sensing satellites orbiting the earth -- IRS-1C, IRS-1D, Oceansat 1, TES, Resourcesat 1, Cartosat 1 and Cartosat 2 and Cartosat 2A.
