First held last year in Hanno, about 50 kilometers northwest of Tokyo, the Hadashi (barefoot) Marathon is the brainchild of lead organizer Tsuyoshi Yoshino, who said that the real technology are the athletes themselves, not fancy running shoes.
Panasonic Corporation today announced that it has developed a solar lantern that doubles as a charger for people living without electricity. With a built-in rechargeable battery to store solar energy during the day, the lantern provides light at night and can also be used as a power source to charge small mobile devices like mobile phones.
With the new technology, it becomes possible to eliminate the need for a position sensor used for a permanent-magnet motor, enabling to reduce motor size and simplify installation and maintenance. Also, because the technology enables to quickly generate a high torque, it can be applied to conveyor belts, elevating machines, etc.
Nagatomo is recovering from a knee injury. CSKA Moscow said Honda is unfit, but has not elaborated on the specifics of his condition.

Fuji Xerox showed an electrophoretic type electronic paper (e-paper) that realizes color display without using a color filter on the opening day of SID 2012, which runs from June 3 to 8, 2012, in Boston, the US.
Because the e-paper does not use a color filter, it can realize a brighter and more vivid display, the company said (thesis number 8.4).
Hitachi and Hitachi Industrial Equipment Systems co-developed a permanent magnet synchronous motor with an efficiency of 93% without using a neodymium (Nd-Fe-B) magnet, which contains a rare-earth material.
The efficiency of the motor is equivalent to "IE4," which is the highest rank in the motor energy efficiency guidelines of the "IEC60034-31" international standard. The motor has an output power of 11kW and is targeted at industrial motors such as of large fans for sending air and fluid pumps.
