20150113473 | ELECTRONIC DEVICE - An electronic device that increases both visibility and selectability of executable programs. The electronic device includes a touch panel display having an elongated shape, a memory storing programs, and a processor controlling program execution and the display. The touch panel includes a first display region and a second display region contiguous with and narrower than the first display region. The display displays an execution image of a first program in the first display region and an icon image of a second program in the second display region in a smaller display area than the execution image. When the processor detects contact at the icon image and detects that the contact moves towards the first display region, the processor causes the display to display an execution image of the second program in the first display region. | 04-23-2015 |

20150185766 | WEARABLE ELECTRONIC DEVICE - A wearable electronic device according to the present disclosure includes a first belt, front surface of the first belt being provided with a displaying unit having a curved display face; a second belt; a hinge that connects a first end of the first belt to a first end of the second belt. A shape of a space formed by the first and second belts is an elliptical shape when the device worn around a subject is viewed from a side. The hinge has higher flexibility than the first and second belts. The device has a first engagement unit provided at a second end and a rear surface of the first belt, and in a region where the elliptical shape has smaller curvature than other regions. The device has a second engagement unit provided at an outer side of the second belt and engaging with the first engagement unit. | 07-02-2015 |
20150244020 | METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE BATTERY, AND NONAQUEOUS ELECTROLYTE BATTERY - A negative electrode active material layer containing at least one selected from silicon and a silicon compound as a negative electrode active material is formed, and an amount of lithium exceeding an amount corresponding to a theoretical capacity of the negative electrode active material layer is brought into contact with the negative electrode active material layer so as to prepare a negative electrode. A positive electrode containing a lithium-absorption material capable of irreversibly absorbing lithium is prepared. The positive electrode, the negative electrode, a separator, and a nonaqueous electrolyte are enclosed inside an outer enclosure. A chemical conversion treatment of the negative electrode active material is performed with the lithium brought into contact with the negative electrode active material layer. | 08-27-2015 |
