Title: Nonaqueous electrolyte secondary battery
Inventor: FUKUHARA TOMOHITO
IPC: H01M10/05
Filed: 2001-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery in which life elongation by suppressing precipitation of dendrite can be aimed at. SOLUTION: A plural number of exposed parts 14 are installed at a positive electrode active substance layer 13, and these exposed parts 14 are arranged in a radial form with the center of a corner part 13A positioned on the diagonal line of a protruding position 11A of a positive electrode reed 11. Accordingly, as it goes farther from the positive electrode reed 11, the exposed area per unit area becomes larger and the existing amount of the positive electrode active substance decreases. Here, the utilization rate of the positive electrode active substance 13 becomes lower as it goes farther from the positive electrode lead 11.  Therefore, by reducing the amount of the positive electrode active substance as it goes farther from the positive electrode lead 11, the utilization rate of the positive electrode active substance can be made equal in the whole positive electrode active substance layer 13 and deviation of current distribution can be prevented from occurring. By this, the dendrite can be prevented from precipitating.

IPC: H04W4/00
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a mobile telephone system that can use a magnetic disk of a large capacity for storing data of the mobile telephone without causing an access delay even with low power consumption. SOLUTION: A display section 104 displays an operation menu. Mobile keys of a key operation section 105 moves a cursor and a selection key selects any of choices of the operation menu. The operating state of the magnetic disk is shifted according to the choice at the cursor position. Further, selecting the choice shifts the operating state of the magnetic disk. The power of the magnetic disk is controlled according to the shifted operating state. The operating state of the magnetic disk may be shifted according to the information of the free capacity of a semiconductor memory and a disk control key. Since the operating state of the magnetic disk is shifted in advance to an optimum state by the motion of the cursor, a delay in data access can be reduced while reducing the power consumption.
