  • Patent number: 9255972
    Abstract: A method of testing a secondary battery includes first to fourth steps. At the first step, the secondary battery after manufacture is charged to a first voltage. At the second step, a second voltage lower than the first voltage is set as a target voltage and discharge or charge is performed in a constant-current constant-voltage mode before the secondary battery is left standing. At the third step, the open circuit voltage of the secondary battery is measured before and after the secondary battery is left standing. At the fourth step, it is determined whether the secondary battery is a conforming item or not based on the difference in the open circuit voltage before and after the secondary battery is left standing.

  • Patent number: 9141893
    Abstract: In the invention, an inclination amount of sensors is reflected in positional deviation correction patterns, and for correcting formation positions of images of various colors, the positional deviation correction patterns are formed on a conveying belt. The positional deviation correction patterns are detected by the sensors. A control unit calculates positional deviation correction amounts based on detection results of the positional deviation correction patterns. Based on the calculated positional deviation correction amounts, the control unit performs calculation for correcting the positional deviation correction patterns, and cancels the inclination amount reflected in the calculation results to obtain final positional deviation correction amounts. Skew correction is performed based on the final positional deviation correction amounts, and thus, the positional deviations are corrected.

  • Patent number: RE45928
    Abstract: In a memory module including a plurality of DRAM chips which transmit/receive a system data signal with a predetermined data width and at a transfer rate and which transmit/receive an internal data signal having a larger data width and a lower transfer rate as compared with the system data signal, the transfer rate of the system data signal is restricted. Current consumption in DRAMs constituting the memory module is large, hindering speed increases. For this memory module, a plurality of DRAM chips are stacked on an IO chip. Each DRAM chip is connected to the IO chip by a through electrode, and includes a constitution for mutually converting the system data signal and the internal data signal in each DRAM chip by the IO chip. Therefore, wiring between the DRAM chips can be shortened, and DLL having a large current consumption may be disposed only on the IO chip.
