A method for producing a non-aqueous electrolyte secondary battery includes: subjecting a mixture of a negative-electrode active material on which oil has been adsorbed, CMC and water to hard kneading to prepare a primary kneaded mixture; diluting the primary kneaded mixture with water to prepare a slurry; and adding a binder to the slurry. The method further includes defining an amount of the oil to a value equal to or more than 50 ml/100 g and equal to or less than 62 ml/100 g, wherein the amount of the oil is an amount at the time when the viscosity characteristics of the negative-electrode active material exhibits 70% of the maximum torque that is generated when the oil is titrated onto the negative-electrode active material. The 1% aqueous solution viscosity of the CMC is defined to a value equal to or more than 6000 mPa·s and equal to or less than 8000 mPa·s.

An image processing apparatus includes an approximate-surface calculator that calculates multiple approximate surfaces that each approximate the pixel value of a pixel included in an examination-target region of an image; an approximate-surface selector that selects at least one approximate surface from the approximate surfaces on the basis of the relation between the pixel value of the pixel in the examination-target region and the approximate surfaces; an approximate-region setting unit that sets an approximate region that is approximated by at least the selected one approximate surface; and an abnormal-region detector that detects an abnormal region on the basis of the pixel value of a pixel in the approximate region and the value corresponding to the coordinates of that pixel on at least one approximate surface.

In a flash memory, after an initial write operation ends, each bit line associated with a memory cell subjected to a write is precharged and each bit line associated with a memory cell that is not subjected to the write is discharged and verified to detect a memory cell low in threshold voltage and a memory cell thus detected is subjected to an additional write. The verification can be verified without being affected by a current flowing through the memory cell that is not subjected to the write. All memory cells can have their respective threshold voltages set accurately.

In a chip type solid electrolytic capacitor including a capacitor element and a packaging resin covering the capacitor element, the packaging resin has a mount surface and a side surface adjacent to the mount surface. A terminal is electrically connected to the capacitor element and coupled to the packaging resin. The terminal extends along the mount surface and the side surface to have an outer surface exposed from the packaging resin and to have an inner surface opposite to the outer terminal surface. The inner surface has a stepwise shape formed by forging.

A monitor circuit for monitoring external potential EXTVDD and variable delay circuit determine the time interval in which signal ZODACT is being at the L level according to the potential level of external potential EXTVDD, and thus the supplying time of external potential EXTVDD can be dynamically changed. When external potential EXTVDD is at the upper limit of specification of product, the supplying time is short, thereby preventing overcharge of memory cells or bit lines. When external potential EXTVDD is at the lower limit of specification of product, the supplying time becomes longer, thereby ensuring a sufficient over-driving time interval. It is possible to ensure the reliability of the memory cells and perform the reading operation throughout the entire range of the specification of product of external potential EXTVDD. Therefore, it is possible to provide a semiconductor memory device capable of performing a reading operation at high speeds while ensuring the reliability.

A sense amplifier driving line is connected to the source of an N-channel MOS transistor. Accordingly, even if a control signal attains H level, a sub-amplifier will not operate. This is because the sense amplifier driving line and an LIO line pair both attain a precharge potential, and a gate-source voltage of an N-channel MOS transistor attains 0V. Thus, it is not necessary to add a circuit configuration for supplying a signal notifying of activation of a row block, and a semiconductor memory device with a smaller area is obtained.

Data of 2-bits prefetched from a memory array and transmitted to an amplifying circuit via a data bus is ordered in accordance with the least significant bit of a column address which is a start address supplied from the outside. The first data is output to read data buses and is directly transmitted to an output data latch. The second data is held once by a second data latch and, after that, transmitted to the output data latch. Since the first data is transmitted from the amplifying circuit directly to the output data latch, the time from a read command is received until data is started to be output can be shortened.
