A rectangular battery having an electrode group which is inserted in a battery case having an airtight structure. The electrode group is formed by alternately stacking positive electrodes and negative electrodes via separators. The battery case is rectangular had has a closed bottom and an open part that is airtightly sealed by a cover. The outermost electrodes, which are located on both faces of the electrode group, are coated with an active material on a surface of a core. Furthermore, the outermost electrodes have the same polarity and the cores thereof directly contact an inside surface of the outer battery case. In one embodiment, the capacity of the outermost electrodes is smaller than the capacity of the inwardly disposed electrodes of the same polarity.

A container for containing printing liquid for supplying to an ink jet head for an ink jet recording apparatus. The container includes a first chamber containing negative pressure producing material and having an air vent communicating with ambient air and a supply port for supplying printing liquid to the ink jet head. The container also includes a second chamber communicating with the first chamber via a communication port and providing a printing liquid reservoir for the first chamber. The capillary force provided by the negative pressure producing material adjacent a wall extending from the communication port and decreasing in a direction perpendicular to and towards the wall at least adjacent a part of the communication port which is uppermost in use of the container.

A self-checking circuit, which is useful for a highly reliable system configuration, includes a logic circuit having an error detection function. For function blocks for feeding out a plurality of signals that are at least duplexed, the logic circuit compares the output signals of the function blocks, and detects an error on the basis of results of the comparison. The logic circuit comprises synthesizing means provided to superimpose inherent waveforms assigned in advance to the respective output signals of the function blocks onto the output signals of one of the function blocks. The inherent waveforms are orthogonal waveforms generated by an orthogonal waveform generator circuit. The logic circuit also comprises comparison means for comparing a signal output of the synthesizing means with the signal output of the other function block to detect an error. The whole circuit including the function blocks are judged normal only if the waveforms inherent to both output signals exist.

A control of a flash memory includes control for supplying a pulse-shaped voltage to each of non-volatile memory cells until a threshold voltage of the non-volatile memory cell having a first threshold voltage is changed to a second threshold voltage. The control involves a first write mode (coarse write) in which the amount of change in threshold voltage of each non-volatile memory cell, which is varied each time the pulse-shaped voltage is applied, is relatively rendered high, and a second write mode (high-accuracy write) in which the amount of change in threshold voltage thereof is relatively rendered low. As compared with the high-accuracy mode, the number of pulses required to change the threshold voltage of each memory cell is smaller than that in the coarse write mode. Therefore, the number of verify operations at the time that the coarse write mode is used, is small and hence the entire write operation can be speeded up.
