Control signals are input to the gates of a P-MOS transistor and an N-MOS transistor of a CMOS drive circuit from respective control signal generating sections. The CMOS drive circuit drives a piezoelectric member as a capacitive element and the piezoelectric element is used in an ink jet head. A substrate of the P-MOS transistor is provided with a voltage higher than a power supply of the CMOS drive circuit. A first potential difference is supplied between terminals of the piezoelectric element and thereafter, a second potential difference of a polarity opposite to the first potential difference is further supplied between the terminals. A discharge operation is inserted in a time period from the time when supply of the first potential difference is completed till the supply of the second difference gets started. The discharge operating time period is set to a proper value at which a desired operating speed, high reliability and low power consumption are achieved.

A method for immobilizing living microorganisms includes a step (1) of disposing a solution containing microorganisms as an electrolyte on the surface of a substrate at least one portion of which is an electrode, and applying a constant potential to the electrode to cause at least a portion of the microorganisms to attach to the surface of the substrate. The constant potential in step (1) is greater than −0.5 V but not greater than −0.2 V (vs Ag/AgCl) or greater than +0.2 V but not greater than +0.4 V (vs Ag/AgCl). The electrolyte in step (1) does not contain a source of nutrition for the microorganisms.

An input terminal inputs an input signal oscillating between a first power source voltage and second power source voltage according to a selected mode and a non-selected mode. An output terminal delivers a signal oscillating between the first and second power source voltages and a third power source voltage according to voltage conversion and non-voltage conversion. An N-channel E type transistor of a positive threshold voltage has a source electrode and a drain electrode connected between the input terminal and the output terminal and a gate electrode supplied with the second power source voltage. An N-channel I type transistor of a neutral threshold voltage has a source electrode and a drain electrode connected between the input terminal and the output terminal and a gate electrode supplied with a control signal oscillating between the first power source voltage and the second power source voltage, the control signal determining whether or not a voltage conversion is made. A charge pump circuit is connected to the output terminal and operative with the first, second and third power source voltages such that the charge pump circuit is rendered an active state only when the voltage conversion is mode. A predetermined number of level shifter circuits having an arrangement as set out above are connected between row and column decoders of an EEPROM on one hand and a cell matrix array on the other hand.

A sheet storing apparatus wherein sheets ejected from a copying machine one after another are stacked in order, and the sheets are supplied to the copying machine again. The apparatus comprises a sheet storing unit wherein sheets are stored, a transporter for transporting sheets to the storing unit, a regulator for preventing sheets supported by a sheet support surface of the storing unit from moving back toward the entrance thereof, a pressure member for pressing each sheet transported to the unit against the support surface and a refeeder for feeding out the stored sheets one by one. Each time a sheet is transported to the unit, the pressure member presses the sheet, whereby the end of the sheet passes through the regulator to be put between the support surface and the regulator. Also, in feeding sheets out of the unit, the pressure member presses the sheet stack against the refeeder. The pressure member has a mechanism for adjusting the pressure on the sheet stack in proportion to the thickness of the stack. Each time a sheet is transported to the unit, the timing of actuating the pressure member is determined, and the position of the pressure member is detected. When it is not detected that the pressure member is in a pressing position within a specified time after a timing signal was generated, a controller judges that a sheet jam has occurred.

A memory cell array includes a matrix array of a plurality of memory cells. These memory cells are non-volatile transistors. The memory cells which are arrayed in each row of the memory array, are coupled with a plurality of word lines. The word lines are selected by a row decoder made up of a plurality of partial decoders. In this case, a constant voltage output circuit, which is provided at the outputs of the partial decoders of the row decoder, outputs a constant voltage lower than a power source voltage to a corresponding word line of those word lines when the corresponding word line is selected by the outputs of the partial decoders.
