Abstract: A carrier jet printer (40) includes an output characteristic conversion circuit (41) for converting an input signal that includes information on dots to be printed into a print signal that is necessary for printing by performing predetermined conversion processing on the input signal, and a printer head (30) for printing dots on a recording medium by forming an ink liquid for each dot by mixing ink and a dilute based on the print signal so that the density of the ink liquid corresponds to that of the dot, and jetting the ink liquid onto the recording medium. The output characteristic conversion circuit (41) converts the input signal into the print signal so that the printer head mixes the ink into the dilute even in a case where printing is performed based on an input signal that includes information on a dot of the lowest density.

Abstract: The overcharge preventing circuit for secondary batteries comprises overcharge detecting comparators (COMP2, COMP4), each having a hysteresis circuit (1), which are connected between positive and negative electrodes of series-connected secondary batteries (Abat, Bbat), and overdischarge detecting comparators (COMP1, COMP3), each having a hysteresis circuit (2), again connected beteween said electrodes. Transistors (T1, T2) and a resistor (R) are connected between the batteries for overflow of overcharge and balance of overdischarge. Upon detection of any over charge by the comparator COMP2 or COMP4, the charge current is interrupted by a transistor (T6). Simultaneously the overcharge overflow is discharged by the hysteresis circuit until the battery voltage is lowered to the hysteresis voltage. After the discharge, the transistor (T6) is turned on to resume recharging of the batteries. Upon detection of any overdischarge by the comparator COMP1 or COMP3, the discharge current is interrupted by a transistor (T5). Thus, the overcharge and the overdischarge can be balanced by the hysteresis said circuits (1,2, respectively).
