Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain an electronic balance which is comparatively inexpensive and has a high digital resolution by providing an integration circuit, etc., for time-integrating the output of a balance stem displacement detector. SOLUTION: The rotational displacement of a balance stem 1 due to a load to be measured is detected by a displacement detector 4, and an amplifier 11 amplifies the output of the detector 4, then an integration circuit 12 time- integrates the output of the detector 4. An addition circuit 13 adds the output of the circuit 12 to that of the amplifier 11, and an A/D concerter 14 digitizes the output of the circuit 13. A digital PID(proportion, integration, differentiation) computing means 15 performs PID operation per every cycle by using the output of the converter 14 as an input variable and determines the level of a feedback current to be applied to a solenoid coil 2. Thus, even a minute displacement detected value that cannot be resolved by the converter 14 is picked up as a parameter for digital PID computation, so that any error of quantization hardly occurs even when the converter 14 with comparatively low resolution is used.

Filed: 1995-07-26
Abstract: PURPOSE: To properly and surely execute the recovery operation and form stable and high-quality images at all times by setting a controlling means for controlling a recovery means based on results by a detecting means, a counting means and a measuring means. CONSTITUTION: When a main process is started, an execution number of times N for recovery operation after an ink container is exchanged is read from a counter 41. A read instruction is reset every time the ink container is exchanged. Moreover, the recovery operation is automatically conducted in the first place (N=1) every time an ink part is exchanged. A current time (t) is read from a timer 42, and then a time t0 read when the precedent discharging of final ink is finished is subtracted from the current time (t). The obtained value (t-t0 ) and a value t1 corresponding to the number of times N are compared each other. When the resulting value satisfies the formula, the recovery operation is automatically executed. After the execution, the normal discharging operation is carried out.  If the formula is not satisfied, the recovery operation is not carried out, but the normal discharging operation is performed.
