ABSTRACT:
A minimum per-time voltage-increase gradient during a time a driving voltage is being increased is not less than 1/8 a maximum per-time voltage-increase gradient during said time the driving voltage is being increased. A driving-voltage increase amount which the driving voltage is increased during a time, within a predetermined time, during which a per-time voltage-increase gradient is maintained at a maximum voltage is not less than 1/2 of a full driving-voltage increase amount which the driving voltage is increased during said predetermined time. When the driving voltage is decreased, a per-time voltage-decrease gradient when said voltage decrease is started is sharper than an average per-time voltage-decrease gradient, and a per-time voltage-decrease gradient when said voltage decrease is ended is less sharp than the average per-time voltage-decrease gradient. Further, a time during which a per-time voltage-decrease gradient is maintained less sharp than said average per-time voltage-decrease gradient is not less than 1/2 a full time during which the driving voltage is being decreased.
