摘要： In a driving method of a plasma display panel of the present invention, plural display electrode pairs are divided into plural display electrode pair groups and one field is divided into plural sub-fields. The length of the sustain period is compared to the length of the erase period. If the sustain period is longer than the erase period, sustain discharge and erase discharge are performed for each of the display electrode pair groups, while if the sustain period is shorter than the erase period, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group. For a sub-field with a largest luminance weight or a sub-field with a highest lighting ratio, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group without fail.

摘要： The present invention aims to improve a low gradation expression ability by reducing the brightness of the 1st gradation level to about 1.05 cd/m2 of the intermediate brightness between the 0th gradation level and the 2nd gradation level at the time of driving a PDP. During a sustain erase period (P13) of a subfield (SF1) with the smallest brightness weight among a plurality of subfields (SF), a positive voltage (Vbk) that is smaller than a voltage (Vsus) applied during a sustain period (P23) of other SFs is applied to scan electrodes. Also, during the sustain erase period (P13) of SF1, a positive voltage (Vda) is applied to address electrodes or a positive voltage (Vda) is applied to the address electrodes during at least one period of a voltage rising period (T11) of an all-cell reset period (P11).

摘要： The purpose of the present invention is to provide a method for accurately dropping molten metal that flows from a ladle into a pouring gate in a mold. The present invention includes a method for controlling the respective input voltages transmitted to a servomotor that tilts the ladle such that the molten metal that flows from the ladle drops accurately into the pouring gate in the mold, a servomotor that moves the ladle back and forth, and a servomotor that moves the ladle up and down, by using a computer. In the method, a mathematical model of the area on which the molten metal that flows from the ladle will drop is produced, and then the inverse problem of the produced mathematical model is solved. In view of the effect of a contracted flow, the position on which molten metal drops is estimated by the estimating device for estimating the pouring rate and the estimating device for estimating the position on which molten metal will drop. Then the estimated position is calculated by a computer. Thereby the respective input voltages transmitted to the servomotor that tilts the ladle, the servomotor that moves the ladle back and forth, and the servomotor that moves the ladle up and down, are obtained. Then the three respective servomotors are controlled based on the obtained input voltages.
