摘要： In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an initializing period for causing initializing discharge in a discharge cell, an address period for selectively causing address discharge in the discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. A holding period when discharge is not caused is disposed before the head subfield belonging to at least one subfield group of the plurality of subfield groups. In the initializing period of the head subfield belonging to at least one subfield group, an initializing operation of causing initializing discharge is performed in the discharge cell where the sustain discharge has been performed in the sustain period of the immediately preceding subfield.

摘要： The liquid discharging device includes a driving mechanism that drives a needle, a measurement plunger member and an inlet valve members that are concentrically-arranged inside a container. The driving mechanism includes: a piezoelectric-element support plate to which piezoelectric elements are attached; a spring for biasing the piezoelectric-element support plate toward a discharge outlet; and a control device adapted to control the piezoelectric elements separately. The piezoelectric-element support plate includes: a base end to which first end sides of the piezoelectric elements are fixed; a drive unit to which second end sides of the piezoelectric elements are fixed; and a displacement expanding portion expanding and outputting a displacement of the drive unit, the drive unit being displaced in conjunction with a expansion and contraction driving of the piezoelectric elements. Since the three members can be driven by the two piezoelectric elements, a driving at high speed can be realized and the liquid discharging device can be easily downsized.

摘要： The present invention provides a plasma display panel and a method for driving the plasma display panel each of which ensures to suppress problems associated with an erroneous discharge resulting from accidental occurrence of a strong discharge in a reset period as well as with an address discharge delay. The problems are suppressed without applying an auxiliary erase pulse after the reset period ends. As a result, image display is provided with no flickering and good quality. The reset period includes a first step of applying a voltage having an ascending ramp waveform and a second step of applying a voltage having a descending ramp waveform. Between the first and second steps, a potential change waveform having a rise or fall (voltage change pulse) is applied at least to scan electrodes, sustain electrodes, or address electrodes.

摘要： During each set-up period, wall charges of scan electrodes and sustain electrodes, between which sustain discharges were generated in the previous subfield, are adjusted, and parts toward the sustain electrodes of positive charges in the scan electrodes are replaced by negative charges and parts toward the scan electrodes of negative charges in the sustain electrodes are replaced by positive charges. During each address period, write pulses are applied to the scan electrodes to generate write discharges utilizing priming discharges between the scan electrodes and priming electrodes. During each sustain period, positive charges are accumulated in the entire surfaces of the scan electrodes and negative charges are accumulated in the entire surfaces of the sustain electrodes.

摘要： Provided are a PDP device and a drive method thereof which restrict the generation of an erroneous discharge in the all-cell reset period and to restrict the appearance of flickers in the areas with low grayscale levels even if some areas have a lower firing voltage than the other areas due to variation of a property in the panel surfaces or due to a long-term driving, or even if the voltage applied to the address electrode is increased with the pursuit of high definition.The pulse Pul.3 is applied to address electrodes Dat at timing t0 prior to timing t1 when the potential of the scan electrodes Scn is increased to Vq(V). In this drive method, voltage Vx(V) is applied to address electrodes Dat so that there is no potential difference between the scan electrodes Scn and the sustain electrodes Sus at timing t0 when discharge Dis.3 is generated. Accordingly, the discharge Dis.3, which is generated between the scan electrodes Scn and the sustain electrodes Sus due to reduction in the firing voltage, does not become a trigger for extending to the scan electrodes Scn to generate an erroneous discharge.

摘要翻译： 本发明提供一种限制全电池复位期间发生错误放电的PDP装置及其驱动方法，即使某些区域的点火电压低于低电平，也限制了灰度级低的区域的闪烁状态 由于面板表面的特性变化或由于长期驱动而导致的其它区域，或者即使施加到寻址电极的电压随着追求高清晰度而增加。 当扫描电极Scn的电位增加到Vq（V）时，在定时t1之前的定时t0将脉冲Pul.3施加到寻址电极Dat。 在这种驱动方法中，电压Vx（V）被施加到寻址电极Dat，使得当在产生放电Dis.3时在定时t0处扫描电极Scn和维持电极Sus之间没有电位差。 因此，由于降低烧制电压而在扫描电极Scn和维持电极Sus之间产生的放电Dis.3不会成为延伸到扫描电极Scn以产生错误放电的触发器。

摘要： A method of driving a plasma display panel including discharge cells, each at an intersection of a scan electrode and a sustain electrode, and a data electrode. One field period is divided into a plurality of sub-fields, each having an initializing period, writing period, and sustaining period. The sustaining period of at least one sub-field has a first sustaining period and second sustaining period. In the first sustaining period, a sustain pulse has a first leading edge duration. In the second sustaining period, the sustain pulse has a second leading edge duration shorter than the first leading edge duration. The second sustaining period is included at least at the end of the sustaining period.

摘要： In a steering apparatus for a vehicle, a target sub steering angle θSREF is set by target-sub-steering-angle setting means on the basis of an output θH of steering-wheel-angle detection means and a transmission characteristic f(θH) of transmission-characteristic setting means, and a target current IREF is set by target-current setting means on the basis of the target sub steering angle θSREF and an output θS of sub-steering-angle detection means. Current control means controls a current which flows through an electric motor of a sub-steering-angle superposition mechanism, so that the target current IREF and a current Is of current detection means may agree.

摘要： Barrier ribs are disposed on a back substrate so as to separate main discharge cells formed of a display electrode pair and a data electrode which face each other and priming discharge cells formed of a clearance between two adjacent scan electrodes. The top parts of the barrier ribs are formed so as to abut on a front substrate. In a driving method, in an odd-numbered line writing time period, scan pulse Va is sequentially applied to odd-numbered scan electrode SCp and voltage Vq is applied to even-numbered scan electrode SCp+1 to cause priming discharge between scan electrode SCp+1 and odd-numbered scan electrode SCp. In an even-numbered line writing time period, scan pulse Va is sequentially applied to even-numbered scan electrode SCp+1 and voltage Vq is applied to odd-numbered scan electrode SCp to cause priming discharge between scan electrode SCp and even-numbered scan electrode SCp+1.
