Abstract: A driving method and a driver circuit for improving the definition of display image on a plasma display device. In an initial state in an addressing discharge period, a scanning electrode is applied with a scanning base pulse at a first power supply potential. This suppresses a weak erroneous discharge between a scanning base pulse and a display data pulse. Next, the scanning electrode is applied with a scanning pulse. After the scanning pulse has been applied, the scanning electrode is applied with the scanning base pulse at a second power supply potential. In this way, the level of the scanning base pulse applied to the scanning electrode after the end of the application of the scanning pulse in the addressing discharge period is lower than the level of the scanning base pulse applied to the scanning electrode before the application of the scanning pulse.

Abstract: A charge-collecting circuit is connected between a clamping circuit on the side of the sustain electrodes and a clamping circuit on the side of the scan electrodes so as to be parallel to a capacitance between said sustain electrodes and said scan electrodes. In write-discharge, sustain-discharge, and the like, when a sustain-electrode potential staying at the level of the ground potential with a switch S2 being turned ON is to be increased to the level of the power potential that is the same as the level of a scan-electrode potential staying at the power potential with a switch S5 being turned ON, the switch S2 is first turned OFF, a current is then applied to flow from the scan-electrode to the sustain-electrode side to thereby slowly increase the potential on the side of the sustain electrodes in the charge-collecting circuit. Then, the switch S1 is subsequently turned ON, thereby, the sustain-electrode potential is clamped to the power potential at the same level as that of the scan-electrode potential.

Abstract: Two sustain driver circuits are provided: a first sustain driver circuit for both controlling the potential on the scan electrode side and effecting control such that, when the scan electrode side is at the power-supply potential, this potential is used to raise the potential on the sustain electrode side; and a second sustain driver circuit for both controlling the potential on the sustain electrode side and effecting control such that, when the sustain electrode side is at the power-supply potential, this potential is used to raise the potential of the scan electrode side. When the scan electrode side is at the power-supply potential, control is effected such that current flows from the first sustain driver circuit to the second sustain driver circuit by way of a third switching element and first coil, whereby the potential of the scan electrode side falls and the potential of the sustain electrode side rises.

The protection signal output circuit outputs a protection signal to the control circuit when sum of currents supplied from the data drivers to the data electrodes within a time equal to one sub-field or more to less than one frame exceeds a previously set first specified current value. The protection signal restrains the operation of the data drivers.

Abstract: A ball joint is disclosed having a socket, a ball received by the socket and a stud extending outwardly from the ball. A ball seat member is received in the socket and has a soft portion with an inner spherical surface which covers the portion of the ball at the side opposite to the stud. The soft portion is axially compressed by a cap closing an opening in the socket opposite to the stud, while expanding radially outward to be penetrated by linear projections formed in a hard portion of the ball seat member. Further, a gap remains between the soft portion after it has expanded radially outwardly and the inner cylindrical surface of the hard portion of the ball seat member so that the soft portion of the ball seat member contacts the hard portion of the ball seat member only at the linear projections.
