摘要:
In the initializing period of each of sub-fields comprising one field, one of all-cell initializing operation and selective initializing operation is performed. The all-cell initializing operation causes initializing discharge in all the discharge cells for displaying an image. The selective initializing operation selectively causes initializing discharge only in the discharge cells subjected to sustaining discharge in the preceding sub-field. Provided in the all-cell initializing period is an abnormal charge erasing part in which application of a rectangular waveform voltage to the scan electrodes causes self-erasing discharge in the discharge cells having excessive wall voltage accumulated therein.

A tire structural member manufacturing method forms a tire structural member from a narrow continuous strip by small, inexpensive equipment capable of being directly combined with a tire structural member forming machine, and a tire structural member manufacturing system carries out the tire structural member manufacturing method. The tire structural member manufacturing methods consists of a small number of steps and can be carried out by an efficient, simple, inexpensive tire structural member manufacturing system. The tire structural member manufacturing method forms a tire structural member by the steps of continuously forming a continuous strip of a width including that of a joint lap, cutting the continuous strip into successive cut strips of a length substantially equal to the section width of a tire, and successively laying and joining a predetermined number of the cut strips. The tire structural member manufacturing method forms a tire structural member also by the steps of continuously feeding a continuous strip to a strip-laying head, laying the continuous strip on a strip support while the strip-laying head is moved over the strip support for a forward stroke, cutting the continuous strip in a cut strip of a predetermined length when the strip-laying head reaches a position near the terminal of its forward stroke, changing the position of the strip-laying head by moving the strip-laying head and the strip support relative to each other, laying the continuous strip on the strip support while the strip-laying head is moved for a backward stroke, and repeating those steps overlap cut strips.

A method of driving a plasma display panel including a plurality of priming electrodes. The pulse width of scan pulses applied to some of a plurality of scan electrodes in which writing is performed and priming discharge is caused with the scanning of the scan electrodes is larger than the pulse width of scan pulses applied to the other scan electrodes in which writing is performed but no priming discharge is caused with the scanning of the scan electrodes.

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 a second sustaining period. In the first sustaining period, a transition period of a sustain pulse applied to the scan electrode is not temporally overlapped with a transition period of a sustain pulse applied to the sustain electrode. In a second sustaining period, a transition period of the sustain pulse applied to the scan electrode is temporally overlapped with a transition period of the sustain pulse applied to the sustain electrode. The second sustaining period is included at least at the end of the sustaining period.

A solid state relay comprises a light-emitting diode (2) for generating radiation in response to forward current supplied thereto and an array (5) of photodiodes optically coupled to the light-emitting diode for generating a voltage in response to radiation from the light-emitting diode. A thyristor (18) is provided having anode and cathode coupled to the gate and substrate electrodes (11a, 11b, 14a, 14b) of a field-effect transistor, respectively. A gate electrode (21) of the thyristor is connected to one end (7) of the photodiode array (5) and the cathode of the thyristor is further connected to the other end (8 ) of the photodiode array. The voltage generated by the photodiode array is applied to the switching transistor (9, 10) through a diode (17) so that the impedance between the source and drain electrodes of the transistor has a low value in the presence of the voltage and a high value in the absence of the voltage. A voltage photogerated by the array in response to radiation from the light-emitting diode forwardly biases the diode (7) and backwardly biases the thyristor, so that it is applied to the transistor without loss of energy. Upon cessation of the radiation, a voltage difference between the photodiode array and the transistor backwardly biases the diode (7) and forwardly biases the thyristor, providing a low impedance path for rapidly discharging energy stored in the transistor to cause it to turn off.
