摘要:
A friction drive belt for transmitting power while being wound around a pulley such that a compression rubber layer provided on an inner periphery of a belt body is in contact with the pulley enables both of noise reduction during the run of the belt and greater durability. A plurality of pores 15 having an average size of 5-120 μm are formed in the compression rubber layer 12 such that the compression rubber layer 12 has an air content of 5-40%.

摘要:
A priming discharge is generated simultaneously in two adjacent priming discharge cells, and an address operation is performed sequentially in the main discharge cells in the odd rows of the four rows of main discharge cells which are adjacent to the priming discharge cells. After completion of the address operation in all main discharge cells in the odd rows, the priming discharge cells are once initialized. A priming discharge is generated again in the priming discharge cells, and an address operation is performed sequentially this time in the main discharge cells in the even rows which are adjacent to the priming discharge cells. This provides a PDP and a plasma display device which can stably generate an address discharge without narrowing the driving voltage margin of an address operation and reduce the number of driving circuits required for driving the priming electrodes, and also provides a method for driving the PDP.
摘要:
A method of driving a plasma display panel having display electrode pairs each one of which pairs is formed of a scan electrode and a sustain electrode. A priming electrode is placed in every other spaces between the display electrode pairs and in parallel with the display electrode pairs. An addressing period includes an odd-line addressing period in which an address operation is conducted to primary discharge cells having odd-number scan electrodes, an even-line addressing period in which an address operation is conducted to primary discharge cells having even-number scan electrodes. During the respective addressing periods, scan pulse voltage Va is applied to odd-number scan electrodes or even-number scan electrodes while priming pulse voltage Vp is applied, prior to the application of the scan pulse voltage, to a priming electrode adjacent to the scan electrode to which scan pulse voltage Va is to be applied, in order to generate a priming discharge between the priming electrodes and the data 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:
Plasma display panel (PDP), PDP display apparatus, and method for driving the PDP. The PDP is a surface discharge AC PDP having a first substrate and a second substrate arranged to face each other with barrier ribs interposed therebetween. A first electrode and a second electrode are arranged on a facing surface of the first substrate so as to extend parallel to each other, and are covered with a dielectric layer. A third electrode is arranged on a facing surface of the second substrate so as to extend orthogonally to the first and second electrodes. A discharge gas is enclosed within a discharge space defined between the interposed barrier ribs. In the above PDP, the discharge gas is a gas mixture containing xenon. The xenon component comprises at least 5 vol % and less than 100 vol %, and has a partial pressure of at least 2 kPa. Furthermore, the gap between the first and second electrodes in the PDP is greater than a height of the discharge space.
摘要:
A plasma display panel has address properties stabilized. A priming discharge is performed between auxiliary electrodes (18), which are formed on a front substrate (1) and coupled with scan electrodes (6), and priming electrodes (14) formed on a back substrate (2). And on the front substrate (1), a dielectric layer (4) is made thinner in regions corresponding to priming cells (gap parts 13) than in regions corresponding to cell parts (11). As a result, the priming discharge has a wider margin, and a supply of priming particles to the discharge cells is stabilized, whereby a discharge delay during the addressing is reduced, and the address properties are stabilized.

A priming discharge is performed between auxiliary electrodes (17), which are formed on a front substrate (1) and coupled with scan electrodes (6) and priming electrodes (14) formed on a back substrate (2). Furthermore, a material layer (5) containing at least one of alkali metal oxide, alkaline earth metal oxide and fluoride is provided on regions corresponding to priming discharge spaces (30) (gap parts 13) on the back substrate (2). As a result, the priming discharge has a wider margin, and a supply of priming particles to the discharge cells is stabilized, whereby a discharge delay during the addressing is reduced, and the address properties are stabilized.

Barrier ribs are disposed on a back substrate so as to separate main discharge cells and priming discharge cells, and 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 sustain electrode SUp+1 to cause priming discharge between even-numbered sustain electrode SUp+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 sustain electrode SUp to cause priming discharge between odd-numbered sustain electrode SUp and even-numbered scan electrode SCp+1.

摘要:
The initializing period of at least one of a plurality of sub-fields constituting one field is a selective initializing period for selectively initializing discharge cells in which sustain discharge has occurred in the sustaining period of the preceding sub-field. In the sustaining period of the sub-field prior to the sub-field including the selective initializing period, voltage Vr is applied to a priming electrode (PRi) for causing discharge between the priming electrode (PRi) and corresponding scan electrode (SCi) using the priming electrode (PRi) as a cathode.
