A partition is formed by the process including a step for providing a sheet-like partition material that covers a display area and outside thereof on the surface of the substrate, a step for providing a mask for patterning that covers the display area and the outside thereof, so that a pattern of the portion arranged outside of the display area of the mask is a grid-like pattern, a step for patterning the partition material covered partially with the mask by a sandblasting process, and a step for baking the partition material after the patterning.

In a belt continuously-variable transmission, a casing or a housing is formed with an air communicating hole extending through an upper part of the casing or the housing. The casing and the housing include inner walls defining an air breather chamber and communicating parts. The air breather chamber is defined in a region located above a joint between the casing and the housing and ranging from an upper side of the second shaft to an upper side of the first shaft and between the second shaft and the first shaft. The communicating parts are defined at a position in the upper side of the first shaft and at a position between the second shaft and the first shaft. The air breather chamber communicates with open air via the air communicating hole, and communicates with an inside part of a casing assembly via each of the communicating parts.

First and second oil flow passages are defined in a wall portion of a transmission casing. The first oil flow passage has an open end exposed to an interior of the casing. The second oil passage is connected to the first oil passage through a connection opening defined by the first oil passage. A separate pipe member has a predetermined end portion that is inserted into the first oil passage from the open end of the same. The predetermined end portion comprises a cylindrical portion having a fixed length; an end opening defined by an end of the cylindrical portion and exposed to the first oil passage; and an orifice opening defined by a side wall of the cylindrical portion. The orifice opening is blocked by an inner wall of the first oil passage when the connection opening takes a first position relative to the open end of the first oil passage, and exposed to the second oil passage when the connection opening takes a second position relative to the open end of the first oil passage. The second position is closer to the open end of the first oil passage than the first position is.

Method for forming partitions of plasma display panel by using sandblasting process

In a conventional method of driving a plasma display panel, for example, an auxiliary discharge is executed between an A electrode and a Y electrode to improve light-emission efficiency of a display discharge. However, since a phosphor layer is present between the A electrode and the Y electrode, the phosphor layer is exposed to a discharge, whereby there is a problem that its characteristic deteriorates. A method of driving a plasma display panel having a structure, in which at least three display electrodes X, Y, and Z used for a display discharge are provided to a display cell and no phosphor layer is formed between said display electrodes and a discharge space, the method comprising the steps of: varying a potential of at least one display electrode Z of said display electrodes during said display discharge; and making a potential of said at least one display electrode Z at a time of starting said display discharge different from that at a time of ending said display discharge.

Plasma display panel driving method and plasma display apparatus

There is provided an oil separating structure of an automatic transmission, which makes it difficult for an oil strainer of an oil pump to draw oil containing air bubbles. A baffle plate base separates a space around the oil strainer and a space around a driven sprocket as well as a final gear, and therefore, oil containing air bubbles formed as a result of agitation by the driven sprocket, chain, and final gear does not flow directly into the oil strainer. As a result, the oil strainer is unlikely to draw oil containing air bubbles.

To maximize the efficiency of utilization of mother substrates used as material for the substrates in the flat display panel to form a display screen, the flat display panel includes a display screen formed by tetragonal first and second substrates. Four sides or opposite two sides forming a tetragonal peripheral edge of the first substrate are rendered to be substantially equal to those of the second substrate, and the first and second substrate are sandwiched together with one of the first and second substrates protruding in part outwardly from the peripheral edge of the other of the first and second substrates.

A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view.A plasma display panel includes two spaced substrates defining a gap therebetween. The gap is divided by intersecting walls into columns and rows of discharge cells. Portions of a wall that are lower in height than remaining portions of the wall define a flow path. The plasma display panel realizes a bright and stable display.

A belt-type continuously-variable transmission includes a casing enclosing a primary pulley, a secondary pulley, a belt connecting the pulleys and a parking gear; and a side cover subassembly including a side cover joined to the casing. The side cover assembly further includes a parking pawl arranged to engage with the parking gear, a support member arranged to support the parking pawl; and a return spring.

A driving method of a plasma display panel is provided in which effective resolution and luminance in a display of fields that constitute a frame are improved. The method includes dividing each of M (M&#x2267;2) fields that constitute a frame into K (K&#x2267;2) subfields having luminance weight, displaying the k (1&#x2266;k&#x3c;K) subfields selected in descending order of the luminance weight in progressive format using all display lines out of the K subfields and displaying the remaining subfields in interlaced format using the display lines selected at regular intervals at a ratio of one per M display lines in arrangement order.

A rib structure for a display device includes a light-transmissive rib structure containing therein a material absorbent of visible light so that a visible light absorption distance is 40 to 1200 &#x3bc;m (the visible light absorption distance L (&#x3bc;m) means a distance such that visible light decreases to exp(&#x2212;T/L) times less in connection to the travel distance T (&#x3bc;m), that is, visible light is absorbed by 1-exp(&#x2212;T/L)).

A method for driving a plasma display panel is provided in which wasteful power consumption is reduced and ion bombardment that may deteriorate cells is suppressed for a long life of cells. A ratio of lighting that is a ratio of the number of cells to be lighted to a total number of cells is detected in accordance with display data that determine contents of addressing. In accordance with the detected ratio of lighting, a waveform of a voltage pulse that is applied in the sustaining step for displaying the corresponding display data is changed so that a gradient of the voltage change at a leading edge becomes smaller for a large value of the ratio of lighting than for a small value of the same.
