Abstract:
A reticle is designed with a method including generating first dummy patterns with intervals from main patterns. Each of the first dummy patterns are divided into a plurality of spaced apart second dummy patterns and then each of the second dummy patterns are measured to find third dummy patterns having widths and areas below smallest allowable values. The third dummy patterns are then respectively connected to second dummy patterns which are adjacent to the third dummy patterns by generating a connecting dummy pattern. Selective non-connected third dummy patterns are removed. The first dummy patterns are divided into a plurality of second dummy patterns by vertical and horizontal strip lines crossing the first dummy patterns.
Abstract:
An extension device 5 is engaged in a connector provided on one side of a lower case 102 of a cabinet 100 of an PIP apparatus PI. An adjustable foot 6 is provided on the bottom surface 102u to adjust the extension device 5 and the cabinet 100 in height. Therefore, the cabinet 100 can be horizontally placed on a plane. When the extension device 6 is approximately equal in height to the lower case 102, the adjustable foot is retracted into the lower case 102. Therefore, the thickness of the PIP apparatus PI can be minimized.
Abstract:
A thick planarization layer of silicon dioxide that is heat resistant is provided by coating a polysilazane layer over a substrate having steps and firing the polysilazane layer in an oxygen-containing atmosphere to convert the polysilazane to silicon dioxide. The temperature of this conversion may be as low as 400.degree. to 450.degree. C. while a higher firing or curing temperature is preferable to obtain a more densified oxide layer.
Abstract:
A core assembly for magnetizing a columnar permanent magnet, especially a columnar ceramic permanent magnet and a developing roll magnetized by the core assembly, adapted for use in an electrostatic developing apparatus of magnetic-brush developing type. The magnetizing iron core assembly has a specific arrangement of magnetic poles and magnetizing coil windings for providing a specific pattern of magnetic flux distribution which would provide the most efficient development.

Abstract:
A portable computer 1 has a first metallic portion 6 and a second metallic portion 7, and an expansion device 10 has a first magnet 16 and a second magnet 17, whereby the expansion device 10 can be attached to a predetermined position of the portable computer 1 using attractive forces generated by the magnets. Therefore, when the portable computer 1 to which the expansion device 10 is attached is dropped mistakenly on a floor, etc., and the impact is applied on the expansion device 10, the expansion device 10 is separated from the portable computer 1 easily. Thus, even if the expansion device 10 is damaged, the impact to be transmitted to the portable computer 1 can be reduced by separating the expansion device 10 from the portable computer 1, which reduces damage to the portable computer 1.
Abstract:
A method is provided for controlling an image processor to perform display of an image on a first display device in synchronization with short frames and to perform display of an image on a second display device in synchronization with long frames each of which has a time length longer than a time length of each short frame. According to the method, a synchronization signal acquisition process acquires a first synchronization signal synchronized with switching of the short frames. An estimation process estimates, each time the first synchronization signal is acquired, a generation position of a second synchronization signal synchronized with switching of the long frames within a 2-frame period corresponding to two short frames after the first synchronization signal is acquired. The image processor is provided with a drawing command instructing generation of an image to be displayed on the first display device or the second display device controllably in accordance with results of the estimating by the estimation process.
Abstract:
A plasma display panel (PDP) not only capable of reducing a discharge start voltage but also of making the discharge start voltage uniform in each cell without being adversely affected by the variations in the distance between electrodes caused during manufacture has been disclosed, wherein a pair of electrodes, provided in each of a plurality of cells respectively in which a discharge is caused to occur selectively for display in a discharge space, has facing edges, respectively, provided for discharge and the distance between the facing edges changes when viewed from a direction perpendicular to a substrate and the edges in each of the plurality of cells have substantially the same shape.
Abstract:
A PDP (plasma display panel) is manufactured by a manufacturing method including the steps of: (a) preparing a front structure (first structure) having a plurality of X electrodes (first electrodes) and Y electrodes (first electrodes) formed on one surface of a front substrate (first substrate) and a dielectric layer that covers the X electrodes and the Y electrodes and a rear structure (second structure) having a plurality of address electrodes (second electrodes) and a plurality of barrier ribs formed on one surface of a rear substrate (second substrate); (b) forming a protective layer containing SrCO3 (strontium carbonate) on a surface of the dielectric layer of the front structure; and (c) assembling the front structure and the rear structure, wherein the step (c) includes a transforming step in which the protective layer is formed by transforming at least a part of SrCO3 contained therein to SrO (strontium oxide).
