摘要： Nozzle groups are arranged in a staggered pattern such that dead space does not occur. However, gaps are opened up between actuator units so that the actuator units can be joined to flow channel units. Further, piezoelectric elements are formed at each of the actuator units, and thus piezoelectric plates are consequently shorter. Therefore, when an inkjet recording head is lengthened, there is no need to form the piezoelectric elements by processing from a single long piezoelectric plate, implementation with a plurality of short piezoelectric plates is possible, and thus production yields do not deteriorate. Further, as the actuator units can be associated and arranged in a staggered pattern, an increase in width of the inkjet recording head can be minimized.
摘要翻译：喷嘴组以交错图案排列，使得不会发生死空间。然而，在致动器单元之间打开间隙，使得致动器单元可以连接到流动通道单元。此外，压电元件形成在每个致动器单元处，因此压电板因此更短。因此，当喷墨记录头被延长时，不需要通过单个长的压电板的加工来形成压电元件，因此可以实现多个短的压电板，从而生产率不会变差。此外，由于致动器单元可以以交错图案相关联并布置，所以喷墨记录头的宽度的增加可以被最小化。

摘要： An inkjet recording head includes a two-dimensional array of a pressure chambers and corresponding array of piezoelectric elements each for applying a pressure wave to ink in a corresponding pressure chamber. In fabrication, a piezoelectric plate temporarily bonded onto a substrate is subjected to sandblasting to form the plurality of piezoelectric elements. After the piezoelectric elements are bonded as a unit onto a diaphragm which constitutes part of the walls of the pressure chambers, the substrate is removed. Dummy patterns equalize the degree of side etching among the piezoelectric elements.

摘要： An operation control system for automated guided vehicles conveying articles along an unmanned conveying system. This operational control system comprises a first travel path loop and a second travel path loop along which a first group and a second group of the automated guided vehicles are automatically travelled. A common travel path is provided along which the automated guided vehicles of both the first and the second group are travelled, to enable a transfer of articles between the groups of automated guided vehicles. Also a correlating unit for correlating one automated guided vehicle of the first group with another automated guided vehicle of the second group, and a transfer control unit for controlling the transfer of the articles between the automated guided vehicles are provided. The transfer control unit permits only a transfer of articles between automated guided vehicles correlated with each other by the correlating unit.

摘要： An ink jet recording head is capable of: preventing any of stagnation in ink flow, formation of vapor bubbles, cavitation, or like problems from occurring in the ink flow; realizing an excellent ink ejection operation, and thereby realizing a high quality gradation expression in recording; and, lessening a degree of a required accuracy both in dimension and in alignment of its components being stacked together. In a method for manufacturing the ink jet recording head provided with a pressure generating chamber, this chamber is constructed of a through-hole of a chamber plate and a pair of plates, between which plates the chamber plate is sandwiched. The processing step for forming this through-hole further comprises the sub-steps of: forming a first resist film and a second resist film on a first and a second surface of the chamber plate, respectively, wherein the resist films assume substantially a same shape, but are different in length from each other when measured in a direction parallel to a flow direction of ink; and, etching away both the first and the second surface of the chamber plate using the resist films as its masks so that the through-hole is formed in the chamber plate and serves as the pressure generating chamber.

摘要： Opposing piezoelectric elements bordering a boundary between neighboring nozzle groups have point symmetry. Hence, even if a gap is opened up between actuator units due to necessity in assembly, rows of the nozzles are not offset. Accordingly, even a series of nozzle groups are combined in a conveyance direction of a recording medium, width of an inkjet recording head is not increased. Further, because the rows of nozzles are not offset, there is no requirement to offset discharge timings for each actuator unit, and output of image data does not become complex. Thus, lengthening can basically be implemented with two piezoelectric plates. Consequently, production yields can be improved.
摘要翻译：与邻近喷嘴组之间的边界相邻的压电元件具有点对称性。因此，即使在组装中由于必要性而在致动器单元之间打开间隙，喷嘴的行也不会偏移。因此，即使在记录介质的传送方向上组合一系列喷嘴组，喷墨记录头的宽度也不会增加。此外，由于喷嘴列不偏移，因此不需要对每个致动器单元的喷射定时进行偏移，并且图像数据的输出不会变得复杂。因此，可以基本上用两个压电板实现延长。因此，可以提高产量。
