A liquid ejection head includes therein a movable member, wherein the movable member is formed of lamination of at least three layers, at least one layer thereof having a free edge part covered with another layer.

In a method for fabricating an organic electroluminescent display, a first electrode layer is formed on a transparent substrate, and a hole transport layer is formed on the first electrode layer. After an organic luminescent layer is formed on the hole transport layer by scanning a donor film disposed on the substrate using a laser beam, the donor film is removed and then a second electrode is formed on the organic luminescent layer. The laser beam dithers while performing the scanning operation to make the energy distribution uniform.

The invention relates to a method for improving the laser patterning processing uniformity, and belongs to the technical field of laser application. According to the method for improving the laser patterning processing uniformity, a to-be-processed pattern is disassembled into a series of sub-patterns by adopting an interlacing splitting method, a phase diagram of each sub-pattern is calculate according to a Fourier iterative algorithm, then the phase diagrams are sequentially loaded into a spatial light modulator to obtain shaping light fields, the sub-pattern corresponding to each shaping light field is processed on a material by using the shaping light fields, and the sub-patterns are finally combined into the complete processing pattern. In this way, the problem of uneven energy deposition caused by spot noise of the light field when a single phase diagram is adopted for carrying out laser space light field shaping processing is solved, and then the purpose of improving the laser patterning processing uniformity is achieved. The method is simple in principle, the uniformity of a processing result is remarkably improved, and the method has strong practicability; and the method for improving the energy deposition uniformity by performing interlacing splitting on the to-be-processed pattern can play an important role in laser space light field shaping and patterning processingbased on the spatial light modulator.

The invention discloses an automatic weft finding device for a rapier loom. The automatic weft finding device comprises a weft sensor, a warp let-off mechanism, a reeling mechanism, a fluffing mechanism, an opening mechanism and a controller. The warp let-off mechanism, the reeling mechanism, the fluffing mechanism and the opening mechanism are provided with four variable frequency motors, respectively. The input end of the controller is connected with the weft sensor. The output end of the controller is connected with the four variable frequency motors; the controller is further connected with a stack storage. The invention further discloses an automatic weft finding method for the rapier loom. If weft breakage occurs, weft finding is performed at low equipment speed through a reversing program. The automatic weft finding device and method has the advantages that the defects of the prior art can be overcome, the structure of the rapier loom is simplified, and failure rate is reduced.
