摘要： A semiconductor wafer baking apparatus includes a hot plate, a container of which an upper part is open, and a cover that covers the upper part of the container. The cover includes an upper plate, a lower plate and a side wall that form a gas circulating space therebetween. At least one gas inlet is formed in the side wall, a plurality of gas supply holes are formed in a central region of the lower plate, and a skirt on which is formed a gas exhaust unit is coupled to a lower edge of the cover.

摘要： A piezoelectric inkjet head includes a plurality of pressure chambers filled with ink that is to be ejected, a manifold to supply ink to the pressure chambers and extending in both sides of each of the pressure chambers parallel to a direction in which the pressure chambers are arranged, a restrictor to connect the manifold to each of the pressure chambers, and to be connected to both ends of each of the pressure chambers in a longitudinal direction, a plurality of piezoelectric actuators respectively corresponding to the pressure chambers, and at least one nozzle respectively connected to each of the pressure chambers, and to be symmetrically arranged with respect to the centerline in a longitudinal direction of each of the pressure chamber. The at least one nozzle includes a first nozzle and at least two second nozzles, the first nozzle is disposed to correspond to the centerline in the longitudinal direction of each of the pressure chambers, and the second nozzles are disposed in both sides of the first nozzle.
摘要翻译：一种压电式喷墨打印头，包括：多个压力室，填充有要喷射的油墨;多个歧管，用于将油墨供应到压力室，并且在每个压力室的两侧平行于压力室排列的方向延伸连接歧管到每个压力室的限制器，并且连接到纵向方向上的每个压力室的两端，分别对应于压力室的多个压电致动器和至少一个喷嘴连接到每个压力室，并且在每个压力室的纵向方向上相对于中心线对称布置。所述至少一个喷嘴包括第一喷嘴和至少两个第二喷嘴，所述第一喷嘴设置成对应于每个压力室的纵向方向上的中心线，并且所述第二喷嘴设置在所述第一喷嘴的两侧。
