摘要： Techniques and mechanisms to provide mechanical support for a micromachined piezoelectric transducer array. In an embodiment, a transducer array includes transducer elements each comprising a respective membrane portion and a respective supporting structure disposed on or around a periphery of that membrane portion. The transducer elements are initially formed on a sacrificial wafer, wherein supporting structures of the transducer elements facilitate subsequent removal of the sacrificial wafer and/or subsequent handling of the transducer elements. In another embodiment, a polymer layer is disposed on the transducer elements to provide for flexible support during such subsequent handling.

摘要： A piezoelectric device and method of manufacturing the same and an inkjet head are described. In one embodiment, the inkjet print head comprises a plurality of jets, wherein each of the plurality of jets comprises a nozzle, a pressure chamber connected with the nozzle, a piezoelectric body coupled to the pressure chamber, and an electrode coupled to the piezoelectric body to cause displacement of the piezoelectric body to apply pressure to the pressure chamber in response to a voltage applied to the electrode; and wherein electrodes of two or more of the plurality of jets have different sizes to cause their associated piezoelectric bodies to have a uniform displacement amount when the voltage is applied to the electrodes.

摘要： An information storage system includes a transducer having a loop of ferromagnetic material with pole tips separated by an nonferromagnetic gap located adjacent to a medium such as a rigid disk. During writing the separation between the pole tips and the media layer of the disk is a small fraction of the gap separation. Due to the small separation between the pole tips and the media layer, the magnetic field generated by the transducer and felt by the media has a larger perpendicular than longitudinal component, favoring perpendicular recording over longitudinal recording. The media may have an easy axis of magnetization oriented substantially along the perpendicular direction, so that perpendicular data storage is energetically favored. The transducer may also include a magnetoresistive sensor for reading magnetic information from the disk.
