摘要： A preparation method for a piezoelectric fiber is provided including a piezoelectric functional layer and an insulating layer coated on the piezoelectric functional layer. The piezoelectric functional layer includes a piezoelectric composite layer of a spiral winding structure, and the piezoelectric composite layer includes a first piezoelectric layer, a conductive layer and a second piezoelectric layer that are sequentially stacked. The preparation method includes taking one end of the piezoelectric composite layer as a winding axis, winding the piezoelectric composite layer in a direction perpendicular to the winding axis to form the piezoelectric functional layer, wherein turns of winding the piezoelectric composite layer are greater than 5, coating the piezoelectric functional layer with the insulating layer, and vacuum heating to consolidate, to prepare a preform rod.

摘要： An apparatus 10 for poling piezoelectric material includes a platen 22 which holds a sample 20 of piezoelectric material to be poled and a stage 30 to which the platen is mounted. The stage 30 is arranged to selectively move the platen 22 and thereby the sample 20 which the platen 22 holds. The platen 22 is movable by the stage 30 selectively between a first position and a second position. A corona source 40 generates a corona to which the sample 20 is exposed when the platen 22 is moved to the first position by the stage 30. An electrostatic voltmeter 60 having a probe 62 measures a surface potential of the sample 20 when the platen 22 is moved to the second position by the stage 30.

摘要： A vibrator includes: a base portion; a vibrating arm including an arm portion which extends from the base portion, and a weight portion which is located on a tip end side of the arm portion and which has a first main surface and a second main surface that are in a front-back relationship; and a weight film disposed at the first main surface of the weight portion. The first main surface includes a planar surface and an inclined surface inclined with respect to the planar surface. A method for manufacturing a vibrator includes: a preparation step of preparing the above-described vibrator; and a removing step of removing a part of the weight film by emitting an energy ray to the weight film. In the removing step, the weight film disposed at the planar surface is removed and the weight film disposed at the inclined surface is not removed by emitting the energy ray to the weight film from a normal direction of the planar surface.

摘要： An ultrasound probe has an acoustic window (10) or lens (20) through which ultrasound is transmitted and received by a transducer array (30) located behind the lens or window inside a probe enclosure. The external, patient-contacting surface (24) of the acoustic lens or window is textured. The texturing of the surface of the lens or window better retains gel spread over the lens or window for an ultrasound procedure, reduces reverberation artifacts, and diminishes the appearance of scratches on the lens or window.
