摘要:
A double feed detection method for detecting whether sheet materials are double fed or not, includes the steps of applying an external force to a sheet material by bringing an external force into contact with the sheet material, detecting the external force applied to the sheet material, and determining whether the sheet materials are double fed or not using a signal obtained from the detection step.
摘要:
An electrode substrate comprises a backing substrate carrying thereon a metal electrode layer and/or a recording layer, the layer or layers having a smooth surface area with a surface roughness of less than 1 nm by more than 1 &mgr;m2. The smooth surface of the metal electrode layer and/or the recording layer is formed by firstly forming the layer on another substrate having a corresponding smooth surface and then peeling the another substrate off the layer after the layer is bonded to the surface of the backing substrate, whereby the smooth surface profile of the another substrate is transferred to the surface of the layer formed on the backing substrate.
摘要:
A method of manufacturing a cantilever drive mechanism arranged in such a manner that a cantilever portion, in which a piezoelectric layer is disposed between electrode layers, and a circuit portion, which is positioned adjacent to the cantilever portion and which drives the cantilever, are formed on the same substrate. The method includes the steps of first forming the circuit portion and then forming the cantilever portion after the circuit portion has been formed.
摘要:
A cantilever type displacement element includes a piezoelectric film and an electrode provided on each face of the film to displace the film by convence piezoelectric effect. The electrodes are formed from platinum or palladium. The displacement element constitutes a cantilver type probe having a tip on the free end of the element. The probe is used in a scanning tunneling microscope or an information processing apparatus.
摘要:
A probe of torsion lever structure is provided with a flat-plate driving unit formed on a substrate with a gap therebetween, two beams positioned along a straight line parallel to the substrate and rotatably supporting the flat plate-shaped driving unit relative to the substrate, a drive device for driving the flat plate-shaped driving unit, and a tip for information input/output provided at an end of the flat plate-shaped driving unit. The two beams are provided at a position between the end of the flat plate-shaped driving unit and the other end thereof, closer to the other end than the center between the end and the other end of the flat plate-shaped driving unit.
摘要:
When the initial displacement greatly varies among cells in an element, there is a need to reduce a bias voltage to be applied between electrodes. This decreases the sensitivity. An electromechanical transducer of the present invention includes an element having a plurality of cells. Each of the cells includes a first electrode and a second electrode that are provided with a cavity being disposed therebetween. A groove is provided at a position at a predetermined distance from the cavity of the cell on the outermost periphery of the element.
