20140252918 | Piezoelectric Power Generating Device - A piezoelectric power generating device that includes a piezoelectric element having a first surface and a second surface opposite the first surface, a stopper, and a lever. The stopper has a first contact surface that is in contact with the first surface. The lever includes a contact portion, which includes a second contact surface that is in contact with the second surface, and a displacement portion. The lever is arranged in such a manner as to be rotatable relative to the stopper around a rotation axis such that the second contact surface presses the second surface when the displacement portion rotates relative to the stopper around the rotation axis. | 09-11-2014 |
20140248535 | ELECTRODE ACTIVE MATERIAL , ELECTRODE AND SECONDARY BATTERY - An electrode active material has, as a main component, a mixture of an organic compound containing a rubeanic acid and cyanomethanesulfonylamide. The rubeanic acid is represented by the following general formula: | 09-04-2014 |
20140092526 | DIELECTRIC CERAMIC AND SINGLE-PLATE CAPACITOR - A dielectric ceramic that contains, as its main constituent, a perovskite-type compound containing Ba and Ti, and, with respect to the Ti content of 100 parts by mole, contains Re1 (Re1 is at least one element of La and Nd) in the range of 0.15 to 3 parts by mole, Y in the range of 0.1 to 3 parts by mole, Mg in the range of 0.3 to 13 parts by mole, and Fe in the range of 0.01 to 5 parts by mole. | 04-03-2014 |
20130228463 | PIEZOELECTRIC SHEET, METHOD FOR MANUFACTURING PIEZOELECTRIC SHEET, AND MANUFACTURING APPARATUS - A specific region of a polylactic acid sheet is heated by a microwave. To allow the polylactic acid sheet to exhibit piezoelectricity in the thickness direction of the polylactic acid sheet, a high voltage is applied to the heated polylactic acid sheet in the thickness direction of the polylactic acid sheet, and thereby the screw axes of at least a part of the polylactic acid molecules are relatively aligned with the thickness direction. Then the polylactic acid sheet is rapidly cooled, and thereby the polylactic acid molecules are immobilized. The same step is executed for other regions of the polylactic acid sheet, and thereby piezoelectricity is imparted to a wide area of the polylactic acid sheet in the thickness direction. The resultant piezoelectric sheet is capable of exhibiting a high piezoelectricity in the thickness direction. | 09-05-2013 |
