摘要： An apparatus for poling a piezoelectric ceramic includes a first and a second electrode which are connected to a DC power supply and spaced away from one another at a certain distance, and an insulated medium provided between the first and second electrodes. The second electrode is adapted to carry the piezoelectric ceramic which is spaced away from the first electrode. In this way, a piezoelectric ceramic can be poled by a poling field created between the first and second electrodes and prevented from being scraped by the first electrode or damaged by the ripples caused by an unstable voltage because of the separation of the piezoelectric ceramic to be poled from the first electrode and the buffering effect caused by the insulated medium between the first and second electrodes. In addition, the second electrode may be specifically in the form of a power-driven metal conveyor so that the piezoelectric ceramic to be poled can continuously pass through and be poled by the poling field.

摘要： A type of piezoelectric transformer (PT) which vibrates in length extensional mode is provided. The piezoelectric transformer (PT) has a piezoelectric substrate which has a first dimension, a second dimension and a third dimension with the first dimension being longest and the third dimension being shortest. The substrate has two polarization directions parallel to the first dimension near two terminals of the first dimension and at least two opposite polarization directions on a central portion of the substrate transversely to the first dimension. The substrate further has at least two electrodes on a portion horizontal to the first dimension. Comparing with traditional piezoelectric transformers, the new one can solve the polarization difficulties and reduce audio noise output without sacrificing the electrical properties or even have better voltage transformation characteristics.

摘要： A guiding device for wood cutting includes a positioning member, a guiding member, and a member for releasably securing the guiding member to the positioning member and allowing relative pivotal movement between the positioning member and the guiding member when in a released position. The positioning member includes a horizontal section, a vertical section extending downwardly along a longitudinal direction of the horizontal section so that the horizontal and vertical sections may abut against two adjacent sides of a wood piece to be cut. A first circular section extends longitudinally from an end of the positioning member, and a boss projects outwardly from an upper side of the first circular section. The guiding member includes a second vertical section for guiding a saw blade, a second circular section extending longitudinally from an end thereof and having a recess defined in an underside thereof for receiving the boss of the positioning member, thereby allowing relative pivotal movement between the positioning member and the guiding member. A plurality of annularly disposed holes are defined in one of the first and second circular sections, and at least one positioning protrusion projects from the other of the first and second circular sections for releasably engaging with the annularly disposed holes.

摘要： A touch pad operation method with multiple function modes, an integration system, and a computer program product are provided. A first signal is received and whether the first signal conforms to a trigger condition is determined. If the first signal conforms to the trigger condition and exists continuously, the touch pad is switched from a first function mode to a second function mode and maintained therein. The second function mode includes a plurality of functions of a second kind, and each of these functions is respectively corresponding to an area on the touch pad. When a second signal is received through the touch pad and the first signal still exists, one of the second kind of functions is executed according to a coordinate variation corresponding to the second signal. Thereby, the functionality of the touch pad is not limited by its original settings and the convenience of operation is increased.
