Abstract: An electrically actuated positioning element system utilizes a positioning element formed of piezo-electrical bodies each formed of a plurality of lamellae having electrodes. The lamellae have a length substantially greater than their thickness and upon application of an electrical voltage with a field direction which promotes a polarization of the material of the lamellae, the body is shortened. The two bodies are connected to one another at one end by a cross arm and at the other end the one body end is active and free to move relative to the other body end such that a resultant relative motion occurring between the two body ends may be utilized. Preferably a connection is provided for absorbing a lateral thrust of the bodies. The two piezo-electrical bodies are each electrically connected to one another for reverse-phase operation such that one contracts while the other is in a lengthened condition and vice versa.

Abstract: A side pumped, fiber optic amplifier comprises an optical fiber (12), having a first refractive index, formed of a laser material, such as Nd:YAG. A jacket (14), which surrounds the optical fiber (12), has a second refractive index, lower than the first refractive index. This jacket (14) is cone shaped and tapers from a large end (16) to a small end (18). High power laser diodes are mounted on the large end (16) to produce collimated pump light to pump the optical fiber material. The cone shaped jacket (14) focuses this pump light to an interaction region at the small end (18), where the jacket material is quite thin, e.g. on the same order of magnitude as the diameter of the optical fiber (12). The focused light is absorbed by the optical fiber (12) in this interaction region, and causes an electronic population inversion in the laser fiber material. A signal propagating through the optical fiber (12) stimulates spontaneous emission from the optically excited laser material, thereby resulting in amplification of the signal.

Abstract: Patente de Invenção:<B>"CARTUCHO DE JATO DE TINTA RECARREGáVEL PELO USUáRIO E PROCESSO PARA FABRICAR O CARTUCHO"<D>. Um cartucho de jato de tinta não-recarregável é tornado regarregável pelo usuário de uma maneira conveniente. O cartucho de jato de tinta da Hewlett-Packard n 51626A é modificado pelo selar o suspiro na base do cartucho com uma fita adesiva autocolante, e remover o tampão de enchimento de tinta hermético no topo do cartucho. Após o recolhimento com tinta, uma garrafa inflatora do tipo de fole é usada para inflar as bexigas no interior do cartucho fazendo uso de uma abertura no cartucho. A abertura de encher com tinta é resselada quer imediatamente antes quer imediatamente após as bexigas serem infladas, e a garrafa inflatora é então removida, o que libera a pressão de ar nas bexigas, causando a desinflação das bexigas. As bexigas desinfladas causam uma área de pressão de ar reduzida a se formar sobre o nível de enchimento de tinta, o que impede a tinta de vazar do cartucho quando a fita adesiva autocolante cobrindo o suspiro na base do cartucho é removida.
