摘要： A power supply circuit for supplying a load, which may be a SMA component or a piezoelectric component, may use short high-voltage pulses to achieve fast heating of the load and, in order to comply with functional requirements, the SMA or piezoelectric component should not be supplied by connecting it directly to an electric line at a relatively high voltage. It is also disclosed an actuator comprising a power supply circuit of this disclosure and at least one load, comprising at least one smart materials chosen between a piezoelectric device and a a shape memory alloy (SMA) component, and a method of supplying a load comprising the steps of: connecting the AC to DC voltage converter of the power supply circuit to the AC mains by closing the input switch for charging a tank capacitor of the converter and, at the same time, opening the output switch for disconnecting the load from the tank capacitor: disconnecting the AC to DC voltage converter of the power supply circuit from the AC mains by opening the input switch and, at the same time, closing the output switch to supply the load by discharging the tank capacitor.

摘要： The present invention relates to a multi-stage vacuum equipment, preferably a two-stage equipment, whose normal operation requires different pressures to be set, wherein the pressure variation may be achieved by a Shape Memory Alloy (SMA) wire movement of a suitable element. The invention further discloses a method for operating said multi-stage vacuum equipment controlled by a SMA actuator.

摘要： A getter pump is described. The getter pump has a casing, whose shape is a solid of revolution with a revolution axis, and a plurality of getter cartridges mounted within the getter pump casing, each cartridge having a linear central support and spaced getter elements mounted on the linear central support. A getter cartridge orientation plane containing the linear central support and parallel to the revolution axis, and a getter cartridge positioning plane orthogonal to the revolution axis and intersecting the midpoint of a linear central support are defined. For each cartridge, the angle formed by the getter cartridge positioning plane with the linear control supports is equal to or less than 30°.
