Patent number: 6932030Abstract: Described herein is a microgenerator of electrical energy with a high power density, which uses an internal-combustion micromotor with two combustion chambers set opposite to one another, within which a piston is displaced with reciprocating motion. The piston is at least in part made of magnetic material and is wound with a coil, within which is generated an electric current by induction. The fuel, the oxidant, and preferably a catalyst, are injected into each of the two combustion chambers by means of injectors that are substantially of the same type as those used in ink-jet printer heads. The dimensions of the device are comparable to those of a 1.5-V NiCd battery of a traditional standard type.Type: GrantFiled: May 6, 2003Date of Patent: August 23, 2005Assignee: C.R.F.

Patent number: 6762669Abstract: A shape memory actuator includes a shape memory actuator element for biasing an actuated member from an initial rest position to an operative position against the action of return spring means. Holding means are associated with the actuator element for holding the actuated member in its operative position even when the shape memory actuator element is deactivated. These holding means can be deactivated with a subsequent activation of the shape memory actuator element, allowing the actuated member to return to its rest position.Type: GrantFiled: March 18, 2002Date of Patent: July 13, 2004Assignee: C.R.F.

Patent number: 5058967Abstract: In an apparatus for manipulating laser beams with mirrors, the beam is caused to emerge substantially in alignment with the initial direction of the incoming beam by deflecting the incoming beam with a first mirror whose position is selectively adjustable to a second mirror which preferably has a parabolic surface, and then from the second mirror the beam is directed to a third, flat mirror whose position is also adjustable so that the beam is focussed on the region to be treated in a position substantially in alignment with the initial direction of propagation. An improved system for supplying screening gas to the region under treatment is also disclosed.Type: GrantFiled: April 30, 1990Date of Patent: October 22, 1991Assignee: Comau S.p.A.Inventors: Bartolomeo Pairetti, Giorgio Marinoni
