摘要： The invention relates to a defrosting device comprising an actuator (110) having a stationary portion (112) and a movable portion (114) designed to alternately move away from and move towards the stationary portion (112), and an intermediate element (124) comprising a loading portion (126) arranged so to be pushed by the movable portion (114) of the actuator (110) when the movable portion (114) of the actuator (110) moves away from the stationary portion (112), and a movement transmission portion (130) designed to move according to the movement of the loading portion (126) and intended to push a part to be defrosted (104) to deform said part (104). The movable portion (114) of the actuator (110) and the loading portion (126) of the intermediate element (124) are not connected to one another, such that the loading portion (126) of the intermediate element (124) cannot pull the movable portion (114) of the actuator (110) so as to move same away from the stationary portion (112).

摘要： An ultrasonic motor comprising a rotor (18) shaped at least partially spherically and two actuators (2, 2') each comprising an element made from a piezoelectric material in the shape of a plate comprising at least one contact edge (4, 4') in contact with the rotor (18), said actuators (2, 2') also comprising, on one of the faces of same, electrodes intended to bias piezoelectric materials in a bending mode and in a longitudinal mode. The contact edges (4, 4') are concave and are formed by an arc of a circle of which the radius substantially corresponds to the radius of the surface of the rotor (18), said arc of a circle extending angularly according to a predetermined angle such that the bending mode and the longitudinal mode in which the piezoelectric material is biased are at the same frequency.
