Abstract: In accordance with a first aspect of the present disclosure, an antenna unit is provided, comprising: an integrated circuit package containing an integrated circuit die and an antenna structure coupled to the integrated circuit die; a dielectric layer separated from the integrated circuit package, wherein the dielectric layer is placed at a predefined distance above an upper surface of the integrated circuit package. In accordance with a second aspect of the present disclosure, a corresponding method of producing an antenna unit is conceived.

Abstract: The apparatus includes a frame supporting two fixtures, of which at least one is movable, and which have respective crescents adapted to be brought together to form a circular profile engageable with the big end of a connecting rod and separable by an opening device for fracturing the big end of the connecting rod. The opening device comprises a pusher device which has a sloping surface and is slidably supported with respect to one of the crescents to abut against the other crescent, and a driving member, which is slidable transversely to the pusher device under control of driving elements, and has a sloping surface that is adapted to cooperate with a camming action with the sloping surface of the pusher device.

Abstract: A frame (10) carries two fixtures (16, 20), of which at least one (20) is movable, and which have respective crescents (18, 22) adapted to be brought together to form a circular profile engageable with the big end of a connecting rod and separable by opening means for fracturing the big end of the connecting rod.

Abstract: A machining head (36) is drivable along a vertical axis and two horizontal axes with respect to a workpiece held on a workpiece-holding device, and has, at progressively lower levels along said vertical axis, one or two high-speed spindles (44), one or two low-speed spindles (46) and one or two feed-out spindles (48), all arranged at right angles to said vertical axis and driven by one or more motors (42) mounted on the head. The machining head can bring the high-speed spindles to cooperate with a tool-changing magazine (52). The workpiece-holding device (54; 154) is adapted to carry two sets of workpieces on respective supports (56, 58; 170), and to shift said supports in succession between a working position near the head and a tool-changing position remote from the head.

Abstract: A working head for numeric-control machine tools is adapted to be moved along two or three axes relative to one or two parts mounted on respective worktables which can rotate about respective parallel axes. According to the present invention, the head supports one or preferably two tool-supporting spindles which are pivoted about a common axis which is transverse to the axes of the spindles under the actuation of motor means which are rigidly coupled to the head and are controlled by a numeric control unit.

Abstract: According to the invention, parting of the cap of the connecting rod is achieved by engaging the eye of the big end of the connecting rod with two semicylindrical fixtures, respectively a fixed fixture and a movable fixture, which are actuated by a hydraulic actuator which is interposed between them and is adapted to expand the fixtures in a diametrical direction against the inner surface of the eye of the big end of the connecting rod, subjecting the piston of the actuator to the action of a hydraulic fluid fed into the respective actuation cylinder at an optional pre-loading pressure that is in any case lower than the pressure required to reach the yield point of the material of the connecting rod, and producing an instantaneous peak in the pressure of the fluid fed to the hydraulic actuator by means of an auxiliary piston that is subjected to the momentary action of a striking mass.
