Abstract: A rotor assembly for a permanent magnet motor includes a rotor stack of laminated ferromagnetic layers and partial end plates at opposite axial ends of the rotor stack wherein each axial end of the rotor bears two partial end plates, each of which covers a partial circle and does not axially overlap with the other one of the partial end plates at the same axial end. The two partial end plates of each axial end are formed by a first axial end plate shaped as a first partial ring disc and a second partial end plate shaped as a second partial ring disc that are made of stamped metal and that are of different mass.

Abstract: A method for processing product wafers using carrier substrates is disclosed. The method includes a step of bonding a first carrier wafer to a first product wafer using a first temporary adhesion layer between a first carrier wafer surface and a first product wafer first surface. Another step includes bonding a second carrier wafer to a second product wafer using a second temporary adhesion layer between a second carrier wafer surface and a second product wafer surface. Another step includes bonding the first product wafer to the second product wafer using a permanent bond between a first product wafer second surface and a second product wafer first surface. In exemplary embodiments, at least one processing step is performed on the first product wafer after the first temporary carrier wafer is bonded to the first product wafer before the second product wafer is permanently bonded to the first product wafer.

Abstract: Pilot switch circuitry grounds a hot node (an injection node) of a microelectromechanical system (MEMS) switch to reduce or eliminate arcing between a cantilever contact and a terminal contact when the MEMS switch is opened or closed. The pilot switch circuitry grounds the hot node prior to, during, and after the cantilever contact and terminal contact of the MEMS come into contact with one another (when the MEMS switch is closed). Additionally, the pilot switch circuitry grounds the hot node prior to, during, and after the cantilever contact and terminal contact of the MEMS disengage from one another (when the MEMS switch is opened).

In one exemplary embodiment, the MEMS device (100) comprises a substrate (106) having a surface, an electrode (128) having a first portion coupled to the substrate surface, and a second portion movably suspended above the substrate surface, and a stress-release mechanism (204) disposed on the electrode second portion, the stress-release mechanism (204) including a first slot (208) integrally formed in the electrode. In another exemplary embodiment, the substrate (106) includes an anchor (134, 136) and the stress-release mechanism 222 is formed adjacent the anchor (134, 136).

Abstract: An electromagnetic clutch assembly of the leaf spring type has leaf springs the inner ends of which are fixed to a drive plate by conventional rivets, and the outer ends of which are fixed to the armature plate by special rivets having enlarged diameter shanks that extend through clearance holes in overlaying portions of the drive plate. Rubber damper rings are trapped beneath an enlarged head of the rivet, against the outer surface of the driver plate, without intruding into the radial clearance. The clearance holes allow the rubber rings to compress freely as the leaf springs flex when the clutch is activated. During operation, the transmission of torsional vibrations back through the drive plate and springs to the armature plate is dampened by the compressed rubber rings.

Abstract: A micro-electromechanical (MEM) device has a folded tether spring in which each fold of the spring is surrounded by a rigidly fixed inner structure and outer structure. The fixed inner structure increases restoring force of the spring. The rigidly fixed inner and outer structures each have a major surface that include a plurality of notches of fixed width relative to a distance between the major surface and the spring. Additionally in one form extensions from the major surface of the rigidly fixed inner and outer structures are provided at distal ends thereof to make initial contact with the spring. The notches of the MEM device both reduce surface area contact with the spring and wick moisture away from the spring to minimize stiction.

Abstract: The subject invention improves the electrical connection in a clutch assembly for engaging a compressor in a vehicle air conditioning system. In accordance with the subject invention, a tab extends from the mounting plate and the second end of the ground lead is frictionally retained between the tab and the core winding housing. This is accomplished by turning a tab out of the plane of a mounting plate, placing the second end of the ground lead under the tab and bending the tab downwardly to clamp the second end of the ground lead between the tab and the core winding housing to frictionally retain the second end of the ground lead between the tab and the core winding housing.
