An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly. After fibrosis is complete, natural brain-induced contraction and relaxation of the ciliary muscle relaxes and stretches the fibrosed anterior remnant and increases and reduces vitreous pressure in the eye to effect vision accommodation by the remnant, the posterior capsule, and vitreous pressure.

Further, a radial width necessary to guide the bus wires is reduced, and an axial height of the motor including a sensor portion which detects a rotary position of the motor is reduced. Also, the bus wires are easily extended from the armature, and an amount of work required to connect the bus wires and the terminals is reduced. Furthermore, the connection terminal portion does not interfere with the bus wires when they are being guided.

An improved variable geometry diffuser (VGD) mechanism for use with a centrifugal compressor. This VGD mechanism extends substantially completely into the diffuser gap so that the VGD mechanism may be used more fully to control other operational functions. The VGD mechanism may be used to minimize compressor backspin and associated transient loads during compressor shut down by preventing a reverse flow of refrigerant gas through the diffuser gap during compressor shutdown, which is prevented because the diffuser gap is substantially blocked by the full extension of the diffuser ring. During start-up, transient surge and stall also can be effectively eliminated as gas flow through the diffuser gap can be impeded as load and impeller speed increase, thereby alleviating the problems caused by startup loads at low speeds. The VGD mechanism can be used for capacity control as well so as to achieve more effective turndown at low loads.

Each tooth of a stator core has circumferential projections at an inner tooth edge and circumferential notches at a base portion adjacent to a core back.

In addition, a plurality of the magnetic strips can be formed from a long and thin magnetic sheet. This increases the yield percentage of the magnetic strip and reduces a manpower of manufacturing the magnetic strip. Further, the notches make it easy to wind the magnetic strip into a cylindrical core.
