Direct tympanic drive via a floating filament assembly
InactiveUS6940989B1Efficient couplingFrictionCompletely in canal hearing aidsEar treatmentAir coreEngineering
A canal hearing device has a subminiature filament assembly which vibrates and directly drives the tympanic membrane (eardrum) and imparts audible mechanical vibrations thereto. The filament assembly is partially supported by the tympanic membrane via capillary adhesion thereto and is dynamically coupled to a stationary vibration force element position at a distance from the tympanic membrane within the ear canal. The elongated filament assembly is freely movable within an operable range and is essentially floating with respect to the vibration force element. In a preferred embodiment, the vibrational filament assembly comprises a magnetic section which is insertable into the air-core of an electromagnetic coil. The filament assembly is coupled to the tympanic membrane via an articulated tympanic contact coupler.

In-situ performance prediction of pad conditioning disk by closed loop torque monitoring
ActiveUS20100035525A1Convenient lifeFrictionEdge grinding machinesGrinding drivesOperant conditioningClosed loop
Polishing pads used in CMP machines are consumable components that are typically replaced after a specific number of wafers have been processed. The life of a polishing pad is optimized by controlling the rate of material removal from the polishing pad by the conditioning disk. The conditioning disk removes enough material so the polishing surface can properly process the wafers but does not remove any excess material. Preventing excess material removal extends the life of the polishing pad. During CMP processing, the controller receives data concerning the torque applied to the conditioning disk and the torque applied to the arm to sweep the conditioning disk across the polishing pad. Based upon the detected operating conditions, the system can predict the rate of material removal and adjust the forces applied to the conditioning disk so that the life of the polishing pad is optimized.

A thrust bearing device is constituted by a turbine-side thrust collar and a compressor-side thrust collar that are fixed to a rotary shaft; and a thrust bearing that is arranged between the thrust collars. The thrust bearing is provided with an oil passage that supplies lubricating oil r to sliding-contact surfaces formed between the thrust bearing and the thrust collars. The outsides of the thrust collars in a radial direction incline toward the thrust bearing side. A gap c between the sliding-contact surfaces is narrowed as the gap goes outward in the radial direction, and establishes a basic region gap (c1)>an outer peripheral end gap (c2). The lubricating oil outflow resistance of a radial outer region of the gap c becomes larger than that of a radial inner region. Therefore, the lubricating oil r can be kept from flowing out from a radial outer outlet.
