Dynamic balancing reduces quadrature bias in microfabricated vibrating instruments such as tuning fork gyros so that a purity of motion is achieved in the absence of any angular rate input. Balancing is achieved by ablating ( ) or depositing ( ) onto support structure ( ) for a tuning fork gyroscope rather than the proof mass ( ) itself by melting and moving material on a tuning fork beam ( ). Such adjusting is advantageously done during actual operation of the gyro by laser beam application through an encapsulating transparent cover which can be either part of the chip die or an external package.

A hybrid wafer gyroscope includes a combination of micro-machined components and traditional electromechanical components to form a miniature gyroscope having a high degree of stability. The gyroscope includes a rotor, gimbal, flexures, and stop cutouts micro-machined out of one or more layers of silicon, forming a unitary, planar, and disk-shaped rotor subassembly, which spins about a drive shaft.

Model and method of treating inflammatory diseases. Traditional treatments for such diseases include administering to the patient toxic anti-inflammatory drugs. Following stabilization of the symptoms, the drug doses are tapered down to minimize side effects, as a result of which inflammation remains high and the disease is rarely cured. A chemistry-based disease model concludes that irrespective of the role that inflammation plays in the disease, inflammation reduction will impede disease initiation and progression. Managing and controlling inflammatory diseases requires reducing inflammation to acceptable normal values. Non-toxic ways such as anti-inflammatory diets and regular exercise allow such reduction in inflammation to normal values, thereby slowing down or arresting disease progression and allowing reduction in the required anti-inflammatory drug maintenance dose.

A highly aligned rare-earth transition metal alloy magnet material such as samarium-cobalt (SmCo. sub. 5). The high degree of alignment is evidenced by an isolated X-ray diffraction pattern peak for Cu. sub. k. alpha. radiation at a interplane "d" spacing of 2. 0 A. degree. and is produced by very high temperature deposition of the material on a hot surface. The surface temperature is maintained well above 800 degrees centigrade and most preferably is initially set at approximately 1020 degrees centigrade or higher at which temperature the isolated diffraction pattern peak dominates. A higher temperature typically occurs during deposition. Deposition of the material on the surface typically takes place by application of the material as a fine, homogeneously sized powder to the plasma flame of a plasma torch. The surface may be preheated by the application of the plasma flame to the surface without the application of the powdered material. A feedback controlled auxiliary heat source may also be used to facilitate maintaining the temperature of the surface at the very high temperature level.

Apparatus and method for forming radial orientation rare earth-transition metal magnets in continuous arc rings by hot isostatic pressing. A method includes the steps of compacting rare earth-transition metal powders having a particle size up to 40 microns into radially oriented rings in a mold provided with a radially aligning field, stacking a plurality of compacted radially oriented rings within an annular cavity within a sealed, evacuated cannister to form a cylinder of a predetermined height, subjecting the cannister to temperatures in the range of 900. degree. to 1150. degree. C. under a gas pressure of 15 kpsi to densify the compacts, and cooling the cannister and the compacts to room temperature. An apparatus for performing the above-described method, includes a mold for forming green compacts having a central iron core or mandrel, an outer housing forming an annular space between it and the iron mandrel, plungers for compacting into a ring rare earth-transition metal powder within the annular space, and means for forming a radially oriented magnetic field. The magnetic field forming means includes a pair of electromagnetic coils with bucking fields disposed on opposite axial ends of the annular space.

Method and apparatus for the formation of a molded article from powders and powder compacts of a material by pressure compaction of the powders under the influence of a thermally driven differential volume expansion of first and second elements constraining the powders. The volume expansion achieves a trippling of the compaction effect.
