摘要： A variable reluctance rotation sensor comprising a flux member having a ferromagnetic pole piece formed of a cylindrical center portion interposed between a first and second end portion. Each of the end portions have a respective surface which contains elongated teeth, similarly separated by slots as teeth on the periphery of a toothed wheel. The cylindrical center portion is positioned with respect to the toothed wheel such that the toothed surfaces of the first and second end portions are positioned adjacent the periphery of the toothed wheel comprising the teeth and slots, the magnetic flux member and toothed wheel defining an air gap. The sensor further comprises permanent magnets which establish main flux loops traversing the air gap, and leakage flux loops linking an electrical coil wound about the cylindrical center portion. As the toothed wheel is rotated, the magnitude of the main flux loops vary in relation to the varying air gap. The leakage flux loops, in turn, vary in relation to the varying main flux loops, the varying leakage flux loops being linked to the electrical coil and resulting in a sinusoidal output voltage signal proportional to the varying leakage flux loops. Each cycle of the output signal corresponds to a predetermined incremental angular rotation of the toothed wheel.

摘要： A variable reluctance rotation sensor comprises a rotatable magnetic toothed wheel adjacent a fixed magnetic pickup assembly. The pickup assembly comprises a pair of permanent magnets, each with a similar pole adjacent the wheel and separated circumferentially by the arc between a tooth and a non-adjacent slot. A magnetic flux member with a coil joins the other poles of the magnets in series opposed relationship and extends in close proximity to the tooth wheel to establish separate flux loops for each magnet distributed along the coil. The flux loops are spatially determined by the teeth and slots between the permanent magnets, so that they fluctuate circumferentially and generate an electrical signal in the coil with wheel rotation by variation of the flux linkages to individual turns of the coil. The sensor thus uses spatial flux changes to produce a rotation signal at very low rotational speeds with a larger air gap than that of conventional sensors.

摘要： A means is provided for improving the magnetic permeability of a magnetic circuit within a variable reluctance sensor having off-set, permanent magnets by appropriately annealing the magnetic flux member. The annealing process includes heating the machined magnetic flux member in a vacuum to a temperature and for a duration sufficient to austenitize the magnetic steel so that full carbide solution is obtained, for example about 1300.degree. F. to about 1550.degree. F. for a duration of about 15 to 30 minutes. The magnetic flux member is then appropriately cooled in the vacuum so as to prevent the formation of martensite. The magnetic circuit, incorporating the annealed magnetic flux member, exhibited improved magnetic permeability, and the sensor signal was increased by as much as about 60 percent during operation. The method of this invention enhances the overall effectiveness of the sensor, particularly when sensing low rotational speeds such as when employed within automotive anti-lock braking or traction control systems.

摘要： An integral variable reluctance sensor and bearing grease seal assembly (sensor assembly) has at least one magnet and an annular wire coil secured at the interior of a housing which seals an annular space between a dynamic inner race and a static outer race. The sensor assembly is characterized by a relatively large flux change and resulting large peak to peak periodic output due to exploitation of the outer race and housing as high permeance flux paths in the sensor magnetic circuit and an additive arrangement of plural magnets. Sensor output signal strength is variable in step with the number of magnets and output variations due to air gap variations are minimized by symmetrical distribution of the same. The sensor assembly is further characterized by a single dynamic seal and no moving parts.

摘要： A variable reluctance rotation sensor comprises a rotatable toothed wheel and a magnetic pickup assembly comprising a pair of permanent magnets each having a pair of poles with an opposite one of said poles adjacent the toothed wheel. The permanent magnets are separated from each other by an arc equal to the arc between two of the teeth and joined by a magnetic flux member with a multi-turn electrical coil wound thereon. The flux member establishes a common main flux loop through the first and second permament magnets but also extends close to the toothed wheel to further establish additional flux loops separately through each of the permanent magnets. Passage of alternating teeth and slots as the wheel rotates produces a spatial fluctuation in the additional flux loops between the magnets to vary the flux linkages with individual coil turns and increase the electrical signal in the coil over the signal level that would be produced by variations in air gap of the common flux loop alone. The sensor produces a rotational speed signal at very low rotational speeds of greater amplitude and/or with a larger minimum air gap than that of conventional variable reluctance sensors.

摘要： A liquid immersion exposure apparatus includes a projection optical system (PL) which projects an image of a pattern onto a substrate (W) and a unit (5) which supplies a liquid (7) between an optical element (4) at the end of the projection optical system (PL) and the substrate (W). A corrosion-resistant film composed of an oxide is formed on the surface of the optical element (4) to prevent corrosion by the liquid (7). Consequently, a desired performance of the projection optical system can be secured for a long time even where a full field exposure in the step-and-repeat manner or a scanning exposure in the step-and-scan manner is performed in a liquid-immersion state.

摘要： A mirror for, e.g, an excimer laser is disclosed having high reflectance for a broad band of wavelengths in the ultraviolet range exhibiting excellent adhesion and "laser durability." The mirror comprises a substrate formed from glass or a glass-like material, a dielectric film, and a metallic film, such as aluminum foil, positioned between the dielectric film and the substrate. The dielectric film includes alternating layers of high- and low-refractive index material. These alternating layers reduce the amount of incident light reaching the metallic film so that any damage to the metallic film caused by light is reduced, thereby increasing the laser durability of the mirror. The laser durability is also increased because the durability of the laminated dielectric film is generally superior to that of the metallic film used in prior-art metallic reflector mirrors.
