摘要： An optical beam transformation system includes a first and a second optical element, each of which has a non-reentrant surface. The system transforms a substantially non-uniform optical input beam (such as a Gaussian) to a substantially uniform output beam. The first and second optical elements are arranged in either a Keplerian or Galilean configuration. The aspheric surface of the second optical element is related to the aspheric surface of the first optical element by a ray-tracing function that maps substantially all of an input light beam that is incident on the first optical element to a collimated output light beam that is output from the second optical element. Preferably, the output light beam has a Fermi-Dirac intensity distribution, and the ray-tracing function maps the input light beam to the output beam out to the (1/e)6 intensity radius of the input light beam.

摘要： The present invention relates to an improved high speed rotary bone cutter comprising a drive shaft and a cutting head. The drive shaft has an elongated housing rotably mounted on the shaft. The housing has an enclosed fluid passageway around the shaft for the flow of cutting fluid. The passageway insulates the flowing fluid from the high rotational speed of the drive shaft.

摘要： A method of and structure for optical recording by energy-induced homogenization or fractionation is disclosed. When the method involves fractionation, a film is provided that contains a homogeneous mixture of a matrix material and an incident energy absorbing material. A spot on the film is treated with sufficient energy in the form of electric fields, radiation or heat, or combinations thereof to effect fractionation and/or homogenization of the film which will undergo further physical state transition only under treatment with additional energy. In a preferred embodiment, the fractionation is effected by laser radiation. The laser irradiated spot becomes inhomogeneous and can be detected by the resulting changes in its optical properties. When the method involves homogenization, a film is provided that contains a inhomogeneous mixture. The energy treated spot in this case becomes homogeneous without undergoing a phase transition between the amorphous and crystalline phases. Numerous combinations of fractionation and homogenization can result in the writing and erasing of information in a storage device.

摘要： A slider assembly for supporting a magnetic head a small uniform spacing above the surface of a magnetic recording medium comprising a slider body having a layer of superconducting material on the surface of the slider assembly which faces the surface of the magnetic recording medium. The slider assembly is maintained in a vacuum of a predetermined level or in a predetermined gas, and the slider assembly is cooled to a temperature below the critical temperature of the superconductor material so that the slider assembly and the magnetic transducer are levitated to a small uniform spacing above the surface of the magnetic recording medium due to magnetic forces between the magnetized magnetic recording medium and the layer of superconducting material.
