  • Patent number: 5280857
    Abstract: A comminuting device for breaking-up charge bodies of frangible material to free their value content and to reduce it to a desired size employs an upright enclosure into which charge bodies are fed so as to minimize in-air flow and to provide a steady stream of the bodies into the upper end of a centrally positioned downflow feed duct from which a series of horizontally, radially outwardly extending and vertically spaced-apart discs of a rotating assembly are suspended to define a central chamber selection passageway that is open at its upper end to the lower end of the duct, and at its bottom end through a grating to a motor drive compartment into which a fluid is introduced under positive pressure.

  • Patent number: 5226056
    Abstract: In a method for plasma ashing a resist film coated on a substrate, the temperature of the substrate is controlled initially at temperatures below that at which explosion of the resist film occurs until a surface portion of a resist film has been removed. Thereafter, the substrate temperature is increased to remove the remaining portions of the resist film. An apparatus for conducting the method includes a plurality of supports, which may be movably disposed within a vacuum treatment chamber for moving the substrate away from a source of heat and for moving the substrate into contact with the heating source.

  • Patent number: 5193095
    Abstract: A multi-mode Raman laser system wherein Raman conversion is performed by injecting exciting laser beam from transversely excited atmospheric pressure CO.sub.2 laser system into a Raman cell. Unstable resonator type oscillator is used as transversely excited atmospheric pressure CO.sub.2 laser system; and multi-mode Raman cell is used as the Raman cell. The quantity required for an excited CO.sub.2 laser system can thus be extensively reduced. Also, it is possible to reduce the input electric required for obtaining the same energy of 16 .mu.m light which is scattered light, because saturated conversion of excited light, can be achieved by multi-mode Raman cell, and system efficiency can be increased.
