Patents by Inventor Charles S. Guenzer

Charles S. Guenzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040000478
    Abstract: A hollow cathode sputtering target and associated magnetron. The target includes a tubular sidewall and a circular roof forming a cylindrical vault arranged about an axis. The sidewall is surrounded by a first set of magnets of a first magnetic polarity along the axis. A second set of magnets, disposed in back of the roof, and asymmetric and rotatable about the axis, includes an outer pole preferably of the first magnetic polarity surrounding an inner pole of the opposed magnetic polarity and of lesser total magnetic intensity. Optionally, the roof and sidewall are separate members having individual power supplies. Further optionally, the first set of magnets are asymmetric and rotatable with the second set of magnets about the axis.

  • Patent number: 5556463
    Abstract: A method of forming a crystallographically oriented silicon layer over a glassy layer of, for example, SiO.sub.2. A templating layer of a layered perovskite, preferably Bi.sub.4 Ti.sub.3 O.sub.12, is deposited on the glassy layer under conditions favoring its crystallographic growth with its long c-axis perpendicular to the film. The silicon is then grown over the templating layer under conditions usually favoring monocrystalline growth. Thereby, it grows crystallographically aligned with the underlaying templating layer.

  • Patent number: 4529884
    Abstract: A spectral dosimeter for detecting both the fluence and the energy spectrum or ionization density spectrum of high energy radiation comprising multiple MOS capacitors on a single semiconducting integrated circuit chip which collect ionization charge generated by high energy particles passing in the vicinity of the individual capacitors. The capacitors are individually read by comparison with reference capacitors. The capacitors are fabricated or operated such that varying amounts of collected charge will cause the capacitors to be read as having collected a threshold amount of charge.

  • Patent number: 4490016
    Abstract: A polarimetric image recorder which records only the net polarization of the viewed scene. An optical lens system projects the light originating from the viewed scene onto a thin layer of an alkali halide crystal containing anisotropic color centers. Polarized light reorients the color centers and creates a net polarization in the layer. The net polarization of the layer is read by such means as shining polarized light through the layer and then through a polarizer set perpendicularly to the polarization of the light source. Whatever light is viewed through the reader represents a net polarization in the scene.
