  • Patent number: 8007910
    Abstract: A multilayer coating (MLC) is composed of two chemically different layered nanocrystalline materials, nanodiamond (nanoD) and nano-cubic boron nitride (nono-cBN). The structure of the MLC and fabrication sequence of layered structure are disclosed. The base layer is preferably nanoD and is the first deposited layer serving as an accommodation layer on a pretreated substrate. It can be designed with a larger thickness whereas subsequent alternate nano-cBN and nanoD layers are typically prepared with a thickness of 2 to 100 nm. The thickness of these layers can be engineered for a specific use. The deposition of the nanoD layer, by either cold or thermal plasma CVD, is preceded by diamond nucleation on a pretreated and/or precoated substrate, which has the capacity to accommodate the MLC and provides excellent adhesion.

  • Patent number: 7645513
    Abstract: Cubic boron nitride/diamond (cBND) composite films with excellent adherence to various substrates and their fabrication method are disclosed. The cBND composite confining cBN can be prepared without any amorphous/turbostratic BN (aBN/tBN) incubation layers. The cBND composite is established on the compatibility of structural and physical properties of two superior materials: cBN on top and diamond beneath. The underlying diamond is adapted to the substrate of choice using a variety of methods which may include prescratching the substrates, bias enhanced nucleation, etching for depleting undesirable chemical elements, construction of buffer layers and gradient buffer layers for the isolation of undesirable chemical elements or/and adaptation of physical properties. The diamond nuclei are preferably formed either by bias-enhanced nucleation or by pre-scratching the substrate prior to nucleation.

  • Patent number: 7504890
    Abstract: A data-directed frequency-and-phase lock loop for an offset-QAM modulated signal comprises a first multiplier that multiplies the signal by the output of a VCO. The output of the first multiplier is phase-shifted by a second multiplier, then convolved by a third multiplier. The output of the third multiplier is split, with each portion being passed through a frequency-shift multiplier and a frequency-and-phase lock loop. The output of the two frequency-and-phase lock loops is summed and returned to the VCO to complete the feedback loop.
