  • Publication number: 20240084244
    Abstract: The present disclosure concerns recombinant yeast host cells having a first genetic modification to express a heterologous polypeptide or to over-express a native polypeptide. The recombinant yeast host cells also have a second genetic modification to at least partially mitigate the reduction in growth rate resulting from the expression of the heterologous polypeptide or the over-expression of the native polypeptide. The second genetic modification can be, for example, to favor the secretion of the heterologous or native polypeptide.

  • Patent number: 5939133
    Abstract: A slider of the type for use with a rotatable magnetic disk is disclosed. The slider has two ends and a bottom surface which includes an air bearing surface. An adhesive layer and continuous coating of carbon is located on the air bearing surface. A method of sputter depositing this continuous layer of carbon upon the air bearing surface of the slider is also provided. The continuous layer of carbon is crown-shaped and deposited using the sputtering technique. The carbon is directed from a source at the air bearing surface of a slider. A mask is placed between the source and slider so that the carbon is deposited in a crown shape. When the slider is viewed from front to rear the maximum depth of the coating is less than about 6 to 10 nm, while at the ends of the slider the coating depth is near 0 nm. The resistivity of the protective carbon layer is controlled for the additional benefit of protection from damages by electrostatic discharge.

  • Patent number: 4764834
    Abstract: A thin film transducer having a substrate, a first and second pole piece formed of a selected magnetic material and terminating in a gap, a coil positioned between the first and second pole pieces and a magnetically conductive layer formed of a material having selected chemical, magnetic and physical properties and having a known magnetic saturation flux density and being positioned contiguous at least one of the first pole piece and second pole piece and rearward of the edges forming the gap to conduct magnetic flux in parallel to the pole pieces and to increase and concentrate the magnetic flux density at the edges of the first and second pole piece defining the gap is shown.
