  • Patent number: 11925726
    Abstract: The present disclosure is related to a perfusable-type bio-dual proximal tubule cell construct and a producing method thereof capable of applying an in vitro artificial organ model configured to include a first bioink comprising a decellularized substance derived from a mammalian kidney tissue and human umbilical vascular endothelial cells (HUVECs) and a second bioink comprising the decellularized substance and renal proximal tubular epithelial cells (RPTECs), wherein the first bioink and the second bioink are coaxial and printed in tubular constructs having different inner diameters. According to the present disclosure, it is possible to use the renal proximal tubule-on-a-chip as a bioreactor capable of observing a biological drug reaction similar to a real drug by perfusing various drugs to the renal proximal tubule-on-a-chip.

  • Patent number: 5625221
    Abstract: A semiconductor package assembly includes recessed edge portions extending along at least one edge portion of the assembly and an upper surface of leads being exposed therefrom, a top recess portion disposed on a top surface of the assembly, and a bottom recess portion disposed on a bottom surface of the assembly. When the assemblies are used in fabricating a three-dimensional integrated circuit module, the recessed edge portions accommodates leads belonging to an upper semiconductor assembly to achieve electrical interconnection therebetween, the top recess portion and the bottom recess portion belonging to an upper semiconductor assembly form a space to accommodate a heat sink or a capacitor plate.

  • Patent number: 5229069
    Abstract: This invention reveals steel alloys which are particularly suitable for use in manufacturing reinforcing wires for rubber products, such as tires. The steel filaments made by this process have an outstanding combination of strength and ductility. Additionally, the steel alloys of this invention can be patented in a low cost process due to their having a very fast rate of isothermal transformation. This allows the steel in the steel wire being patented to transform from a face centered cubic microstructure to an essentially body centered cubic microstructure within a very short period. This invention more specifically discloses a steel alloy composition which is particularly suitable for use in manufacturing reinforcing wire for rubber products which consists essentially of (a) about 92.8 to about 99.18 weight percent iron, (b) about 0.4 to about 1.5 weight percent carbon, (c) about 0.05 to about 1 weight percent silicon, (d) about 0.05 to about 1.2 weight percent manganese, (e) about 0.01 to about 1.

  • Patent number: 5189897
    Abstract: A method and apparatus for drawing steel wire to produce high tensile strength, steel wire with increased torsional ductility. The wire is drawn through a plurality of standard dies (14) in a wire drawing machine (10). The cross section of the wire is reduced by a constant reduction of about 15% to about 18% at each of the standard dies (14) with the exception of the final two dies (18, 19). The wire is then reduced by about 10% to about 90% of the typical reduction at the next to last die (18) and the remainder of the reduction at the final die (19).

  • Patent number: 4545834
    Abstract: This invention reveals a steel wire element useful in the reinforcement of rubber articles in which the steel wire is provided with an adhesive coating comprising a ternary brass alloy containing about 55 percent to about 75 percent by weight copper, about 15 to about 45 percent by weight zinc, and about 0.1 to about 10 percent by weight iron. Preferably this ternary brass alloy will contain about 1 to 5 percent by weight iron. The ternary alloy may be formed by sequentially electroplating layers of copper, iron and zinc followed by heating to promote the diffusion of the copper, iron and zinc layers. The steel wire elements of this invention are useful in the reinforcement of vehicle tires, power transmission belts, conveyor belts, hoses, and the like.
