  • Patent number: 12264352
    Abstract: A method for enhancing extracellular vesicle production is described. A peptide that induces polymer formation is incubated with a cell culture which results in enhanced EV production. The peptide penetrates the cells and subsequently polymerizes upon exposure to enzymes (e.g. phosphatase) within the cell. The cells that contain the newly formed polymers have an increased production of EVs. These EVs can be harvested using centrifugation techniques.

  • Publication number: 20250084497
    Abstract: Disclosed is a method for producing a plated black heart malleable cast iron member including a black heart malleable cast iron member and a plating layer formed on a surface of the black heart malleable cast iron member, the method including the steps of: performing graphitization in a non-oxidizing and decarburizing atmosphere; performing a particle projection treatment on a surface of the black heart malleable cast iron member obtained after the graphitization such that silicon oxide remains on the surface; immersing the black heart malleable cast iron member obtained after the particle projection treatment in a flux for 3.0 minutes or more; and performing hot-dip plating on the black heart malleable cast iron member obtained after the immersion in the flux.

  • Patent number: 11739401
    Abstract: Provided is a black heart malleable cast iron and a method for manufacturing the same which can significantly shorten the time required for graphitization, as compared with the prior art. The black heart malleable cast iron includes a matrix of ferrite and lump graphite included in the matrix, and includes at least one selected from the group consisting of (i) 0.0050% by mass or more and 0.15% by mass or less of bismuth and 0.020% by mass or more of manganese, and (ii) 0.0050% by mass or more and 1.0% by mass or less of aluminum and 0.0050% by mass or more of nitrogen. In addition, the grain size of the matrix is 8.0 or more and 10.0 or less in terms of grain size number, numerically determined by comparison between a metallographic photograph of the matrix and a standard grain size chart.

  • Patent number: 11325112
    Abstract: Nanocages are formed by etching nanocubes. The nanocubes are added to an aqueous system having an amphiphilic lipid dissolved in an organic solvent (e.g. a hydrophobic alcohol) to form reverse micelles. As the water evaporates the micelles shrink as etching of the flat surface of the nanocubes occurs. In this fashion hollow nanocages are produced. In one embodiment, the nanocage is covalently attached to a polymer shell (e.g. a dextran shell).

  • Patent number: 11065664
    Abstract: A machining surface of a die are provided with a pair of inclined surfaces facing each other across a gap and a flat surface interposed therebetween. Each inclined surface includes an inner end portion on a side near the flat surface and an outer end portion on a side farther away from the flat surface. The molding method includes a mounting step of mounting the metal sheet on the die to span both inclined surfaces, and a pressing step of forming a reduced-thickness portion by pressing the metal sheet between the punch and the inclined surfaces of the die. The pressing step includes setting a bottom dead center of the punch to maintain a gap formed between the inner end portion and a surface of the metal sheet facing the inner end portion.

  • Patent number: 10256869
    Abstract: This technology relates to a communication apparatus and a communication method adapted to improve the deterioration of communication performance due to variations in parts, for example. A test signal generating section generates a predetermined test signal. A detecting section detects, given a received test signal obtained by a transmitting and receiving section upon receipt of the test signal, an influence parameter affecting the intensity of an active load modulation signal that combines a transmission carrier with a synchronizing signal synchronized with a received signal obtained upon receipt of the transmission carrier. A controlling section controls the intensity of the active load modulation signal in accordance with the influence parameter. This technology applies to cases where short-range wireless communication is performed using magnetic fields.
