  • Patent number: 11619249
    Abstract: A vehicle driveline component with a housing, a tube and a plurality of slugs. The housing has a tube mount with a body and a plurality of slug bores. The body defines a tube bore that extends along an axis. The slug bores are spaced circumferentially apart about and are formed through the body. Each of the slug bores intersects the tube bore. The tube is received in the tube bore. Each of the slugs is received into an associated one of the slug bores and is welded to the tube. Each of the slugs engages an inside surface of one of the slug bores to inhibit movement of the tube relative to the tube mount. The body has a wall thickness and each of the slugs engages the inside surface of one of the slug bores over a distance that is less than the wall thickness.

  • Publication number: 20230023186
    Abstract: A semiconductor device includes a substrate, a 2-D material layer, source/drain contacts, and a gate electrode. The 2-D material layer is over the substrate, the 2-D material layer includes source/drain regions and a channel region between the source/drain regions, in which the 2-D material layer is made of a transition metal dichalcogenide (TMD). The source/drain contacts are in contact with source/drain regions of the 2-D material layer, in which a binding energy of transition metal atoms at the channel region of the 2-D material layer is different from a binding energy of the transition metal atoms at the source/drain regions of the 2-D material layer. The gate electrode is over the substrate.

  • Publication number: 20210308806
    Abstract: A weldment includes a first component, a second component, and a weld joint coupling the first and second components together. The weld joint forms a heat affected zone in the first component and creates residual tensile stress in the first component. The first and second components cooperate to define a pocket configured to position a highest magnitude of the residual tensile stress in the first component in a location that is outside of the heat affected zone of the first component.

  • Patent number: 9156110
    Abstract: A weldment in which a first component defines a bore, a second component is received in the bore and a weld is employed to couple the second component to the first component. The first component has an isolation pocket formed about the bore such that an annular projection having an annular collar portion is formed. The isolation pocket is sized and positioned relative to the weld such that the annular collar portion is deflected about the base into a position that is radially inwardly from a position of the annular collar portion prior to the formation of the weld such that the isolation pocket controls axial shrinkage associated with the formation and cooling of the weld.

  • Publication number: 20150203688
    Abstract: The present invention provides a light curable colored coating, comprising a photoinitiator, a UV resin and a UV photosensitive phosphor, wherein the light curable colored coating is formed by mixing and then separating the photoinitiator, the UV resin and the UV photosensitive phosphor, wherein the mixture is applied to a substrate thereafter, and thus the curing time of the light curable colored coating is largely shortened.
