  • Patent number: 10001393
    Abstract: A metal mold includes a restraining part that is fitted in a recess provided at a part of surfaces of at least two resin parts that serves as an outer surface of a resin hollow body. A linear space is filled with high-pressure resin fluid injected at a predetermined injection pressure. The resin parts are joined together. The mold receives injection pressure of resin fluid, with which the space is filled, through the resin parts, and applies pressing force, which pushes back the resin parts toward the space, to the resin parts as reaction force against injection pressure. Stress is produced on a hollow wall surface in a direction in which the wall surface projects into a hollow portion due to injection pressure. The restraining part applies pressing force to the resin parts in a direction opposite from the stress projecting the wall surface into the hollow portion.

  • Patent number: 10001418
    Abstract: Embodiments generally relate to device and methods for detecting force. A force sensor may include a sense die, a substrate, one or more sense elements supported by the sense die, one or more electrical contacts located on the sense die and electrically coupled to electrical traces on the substrate, and an actuation element configured to transmit a force to the sense die. The width of the actuation element may be less than the distance between the one or more electrical contacts. In some embodiments, the actuation element may include a thin wedge/plate configured to interact with the sense die at a contact point. The thin wedge/plate may allow use of a smaller sense die and/or may allow closer placement of the one or more sense elements to the contact point and/or may prevent accidental contact with the one or more electrical contacts which may lead to a short circuit.

  • Patent number: 9995641
    Abstract: Apparatus and associated methods relate to a force sensor having flip-chip mounted force-sensing die having a force-sensing element fabricated on an unflipped top surface and an unflipped back surface being thinned so as to create a flexible diaphragm responsive to an externally applied force, wherein, when the force-sensing die is flipped and mounted, a predetermined space remains between the top surface of the force-sensing die and the mounting substrate it faces, the substrate presenting a deflection limitation for the deformation of the flexible membrane during a force event. In an illustrative embodiment, the force sensor may have a mechanical stop to precisely establish a predetermined deflection limitation. In some embodiments, the predetermined deflection limitation may advantageously limit the deflection of the flexible membrane so as not to deflect beyond a breaking point.

  • Patent number: 9983111
    Abstract: A low-profile shear-sensing unit includes a floating plate surrounded by a frame and a displacement sensor that measures in-plane movement of the floating plate. Covered with a surface sample, the floating plate is displaced by the friction drag (i.e., shear) on the surface caused by the flow of fluid and the in-plane displacement is measured by the displacement sensor. The shear force on the sample surface is then obtained by multiplying the measured displacement and the spring constant of the flexure beams, which suspend the floating plate. The floating plate and the flexure beams are formed out of one plate or substrate to achieve monolithic construction with a beam geometry that leads to a high-resolution measurement.
