  • Patent number: 12109601
    Abstract: A method for manufacturing a press-formed product suppresses occurrence of a forming defect such as a crack in a starting material during press forming, and also suppresses occurrence of problems when transferring a starting material during press forming. A manufacturing intermediate is formed by forming, in a flat-sheet shaped blank sheet, a planned outline portion including an undulating shape which is used for forming an outline of an outer circumferential portion of a press-formed product. The flat shape of the blank sheet is maintained in a region from the planned outline portion toward the center of the manufacturing intermediate, or an intermediate stretch-formed portion having a predetermined intermediate forming height is formed in the manufacturing intermediate in the region. A through-hole is formed by piercing a flat portion at which the flat shape is maintained or a stretch-formed-side top portion of the intermediate stretch-formed portion.

  • Publication number: 20240167901
    Abstract: A pressure-sensing element includes a membrane, a substrate, a guard, and a base. The membrane includes a diaphragm. The substrate is opposite to the membrane in a thickness direction. The guard is between the membrane and the substrate and is bonded to the membrane and the substrate. The guard has a closed shape. The base is in an enclosed space defined by the membrane, the substrate, and the guard. The base is bonded to the membrane and is separated from the substrate and the guard. The base includes a first electrode opposed to the diaphragm with a pressure reference chamber between the first electrode and the diaphragm to provide electrostatic capacitance. The base except for the first electrode is bonded to the membrane. A trench extends in the thickness direction entirely through the membrane and partially through the guard.
