  • Patent number: 11940347
    Abstract: A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

  • Patent number: 10081480
    Abstract: An oxygen-absorbing container includes a container body having a multilayer structure constituted by an innermost layer, an outermost layer and an intermediate layer therebetween, the container body having an opening part on an upper part thereof; and a sealing member bonded to an upper end surface of the opening part of the container body to seal an opening of the opening part. The innermost layer and the intermediate layer are bent outward at an upper end of the opening part and form a flat part and a surface of the flat part forms the upper end surface of the opening part. When the sealing member is unsealed, part of the innermost layer on the upper end surface of the opening part is configured to be peeled off so as to leave an unsealed mark.
