Patent number: 11940347Abstract: 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.Type: GrantFiled: October 22, 2021Date of Patent: March 26, 2024Assignees: DENSO CORPORATION, NAGANO KEIKI CO., LTD.Inventors: Hiroshi Kodama, Naoki Yoshida, Kaori Miyashita, Eiji Takeda, Nobuaki Yamada, Yoshihiro Tomomatsu, Yasushi Yanagisawa, Yusuke Midorikawa, Shirou Kamanaru, Kenichi Yokoyama, Inao Toyoda, Hisayuki Takeuchi, Naohisa Niimi, Masao Takahashi, Yasutake Ura, Kouji Asano, Yukihiro Kamada

Patent number: 10081480Abstract: 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.Type: GrantFiled: March 12, 2015Date of Patent: September 25, 2018Assignee: MITSUBISHI GAS CHEMICAL COMPANY, INC.Inventors: Kenichi Niimi, Kiyonori Michiba, Takashi Kubo, Kazuyuki Minato, Yoshiki Itou, Takayoshi Itoh, Jungo Taguchi, Akihiro Masuda, Tatsuo Iwai
