  • Publication number: 20240196612
    Abstract: A three-dimensional memory device includes alternating stacks of insulating strips and electrically conductive strips, backside trenches located between neighboring pairs of alternating stacks, memory openings vertically extending through the alternating stacks, and memory opening fill structures located within the memory openings. In some embodiments, dielectric etch stop structures may be located within or outside the backside trenches such that each of the dielectric etch stop structures includes a respective pair of dielectric sidewalls that are located within a pair of lengthwise sidewalls of the respective one of the backside trenches. In some other embodiments, a dielectric isolation structure can laterally contact each of the insulating strips within the alternating stacks. Laterally insulated contact via structures can be provided to provide electrical contact to a respective one of the electrically conductive strips.

  • Patent number: 11951926
    Abstract: A seating state detection device includes an acquisition unit configured to acquire a detection signal group in a predetermined period that is output as a result of transmission and reception of waves by a radio wave sensor mounted on a vehicle, a signal extraction unit configured to extract specific-intensity signals in a predetermined reflection intensity range from the detection signal group, and a determination unit configured to determine whether an occupant in the vehicle is in a first riding state in which the occupant is directly seated on a seat or in a second riding state in which the occupant is seated in an infant auxiliary device, based on a distribution mode of the specific-intensity signals.

  • Patent number: 10622658
    Abstract: A release layer of a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell comprises a cyclic olefin polymer comprising an olefin unit having a C3-10alkyl group as a side chain thereof. The release layer may have a glass transition temperature of about 210 to 350° C. The release layer may have a transition point of a dynamic storage modulus E? in a range from ?50 to 100° C. An ion exchange layer comprising an ion exchange polymer may be laminated on the release layer of the release film by a roll-to-roll processing to produce a laminate. The release film may be separated from the laminate to give the membrane electrode assembly. The release film achieves improved production of a membrane electrode assembly (an electrolyte membrane and/or an electrode membrane) of a polymer electrolyte fuel cell.

  • Patent number: 10283801
    Abstract: A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer containing an olefin unit having a C3-10alkyl group as a side chain thereof and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.
