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.

Abstract: There is provided a curable compound having good solvent solubility and being capable of forming a cured material having super heat resistance. The curable compound according to the present invention is represented by the following formula (1).

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.

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.

Abstract: Provided is a film, sheet, plate, or other such formed article having excellent transparency made of a copolymer obtained from a cyclic olefin monomer and an ?-olefin monomer. The present invention provides a formed article made from a copolymer having Tg of 170° C. or higher and an Al content of 50 ppm or less that is a copolymer including a structural unit of a cyclic olefin monomer (A) derived from norbornene and a structural unit of a monomer (B) derived from at least one C4-C12 ?-olefin.
