Abstract: A detection device detecting collapse of PM collected in a filter provided in an exhaust system flow path of an internal combustion engine includes: a differential pressure sensor configured to acquire a differential pressure between an exhaust inlet side and an exhaust outlet side of the filter; a water generation determination unit configured to determine whether water is generated in the exhaust system flow path; and a PM collapse determination unit configured to determine that at least a part of the PM collected in the filter has collapsed when a PM accumulation amount estimated based on the acquired differential pressure has increased by a predetermined amount or more within a predetermined period in a state where the PM accumulation amount estimated based on the acquired differential pressure is equal to or larger than a predetermined first threshold and the water generation determination unit has determined that water is generated.

Abstract: An information processing device includes a processor configured to provide an incentive to a first user who sells or returns a first vehicle in which a part of a first coating film including an easily peelable layer is not peeled off.

Abstract: A navigation server includes a processor. The processor is configured to derive one of a first route and a second route as a route from a place of departure to a destination of a vehicle in accordance with a remaining level of a travel battery of the vehicle. The first route includes a first road provided with a first non-contact electric power feeder. The second route includes a second road provided with a second non-contact electric power feeder that is different in electric power feed capability from the first non-contact electric power feeder. The processor is configured to output the derived route as a recommended route to a terminal associated with the vehicle.

Abstract: A terminal box that can be reliably fixed to a solar cell module is provided. The terminal box includes a bottom wall facing a back surface of the solar cell module, a top wall facing the bottom wall, side walls, and a housing space defined by the bottom wall, the top wall and the side walls to accommodate a component to be mounted. The bottom wall includes a limiting wall formed in a periphery of the bottom wall to project toward the solar cell module, and a communication opening for allowing a charging space defined by the limiting wall and the bottom wall to communicate with the housing space. The limiting wall defines a gap for allowing the charging space to communicate with external space of the limiting wall.

Abstract: An expandable polyurethane composition includes (A) polyisocyanate, (B) active hydrogen containing compound including (B1) polyol and (B2) water, a catalyst, and (C) one or more plasticizers selected from the group consisting of a monoester compound, a diester compound, a triester compound, and a tetraester compound by 0.5 to 20 parts by mass relative to 100 parts by mass of the (B1) polyol. A flexible polyurethane foam can be obtained of which wet set is improved and feeling is good.

Abstract: An expandable polyurethane composition includes (A) polyisocyanate, (B) active hydrogen containing compound including (B1) polyol and (B2) water, catalysts, and (C) cross-linking agent composition. The (C) cross-linking agent composition includes at least one kind of (C1) cross-linking agent selected from (CA) ethoxylate derivative having MW of 2000 or less and (CB) ester compound having MW of 2500 or less, and (C2) non-protic polar solvent, and a mass ratio ((a+b)/c) of a sum of content a of the (CA) ethoxylate derivative and content b of the (CB) ester compound relative to content c of the (C2) non-protic polar solvent is 1/10 to 10/1. A flexible polyurethane foam can be obtained of which wet set is improved and feeling is good.

Abstract: A thermally curable resin composition includes a linear thermally curable resin and amorphous silica fine particles having pore portions.

Abstract: An actinic energy ray-curable resin is obtained by reacting (c) an epihalohydrin with hydroxyl groups of a linear epoxy resin (A′) which is a product of the polyaddition reaction of (a) a bifunctional hydrogenated bisphenolic epoxy compound with (b) a compound having at least two carboxyl groups in its molecule to obtain a polynuclear epoxy resin (A″) having epoxy groups in its terminal and side chain and further reacting (d) an unsaturated monocarboxylic acid with an epoxy group of the polynuclear epoxy resin (A″) to introduce a photopolymerizable unsaturated group therein and further reacting (e) a polybasic acid anhydride with a hydroxyl group of the polynuclear epoxy resin to introduce a carboxyl group therein. A photocurable and thermosetting resin composition capable of being developed with an aqueous alkaline solution is obtained by mixing this actinic energy ray-curable resin with a photopolymerization initiator, a diluent, and a polyfunctional epoxy compound.
