Abstract: Provided is a fluoroelastomer crosslinkable composition comprising a fluoroelastomer (a) and a cross-linking agent (b), wherein the cross-linking agent (b) is at least one selected from the group consisting of: a compound (b1) having 2 or more aromatic rings, 2 or more hydroxy groups directly bonded to carbon atoms constituting the aromatic rings, and 1 to 6 substituents (?) directly bonded to carbon atoms constituting the aromatic rings for which the value of at least one of the Hammett's substituent constants, ?m and ?p, is 0.03 or more (excluding a bromine atom, an amino group, a sulfanyl group, an acid group, and a group having a group containing these groups); and a salt of the compound (b1) with an alkali metal, an alkaline earth metal, or an onium compound.

Abstract: A member to be compressed for an electrochemical device obtained by crosslinking a crosslinkable composition containing a fluorine-containing elastomer containing a unit based on at least one crosslinkable group-containing monomer selected from the group consisting of a crosslinkable group-containing monomer (1) represented by the general formula (1): CX12?CF—Rf1—X2 wherein each X1 independently represents H or F, and Rf1 represents a fluorinated alkylene group or a fluorinated oxyalkylene group, and X2 represents I or Br; and a crosslinkable group-containing monomer (2) represented by the general formula (2): CX32?CX3—Z1—CX3?CX32 wherein each X3 independently represents H, F, an alkyl group or a fluorinated alkyl group, and Z1 represents an alkylene group, a fluorinated alkylene group, a cycloalkylene group, a fluorinated cycloalkylene group, an oxyalkylene group or a fluorinated oxyalkylene group.

Abstract: An engine-driven-DC-supply unit, including: a main component supported by a base member; and a mount member connected to the base member and supporting an engine body and an electric generator of the main component through four elastic bodies. The engine-driven-DC-supply unit is configured to convert electric power generated by the electric generator driven by the engine body to DC power, and to supply the converted DC power to an external load device. The four elastic bodies are located at four points. A distance between any two of the four points located in a first direction, which is along an axis of a crankshaft of the engine body, is larger than a distance between any two of the four points located in a second direction that is orthogonal to the first direction. The four points surround a barycenter of the main component in a plan view.
