Abstract: A condensed heterocyclic compound has a sepiapterin reductase inhibitory action and is particularly useful for treatment of a pain. The condensed heterocyclic compound represented by Formula (I) below (R1 represents a hydrocarbon group or the like; R2 and R3 represent a hydrogen atom or the like; R4, X, and Y represent defined substituents), a tautomer or a pharmaceutically acceptable salt of the compound, or a solvate of any of these.

Abstract: A mold device includes a primary mold and a secondary mold. The primary mold includes a cavity mold and a primary core mold. The primary mold is configured to inject a first resin material into a first cavity to mold a primary molded product, the first cavity being formed by clamping the cavity mold and the primary core mold. The secondary mold includes the cavity mold and a secondary core mold. The secondary mold is configured to inject a second resin material into a second cavity to stack mold a secondary molded product on a peripheral edge of the primary molded product. The second cavity is formed by clamping the cavity mold and the secondary core mold. The cavity mold is configured to hold the primary molded product. The cavity mold includes a primary molded product holding portion configured to project into and retract from the first cavity, on a parting line of the primary mold.

Abstract: A cover body includes: a multi-color molded body including a first resin portion having a gate mark on an outer surface thereof, and a second resin portion having a color different from a color of the first resin portion and adhering to the outer surface of the first resin portion to cover the gate mark. An outer surface of the second resin portion includes a stepped portion that overlaps with the gate mark.

Abstract: A non-austemper-treated spheroidal graphite cast iron obtainable without being subjected to an austemper treatment. The non-austemper-treated spheroidal graphite cast iron has a tensile strength of 650-850 MPa and an elongation of 7.0-14.5%. In the non-austemper-treated spheroidal graphite cast iron, V-notch material has a fatigue limit of 290 MPa or more. The non-austemper-treated spheroidal graphite cast iron has well-balanced mechanical properties both in tensile strength and elongation and improved tensile strength and elongation than conventional one.

Abstract: An apparatus for externally supplementing an electrolyte into a matrix-type fuel cell constituted by a cell lamination composed of laminated cells each having a matrix impregnated with and holding an electrolyte, comprising an electrolyte source for sending the electrolyte under pressure, a header vertically provided along a side surface of the cell lamination for passing the pressurized electrolyte through the header from the electrolyte source, and supply pipes connected to the cells from the header for supplying the electrolyte to the matrices of the cells. The flow resistance in each of the supply pipes is selected to be greater than the flow resistance in the header.
