Abstract: An organic light-emitting device containing both a compound represented by the following general formula (1) and a compound represented by the following general formula (2) has a high light emission efficiency. The rings a to c each are a benzene ring that can be optionally condensed, R1 and R2 each represent a substituted or unsubstituted aryl group, etc., four of R31 to R35 each are a substituted or unsubstituted carbazol-9-yl group, but all of these four are not the same, and the remaining one is a hydrogen atom, a cyano group, etc.

Abstract: A lid material for PTP contains a polypropylene-based resin having a weight-average molecular weight of 2.0×105 to 3.5×105 and has an enthalpy of crystal fusion of 70 J/g or more as measured by a differential scanning calorimeter (DSC).

Abstract: Provided is a lid material for a press-through pack package, comprising a heat-seal layer composed of a heat-sealing agent and a lid material film, wherein the heat-sealing agent contains an adhesive resin having a ratio E1/E2 of a storage elastic modulus at 30° C. E1 to a storage elastic modulus at 60° C. E2 of from 4.0 to 20.0 and a ratio E2/E3 of E2 to a storage elastic modulus at 80° C. E3 of from 1.3 to 4.0. Also provided is a lid material for a press-through pack package, comprising a heat-seal layer composed of a heat-sealing agent and a lid material film, wherein the heat-sealing agent contains an adhesive resin having a melting point of from 40° C. to lower than 90° C.

Abstract: The present invention provides a vaccine for the bacterial cold-water disease in fish comprising inactivated cells of Flavobacterium psychrophilium in the logarithmic growth phase or components thereo

Abstract: This invention provides a method of preventing loss of muddy water used in boring a hole in the ground by a drill bit or the like with the muddy water introduced into the hole to stabilize hole walls and to remove slime resulting from the boring. When the muddy water is getting lost to the soil, a chemical liquid comprising an isocyanate compound or including an isocyanate compound as a main component is introduced along with a fibrous filler to a depth of the hole. The position from which the muddy water is leaking is filled with the fibrous filler and is sealed with a cured product of the chemical liquid.
