Abstract: To provide a rubber composition excellent in elasticity and low loss property. A rubber composition comprising 100 parts by weight of a chloroprene rubber and from 1.2 to 3.0 parts by weight of cellulose nanofibers, characterized in that a vulcanized sheet obtained by vulcanizing the rubber composition has a 100% tensile stress (M100) increased by 1.5 MPa or more per part by weight of the cellulose nanofibers added, where the increase of M100 is calculated by subtracting M100 of a vulcanized sheet containing no cellulose nanofibers from M100 of the vulcanized sheet containing the cellulose nanofibers, and dividing the difference by the amount of the cellulose nanofibers contained.

Abstract: A gasket having a novel structure ensuring both the gas tightness and the low-friction slidability is provided. A sliding portion of the gasket (13) includes at least a first annular projection (17A), an annular recess and a second annular projection (17B) arranged in this order in a direction rearward from a distal portion of the gasket serving as a liquid contact portion. The first projection (17A) is designed so that a first peak appears adjacent the distal portion of the gasket when the gasket is fitted in the syringe barrel (11) and a product ? of a contact pressure P1f and a width D1f of the first peak is 0.4???1.0 as determined by an FEM analysis.

Abstract: It is an object to easily perform inspection and repair of a reactor cooling system that can cool a reactor for a long time without requiring electric power. An in-vessel heat exchanger disposed in the reactor is fixed to the inner side of an upper lid of a RPV, one of through-pipes piercing through the upper lid is connected to the in-vessel heat exchanger, and the other forms a connection element on the outer side of the upper lid. According to the present invention, it is extremely easy to perform inspection and repair of the reactor cooling system that can cool the reactor for a long period without requiring electric power.

Abstract: A nozzle cap (1) to be attached to a nozzle of a medical prefilled syringe is provided. The nozzle cap (1) includes a nozzle cap body, and a film (8) provided at least on an inner surface of the nozzle cap body. The film (8) has a liquid contact portion (6) to be possibly brought into contact with a liquid drug contained in the syringe, and a retention portion (7) to be brought into contact with an outer periphery of the nozzle. The liquid contact portion (6) of the film (8) has a greater thickness than the retention portion (7) of the film (8). The nozzle cap (1) for the prefilled syringe is excellent in sealability, and less liable to adversely influence a liquid drug contained in the syringe. A medical prefilled syringe is also provided, which employs the nozzle cap.

Abstract: The present invention provides a tobacco raw material having a good smoking flavor and a method for producing the same. Provided is a tobacco raw material having a ratio, which is expressed as “water-extracted material weight/hexane-extracted material weight,” between the weight of an extracted material obtained by extraction using n-hexane as a solvent and the weight of an extracted material obtained following the extraction by further extraction using water as a solvent, of 0 or more and 1.5 or less.

Abstract: A gasket (10) for a prefilled syringe is provided, which has a generally cylindrical outer shape, and includes a liquid contact portion (13) provided on one of opposite end faces, a thread hole (15) provided in the other end face for attachment of a plunger, and at least two annular projections (17A, 17B) provided on a peripheral surface (16) and spaced from each other by an annular trough (18) in a gasket height direction (gasket axial direction) extending from the one end face to the other end face, wherein a diameter difference (A) (=a1?a2) between a diameter (a1) of the annular projections (17A, 17B) and a diameter (a2) of the annular trough and a diameter difference (B) (=b1?b2) between a thread root diameter (b1) and a thread ridge diameter (b2) of an internal thread portion of the thread hole satisfy a ratio relationship of A:B=1:(2 to 4).

Abstract: A jet pump has a plurality of nozzles installed to a nozzle base, a throat and a diffuser. A first nozzle straight-tube portion, a first nozzle narrowing portion, a second nozzle straight-tube portion, a second nozzle narrowing portion, and a nozzle lower end portion formed in those nozzles are disposed in this order from the nozzle base to a ejection outlet. A narrowing angle of the second nozzle narrowing portion is larger than of the first nozzle narrowing portion. The jet pump forms, in a lower end portion of the throat, a flow passage narrowing portion having a flow passage cross-sectional area that gradually diminishes. This flow passage narrowing portion is inserted into an upper end portion of the diffuser.
