摘要:
A syringe cylinder 12 includes a groove 32 formed in an inner peripheral surface thereof and extending over a predetermined length from an opening end 30 thereof. Even with the intermediate sliding stopper 14 located at a position where the groove 32 is formed, the pressure inside the syringe cylinder 12 can be reduced. Thus, during vacuum tapping, the intermediate sliding stopper 14 can be held in the vicinity of the opening end 30 of the syringe cylinder 12. Consequently, the intermediate sliding stopper 14 can be inserted into the syringe cylinder 12 in a correct posture and reliably moved to a predetermined position in the syringe cylinder 12.
摘要:
In a prefilled syringe separately containing both a lidocaine solution and a hyaluronic acid solution, the viscosity of the hyaluronic acid solution is set so as to be sufficiently higher than the viscosity of the lidocaine solution. When lidocaine discharge from the tip of a hypodermic needle ends, the force f (N) required to discharge the hyaluronic acid solution from the needle tip suddenly increases, imparting sort of a jolt to the hand of the operator and creating a momentary sensation that the plunger is at rest. Letting the force f (N) required to discharge the lidocaine solution be P1 and the force f (N) required to discharge the hyaluronic acid solution be P2, the relationship therebetween is P1 0.2, the operator is able to feel a sufficient jolt.

摘要:
An outer tapered member (4) having a conical inner circumferential surface is placed and an inner tapered member (5) having a conical outer circumferential surface in contact with the conical inner circumferential surface is placed in a through hole (31) of a first ring (1). A screw member (6) is screwed a predetermined quantity into the through hole (31) to axially press an axial end face of the inner tapered member (5) toward a second ring (2) with a predetermined force and to press the outer surface of the outer tapered member (4) against the through hole (31) of the first ring (1) with a predetermined force. A weld part (7) in contact with a first ring (1) side end portion of a pin (3) and the first ring (1) is formed to prevent the pin (3) from coming out of the first ring (1) by the weld part (7).
摘要:
A thermoplastic resin composition comprising a thermoplastic resin (A) and a hydrogen donative material or Component (B) added in an amount of 0.01-40 weight parts per 100 weight parts resin (A), the hydrogen donative material having a transfer of hydrogen or at least 0.1 (hydrogen atoms/molecules anthracene). The composition further incorporates metal salts of aliphatic acid and/or hydrotalcites and a selected class of oxidation inhibitors.

An oil composition contains 100 parts by weight of a base oil selected from the group consisting of mineral base oil, synthetic base oil and mixtures thereof, and 0.1 to 20 parts by weight of a hydrogenated oil obtained by hydrogenating an oil selected from the group consisting of coal type tar, oil produced by fractionating coal type tar, a hydrocarbon obtained by thermally cracking petroleum and having a boiling point of not lower than 200.degree. C., a hydrocarbon obtained by catalytically cracking petroleum and having a boiling point of not lower than 200.degree. C., a hydrocarbon obtained by catalytically reforming petroleum and having a boiling point of not lower than 200.degree. C., and mixtures thereof, whereby the hydrogenated oil has the hydrogen-donating properties of not lower than three times the hydrogen-donating properties of the base oil at temperatures of not lower than 350.degree. C.
摘要:
A supporting bearing is replaced with a new supporting bearing by conducting a first step and a second step. In the first step, an old inner ring before replacement is replaced with a new inner ring having an inner ring raceway diameter same as the old inner ring, and an axial length of an inner ring raceway face longer than the old inner ring so that a rolling roll is supported by this new inner ring in combination with an old outer ring and old cylindrical rollers. Thereafter, in the second step, the old cylindrical rollers are replaced with new cylindrical rollers having an axial length longer than the old cylindrical rollers, and simultaneously, the old outer ring is replaced with a new outer ring having an axial length of an outer ring raceway face longer than the old outer ring.
摘要:
In an optical head operable to record to and read from an optical recording medium, a beam emitted by a light-emitting element is reflected toward the light-emitting element by a first reflective mirror, and this reflected beam is reflected toward the optical recording medium by a second reflective mirror and focused on a recording surface of the optical recording medium. In this case, the first reflective mirror blocks a principal ray of the beam traveling toward the optical recording medium from the second reflective mirror, and the second reflective mirror consists of a plurality of concentric annular mirrors centered on the principal ray of the beam and separated from each other by a predetermined interval.
摘要:
A rubber composition comprising a naturally occurring and/or synthetic rubber and a selected amount of a hydrogen donor material having a hydrogen transfer (hydrogen atom/mol anthracene) of at least 0.1. The composition is highly stable during molding and in use under severe temperature and shearing conditions and substantially immune to deterioration by heat or radiation and ultraviolet rays.
摘要:
A method of pre-heating feed water for boilers is disclosed which utilizes the exchange of heat between the tube side of a heat-exchanger which contains de-salinated and de-ionized water and the shell side which contains hydrocarbon vapors boiling in the range of 90.degree. to 150.degree. C. The tubes are made of carbon steel with their outer surfaces aluminized.
