摘要:
The present invention provides a novel brake hose capable of sufficiently satisfying the fatigue resistance and the corrosion resistance, with the excellent expansion resistance. In a brake hose comprising a first reinforcing fiber layer (2), an intermediate rubber (3), a second reinforcing fiber layer (4), and an external layer rubber (5) provided successively on the outer circumference of an internal layer rubber (1) for filling a brake fluid, the first reinforcing fiber layer (2) is made of a polyethylene-2,6-naphthalate fiber. Accordingly, all of the fatigue resistance, the corrosion resistance and the expansion resistance can both be realized at a high level.

A dental restorative material is disclosed, comprising an amorphous inorganic material having a refractive index in a D-line of sodium in the range of 1.470˜1.520 and having an X-ray opacity; a (meth)acrylic ester monomer not having a benzene ring in a molecule thereof; and a polymerization initiator, if desired, the dental restorative material according to the invention further comprises an amorphous inorganic material having a refractive index in a D-line of sodium equal to or less than that of the (meth)acrylic ester monomer not having a benzene ring in a molecule thereof, the dental restorative material of the invention has an X-ray opacity and translucency close to natural teeth, and has superior esthetics not using a monomer having a benzene ring which has a fear of an environmental hormone action.
摘要:
A dental filling resin composition is disclosed, comprising: a reaction product between an aluminosilicate glass powder containing at least one element selected from Ca, Sr, and Ra and an organic acid containing one or more carboxyl groups in one molecule thereof, a methanol-insoluble polymer, a monomer containing at least one unsaturated double bond and having no acidic group, and a polymerization initiator, and optionally a filler.The dental filling resin composition of the invention has not only superior mechanical characteristics and esthetics but also an ability to release a fluorine ion and therefore, can be suitably used for a wide variety of clinical applications such as filling restoration of tooth, core construction, or sealing of pit and fissure.
摘要:
An austenitic steel comprising Ni of 9-30%, Cr of 10-23%, and Fe of at least 45%, is characterized in comprising enough Cr and Ni to form whole austenitic structure in the equilibrium diagram at 700.degree. C., having austenitic phase at room temperature, and the austenitic phase is a single crystal, and has superior resistance against stress. The austenitic steel preferably comprises C.ltoreq.0.1%, Si.ltoreq.1%, Mn.ltoreq.2%, Ni 9-15%, Cr 16-18.5%, and at least one of elements selected from the group of Mo 1-3%, Ti 0.05-1%, and Nb 0.1-1.5%. The alloy is useful as a material for members of a reactor core of a nuclear reactor.
摘要:
Downward force resulting from the block mold and its carrier of the upper mold assembly which move downwardly toward the upstream end of the mold cavity defined by the vertically spaced-apart upper and lower mold assemblies is transmitted to the block mold and its carrier of the upper mold assembly passing the upward path extending upwardly from the downstream end of the mold cavity so that the distortions of the cross-sectional configuration and size of the mold cavity due to the weight of the block molds and their carriers are prevented.
摘要:
A mat unit for a bed may be selectively inflated or deflated, to change the posture of an individual lying on the bed, in a natural and gentle manner. A plurality of such mat units may make up a bed. Selective inflation and/or deflation of any number of these mat units may be controlled to change the posture of, and even turn over, an individual who is seriously handicapped or extremely bedridden.
