摘要:
A ceramics composite material containing crystallized glass as the matrix and fibers or whiskers of ceramics as a reinforcement material, is obtained by melting original glass to form crystallized glass, compounding the same with fibers or whiskers of oxide ceramics and thereafter crystallizing the original glass. This ceramics composite material does not form any voids and can easily contain at least 50 volume percent of the reinforcement material, whereby a good mechanical strength and fracture toughness are achieved. In the compounding step, the content of the reinforcement can be further increased by forcing out any excess part of the original glass from the reinforcement material by applying pressure to a substance obtained by mixing the original glass with the reinforcement. Further, the ceramics composite material can be efficiently formed into a desired configuration by heating because the original glass flows viscously.

A shielded electric wire 1A is composed of a plurality of covered electric wires 10 of which core wires 2 are covered by covers having different colors; a braided shield 4 attached to an outer region of the covered electric wires 10; and an insulating sheath 5 covering an outer circumference of the braided shield 4. Because the covered electric wires 10 have covers 3 having different colors, the covered electric wires 10 can be identified from each other. Further, a mark 6A for identifying the electric wire is formed on a part of the outer surface of the sheath 5. A color identifying a destination of each covered electric wire 10 is selected properly as the color of the mark 6A. Further, a combination of the colors of the covers 3 of the covered electric wires 10 and the color of the mark 6A can indicate a product type of the shielded electric wire 1A.

A surface acoustic wave device has a piezoelectric substrate whose properties include electromechanical coupling coefficient advantageous to widening passband width and SAW velocity advantageous to achieving a compact surface acoustic wave device. The piezoelectric substrate is composed of the single crystal represented by chemical formula Sr3TaGa3Si2O14 belonging to point group 32.

摘要:
A thin film layered member having high heat dissipation efficiency is composed of at least two diamond layers and at least one interlayer. The diamond layers and the interlayer ape alternately laminated and the diamond layers form outer surfaces of the thin film layered member. When this member is applied to a heatsink or the like, thermal stress to an element mounted thereon can be reduced because of a laminated structure comprising an interlayer having a high coefficient of thermal expansion and diamond layers having a low coefficient of thermal expansion. Further, the interlayer includes a carbide forming metal, which reacts with carbon atoms constituting a diamond in a laminating process and to form a carbide at an interface between the interlayer and the diamond layer, thereby realizing strong bonding therebetween.
