摘要:
A composite carbonaceous heat insulator which comprises a carbonaceous heat-insulating member having a bulk density of 0.1 to 0.4 g/cm3, a carbonaceous protecting layer having a bulk density of 0.3 to 2.0 g/cm3 and comprising a carbon fiber structure and a thermally decomposed carbon penetrated into the structure, and a thermally decomposed carbon coating layer having a bulk density higher than that of the carbonaceous protecting layer, wherein the above carbonaceous protecting layer is jointed to at least a part of the carbonaceous heat-insulating member to form a jointed body, and the thermally decomposed carbon coating layer is formed at least on the face of carbonaceous heat-insulating member in the surface of the jointed body; and a method for manufacturing the insulator. The heat insulator is reduced with respect to the depletion, deterioration and pulverization during the use thereof, while maintaining excellent insulating characteristics.

摘要:
The present invention is a process for modifying the properties of a porous freeform fabricated part by increasing its density and reducing its porosity. The porosity and density of a freeform fabricated part are altered by packing the pores in a freeform part with an infiltrant, such as a preceramic polymer. The process includes drawing a vacuum on or pressurizing the freeform part while it is in an infiltrant bath, thereby forcing the infiltrant into the pores of the freeform part. After removing the densified freeform part from the infiltrant bath, the freeform part is subjected to a treating process, such that the infiltrant within the pores transforms to a ceramic or ceramic-containing phase to thereby increasing the density of the freeform part.

摘要:
A perovskite-containing composite material comprising a substrate, an intermediate layer of a first titanium-containing perovskite and a covering layer of a second perovskite, both the first and the second perovskites being quaternary or higher-substituted perovskites. This composite material exhibits a single-phase perovskite covering layer and, consequently, can very suitably be used for the manufacture of electronic components and modules comprising integrated passive components. A description is given of a method of manufacturing said composite material.

A gold paste for painting glass or a ceramic, exhibits gold color by being sintered. The gold paste comprises metal components having a metal composition within the following range: gold 82.0-99.1% by weight, bismuth 5.0-0.4% by weight, silicon 3.0-0.2% by weight, and the total amount of zirconium and/or aluminum 10.0-0.3% by weight. According to this, it is possible to provide a gold paste making it possible to form a gold-decorated portion which does not generates conductivity, neither generates spark nor is damaged even if it is exposed to a microwave that a microwave oven emits, is good in a massive feel and development of gold color, and has high-class feeling; and a gold-decorated product using this paste.

The method of the present invention has the steps of (a) flash evaporating a conjugated material in an evaporate outlet forming an evaporate; (b) passing the evaporate to a glow discharge electrode creating a glow discharge conjugated monomer plasma from the evaporate; and (c) cryocondensing the glow discharge conjugated monomer plasma on a substrate and crosslinking the glow discharge conjugated monomer plasma thereon, wherein the crosslinking results from radicals created in the glow discharge conjugated monomer plasma and achieves self curing.
摘要:
Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through a binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.
摘要:
Multi-functional materials are classified into those which have a photocatalytic layer with a photocatalytic function directly disposed on the surface of a base and those which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through a binder layer interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer has a structure in which fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.
