A Co&#x2014;Cr&#x2014;Mo alloy fine wire has superior biocompatibility, corrosion resistance, wear resistance, processability, and flexibility. A manufacturing method and a planar body or the like formed by processing this fine wire. This is a fine wire of diameter of 200 micrometers or less comprising 26 to 31 weight % of Cr, 8 to 16 weight % of Mo, and the remainder of Co and inevitable impurities, in which the degree of roundness (minor diameter/major diameter) of lateral cross section is 0.6 or more, and the internal structure is uniform with the concentration ratio of high Mo concentration phase to low Mo concentration phase of 1.8 or less.

Co-Cr-Mo alloy fine wire, manufacturing method therefor, and planar body, tubular body, stranded wire and cable formed of wire

The present invention provides a method for manufacturing a biomedical porous article wherein communicability between the pores in the porous article is ensured and a desired porosity can be easily obtained, the method comprising a plate-like thread cluster formation step in which a plate-like thread cluster is obtained by dispersing many metallic threads made of a biomedical metallic material along a flat surface and entangling them; a compressing step of compressing the plate-like thread cluster into a desired thickness; and a sintering step of sintering the plate-like thread cluster.

A Co&#x2014;Cr&#x2014;Mo-based alloy includes: 63 mass %&#x2266;Co&#x3c;68 mass %; 15 mass %&#x2266;Cr&#x3c;26 mass %; 10 mass %&#x2266;Mo&#x3c;19 mass %; and the balance of inevitable impurities, wherein the total amount of Cr and Mo is from 32 mass % to 37%. The mass magnetic susceptibility of the alloy is 7&#xd7;4&#x3c0;&#xb7;10m/kg or less at room temperature, and the Vickers hardness number (Hv) of the alloy is 400 or more.

Co-Cr-Mo-based alloy and production method therefor

There are disclosed a vinyl resin composition which comprises a resin composition comprising a vinyl polymer, a polyamideimide elastomer obtained by reacting a mixture of caprolactam, an aromatic polycarboxylic acid and a specified polyoxyethylene glycol, with 0-0.5 mole of a diamine, etc., per 1 mole of glycol contained in said mixture, the glycol component being present in a proportion of 85-30% by weight in said elastomer and the relative viscosity of the elastomer being at least 1.5 (at 30.degree. C.), and an electrolyte added as desired, and articles molded from the composition.

Vinyl resin composition

A polystyrene resin composition comprising a rubber-reinforced polystyrene, a fibrous potassium titanate and a higher fatty acid and/or its metal salt in specific proportions. The composition exhibits greatly improved stiffness without sacrificing its excellent impact strength, melt flowability and good appearance. The composition is useful as a material for manufacturing large-sized molded articles, such as parts and housings for large-sized TV sets and frames for air conditioners. The composition may further comprise a fire retardant and a carbon fiber in specific proportions. The resultant fire-retardant composition is not only excellent in the above-mentioned properties of mechanical strength but also exhibits excellent fire retardance and, therefore, is advantageously used as a material for manufacturing the above-mentioned articles especially when the articles are required to have high fire retardance.

Polystyrene resin composition having improved stiffness

A high-gloss, impact-resistant rubber-modified polystyrene composition, characterized in that said rubber-modified polystyrene consists essentially of
