摘要:
Silicon carbide-based fine particles containing an electrically conducting inorganic substance and a electromagnetic wave absorbing material, which are fine particles comprising a particle inner portion of a silicon carbide-based material and a surface layer formed of an electrically conducting inorganic substance mainly comprising carbon, wherein a gradient layer with the compositional ratio of the electrically conducting inorganic substance gradiently increasing toward the particle surface is present and the thickness of the electrically conducting inorganic substance gradient layer is from 1 to 500 nm. The electromagnetic wave absorbing material of the present invention can selectively absorb a electromagnetic wave of 1 to 300 GHz in a wide band.

Disclosed is a tubular knit glove and method of flatbed knitting. The outward portion of a thumb pouch (7) is knitted while the direction of the wales continues from the end of a four finger body (6) with a reciprocating motion in the direction of the course. Rows of stitches are knit in the center and yarn-overs (8,9) are added on each side as connecting stitches. The inward portion of a thumb pouch (10) forms rows of stitches that link with the yarn-overs (8,9) when knitting back from the end of the outward portion of the thumb pouch (7). After forming a thumb pouch (11), a five finger body (14) is knit as a circularly-knit tube wherein the knitting thread revolves in the course direction completing a glove (1).
摘要:
To provide a tubular knitted fabric and a knitting method thereof, which can be knitted without sewing by a flatbed knitting machine, and which is easily fitted to a three dimensional shape of a wearing region without detriment to appearance.As shown in (a), an outward side of thumb pouch 7 is knitted so as to continue in its wale direction to an end portion of a four finger body 6 and while repeats reciprocated knitting in its course direction. In the course direction, a row of stitches is formed in midway and hanging stitches 8, 9 are added on both sides respectively as stitches to be used for linking. In order to make the knitting needles that suspend the hanging stitches 8, 9 different from each other, the position of the row of stitches is shifted in a direction away from a knit end of the four finger body 6. As shown in (b), when a homeward side of thumb pouch 10 is knitted so as to be folded back from the edge portion of the outward side of thumb pouch 7, row of stitches are formed so as to link between the hanging stitches 8, 9. As shown in (c), after forming the thumb pouch 11 as a tubular knitted fabric by the flechage knitting with shifting of the row of stitches, a glove 1 is completed by knitting a five finger body 14 as a tubular knitted fabric by the round knitting in which the knitting yarn rounds to the course direction.
摘要:
A laminated body obtained by forming a metal-deposited layer onto one or both adhesion-improved sides of a polyimide film with improved adhesion obtained by coating and spraying an organic polar solvent solution containing a polybenzimidazole onto one or both sides of a self-supporting film prepared by casting and drying a dope, which is an organic polar solvent solution of a polyimide precursor which may contain an imidization catalyst, onto a support and then heat treating the film to form a multilayer polyimide film of a base polyimide layer and one or two polybenzimidazole layers, by vapor deposition or sputtering, and then plating with metal to form a metal layer onto the metal-deposited layer.
摘要:
A polyimide film with improved adhesion obtained by forming a thin polybenzimidazole layer on one or both sides of a polyimide film, a process for fabrication of a polyimide film with improved adhesion whereby an organic polar solvent solution containing a polybenzimidazole is coated or sprayed onto one or both sides of a self-supporting film prepared by casting and drying a dope, which is an organic polar solvent solution of a polyimide precursor which may contain an imidization catalyst, onto a support, and the film is then thoroughly heat treated, a cover lay film obtained by laminating a cover lay film adhesive onto the polyimide film with improved adhesion, and a laminated body employing the polyimide film with improved adhesion. The polyimide film exhibits the excellent characteristics of aromatic polyimide films including thermal properties, physical properties and electrical properties, while also having satisfactory adhesion.
