摘要:
Fluorinated graphite fibers comprising an intercalated compound of graphite fibers having a three-dimensional crystal structure in which carbon hexagonal network faces are substantially in parallel with the axis of fibers and oriented in a coaxial manner and fluorine, wherein the length of repeating periods in the direction of C-axis of the crystals coexist within a range from 5 to 24 Å. The fluorinated carbon fibers are manufactured by graphitizing gas phase-grown carbon fibers obtained by thermally decomposing a hydrocarbon compound in a non-oxidative atmosphere under the presence of a catalyst supported on a substrate or bringing ultra-fine metal particles catalyst suspended in a high temperature zone into contact with a hydrocarbon compound, thereby obtaining graphite fibers having a three-dimensional crystal structure in which the carbon hexagonal network faces are substantially in parallel with the axis of fibers and oriented in a coaxial manner and then bringing them into contact with fluorine.

A metal-inorganic particle composite material 1 is heated into a melt 2. Flux 3 is thrown into the melt 2, and both the melt 2 and the flux 3 are brought into contact with each other sufficiently. The resulting melt 2 is then left at rest so as to be separated into an upper layer containing inorganic particles 2a and a lower layer composed of metal 2b. Subsequently the upper layer and the lower layer are recovered individually.

[Technical Problem] To remove a labor hour of attaching afterward the clamp to the corrugate tube, and to prevent the clamp from being displaced or loosening with respect to the corrugate tube. [Solution to Problem] A corrugate tube with a clamp 1, 1 2 integrally includes a straight tube portion 2, 5 and a bellows tube portion 3, 6, and a locking clamp 4 is integrally or individually provided on the straight tube portion. The straight tube portion which is provided with the clamp is thicker than the bellows tube portion. A slit 7 for inserting electric wires in a longitudinal direction of the tube is provided in an opposite direction of the clamp 4. A hole 8 for branching wires is provided communicating with the slit 7. A groove 42 or a hole 52 is provided on the straight tube portion 2 for fixing the individual clamp 43, 51. A radius d2 of a hill portion 10b of the bellows tube portion is sufficiently larger than a radius d of a valley portion 10a of the bellows tube portion, and a thickness T of the hill portion is gradually smaller as the bellows tube portion extends toward a tip. The bellows tube portions 3 are respectively arranged in between a plurality of straight tube portions 2, and the clamps 4 are provided on required straight tube portions.

A compound (1) is manufactured which has a metal outer part (3) having a hollow space (2) and a content material (4) formed in the hollow space (2). Namely, manufacture is made by including an outer part forming step to form an outer part and a content material forming step to form a content material (4) in the hollow space (2) by using a metal matrix melt to be die-molded and a filler contained in the melt. The outer part (3) has a desired exterior form. Meanwhile, the content material (4) is formed in a state the hollow space (2) is filled in order to lighten the weight and improve the strength of the compound (1).
摘要:
An insulating member is made of an abrasion-resistant resin composition prepared by mixing a base resin with a polyamide ultrafine fibers-dispersed polyolefin resin composition that contains a polyolefin, polyamide fibers, a silane coupling agent and silica particles. In the resin composition, the silica particles may be in the polyamide fibers.
