Disclosed herein is a plated-polyester article with a plating layer formed on the surface of a polyester article. The polyester article is irradiated with ionizing radiation to crosslink a polyester resin, the arithmetic mean roughness Ra of the surface of the plating layer is at most 1 &#x3bc;m, and adhesion strength between the polyester article and the plating layer is at least 2 MPa. A production process of a plated-polyester article, which comprises the step of melt-forming a resin composition obtained by dispersing an inorganic filler having an average particle diameter of 1 to 10 &#x3bc;m in a proportion of 5 to 20 vol. % in a polyester resin, which can be crosslinked by irradiation with ionizing radiation, into a polyester article, is also disclosed.

Plated-polyester article and production process thereof

A cable reel of an electric signal transmission apparatus includes a tape-shaped cable for absorbing a relative rotation by tighting and loosening of the windings of the tape-shaped cable, a housing including an inner cylinder having a flange portion and an outer cylinder having side and bottom surface portions, wherein an upper portion of the side surface portion is engaged with and covered by the flange portion of the inner cylinder.

Cable reel of electric signal transmission apparatus

A cable reel using a tape-shaped cable including a high-strength conductor having a tensile strength of 500 to 1500 N/mm.sup.2, an elongation percentage of 0.5 to 50% and a spring limitation value of 400 to 2000 N/mm.sup.2. Accordingly, in such a cable reel, weight as well as cost of the whole or parts in a cable reel can be reduced.

Cable Reel

A molding of modified polyphenylene oxide resin comprises a composite of modified polyphenylene oxide containing polyphenylene oxide having structure expressed in the following general formula (I) as a basic skeleton, which resin composite preferably contains a cross linking agent, more preferably phosphoric ester serving as a cross linking agent, while the molding is cross-linked by irradiation to ionizing radiation: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represents univalent substituents selected from a group of hydrogen, alkyl group, halogen, alkoxyl group and haloalkoxyl group, and n represents a natural number.
