摘要:
A process of producing a flame-retardant silane-crosslinked olefin resin, an insulated wire, and a process of producing an insulated wire. The process includes kneading and molding a silane graft batch containing a silane-grafted olefin resin in which a silane coupling agent is graft polymerized onto an olefin resin, a flame retardant batch in which an olefin resin is mixed with a flame retardant containing metal hydroxide, a catalyst batch in which an olefin resin is mixed with a silane crosslinking catalyst, and water crosslinking the batches after kneading and molding. A mass ratio of the flame retardant batch to the silane graft batch is 60:40 to 90:10, and the catalyst batch amount is 3 to 10 part by mass with respect to 100 part by mass of a component of the silane graft and flame retardant batches. The wire is prepared by covering a conductor with the silane-crosslinked olefin resin.

摘要:
A flat cable includes first and second insulator sheets, and a plurality of conductor elements arranged in parallel relation to one another over the length of the sheets. The first insulator sheet is provided with an adhesive layer. The conductor elements are interposed between the adhesive layer and the second insulator sheet. The first and second insulator sheets are first press-adhered under heat through the adhesive layer, and then bonded by an ultrasonic welding unit. The ultrasonic welding unit includes a horn for imparting ultrasonic oscillations, and an anvil placed in opposition to the horn. The first and second insulator sheets are bonded in the zones which extend along the length of the sheets and are located outside the loci where the conductor elements are arranged. The bonding is performed either continuously or in an intermittent manner.
摘要:
On a floor of a building, a wiring layout of information circuits which are used by personnel who work at a plurality of blocks, has at each block outlet connectors connected to information devices at the block. An interconnection unit has primary connectors connected to extend devices e.g. telephone exchange or network controller, and secondary connectors. Wiring structures each having a plurality of wiring cables connect respective groups of the secondary connectors to respective blocks. Interconnection cables detachably and interchangeably connect the primary and secondary connectors at the interconnection unit. To enable efficient and simple re-arrangement for the information circuits, first identification signs, e.g. colors, identify blocks associated with the respective wiring cables, and at the interconnection unit, the secondary outlets connected by one of the wiring structures to one of the blocks are grouped together in space and have associated with them an identification sign which is the same as the first identification sign identifying the block to which they are connected.

摘要:
A flat cable includes first and second insulator sheets, and a plurality of conductor elements arranged in parallel relation to one another over the length of the sheets. The first insulator sheet is provided with an adhesive layer. The conductor elements are interposed between the adhesive layer and the second insulator sheet. The first and second insulator sheets are first press-adhered under heat through the adhesive layer, and then bonded by an ultrasonic welding unit. The ultrasonic welding unit includes a horn for imparting ultrasonic oscillations, and an anvil placed in opposition to the horn. The first and second insulator sheets are bonded in the zones which extend along the length of the sheets and are located outside the loci where the conductor elements are arranged. The bonding is performed either continuously or in an intermittent manner. In a flat cable thus produced, the conductor elements embedded therein are efficiently prevented from mutual short-circuiting. Although the adhesive layer is made very thin, the insulator sheets are adhered to each other very firmly.
