The entire system is suitable for operation in rural areas having a low population density and urban areas where hours of peak call loading could otherwise be detrimental to call completions.

Abstract: An air/water-tight slide fastener has an end stop. The end stop has a flange portion extending therearoud. At least part of the flange is extensive enough to be integrally fixed to the opening edges of an opening formed in an article. Since the flange portion is firmly clamped by and between the air/water-tight fastener tape and the opening edges of the opening of the article; when the air/water-tight slide fastener is folded on itself; the excessive bending stresses exerted directly on the air/water-tight fastener tape is relaxed or mitigated. The air/water-tight fastener tape is thus prevented from being peeled off at that position.

Abstract: An abrasive substrate is removably provided between a head portion and an abrasive member in a carry type abrasive machine. The abrasive substrate is constituted by a single synthetic resin molded member formed of the same material, and a hardness in a peripheral portion is set to be lower than that in a central portion excluding the peripheral edge portion. A difference in the hardness between the central portion and the peripheral portion is regulated by a concavo-convex surface formed on a surface at the fixing side to the head portion of the carry type abrasive machine. It is desirable that the concavo-convex surface should be constituted by a plurality of rib-shaped projections formed on the same plane. The abrasive substrate of the carry type abrasive machine can be manufactured inexpensively and can carry out a reliable and stable abrasion work.
