Abstract: Disclosed is a film key sheet with a key top protruding from a resin film which allows a further reduction in thickness and provides a sufficient degree of clarity in visually recognizing a display portion thereof, and a method for manufacturing such a film key sheet. The film key sheet has a film removal hole piercing through the resin film, with a hole edge portion raised from the surface of the resin film being secured to the side surface of the key top. Thus, no resin film exists on the upper and bottom surfaces of the key top, so that it is possible to achieve a further reduction in thickness independently of the foldability of the resin film and drawing accuracy and to provide clarity in visual recognition of a display portion at the bottom of the key top.

Abstract: An upholstery tack strip includes a thermoplastic sleeve and a metal ribbon embedded within the sleeve. The sleeve itself includes a plurality of removed material sections forming opposed pairs of sleeve windows, while the metal ribbon integrally includes nail sections which protrude outwardly from the tack strip through respective ones of the sleeve windows.

Since the nail portions protrude outwardly from the tack strip through the sleeve windows, relative lengthwise slippage between the metal ribbon stock and the sleeve is prevented.

Abstract: A bulk modulus elastomeric element is employed in the present invention. The material from which the invention is fabricated is formed as a sheet, which has a plurality of channels that run through, or partially through it. The holes in the sheet are angled such that the remaining material may be of a parallelogram shape.

Abstract: An anti-erosion irrigation mat is fitted with parallel runs of drip line irrigation tubing and delivered in panels or rolls that can installed in a single operation instead of the two separate operations conventionally required for erosion prevention and irrigation. The drip line tubing runs are fitted with drip emitters at uniform intervals and are attached to the matting which may be made biodegradable for short term service, e.g. from biodegradable natural fibers, or made durable, e.g. from nylon filaments.
