An adherently bonded polycrystalline diamond body is produced by forming a charge composed of a mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy wherein the alloy is in contact or in association with hexagonal boron nitride, confining such charge within a reaction chamber, subjecting the confined charge to a pressure of at least 25 kilobars, heating the pressure-...

Disposable diapers having elasticized waistbands which allow the diapers to breathe and which reduce the incidence of waistband rollover. The waistbands are formed by affixing elastic elements between the topsheets and the backsheets (in the waistband region of the diapers) using regularly spaced, transversely extending regions of securement. Regions of nonsecurement are formed between pairs of th...

A sheet-retaining mat fitment has a sheet clamping member provided on the upper surface of a bag-like cover body with one side thereof open so as to be fitted on one end of a mat. After the sheet-retaining mat fitment is fitted on each of the ends of a mat, each end of a sheet is clamped by the corresponding sheet clamping member, thereby to attach the sheet to the mat.
