A hygienic disposable article used as a diaper and possessing an absorbent body enhanced with expandable material. The expandable material is to be applied along the direction of the longitudinal axis of the diaper, in decreasing quantity outwards from the crotch area in such a way that the concentration of the expandable material in the crotch area is 8% to 40% of the weight of said absorbent bod...

An improved focus and tracking error detection circuit for an optical disk servo system. The circuit calculates the logarithm of the signal from each of at least a pair of photodetectors. The difference between two logarithmic signals is then determined to give an error signal. The invention takes advantage of the property of logarithms that the difference between two logarithmic signals is equiva...

A microporous liquid impermeable but vapor permeable sheet material useful as a backsheet for disposable absorptive devices such as disposable diapers, incontinent devices, sanitary napkins, and panty liners is disclosed. This backsheet provides unexpected useful attributes such as compatibility with available closure tapes and embossibility with translucent patterns.

An adjustable and reusable diaper comprises an inner pad made of absorbent material, and an outer panel defining a front flap with a first waistband portion and a rear flap with a second waistband portion. Five Velcro strips are respectively attached to the outer face of the first waistband portion and to the inner and outer faces of the two end sections of the second waistband portion. These Velc...

This invention relates to protective coatings for copper oxide superconductors. The coatings are formed by applying solutions of silica precursors to the superconductor and after solvent evaporation, heating in an oxygen-containing atmosphere to effect conversion of the precursor to a continuous silica coating. Precursor materials, such as hydrogen silsesquioxide, ethyl polysilicate and C-resin ar...

A disposable absorbent article, such as a diaper, is disclosed. The topsheet of the diaper is elastically extensible and provides a relatively low contact pressure against the skin of the wearer at relatively high elongations. This arrangement provides a diaper topsheet which can be elongated to conform to the shape of the wearer without causing undue discomfort or irritation. The relatively low u...

A disposable absorbent article such as a diaper (10), is disclosed. The diaper has two lengthwise extending longitudinal marginal portions (50), each longitudinal marginal portion having two elastically extensible leg cuffs, a barrier cuff (62) and a gasket cuff (56). The leg cuffs (56,62) serve to help contain body exudates within the disposable article. Each leg cuff (56,62) is elasticized to pr...

Novel azeotrope-like compositions comprising 1,2-difluoroethane and dichlorotrifuoroethane which are useful in a variety of industrial applications including refrigerant applications, solvent applications, and blowing agent applications.

A method for rapid acquisition of multiple GPS signals builds upon fast Fourier transformation of input GPS signals to simultaneously track multiple satellites and derive psuedorange measurements that are suitable for navigation solution. The method utilizes 2M samples of the reference signal with N samples of the signal set from the satellites (one millisecond of actual data) to directly compute ...

PURPOSE: To obtain a homogeneously needled three-dimensional structure excellent in heat resistance and suitable for high-performance brake elements, rocket motor parts, etc., by superimposing intermediate textile elements subjected to napping and successively needling the superimposed elements. CONSTITUTION: Warp yarns 12 and weft yarns 13 each comprising multifilament yarns such as polyacrylonit...
