Abstract: Network logical addresses are converted to temporary addresses which are more easily input using keys, typically ten keys, of mobile phones. Each character of the original address is replaced by a numeral, the numeral key being assigned to the character. In a certain phone, for example, key “2” is assigned to “2”, “A”, “B” and “C” and key “3” is assigned to “3”, “D”, “E” and “F”. If the original address includes “CE” as part of it, these two characters are converted simply to “23”. In the preparation step, the original addresses of web sites are converted to temporary addresses and the relation between them is registered in a table. By referring to the table, it would be easy to translate a temporary address to its original address so that correct access to the target site is enabled.

Abstract: A luminescent sheet for stamps comprising a subtrate and a luminescent layer formed on the surface of said substrate, characterized in that said luminescent layer contains fine particles of an inorganic fluorescent pigment, said fine particles being prepared by providing a dispersion containing particles having a mean specific surface area Sw.sub.2 of said inorganic fluorescent pigment in water, and subjecting said dispersion to wet-grinding to obtain an aqueous dispersion containing fine particles having a mean specific surface area Sw.sub.1 of said inorganic fluorescent pigment, and said fine particles satisfying the equation: 2.0.gtoreq.Sw.sub.1 /Sw.sub.2 .gtoreq.1.05.

Abstract: A selectively permeable membrane for an enzyme electrode is prepared by forming a mixture of an emulsion of resin containing at least one prepolymer or monomer having ethylenic unsaturation, and a water-soluble polymer material, and subjecting the mixture to irradiation with ionizing or ultraviolet irradiation. The membrane is permeable to substances produced by an enzyme reaction while preventing the permeation of higher molecular weight materials. An immobilized enzyme membrane is formed on an outer surface of the permeable membrane, and the resultant membrane is mounted on an electrically conductive base to form an enzyme electrode. In another embodiment, the selectively permeable membrane is formed on the electrically conductive base, and then the immobilized enzyme membrane is formed. The selectively permeable membrane is situated between the immobilized enzyme membrane, which is in contact with a sample solution, and the electrically conductive base.

Abstract: A heat-sensitive recording material comprising a support, a heat-sensitive recording layer containing a color former and a color developer forming color by the contact with the color former formed on the support, an interlayer containing a water-soluble resin or a water-dispersible resin as the main component formed on the heat-sensitive recording layer, and an overcoat layer formed by forming a layer containing (1) a macromonomer having a polymerizable functional group at one terminal of the molecular chain, the main component of the segment being organopolysiloxane and (2) a resin capable of being cured by electron beams on the interlayer and curing the layer by the irradiation of electron beams.
