Abstract: To reduce data amount while ensuring tactile reproducibility of a two-dimensional tactile signal, and improve the efficiency of a system related to tactile reproduction. Coding is performed to compress information amount by orthogonally transforming a two-dimensional tactile signal based on a time signal. By orthogonally transforming a two-dimensional tactile signal based on a time signal, it is possible to compress information amount by removing frequency components that are difficult for humans to perceive, as in the case of an image signal, for example. Accordingly, it is possible to reduce data amount while ensuring tactile reproducibility of a two-dimensional tactile signal, and improve the efficiency of a system related to tactile reproduction.

Abstract: To reduce a data amount required for tactile presentation while enabling driving of different types of tactile presentation devices corresponding to different physical amounts. An encoding device according to the present technology is provided with an encoding unit that generates coded data by performing encoding to compress an information amount by utilizing an interconversion property between physical amounts on a plurality of tactile signals representing different physical amounts. This makes it possible to obtain the tactile signals representing desired physical amounts within a range in which interconversion may be performed while compressing the information amount by utilizing the interconversion property between the physical amounts.

Abstract: Provided herein is an improved self-adhesive sheet composed of a base member having a water-soluble polymer layer on its reverse side and a release member, with a pressure sensitive adhesive layer interposed between them, in which the bond strength between the water-soluble polymer layer and the pressure sensitive adhesive layer remains high. It can be stuck readily without moistening; and yet it can be peeled off easily simply by dipping in water.

Abstract: Disclosed are an adhesive sheet comprising a release sheet base material, an undercoat layer formed on the release sheet base material, a release agent layer formed on the undercoat layer, an adhesive layer formed on the release agent layer and a surface sheet formed on the adhesive layer, the adhesive sheet being characterized in that the undercoat layer comprises a water-dispersible acrylate or methacrylate copolymer resin having an emulsifier content of about 2 to about 10 wt. % based on the total amount of the monomers used for preparing the copolymer and which resin has a glass transition temperature of about -60.degree. to about 20.degree. C., and that the release sheet base material having the undercoat layer formed thereon, as a whole, has a bulk density of up to 1.0 g/cm.sup.3, and a process for preparing a release sheet comprising a release sheet base material, an undercoat layer and a relase agent layer.

Abstract: A non-adhesive coated area substantially accurately coinciding with the width of a blade is formed on an adhesive sheet fabricated by forming the adhesive layer by coating an adhesive on the entire one side surface of a release sheet, scraping the adhesive layer by a blade having a suitable width to form a non-coated area in the adhesive layer, and then bonding a surface sheet to the adhesive layer having the non-coated area.
