Abstract: There is provided a content output device including a selection unit which selects content according to a user's condition and a magnetic field pattern corresponding to the content, a content output unit which outputs the content, and a magnetic field generating unit which generates a magnetic field based on the magnetic field pattern.

Abstract: A display device, method, computer-readable storage medium and user interface, each of which detects contact to or proximity of an object with respect to a generated image, and responsive to detection of contact to or proximity of the object to the generated image, disables any operational functions associated with a first portion of the generated image. Additionally, operation associated with a second portion of the generated image is allowed responsive to the detection of contact to or proximity of the object to the generated image, where the second portion of the generated image is different from the first portion of the generated image. An indication corresponding to the second portion of the generated image for which operation is enabled may be displayed on the generated image.

Abstract: A self-water dispersible particle made of a biodegradable polyester and a process for the preparation of an aqueous dispersion of self-water dispersible particles made of a biodegradable polyester containing a hydrophobic core material, which comprises reacting a biodegradable polyester containing hydroxyl group with a polyvalent carboxylic acid or anhydride or chloride thereof, dissolving or dispersing the biodegradable polyester having acid groups thus obtained and a hydrophobic core material in an organic solvent, adding a base to the solution with stirring to neutralize to form the salt of the biodegradable polyester, and then adding water to the solution or dispersion to undergo phase inversion emulsification are disclosed.

Abstract: A novel process for the preparation of a high molecular lactic copolymer polyester is provided, which includes allowing a lactide (A), a polyester terminated by hydroxyl group at both ends (B1), a polyvalent carboxylic acid having 3 or more functionalities and/or acid anhydride thereof (C) to undergo ring opening copolymerization in the presence of a ring opening polymerization catalyst (D). A novel process is also provided which includes allowing the lactide (A) and the polyester (B1) to undergo ring opening copolymerization in the presence of the catalyst (D) to prepare a polyester, and then reacting the polyester with the component (C).

Abstract: The present invention provides a process for the preparation of a decomposable lactic copolymer polyester which exhibits a sufficiently high molecular weight, heat resistance and thermal stability and further exhibits a rigidity, flexibility and transparency depending on the purpose. The process for the preparation of a high molecular lactic copolymer polyester includes reacting a polyester terminated by hydroxyl group at both ends (B1) with a polyvalent isocyanate (E) having 2 or more functionalities to obtain a polyester (B4) having a weight-average molecular weight of from 10,000 to 300,000, and then allowing said polyester (B4) and lactide (A) to undergo ring opening copolymerization in the presence of a ring opening polymerization catalyst (D).

Abstract: A process for continuously producing a linear lactide copolymer having a weight-average molecular weight of from 20,000 to 400,000 using a continuous reaction apparatus composed of three or more stirred flow reactors connected in series, which process comprises the steps of continuously feeding from 50 to 98 parts by weight of a lactide and from 2 to 50 parts by weight of a polymer having a hydroxyl group in a molten state or as dissolved in a solvent to the first reactor of said continuous reaction apparatus, and transferring the reaction mixture from said first reactor to the following reactors successively while maintaining the reaction pressure and the reaction temperature in every reactor in the range of from 1 to 5 atm. and of from 140.degree. to 210.degree.
