Abstract: In an approach for generating a user-specific personal corpus, a processor creates a basic corpus for a first user using a first set of data sources, wherein the basic corpus includes one or more basic words and one or more vectors of the one or more basic words. A processor extracts a set of text from a second set of data sources associated with the first user. Responsive to finding an unknown word included in the set of text extracted, a processor updates the basic corpus, wherein the basic corpus is updated by replacing a vector of the unknown word with an average vector of the one or more basic words in the basic corpus created and registering the unknown word in a first personal corpus.

Abstract: An electrophotographic apparatus including a cylindrical layered electrophotographic photoreceptor. Electrophotographic processing components are disposed in the vicinity of a peripheral surface of the photoreceptor. The apparatus forms images by operating the processing components while rotating the photoreceptor.

Abstract: An image forming apparatus includes an image bearing member; a latent image forming device for forming first and second latent images on the image bearing member; a developing device for developing the first latent image with first ink to form a first ink image, and developing the second latent image with second ink to form a second ink image; and a transferring device which transfers the first ink image onto a transfer member and then the second ink image onto the transfer member. The surface tension of the first ink is set higher than that of the second ink.

Abstract: The improved polyurethane resin has a number average molecular weight of 2,000-200,000 and is prepared by reacting an organic diisocyanate compound, a polymer diol compound, a chain extender and a terminator. It is characterized by having at least one group selected from hydrazine groups, hydrazide groups and semicarbazide groups in the molecule. The polyurethane resin can be produced using a chain extender and/or a terminator that have at least one hydrazine group or hydrazide group. This polyurethane resin can be dispersed in water in the presence of an emulsifier or by first introducing free carboxyl groups into the molecule of the resin and then dissolving or dispersing it in an aqueous alkali solution or by first introducing tertiary amino groups into the molecule of the resin and then dissolving or dispersing it in an aqueous acid solution. The water-based polyurethane resin can be used either as a binder for water-based printing inks or as a water-based laminating adhesive.

Abstract: Disclosed is a polyurethane resin which is a reaction product of a high molecular weight polyol compound having a molecular weight of 3,000 to 10,000, a low molecular weight polyol compound having a molecular weight of not more than 200, an organic diisocyanate compound, a chain extender, and optionally a reaction terminating agent, wherein the whole of the high molecular weight polyol compound and the low molecular weight polyol compound has an average molecular weight of 1,500 to 2,700; the isocyanate index (I.I.) of the organic diisocyanate compound to the high molecular weight polyol compound satisfies the following condition: I.I.>2.0; and the nitrogen content of the polyurethane resin derived from the isocyanate group of the organic diisocyanate compound is from 1.30 to 1.95% by weight.

Abstract: A modified chlorinated polypropylene which has superior properties is obtained by the reaction of a chlorinated polypropylene having a molecular weight in the range of from 5,000 to 500,000 with a polyurethane having a molecular weight in the range of from 600 to 200,000. The modified chlorinated polypropylene exhibits excellent adhesion to various kinds of base film and a satisfactory performance with respect to such after-treatments as lamination, boiling and retort processes, and therefore is useful as a binder resin for printing ink or other coating compositions.
