Abstract: The aqueous ink of a pigment type comprises a pigment, water, a water-soluble solvent and a sulfite, and may further comprise a dispersant. An example of the dispersant comprises a copolymer of a monomer (a) represented by general formula (A), and one or more monomers (b) selected from the group consisting of compounds represented by general formulae (B) and (C): ##STR1## wherein AO represents an oxyalkylene group having 2 to 3 carbon atoms, and n represents an integer of 110 to 300.

Abstract: An aqueous ink for ink jet recording comprises a dye and a polymeric compound which can undergo a decarboxylation reaction. In an ink jet recording method, a recording operation is carried out by jetting a liquid droplet of the ink from a nozzle to a recording medium by using thermal energy.

Abstract: Disclosed is a thermal transfer recording medium comprising a substrate provided thereon at least an ink layer which is to be transferred by heat application, characterized in that the loss tangent (tan .delta.) of the ink layer in viscoelasticity measurement at a temperature of from 60.degree. to 100.degree. C. ranges from 0.4 to 2.5.

Abstract: A GPS receiver displays information concerning a distance to a destination and a direction with respect to the destination and the like. The information is provided according to a preset operating condition on the basis of data which include position data of the destination which is set in advance and position data of the current position which is obtained from radio waves emitted from GPS satellites orbiting the earth. The GPS receiver includes a memory which stores data of operating conditions corresponding to first, second, third and fourth operation modes. The parameters of the operating conditions of the four operation modes are different from each other in at least a part thereof.

Abstract: A developer composition comprising a carrier, whose surface layer comprises a silicone resin having a urethane bond, and a toner, which is little affected by environmental factors, so that it can develop good electrostatic latent images even under low-temperature and low-humidity conditions and under high-temperature and high-humidity conditions, to give high-quality prints.

Abstract: A developer composition for an electrostatic charge image, which comprises a toner comprising a binder resin and a coloring agent, and 0.1 to 1.0% by weight of fine polymer particles with a glass transition temperature of 90.degree. C. or higher deposited on the surface of the toner, the binder resin comprising, as a main component, a polyester resin with an OHV/AV value of 1.2 or more wherein OHV and AV represent the hydroxyl value and acid value of the polyester resin, respectively.

Abstract: A developer for electrostatic photography comprises toner and carrier coated with a composition comprising a silicone resin having (II) and (II') and at least one compound represented by following formula (III), (IV) or (V): ##STR1##

Abstract: A long life cleaning blade for image forming apparatus is formed of a rubber elastomer which contains, or has adhered on the surface thereof, an antistatic agent in an amount effective to prevent electrification.

Abstract: An electrophotographic developer composition comprises a binder resin, which comprises a polyester as the major component, said polyester obtained by co-condensation polymerization of(i) a diol component represented by the general formula: ##STR1## wherein R is an ethylene or propylene group and x and y are each an integer of 1 or more, with the proviso that the average sum total of x and y is 2 to 7, with(ii) a dicarboxylic acid, an anhydride or a lower alkyl ester thereof and(iii) a polycarboxylic acid having at least three carboxyl groups or an anhydride or a lower alkyl ester thereof or a polyhydric alcohol having at least three hydroxyl groups and having an OHV/AV value of at least 1.2 wherein AV is an acid value of the polyester and OHV is a hydroxyl value thereof, and at least two charge controllers.

Abstract: Disclosed herein is an electrochemical battery having electrodes immersed in an organic solvent electrolyte solution so that the electromotive force is generated by doping to and/or undoping from said electrodes.
