Abstract: A capacitor includes a capacitor body including a plurality of dielectric layers and a plurality of internal electrode layers being stacked alternately. The plurality of dielectric layers mainly include crystal grains containing barium titanate as a main component. The plurality of dielectric layers contain magnesium, a rare earth element, and manganese. The plurality of dielectric layers include oxide grains containing at least one of the magnesium, the rare earth element, or the manganese as a single element.

Abstract: A sealing device 30 for a packaging material 10, comprising a linear sealing device 31 for sandwiching layers to be sealed 11A, 12A of plastic sheets 11, 12 are sandwiched by sealing bars 41, 42 narrower than a sealing width, and pressuring the layers to be sealed in a heated state, a surface sealing device 32 for sandwiching the layers to be sealed 11A, 12A of the plastic sheets 11, 12 with sealing bars 51, 52 of a width necessary for sealing by the sealing width, and pressing the layers to be sealed in a melting state.

Abstract: A printing paper for thermal transfer printing comprising a substrate, and a dye acceptor layer formed on one surface of the substrate to accept a sublimable dye transferred from a dye carrier ribbon in contact with the dye acceptor layer upon selective heating of the dye carrier ribbon. The dye acceptor layer has a cumulative pore volume of 0.2 to 0.6 cm.sup.3 /g and contains a pigment in the form of particles whose median particle diameter of from 0.2 to 2 .mu.m. In particular, the dye acceptor layer is made of a coating of a resinous binder uniformly dispersing a pigment therein, the coating being impregnated with a resin having good affinity for the sublimable dye.
