Abstract: A thermosensitive recording material including a support, a thermosensitive recording layer composed mainly of a leuco dye and a developer, provided on one surface of the support, and a back layer provided on the other surface of the support, wherein the back layer contains an isobutylene-maleic anhydride copolymer ammonium salt, and at least one of an aziridine compound, and a cross-linked product of the isobutylene-maleic anhydride copolymer ammonium salt and the aziridine compound.

Abstract: The present invention provides a thermosensitive recording medium including a white plastic support, a thermosensitive recording layer containing a binder resin as a binding agent, a colorless or pale color leuco dye and a color developer for heat-developing the leuco dye, a protective layer, and a back layer containing an electron-conductive needle filler and an ion-conductive polymer, wherein the thermosensitive recording layer is disposed on the white plastic support, the protective layer is disposed on the thermosensitive recording layer, and the back layer is disposed on a side of the white plastic support opposite to the side where the thermosensitive recording layer is disposed.

Abstract: To provide a thermosensitive recording material that is superior in uniformity, makes it possible to obtain images with high glossiness and has less curl, in which a synthetic paper having a multilayer structure serves as a support. Specifically, there is a thermosensitive recording material including: a support, and a thermosensitive recording layer containing a leuco dye and a color developer on the support, wherein the support is a synthetic paper having a multilayer structure, and an inorganic pigment is contained only in a base layer of the synthetic paper; also, two layers which are formed solely of polypropylene and which contain no inorganic pigment are laid one on top of the other on the base layer containing an inorganic pigment; further, all layers are biaxially stretched.

Abstract: The present invention relates to a universal rolling machine wherein a pair of left and right vertical rolls, which are positioned on axial centers that intersect axial centers of a pair of upper and lower horizontal rolls, are mounted coaxially within vertical roll chocks, and the vertical roll chocks are each arranged within a housing in a freely slidable manner along a direction of rolling of a material to be rolled. Assemblies each comprising a circular cylindrical nut and a screw are arranged on either side of the vertical roll chocks along the direction of rolling in spaces between the housing and the vertical roll chocks, as a movement mechanism for the vertical roll chocks. The provision of this configuration enables the use of conventional vertical roll chocks, ensures sufficient mechanical strength with respect to the reactive forces applied to the vertical rolls during the rolling, enables a reduction in costs, and also enables a significant shortening of the time required for replacing the rolls.

Abstract: An edging roll for rolling a shape having a web and flanges, including a main shaft having an eccentric shaft portion; an eccentric sleeve having an eccentric portion facing the eccentric shaft portion of the main shaft; web-restricting rollers attached to the eccentric shaft portion of the main shaft and the eccentric portion of the eccentric sleeve through bearings; flange rolling rolls attached to the main shaft and the eccentric sleeve through bearings; a flange rolling roll drive means having a pair of gear transmission means, a connection shaft, and a rotation drive means; a roll height adjustment means for integrally rotating the main shaft and the eccentric sleeve; a roll-width adjustment means for synchronously and mutually moving the main shaft and the eccentric sleeve; and further a roll width/height adjustment synchronizing means and a pair of guide rings may also be disposed.

Abstract: An image transfer type thermosensitive recording medium comprising a substrate and a double-layered thermal transfer ink layer formed thereon, which comprisees (i) a first layer formed on the substrate, comprising a thermofusible material and an oil component, which first layer melts to become a liquid having a low viscosity when heated to a predetermined temperature, the oil component comprising as the main components hydrocarbon of methane series and cycloparaffin, and having a viscosity of 100 cst or less at 40.degree. C. and a viscosity of 20 cst or less at 100.degree. C., and (ii) a second layer formed on the first layer, comprising a thermosoftening resin and a coloring agent, which second layer becomes soft, without being melted at the predetermined temperature or higher.
