  • Patent number: 10427828
    Abstract: A corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall and top flaps, and is formed, at the boundary area between the peripheral wall and the top flaps, with a groove-shaped reverse scoreline recessed on the side of an outer linerboard, and a pair of groove-shaped recesses recessed on the side of an inner linerboard, and extending in parallel to each other so as to sandwich the area in which the reverse scoreline extends. The corrugated paperboard box is further formed, in one of the groove-shaped recesses, with a perforated line along which the top flaps can be separated from the peripheral wall. The top flaps can be bent along the perforated line toward the inner surface of the peripheral wall.

  • Patent number: 5828117
    Abstract: The invention provides two kinds of structures for a thin-film solar cell that is improved in the adhesive strength and reflectance of a back surface electrode layer. According to the first structure, in a thin-film solar cell in which a transparent electrode layer, a thin-film semiconductor layer, and a back surface electrode layer are laid in stated order on an insulative transparent substrate, the back surface electrode layer consists of a first transparent conductive metal compound layer having a smaller refractive index than a semiconductor that constitutes the thin-film semiconductor layer, a second transparent conductive metal compound layer, and a metal layer. The second transparent conductive metal compound layer contains at least one of components of the first transparent conductive metal compound layer and a component of the metal layer.

  • Patent number: 5507880
    Abstract: A solar module made by the sequential stacking of a conducting metal oxide layer, an amorphous semiconductor layer, a back metal electrode, and a passivating resin layer on a transparent substrate, in which the passivating resin layer includes a water vapor barrier layer having a permeability to water vapor of not more than 1 g/m.sup.2 day measured at a thickness of 100 .mu.m, with the water vapor barrier layer being a polymer having a backbone consisting essentially of carbon and hydrogen. This barrier layer prevents the oxidation of the back metal electrode by water vapor, so that the stability of the module is improved in outdoor use.
