Abstract: A novel means for accelerating the flowering time in Rosaceae fruit trees such as apples and pears is provided, by inoculating a viral RNA into a cotyledon of a Rosaceae fruit tree seedling immediately after rooting with a particle gun technique, wherein the viral RNA is concentrated from a proliferating host infected with a recombinant apple latent spherical virus (FT-ALSV) expressing an Arabidopsis FT gene.

Abstract: An electrical insulating oil having a flash point (PMCC) of 130° C. or more and a pour point of ?40° C. or lower, comprising hydrorefined mineral oil and/or synthetic hydrocarbon oil and in the range of from 0.5 to 10 wt. % of bright stock oil, based on the total weight of the electrical insulating oil composition.

Abstract: A photovoltaic device that comprises an insulating transparent substrate coated with a light-receiving surface electrode formed of a thin metal film which in turn is overlaid with an amorphous semiconductor layer and a back electrode, said thin metal film being adapted for use as a mirror.

Abstract: An integrated photovoltaic device which comprises a plurality of amorphous silicon based solar cells each comprising on the light-receiving side of a common transparent substrate, a transparent electrode, a metal electrode on the transparent electrode, and an amorphous semiconductor layer interposed between the metal electrode and the transparent electrode, said plurality of solar cells being interconnected in a series or series-parallel fashion by means of said transparent electrode and said metal electrode, said metal electrode being formed of a metal film comprising, in superposition in order from the amorphous semiconductor layer side, layers of aluminum, an additive metal for aluminum bronze, and copper.
