Abstract: A semiconductor device includes a first-conductivity-type semiconductor substrate, a first first-conductivity-type semiconductor layer, a second first-conductivity-type semiconductor layer, a second-conductivity-type bottom layer, a Schottky metal, and a cathode electrode. The first first-conductivity-type semiconductor layer is provided on the semiconductor substrate and has a lower first-conductivity-type impurity concentration than the semiconductor substrate. The second first-conductivity-type semiconductor layer is provided on the first first-conductivity-type semiconductor layer and has a higher first-conductivity-type impurity concentration than the first first-conductivity-type semiconductor layer. The Schottky metal is provided on the second first-conductivity-type semiconductor layer. The Schottky metal contacts with partly the first first-conductivity-type semiconductor layer.

Abstract: An editing apparatus forms an output video signal by effecting an editing processing on a plurality of video signals such as first and second input video signals. There are generated first and second video clips representing a starting position and an ending position set to the first input video signal, third and fourth video clips representing a starting position and an ending position set to a second input video signal, and fifth and sixth video clips representing a starting position and an ending position set to an output video signal. The first, second, third and fourth video clips are displayed on the basis of time information attached to each video clip so as to express a positional relationship of the first, second, third and fourth video clips on a time axis. Also, the fifth and sixth video clips are displayed.

Abstract: An alkali resistant synthetic fiber and a sheeting obtained therefrom are disclosed, the fiber being comprised of a polymer mixture consisting of (A) from 15 to 80% by weight of polysulphone, (B) from 20 to 85% by weight of polyvinyl chloride having a degree of polymerization of from 800 to 2,500, and (C) up to 65% by weight of other vinyl polymer, each based on the total weight of the components (A), (B), and (C). The sheeting is excellent in alkali resistant in high temperatures and liquid retention and is therefore useful as industrial filters, battery separators, and industrial wipers.
