    摘要： A conventional semiconductor device has a problem that, when a vertical PNP transistor as a power semiconductor element is used in a saturation region, a leakage current into a substrate is generated. In a semiconductor device of the present invention, two P type diffusion layers as a collector region are formed around an N type diffusion layer as a base region. One of the P type diffusion layers is formed to have a lower impurity concentration and a narrower diffusion width than the other P type diffusion layer. In this structure, when a vertical PNP transistor is turned on, a region where the former P type diffusion layer is formed mainly serves as a parasite current path. Thus, a parasitic transistor constituted of a substrate, an N type buried layer and a P type buried layer is prevented from turning on, and a leakage current into the substrate is prevented.

    摘要： Electronic watermark information obtained by changing a luminance value of a luminance signal in a video signal and a copy generation management signal (CGMS signal) inserted into an area out of a scan region of the video signal are recorded into a recording medium. A reproducing apparatus comprises an electronic watermark information detecting circuit, a CGMS signal detecting circuit, a control circuit to which detected electronic watermark information and CGMS signal are supplied, and a video signal processing circuit controlled by an output of the control circuit. When the electronic watermark information and the CGMS signal have a rational relation, the video signal processing circuit is controlled to output the video signal.

    摘要： An antibody reacting specifically with human LECT2. This antibody is produced by hybridoma clones G2A5D7 (Accession No. FERM P-15638), A1G1C6 (Accession No. FERM P-15639), 5C5 (Accession No. FERM P-15640), H12D10D6 (Accession No. FERM P-15641), etc. Human LECT2 can be assayed by reacting human LECT2 successively with an immobilized antibody which has been formed by binding the above-mentioned antibody to an insoluble support and a labeled antibody which has been formed by labeling another antibody reacting with human LECT2 with a labeling agent, and then determining the amount of label in the reaction product.

    摘要： A semiconductor device enables a semiconductor element to turn off accurately and quickly at the time of short circuit of the load to protect the semiconductor element from the short circuit of the load. The semiconductor device comprises a first switching measure for turning on/off a current flowing into the load, a current detector for detecting current flowing into the load, a second switching measure for turning on/off a connection between the current detector and the load, and a controller for controlling the first switching measure and the second switching measure. The controller turns on the first switching measure, before turning on the second switching measure at the start of driving of the load. The current detector turns off the first switching measure when detecting excess current.
