    摘要: Disclosed is a gain control circuit which comprises a gain control section including as its essential component a differential amplifier with which diodes or transistors arranged to act as diodes are connected as a load, and a control signal section including a logarithmic compression circuit and an exponential expansion circuit and providing a control signal for control of the gain of the gain control section. A temperature compensation circuit having a temperature dependence cancelling both the temperature dependence of the gain control section and that of the control signal section is provided in the bias circuit for the transistor in the last stage of the control signal section, so that the desired temperature compensation for the entire gain control circuit can be achieved at a single point.

    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.

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.
