    摘要： An exhaust manifold integrally cast with a turbine housing for a turbocharger has pipe portions having exhaust gas flow paths and a plurality of ports adapted to receive an exhaust gas; flanges respectively extending from the ports; a converged portion connected to the pipe portions and adapted to converge the exhaust gas flow paths in the pipe portions; and a turbine housing integrally connected to the converged portion and having a circular exhaust gas flow path therein. The exhaust gas flow path in the converged portion is in a tangent direction relative to the circular exhaust gas flow path in the turbine housing. A neck portion that connects an outer surface of the turbine housing to an outer surface of the converged portion at a particular angle has a radius of curvature that is relative to the distance in a tangent direction of the exhaust gas flow path from the center of the turbine housing to the converged portion. Namely, the ratio of the radius of the curvature to the distance in the tangent direction of the exhaust gas flow path from the center of the turbine housing to the converged portion is 0.13 or more.

    摘要： A frequency synthesizer having reduced spurious components for use in a receiving and transmitting apparatus. The frequency synthesizer includes a direct digital synthesizer (DDS) for generating a first signal having a first frequency determined by channel setting data. The first signal is applied to a frequency divider to generate a divided signal having a divided frequency. The divided signal is applied to a frequency converter for shifting the divided frequency by a shift frequency interval to provide a reference signal having a reference frequency. The reference signal is applied to a phase locked loop (PLL) for generating a final signal having a predetermined frequency characteristic.

    摘要： In a vapor phase apparatus such as a plasma chemical vapor deposition (CVD) having a pair of electrodes, a surface of one of the electrodes has an uneven shape (concave portion and convex portion). An interval between the electrodes is 10 mm or less. A density of a convex portion is increased in a center portion of the electrode. An aspect ratio of the uneven shape is increased from a peripheral portion of the electrode to a center portion of the electrode. The aspect ratio represents a ratio (b/a) of a pitch (a) and a height (b) of the convex portion.

    摘要： When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.

    摘要： In a plasma processing apparatus including a cylindrical electrode and plural electrodes which are disposed to face the cylindrical electrode in a circumferential direction of the cylindrical electrode, the plural electrodes are designed to have the prescribed curvature corresponding to that of the surface of the cylindrical electrode. The interval between the cylindrical electrode and the plural electrodes may be fixed or stepwise varied in the circumferential direction. The area of each of the plural electrodes may be different from that of the other electrodes.
