    摘要: The emergency call such as Enhanced 911 call or the like is also originated through an exchange such as PBX (Private Branch Exchange). In this case, the identification information such as the extension number of the extension telephone terminal connected to the PBX should be transmitted to a network corresponding to the emergency call. For the extension telephone terminal, it is necessary to unhook or to capture an arbitrary line by the line key, before inputting the dial data “911”. Independent of the capture of arbitrary line, the PBX searches a vacant line connected to the network corresponding to the emergency call, captures the vacant line, transmits the identification information such as the extension number, and switches over and connects the extension telephone terminal from the line captured by the terminal to the vacant line. The identification information such as the extension number is notified, not by the DTMF (Dual Tone Multi-frequency) signal expressing data corresponding to the number of dial key, but by using a MF (Multi-frequency) signal expressing more data.

    摘要: In an exhaust gas purification device, a catalytic converter containing selective reduction catalysts is disposed in an exhaust gas passage of an internal combustion engine capable of being operated at a lean air-fuel ratio. The catalytic converter includes a plurality of the selective reduction catalysts disposed in series in the casing of the catalytic converter. Bypass passages which supply the exhaust gas to downstream selective reduction catalysts in the casing by bypassing the upstream catalysts are provided. When a reducing agent is supplied to the exhaust gas upstream of the converter, a part of the supplied reducing agent directly reaches the downstream selective reduction catalyst through the bypass passages without being oxidized by the upstream selective reduction catalysts. Therefore, the NOx purifying abilities of the downstream catalysts are improved and the formation of sulfates on the downstream catalysts is suppressed.

    摘要: A photosensor signal processing apparatus is used in combination with an image sensor comprised of a matrix of pixels or photosensors capable of producing an output as a linear function and a logarithmic function of incident illumination. The apparatus includes a correction data storage device which stores therein a set of data about the respective photosensors for the correction of individual outputs of the photosensors, and a correcting device for correcting the respective output values of the photosensors on the basis of the correction data. Thus, even when the individual outputs of the photosensors generate have different characteristics, the output characteristic variation between the photosensors are corrected such that the output characteristics of all the photosensors agree with a reference output characteristic. A fixed pattern noise resulting from the pixel-to-pixel output characteristic variation can be suppressed.
