Abstract: A method for installing a spray pipe, including an insertion step of inserting a spray pipe from an opening portion, a positioning step of positioning the spray pipe such that an installation surface of a leg portion faces a supporting surface of a supporting portion, a provisional tightening step of provisionally tightening a first fastening portion to couple an attachment flange with the opening portion, an adjusting step of adjusting the height of the installation surface relative to the supporting surface such that an axis along which a pipe portion extends coincides with the horizontal plane, in the provisionally tightened state resulting from the provisional tightening step, a coupling step of coupling the leg portion to the supporting portion by means of a second fastening portion, after the adjusting step, and a final tightening step of performing a final tightening of the first fastening portion after the coupling step.

Abstract: An object is to provide a spray pipe and a desulfurization apparatus provided with the spray pipe that facilitate determination of abrasion of the spray pipe and determination of necessity of repair and replacement of the spray pipe. The spray pipe according to the present disclosure includes: a tubular strength layer that is configured of :fiber-reinforced plastic; an outer abrasion resistant layer that covers an outer peripheral side of the strength layer; and an inner abrasion resistant layer that covers an inner peripheral side of the strength layer. The outer abrasion resistant layer is a laminated body of a plurality of first abrasion resistant layers, and colors of the plurality of first abrasion resistant layers are different from each other.

Abstract: An endoscope apparatus to which an endoscope is detachably connected has an endoscope interface, an image processor and a parameter transfer control section. Here, the endoscope multiplexes a video signal obtained by an image pickup section with an endoscope ID as endoscope identification information, and transmits the signal to the endoscope apparatus. The endoscope interface separates the endoscope ID from the signal from the endoscope. The image processor has a parameter register in which a parameter related to an image process of the video signal is set, and a functional module for performing a predetermined image process with respect to the video signal based on the parameter. The parameter transfer control section reads the parameter corresponding to the endoscope ID separated in the endoscope interface, from a table memory for storing the parameter for each endoscope ID, and transfers the parameter to the parameter register.

Abstract: The gas-liquid contact plate is constructed so that a plurality of straight rows are provided; irregularities are formed over both surfaces of the plate at equal intervals in the row; the adjacent rows have repeated irregularities opposite to each other; and in a peak or valley portion of the irregularities, there is formed an opening connecting the surface to the back surface between the adjacent rows. There is provided a gas-liquid contact plate that has high wettability, being capable of improving the gas-liquid contact efficiency, and is light in weight and advantageous in terms of manufacturing cost.

Abstract: An address fault monitoring device and an ATM switching device capable of efficiently monitoring faults and quickly performing counter-fault process. Data storing unit stores data transmitted thereto. Write control unit controls the writing of data with respect to the data storing unit and notifies a read control side of write address information WD including information on a write address. Read control unit controls the reading of data with respect to the data storing unit and notifies the write control unit of read address information RD including information on a read address. Floating address measuring unit counts the number of floating addresses, and when a transmission error has occurred during transmission of the write address information WD or the read address information RD, it reckons the corresponding write or read address as a floating address.
