Abstract: The present invention provides a pickling method of steel sheet and pickling system of steel sheet able to efficiently remove oxide scale from steel sheet. That is, it provides a continuous pickling method of steel sheet having a step A of pickling the steel sheet in a pickling tank, a step B of blowing gas toward at least part of the surfaces of the steel sheet in the air after the step A, and a step C of pickling the steel sheet in a pickling tank after the step B, wherein at step B, the steel sheet is temporarily taken out from the pickling solution and gas is blown to at least part of the surfaces of the steel sheet in the air so as to evaporate the acid solution deposited on the surface of the steel sheet and locally increase the acid concentration to thereby efficiently remove even the stubborn Si oxides included in the oxide scale.

Abstract: Disclosed are: an exhaust gas purification catalyst which is an inexpensive three-way catalyst, which contains a reduced amount of an expensive noble metal, particularly does not use Pt, and contains no expensive rare earth element, and which has the same level of catalytic activity as that of a conventional one; and a catalytic honey-comb structure for exhaust gas purification. Specifically disclosed are: an exhaust gas purification catalyst comprising (?) an oxide M(Co1-yFey)O3-? [wherein M represents a combination of an element substantially selected from Ba and Sr; y represents a number of 0 to 1; and ? represents a value that is so defined as to satisfy the charge neutrality condition] carrying one or two noble metals selected from Pd and Rh and (B) active alumina carrying one or two noble metal selected from Pd and Rh; and a catalytic honey-comb structure for exhaust gas purification, which is produced by wash-coating the exhaust gas purification catalyst onto a ceramic- or metal-made honey-comb.

Abstract: An image reading apparatus includes a roller which transports a sheet, a motor which drives the roller, an image sensor which reads data from the sheet and a control unit which synchronizes a read timing of the image sensor with a drive timing of the motor in response to change in the drive timing of the motor. Accordingly, when transporting an sheet is temporarily stopped, the transport speed can be changed as desired, whereby the shock caused by changing the transport speed is more lightened and if the resolution to read the original is high, a discrepancy in the data read by the image sensor caused by temporary stop of transporting the sheet can be also suppressed.

Abstract: A method for the supply of a constant-concentration ozonated water, employs a unit for producing ozonated water and a system for using the ozonated water at a place separated therefrom, interposing an ozonated water circulating line between the ozonated water producing unit and the place for using the ozonated water, causing the interior of the circulating line to circulate the ozonated water so that the flow rate may be constantly fixed at the outlet of the ozonated water producing unit, monitoring the ozone concentration of the ozonated water in the neighborhood of the outlet, adjusting the amount of an ozone gas supplied to the ozonated water producing unit based on the results of the monitoring, further monitoring the amount of the ozonated water used at the place for using the ozonated water, and controlling the amount of the ozonated water to be produced based on the results of this monitoring.

Abstract: A functional water containing a fluorine-containing component obtained by electrolyzing an aqueous solution containing fluoride ion using electrodes having conductive diamonds, a method of producing the same, and a method and an apparatus of rinsing electronic parts using the functional water as a rinsing water. The fluorine-containing component produced by electrolyzing the fluoride ion using the conductive diamond, has stronger rinsing effect than that of a fluorine-containing component obtained by electrolyzing the fluoride ion itself before electrolysis or the fluoride ion using other electrodes. Therefore, an amount of hydrofluoric acid used can greatly be decreased.

Abstract: A method is provided forwarding ozonated water efficiently with the loss of ozone lowered. The method for forwarding ozonated water is from an ozonated water producing device to a use point separated from the device. This enables the use point to be supplied with ozonated water having a concentration adjusted as aimed at, by adding a diluting water to a raw material ozonated water in the neighborhood of the ozonated water producing device under a condition inhibiting exposure to an ambient air, adjusting the amount of the diluting water to be added thereby giving the ozonated water a target concentration at the use point, and subsequently guiding the ozonated water through a pipe to the use point.

Abstract: To perform a link process between a device or a program which makes a connectionless communication and a device or a program which makes a connection communication, a service system is arranged in between. This process is performed via the service system. With this service system, an operating process which is generated and extinguished at each session is generated on a connectionless communication side, while a communication process which stays resident and maintains a line on a connection communication side, so that the link process is implemented by making a communication between the operating process and the communication process.
