IPC: G03G21/00
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To enable the image forming operation and to prevent the execution of job from being influenced, at speed slower than the normal through, during the time until the completion of repairing by changing/controlling the image forming speed to the speed slower than the normal image forming speed, when a cooling fan is judged in a state of stopping. SOLUTION: This image forming device is provided with the drive motor cooling fan 32, so that the temperature, of a drive motor 25 is not raised beyond a fixed temperature. However, in the case of an unexpected failure occurring on the cooling fan 32, a CPU 22 judges that the normal copying operation can not be performed, based on the output of error detecting means, and performs the copying operation at the prescribed low speed. Moreover, the displaying part 33 transmits that effect to a user. Thus, in the case of detecting that the cooling fan 32 is abnormal, the device transmits that effect to the user, and simultaneously to reduce the image forming speed to the speed hardly affecting the breaking force by the driving motor temperature rising, therefore the image forming operation is performed at the low speed, until the repair is completed by a service man or the like.

SOLUTION: This working can be rapidly carried out as a placing base 30 makes a waling 42 to be arranged orthogonally to a waling 14 by only fitting an attaching part 28 to the waling 14. As to the placing face 30, since the waling 14 and the waling 42 are positioned at the same level when the attaching part 28 is fitted to the waling 24, the soil pressure acting on a sheet pile 12 in the excavating direction which the waling 42 receives is directly supported as an axial force of the waling 14 through a stopper 32. Accordingly, it is not necessary to increase the rigidity of the metal fittings 10 or the waling 14 unnecessarily. Since the waling 42 is supported by the waling 14, a shore strut cylinder 18 for fixing the waling 42 is not required and hence, the working space becoms wide and it makes the working easy.

IPC: A01N31/16
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To efficiently suppress the formation of sulfide in a process for removing sulfide in sludge separated as the withdrawn sludge of a primary sedimentation tank and a post-treatment process of sludge by adding a nitrate to the withdrawn sludge of the primary sedimentation tank in a sewage treatment equipment. SOLUTION: Sulfide is formed by the action of sulfate reducing bacteria under an anaerobic atmosphere like the bottom part of a primary sedimentation tank or a treatment process for the withdrawn sludge of the primary sedimentation tank in a sewage treatment equipment and, when hydrogen sulfide is volatilized into the atmosphere, a malodor problem or a corrosion problem of the equipment is generated. Then, by adding an alkali metal nitrate or an alkaline earth metal nitrate to the withdrawn sludge of the primary sedimentation tank, the formation of sulfide is rapidly suppressed without increasing nitrogen load in the sewage treatment equipment. By adding an anthraquinone compd. along with a nitrate, the suppressing effect on the formation of sulfide can be continued and, as this anthraquinone compd., anthraquinone, anthrahydroquinone and an alkyl substituted compd. or hidride thereof are designated.

Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To detect and properly repair an error occurring to the external storage device even in such a case by giving an identification number to each block of a memory card and handling an address error by using identification numbers. SOLUTION: For example, data divided from the head of a file are stored by blocks having logical addresses '1', '2', and '3' when the file is updated, and identification numbers '6', '4', and '1' are given to the respective blocks '1', '2', and '3'. When the data of the block having the logical address '2' is rewritten, the logical address '2' is assigned to another block, new data are written, and the value '5' obtained by increasing the identification number of the original block by one is set as its identification number. In this stage, the two blocks have the same address, but a final flag is stored in the block having the larger identification number by regarding the data stored in the block as new data and the original block is erased.

IPC: G06T7/00
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To precisely extract a rule by efficiently processing the pattern of various forms included in an optional image. SOLUTION: A rule extracting device takes possible rules among the connected patterns of pixels within an imputed pattern 11 as processing objects to the maximum and adds the number of a line segment constituting the straight line to information on the straight line (P4, P11).
