A fixing device includes: a fixing member that fixes a toner image onto a recording medium; a pressing member that presses the recording medium against the fixing member; an oiling unit that applies release oil onto a surface of the fixing member to clean the surface; a removing member that is arranged between an downstream side of the oiling unit and an upstream side of the pressing member in a rotating direction of the fixing member and movable between an in-contact state where the removing member is in contact with the surface of the fixing member and an out-of-contact state where the removing member is out of contact with the surface; a drive unit that drives the removing member; and an oiling control unit that, when starting earliest fixing, controls the drive unit to gradually move the removing member from the in-contact state into the out-of-contact state.

A printing system includes first and second printing apparatuses that form images on first and second surfaces of a continuous recording sheet, respectively. The second printing apparatus includes a printing unit that forms a toner image on the sheet; a conveying unit that conveys the sheet at a reference speed in the printing unit; a fixing-conveying unit that conveys the sheet and fixes the toner image adhered to the sheet; a buffer unit that takes up slack in the sheet generated because of a difference in conveyance between the conveying unit and the fixing-conveying unit; a determining unit that determines a brake force for stopping conveyance of the fixing-conveying unit, based on a buffer amount of the buffer unit, which corresponds to the slack in the sheet; and a conveyance control unit that performs control to stop conveyance of the sheet by the determined brake force.

Disclosed is a vinamidinium salt represented by the formula (I): [wherein R1 represents a hydrogen atom, a halogen atom, an optionally substituted hydrocarbon group or the like; R2 and R3 are the same or different and each represents a lower alkyl group, or alternatively R2 and R3 may combine together to form a ring; R4 and R5 are the same or different and each represents a lower alkyl group, or alternatively R4 and R5 may combine together to form a ring; X and Y are the same or different and each represents a bromine atom or a chlorine atom; n represents a number of not less than 2; and m represents 0 or n], which can be used as a general purpose reagent useful for synthesis of various nitrogen-containing heteroaromatic rings having a substituent. The vinamidinium salt has excellent storage stability and reaction selectivity. A method for synthesizing a nitrogen-containing heteroaromatic ring compound using the vinamidinium salt is also disclosed.

A cathodic protection system has electrodes disposed in a coolant passage of an engine filled with a conductive coolant. The electrodes are electrically insulated from the engine. A power supply device provides for a protective electric current to form from the electrodes to the engine through the coolant. The cathodic protection system reduces engine manufacturing and maintenance costs and provides an anticorrosive effect without increasing the size of the engine.

[Problem] Information communication cannot be performed through a system with high-level security installing such as firewall, and it is not possible to construct an information management system which allows seamless access to information from inside/outside of an intranet. [Means to Solve the Problem] A system control apparatus 60 is provided to an intranet 30 for managing groupware information and files. A service site 70 is provided to an Internet 10. A file duplication daemon 63c is provided to each of clients 40 and 41. The file duplication daemon 63c in cooperation with the system control apparatus 60 transfers data of the client 40 to disk resources 50, 61, 71 of the intranet or the Internet as a file. Further, the system control apparatus 60 in cooperation with the service site 70 synchronizes groupware information. Accordingly, seamless access to the information can be accomplished from both inside and outside of the intranet.

Novel pharmaceutical compositions for inhibiting Th2-selective immune response and pharmaceutical compositions for inhibiting cyclooxygenase comprising condensed pyrazole derivatives represented by the general formula (I): or salts thereof.
摘要:
A contact-discharge truing/dressing method and a device therefor, capable of very simply conducting truing/dressing of a superabrasive grindstone, especially a superabrasive grindstone having a metal binder. The contact-discharge truing/dressing method brings a rotated conductive grindstone into contact with a pair of electrodes to which a DC voltage or pulse voltage is applied, and subjecting the conductive grindstone to an intermittent truing/dressing by contact discharge produced when opening/closing a circuit of a positive electrode, electrode chips, a grindstone binder, electrode chips, a negative electrode, and parts of the side surfaces of dual-ring rotary electrodes insulated by an insulation layer being used as a pair of electrodes.
摘要:
In a print position setting method, a sequence of the following operations of printing a toner mark 4 by the obverse side printer, of detecting the toner mark 4 by a mark sensor 9, and feeding a printing sheet a distance ranging from a toner mark detecting position 12 to a page leading edge position 6 when the printing operation starts, is automated.
摘要:
A data storage system in which system activation is performed in cooperation with two host systems sharing a data storage system. A determination unit determines which of the two host systems makes access to the data storage system. A system access control unit controls access to the data storage system from the host systems to prevent competition between the host systems. Each of the host systems indicates completion of system activation to the other host system.
摘要:
A transmission monitoring and controlling apparatus is provided between a first system and a second system. The transmission monitoring and controlling apparatus monitors information transmitted through a Fibre Channel. Then, a back controller analyzes the monitored information and stores the information in a controlling memory based on the analysis. For example, when the first system writes data on the second system, the back controller stores the data in the controlling memory. Therefore, even if a failure has occurred in the second system, the transmission monitoring and controlling apparatus is able to read the data from the controlling memory and send the data to the first system instead of to the second system.
