Abstract: A conductive roll having at least one conductive elastic layer on the outer periphery of a core bar, the conductive elastic layer being granted conductivity by carbon black, is provided. The conductive elastic layer is prepared by reacting at least a polyol consisting essentially of a polyether-based polyol with a diisocyanate with the use of a tetravalent organotin-based compound having a tin content of 18.7% or less by weight as a catalyst. A method for producing the conductive roll is also provided.

Abstract: A conductive roller which can form images of consistent quality and does not cause image failures such as formation of blank spots and a method for inspecting the roller. The conductive roller having a metallic core and at least one rubber elastic layer provided on the outer peripheral surface of the core, the rubber elastic layer being formed from a conductive rubber to which conductivity has been imparted by carbon powder, wherein the conductive roller satisfies the relationship represented by formula (1): Zr/Zc?5??(1), wherein Zr (?) represents a resistance component and Zc (?) represents a capacitive reactance component, the resistance component Zr (?) and the capacitive reactance component Zc (?) being calculated respectively from impedance Z (?) and phase difference ?, when the impedance Z (?) is measured upon application of an AC voltage of 0.2 V at a frequency of 1 Hz to the rubber elastic layer.

Abstract: A monitoring device monitors a packet transmitted to a communication device that is a target of the denial-of-service attack, and detects traffic abnormality information indicating an abnormality of traffic due to the packet with respect to the communication device. A performance measuring device measures performance of the communication device, and detects performance abnormality information indicating an abnormality of throughput of the communication device. An attack determining device determines whether the communication device received the denial-of-service attack, based on the traffic abnormality information and the performance abnormality information.

Abstract: Ink for ink-jet dyeing purposes contains a disperse dye which is insoluble, or slightly soluble, in water, and a dispersing agent which can be represented by the following general formula (I).M--(--OCH.sub.2 CH.sub.2 --).sub.n --X--(--CH.sub.2 CH.sub.2 O--).sub.n --MHere, X in this formula represents --A-- or --O--A--O-- (where A is represented by the formulae indicated below), and M is a hydrogen atom, --SO.sub.3 H, --SO.sub.3 NH.sub.4 or --SO.sub.3 Na, and n is an integer of value 5-20. ##STR1## According to the above ink, there is no blockage of the orifices by the ink and the ink can be discharged from the orifices in the form of very fine liquid droplets which are stable, and mixing of the inks which have be discharged on the surface of the said cloth proceeds smoothly, thereby enabling to obtain uniform and distinct images with no physical defects or color defects.Another aspect is directed to a method of forming mixing color on a material to be dyed.

Abstract: A tool for applying liquids has a nozzle portion which is provided with a spatulate section having a discharge orifice in the side thereof from which the liquid emerges. The spatulate section is mounted on a tool body which is freely rotatable, so that the liquid may be applied to the surface of a tubular object in a convenient manner.
