  • Patent number: 10986014
    Abstract: A monitoring system detects a deviation in a monitoring metric of a system component of a remote management system that remotely manages image forming apparatuses. When the monitoring system detects a deviation in online device count greater than or equal to a deviation threshold and makes a determination that there is a correlation between the deviations in monitoring metrics of multiple system components as detected, the monitoring system sends a failure report indicating that a failure is in the remote management system.

  • Patent number: 10315263
    Abstract: In a wire electric discharge machine of the present invention, a control variable detection apparatus is an inter-pole voltage detection apparatus and detects an average inter-pole voltage as a control variable correlating with an inter-pole distance. The wire electric discharge machine comprises a machining feed speed calculation apparatus determining a machining feed speed on the basis of a deviation between target voltage set by a target value setting apparatus 7 and the average inter-pole voltage so as to eliminate the deviation. The wire electric discharge machine further comprises a feed speed distribution apparatus and a relative movement apparatus. The inter-pole distance can be kept constant by the relative movement of a wire electrode and a workpiece made on the basis of a command of thus determined machining feed speed.
