Abstract: A display device includes: a sheet attached to a display panel and a display surface side of a housing; an opening formed on the display surface side of the housing so as to allow access to an interface terminal provided in the housing; and a lid covering the opening. The display panel and the display surface side of the housing are sectioned into a first region to which the sheet is attached and a second region with no sheet attached, with respect to a longitudinal direction of the display panel. The first region is an area including the display panel and part of the housing. The opening is arranged in the second region.

Abstract: A numerical control device includes a CPU for outputting a position command value of a servomotor; an IC including a servo controller for outputting a current command value to an amplifier for driving the servomotor, and an I/O unit for inputting and outputting an external signal; a DSP for reading the position command value and performing control so as to move the servomotor to a position indicated by the position command value; and an inter-device communication path between the CPU and the IC. The IC includes an internal bus connected to a communication interface connected to the inter-device communication path, and the I/O unit; and an internal communication path for directly transmitting a signal between the servo controller and the I/O unit without passing through the internal bus.

Abstract: From an error information containing a content of a correctable error that has occurred in a controller of a failure prediction system and an ID of the controller and manufacturing information of a machine to which the controller is attached, a failure of a controller belonging to a group of controllers in which such an error as indicated in the error information has not occurred yet is predicted.

Abstract: An electronic device including a printed circuit board has a degradation detection circuit that detects degradation of the printed circuit board at a plurality of different degradation levels, and a warning output unit that outputs a warning in accordance with the degradation level detected by the degradation detection circuit.

Abstract: In a control system, a controller and a plurality of input/output units are daisy-chained, and each of the input/output units detects a phase difference between a phase of received serial data and a phase of a reference clock, outputs a determination signal if the phase difference exceeds a threshold value, and records the output frequency of the determination signals. The controller acquires the frequency of the determination signals recorded by each of the input/output unit and specifies a noise mixture route based on the acquired frequency of the determination signals.
