Abstract: A numerical controller is equipped with an access unit configured to access variables included within a machining program at a time of analyzing the machining program, a look-ahead determining unit configured to determine whether or not the variables accessed by the access unit were accessed during look-ahead of the machining program, a specific variable determining unit configured to determine whether or not the variables determined to have been accessed during look-ahead by the look-ahead determining unit are specific variables, and an output unit configured to output at least one of numbers of the specific variables accessed during look-ahead and a time of accessing the specific variables during look-ahead, in the event that the variables accessed during look-ahead are determined to be the specific variables by the specific variable determining unit.

Abstract: A numerical control device that suspends tasks related to a machining process when designated conditions are satisfied to execute a designated program as an interrupt. A numerical control device includes: a task management unit that manages tasks that execute a machining program and tasks executed on the background of the tasks that execute the machining program; an interrupt notification unit that monitors system data set to an interrupt condition designated in advance and outputs an interrupt command upon detecting that the interrupt condition is satisfied; and an interrupt processing unit that suspends the tasks being executed at a time point when the interrupt command was received to execute a predetermined interrupt program as an interrupt on the basis of the interrupt command output by the interrupt notification unit.

Abstract: Provided is a numerical controller capable of shortening cycle time while maintaining machining accuracy of a rigid tap. The numerical controller includes: a rigid tap control unit that executes a rigid tap by synchronizing rotational speed of a spindle with feedrate; a synchronization error monitoring unit that starts or terminates monitoring of a synchronization error between the rotational speed of the spindle and the feedrate at a point R set to a height equal to or higher than a top of a workpiece; and a workpiece top detection unit that detects a position of the workpiece top. The synchronization error monitoring unit starts monitoring the synchronization error at the position of the workpiece top instead of the point R.

Abstract: A washing machine includes a wash tub, a water-supply mechanism for supplying water into the wash tub, and a disposition section in which a solid antimicrobial agent containing an organic compound having a nitrogen-halogen atomic combination is disposed. The disposition section is provided in the water-supply mechanism. The antimicrobial agent is brought into contact with water thereby to release hypohalogenous acid into the water.

Abstract: In an image information reading apparatus according to the present invention, a scanner for reading an image is driven along the surface of a desired image sheet to scan the same, by means of a drive unit, in a manner such that the scanner is opposed to the sheet. The scanner is composed of a fluorescent lamp for applying a light beam to the sheet and a photoelectric converter for reading the light reflected from the sheet, and is housed in a case having a transparent cover which faces the image sheet. The fluorescent lamp, which is housed in the case, cannot be influenced by a temperature change outside the case, so that it can expose the sheet surface with a uniform illuminance.
