Abstract: According to an exemplary embodiment, an industrial machine includes: a movement mechanism configured to move along a specific axis direction; a controller configured to control the movement mechanism; and an angle detector configured to detect an angle of the movement mechanism about an axis perpendicular to the specific axis direction. The controller comprises: an angular error acquisition section configured to acquire angular errors of the movement mechanism for respective positions of the movement mechanism based on the angle detected when the movement mechanism is moved; a parameter generator configured to generate respective straightness correction parameters for correcting straightness errors of the movement mechanism in the specific axis direction by integrating the angular errors at the respective positions of the movement mechanism; and a correction section configured to correct movement errors of the movement mechanism based on the straightness correction parameters.

Abstract: A supporting device (300) for supporting a guide rail (200) for guiding a movable member subjected to relative displacement in relation to the base table (3). The supporting device includes, base bodies (410, 510) engaged onto the base table (3) and carrying the guide rail (200), and holding section (440, 530) for holding the guide rail (200) intervening between the guide rail (200) in the state where the guide rail is carried by the base bodies (410, 510). The holding section (440, 530) supports the guide rail (200) in the state where it can move swingingly. A change in the posture or position of the base bodies (410, 510) is offset with a swinging movement by the holding section, and does not affect the guide rail. As a result, excessive force is not applied on the guide rail, so that the form of the guide rail is maintained.

Abstract: A measuring machine having a base (10), a touch signal probe (P), a moving mechanism (20) for retaining the touch signal probe (P) movably in three-dimensional directions, and a controller (60) for controlling a movement of the moving mechanism (20) and for acquiring coordinates value of respective axes based on a contact signal from the touch signal probe (P) to measure a dimension etc. of a workpiece based on the coordinates value is provided. Main structural members structuring the moving mechanism (20), more specifically, a column (21), a supporter (22), a X-beam (23), a Z-axis structure (25) and a Z-axis spindle (26) are made of aluminum or aluminum alloy including aluminum as main component, which has large thermal conductivity, thereby making temperature distribution uniform to improve geometrical accuracy.

Abstract: To securely clean dirty material deposited on ends of board electrical-test probes used in a board test device for executing tests including an incircuit test by a cleaning job executed once, the extreme ends of the contact pins of the board electrical-test probes are pierced through an elastic sheet molded by dispersing fine metal oxide particles dispersed therein in a specific weight percentage amount and then pulled out from the elastic sheet.

Abstract: A connecting apparatus includes a connecting conductor for connecting a supporting insulator supporting an overhead transmission line and a lightning arrester through a disconnecting member. The connecting conductor includes at least first and second conductor segments having given lengths. The first conductor segment connected to the lightning arrester is greater in bending strength than the second conductor segment connected to the disconnecting member.

Abstract: An on-load tap-changing transformer in which its high-voltage winding is axially divided into parallel-connected halves, and an end conductor constituting part of the high-voltage winding is connected to the other terminal of each of the halves. A coarse tap coil connected by the end conductor to the other terminal of each of the halves of the high-voltage winding is disposed adjacent to the associated half, and a fine tap coil connected to the coarse tap coil through a coarse tap selector used for the change-over of the tap position to the taps of the coarse tap coil is disposed at a radial position spaced apart from the coarse tap coil. The end conductor is wound together with the conductors of the fine tap coil.
