Abstract: An operation condition setting support device supporting setting of an operation condition of a plant includes a state value acquirer acquiring state values representing states of controlled devices during operation of the controlled devices, a predictor estimating predicted values for the respective state values at a predetermined future time point based on the respective state values acquired by the state value acquirer, and a notifier, in a case where an index calculated based on a difference between each of the state values at the predetermined time point acquired by the state value acquirer and each of the predicted values at the predetermined time point or a later time point than the predetermined time point estimated by the predictor or a change ratio of the difference satisfies a predetermined condition, providing notification of the case.

Abstract: A cord clamp includes: two plate sections; and a base plate section that connects one end sections of the plate section in the longitudinal direction. A step a surface of which is shifted in a direction intersecting a plane formed by a cord insertion direction in which a cord passes between the plate sections and the longitudinal direction is provided on each of an inside surface formed on the side where the two plate sections face each other and an outside surface formed on an opposite side of the inside surface, a location in the direction where the step of the inside surface is provided and a location in the direction where the step of the outside surface is provided are equal to or greater than a plate thickness of the plate section and equal to or less than three times the plate thickness thereof.

Abstract: A tray unit includes: a plurality of trays each of which has a protrusion at a side end portion thereof; and a pair of frames vertically provided with a plurality tiers of rail portions, the plurality of tiers of rail portions accommodating the plurality of trays in a slidable manner in a horizontal direction. And the rail portion at each tier include a clamp on a surface facing the side end portion of the tray, the clamps in the plurality of tiers are aligned in a vertical direction, the clamp has an opening to which the protrusion is fittable, and when the side end portion of the tray move to a predetermined position with respect to the rail portion, the clamp is elastically deformed in the vertical direction of the rail portion, and the protrusion is fitted into the opening.

Abstract: An optical fiber rack includes a rack part on which a termination unit is located, and an optical fiber housing part for housing an extra length wiring part in an optical fiber bundle, the optical fiber housing part being positioned in a first direction. The termination unit includes a plurality of first optical fibers, a ay provided on one end side of the termination unit in a second direction, the tray being slidable in the second direction, and a plurality of adapters which are arranged in a line on the tray. The tray has a first support part for supporting the optical fiber bundle, the optical fiber rack further includes a second support part arranged in the second direction with respect to the first support part, and the second support part stretchably supports the optical fiber bundle extending from the first support part to the optical fiber housing part.

Abstract: A bracket for attaching an optical unit to a rack is provided. The bracket comprises a bracket body and a fastener. The bracket body has a first wall including a first face and a second face opposite to the first face, and a protrusion extending in a direction intersecting with the first wall from the second face against the first face. The bracket body is provided with a hole penetrating through the first wall from the first face to the second face. The fastener is arranged to pass through the hole on the first wall and is configured to be rotatable with respect to the first wall. The fastener has a first hook including a holding surface substantially parallel to the second face. The holding surface of the first hook faces the second face to define a first gap between the holding surface and the second face of the first wall at least when the fastener rotates from an initial position to a first locking position.

And the rail portion at each tier include a clamp on a surface facing the side end portion of the tray, the clamps in the plurality of tiers are aligned in a vertical direction, the clamp has an opening to which the protrusion is fittable, and when the side end portion of the tray move to a predetermined position with respect to the rail portion, the clamp is elastically deformed in the vertical direction of the rail portion, and the protrusion is fitted into the opening.

Abstract: Each of optical fibers has a core and stress applying members disposed around the core. End portions of the optical fibers are mounted on a fusion-splicing apparatus, and aligned through the image observation from two different lateral directions of the optical fibers. Then, a distance between positions of a bright portion end and a luminance peak closest to the bright portion end is obtained on each bright portion end of a luminance distribution of the optical fiber obtained from at least one picked-up image. The optical fibers are fusion-spliced by aligning the stress applying members so that the sum of the distances is adjusted to be minimum. Alternatively, a distance between positions of the luminance peaks respectively closest to the respective bright portion ends is obtained and the optical fibers are fusion-spliced by aligning the stress applying members so that the distance is adjusted to be maximum.
