摘要:
A repairing method using a lance for repairing an oven wall surface of a coke oven comprises the steps of arranging a distance sensor at a top end of the lance, quantitatively measuring a depth of a worn or a damaged area by the distance sensor, and blowing a repairing material from a repairing nozzle to the worn area in accordance with a measurement result to thereby repair the worn area. The lance used in this repairing method has a multistage structure having a polygonal cross section and is extendable. With this structure, the oven wall surface can be scanned in a linear fashion or along a plane. If the top end of the lance is movable in accordance with a basic motion pattern and/or a travelling pattern, it is possible to readily repair a repair range having a complicated shape.

An X-ray computed tomography apparatus for providing information of alignment, comprises an X-ray generator, an X-ray detector, and a controller. The X-ray generator generates an X-ray. The X-ray detector comprises a plurality of detecting segments in a slice direction and detects the X-ray generated by the X-ray generator. The controller provides the information of alignment between the X-ray generator and the X-ray detector in the slice direction on the basis of a detection information obtained from at least two of the detecting segments, wherein each of the at least two of the detecting segments is at least partially covered by a penumbra of the X-ray.

According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, a first DAS, and a second DAS. The radiation detector includes a plurality of detection elements. Each detection element repeatedly detects X-rays generated by the X-ray tube and transmitted through a subject and repeatedly generates an electrical signal corresponding to the energy of the repeatedly detected X-rays. The first DAS acquires the electrical signal detected by part of the imaging region of each detection element in the integral mode. The second DAS acquires the electrical signal detected by the other part of the imaging region of each detection element in the photon count type mode.

An X-ray CT apparatus according to the embodiments has a rotation base that includes a plurality of units, including an X-ray generator that irradiates a subject with X-rays, and an X-ray detector that detects X-rays transmitted through the subject. It also has a pathway that communicates between the X-ray detector and at least one other unit excluding the X-ray generator and the X-ray detector. It also has an air supplier that supplies air in the other units to the X-ray detector via the pathway. It also has a temperature measuring part that measures the temperature in the X-ray detector. It also has a controller that performs control of the air supplier based on the measured result from the temperature measuring part.
