  • Patent number: 12105033
    Abstract: In a nondestructive inspection of a defect of a welded portion of a pipe or a pipe member, work efficiency of a radiation transmission test is improved by reducing a burden on a worker, and an inspection accuracy is improved. Imaging data is acquired by transmitting radiation through a welded portion of the pipe to be inspected. Processing of associating determination data indicating a result of determining a defect of the welded portion of the pipe to be inspected based on a distribution of a transmission intensity of the radiation obtained from the imaging data with image data showing the distribution of the transmission intensity of the radiation is performed. As a result, through use of the imaging data, image data and determination data associated with the image data can be obtained, and the burden on the worker can be reduced.

  • Patent number: 9748829
    Abstract: A power module including: a power conversion unit including N switching-element pairs; and a control circuit. The control circuit receives N command signals, which correspond respectively to the N switching-element pairs, and a shared enable signal. The control circuit is configured to, when the enable signal is negated, execute all-off control of turning off all of the switching elements constituting the power conversion unit, and when the enable signal is asserted, execute normal control, dead-time addition control, and dead-time compensation control for each of the switching-element pairs per period of a corresponding command signal.

  • Publication number: 20160231733
    Abstract: A program creation device includes a processing unit that displays, on a display device, an edit screen on which respective timing charts of controlled units are arrayed in the vertical direction. Upon reception of a first input for designating an arrangement position of a display object on the timing charts to arrange the display object at the arrangement position, the processing unit displays the display object at the arrangement position designated by the first input on the timing charts. After displaying the display object, the processing unit receives a second input including a designation of a type and an input of a parameter. The processing unit then generates an operation program for executing an operation command of the type designated by the second input, to which the parameter input by the second input is applied, at an execution timing according to the arrangement position designated by the first input.

  • Patent number: 9121772
    Abstract: A temperature data coding unit 100 increases the data resolution in a high temperature range and reduces the data resolution in a low temperature range, and makes the data length of the temperature data a fixed length. When carrying out numerical estimation of the fixed length code value in terms of a 2's complement numerical code value, the temperature data coding unit 100 generates coded data that increases with an increase of the pre-coded temperature data in terms of the 2's complement numerical code value.
