    摘要： In an endoscopic system, when an affected area of a biomedical tissue in an image is treated with a scalpel and a holding pair of forceps which movably extend from a distal portion of an endoscope through the endoscope while the image taken by the endoscope in a body cavity in a time-series manner is being observed, a treatment is performed in which the holding pair of forceps holds the affected area detached from the biomedical tissue by the scalpel. When any motion is detected in the distal portion of the endoscope included in the image, a motion direction and a motion amount of the distal portion of the endoscope attributed to the motion are detected, and the distal portion of the endoscope is curved to return the scalpel to an original treatment position.

    摘要： A fuel supply apparatus includes a movable unit, a coil, a drive circuit portion, and a drive control portion. The drive circuit portion energizes the coil with a drive electric current of a first value such that the movable unit is displaced from an opening-side position to a closing-side position. The drive circuit portion energizes the coil with the drive electric current of a second value that is smaller than the first value such that the movable unit is held at the closing-side position. The drive control portion controls the drive circuit portion to change the drive electric current from the first value to the second value while the movable unit is being displaced toward the closing-side position based on energization of the coil with the drive electric current of the first value.
