Abstract: The object of the present invention to reduce the number of X-ray tubes constituting the distributed X-ray source. Disclosed herein is a control method for an X-ray imaging apparatus provided with a plurality of X-ray tubes arranged at fixed relative positions. The control method includes a driving step S1 of sequentially driving the plurality of X-ray tubes, and a movement step S3 of moving the plurality of X-ray tubes. The driving step S1 is executed again after execution of the movement step S3.

Abstract: A driver guide for use with a fastener-driving tool has a first guide member mounted to the tool body of the fastener-driving tool. A mount device is coupled to the first guide member and serves to mount a second guide member to the first guide member. A fastener guide channel is defined between the first guide member and the second guide member. The mount device is operable in at least three different modes including a first, second, and third mode, while the mount device remains coupled to the first guide member. In the first mode, the second guide member can be fixed in position relative to the first guide member. In the second mode, the second guide member is movable relative to the first guide member within a limited range. In the third mode, the second guide member can be removed from the first guide member.
