摘要： A radio-frequency coil has a first element and a second element both being adjacently arranged so as to nip a division/join portion. The first element has a first main loop portion provided along an arrangement plain surface and a first sub-loop portion provided along a surface substantially perpendicular to the arrangement plain surface. The second element has a second main loop portion provided along the arrangement plain surface and a second sub-loop portion provided facing the first sub-loop. The first sub-loop portion and the second sub-loop portion generate an induced electromotive force such that, among magnetic fields generated when a current flows in one coil, a summation of the magnetic fields, which interlink with the other coil, becomes zero.

摘要： A separation preventive pipe joint is provided, in which a locking ring is held by an elastic ring with its axis centered in a locking ring receiving groove. An outer peripheral projection is formed on an end portion of the spigot, the outer peripheral projection being engageable with the locking ring from a location deeper than the locking ring. An inner peripheral projection is formed in an inner peripheral portion of the socket which is located deeper than the locking ring receiving groove for backing up the locking ring. A first inner peripheral surface having a larger diameter than the inner peripheral projection is formed in an inner peripheral portion of the socket which is located deeper than the inner peripheral projection. A second inner peripheral surface is formed between the first inner peripheral surface and the inner peripheral projection, the second inner peripheral surface being larger than the inner peripheral projection and smaller than the first inner peripheral surface in diameter.

摘要： An image forming apparatus configures a normal transfer potential in a yellow primary transfer unit, and configures a transfer potential which does not cause any retransfer phenomenon of a yellow measurement image in image carriers located on the downstream side of the yellow primary transfer unit. When a color difference obtained from a reference density and a density of a measurement image on an intermediate transfer belt becomes equal to or larger than a prescribed value, the image forming apparatus determines that multinary-color density adjustment is required.
