Abstract: For preventing holes from occurrence at an internally widened area of a rib knitted fabric, at the area, two needles, one on the front needle bed, the other on the back needle bed, are made empty. Then, a stitch held by an adjacent needle to one of the two empty needles is transferred to the other of the two empty needles so that two continuous needles on one needle bed are made empty and that the former empty needle on the other needle bed is provided with the transferred stitch. A yarn feeder is made to move over the area while feeding yarn till one needle before the two empty needles, then back above the area while feeding the two empty needles and an intermediate opposing bed needle, and move over the area while feeding yarn from the subsequent needles after the two former empty needles.

Abstract: An X-ray generating apparatus in which X-rays are emitted from laser plasma, the X-ray generating apparatus including a strong magnetic field generating device for generating a magnetic field component substantially parallel with the target surface in the vicinity of the laser plasma. The magnetic field component is arranged to generate a magnetic force which acts directly on charged particles in the laser plasma to bend the tracks of the charged particles, causing the charged particles to be confined in a magnetic field formed by the magnetic field component. The magnetic flux of the strong magnetic field is directed to a direction which is different from the direction in which the laser plasma is generated. An X-ray supply object is disposed in the laser plasma generating direction. Charged particles, liable to be directed to the X-ray supply object, are mainly confined in the strong magnetic field.

Abstract: An apparatus and method to separate and store ions by exploiting mobility characteristics of the ions. A sample is introduced into a trap volume and ionized. The ions are separated according to their mobility characteristics by applying an electric field to the trap volume. The ions thus migrate to equilibrium positions in the trap volume due to a difference in mobilities and to changes in the electric field. The ions may be sequentially scanned from the trap by changing the electric field. The identity of ions within the trap may then be determined.
