  • Patent number: 6887430
    Abstract: A total reflection cell has a total reflection prism on at least one surface thereof. A mixed solution containing a gold colloid labelled antibody which is adsorbed on a gold colloid is stored in the total reflection cell, and a sample solution containing an antigen causing antigen-antibody reaction with the antibody is added thereto for forming a gold colloid labelled immune complex. A measuring beam is introduced into the total reflection prism from an incident optical system at an angle ? of incidence causing total reflection and an outgoing beam from the total reflection prism is received by a measuring optical system, thereby measuring absorption by the gold colloid labelled immune complex and carrying out qualification and determination of the antigen.

  • Patent number: 6176105
    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.

  • Patent number: 6157701
    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.

  • Patent number: 6124592
    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.

  • Patent number: 6114668
    Abstract: A heater-installed grip for a vehicle includes substantially semi-cylindrical inner pieces (33.sub.1, 33.sub.2) of a synthetic resin which have a planar heater (34.sub.L, 34.sub.R ; 174.sub.L, 174.sub.R ; 184) wound around an outer periphery thereof and which are integrally embedded in a cylindrical grip body (35) made of a rubber assembled to a pipe-shaped steering handlebar (26) or a throttle pipe (79). In this heater-installed grip, a circumferentially central portion of each of the inner pieces (33.sub.1, 33.sub.2) is formed at a large wall thickness, as compared with circumferentially opposite ends thereof. Thus, the assemblability of the grip body (35) to the pipe-shaped steering handlebar (26) or the throttle pipe (79) is enhanced, while ensuring a die-clamping strength in a process for forming the grip body (35).
