  • Publication number: 20190293873
    Abstract: There is provided an optical axis alignment mechanism between the laser oscillator and the optical fiber. The laser oscillator emits laser light, which then emerges from the emission end of the optical fiber via the axis alignment mechanism. Part of the laser light is received on the light-receiving surface of the CCD camera of a laser light evaluator. Thus, the laser light evaluator acquires a light intensity distribution. The light intensity distribution is used by the optical axis alignment mechanism to align the axis of the laser oscillator with the axis of the optical fiber.

  • Publication number: 20180279832
    Abstract: A heating/stirring cooker includes a stirring body. The stirring body is detachably attached to the interior of a container, and stirs the food. The stirring body includes a blade, a permanent magnet, a magnetic metal plate, a storage, and a clutch. The blade stirs the food. When the stirring body is attached to the container, the permanent magnet is located opposite the inner bottom surface of the container and receives a rotating magnetic field. The magnetic metal plate is provided on the permanent magnet and inhibits magnetic flux leakage. The storage has a perimeter on which the blade is formed, and movably stores the permanent magnet. The clutch transmits the rotational force of the rotating magnetic field to the storage, only when a claw is in engagement with a notch. The stirring body generates high rotational force when attached and suppresses the impact of the magnetic field when detached.

  • Publication number: 20180193798
    Abstract: A gas treatment system includes an absorber, a liquid separator, a regenerator, a circulation mechanism and a heat transfer apparatus. The absorber contacts the gas with the treatment liquid. The liquid separator separates the treatment liquid having been in contact with the gas into a first phase portion having a high content of the acidic compound and a second phase portion having a low content of the acidic compound. The regenerator heats the first phase portion to eliminate the acidic compound from the first phase portion. The circulation mechanism recycles the second phase portion and the treatment liquid from which the acidic compound has been eliminated by the regenerator, in the absorber as a treatment liquid with which the gas is to be contacted. The heat transfer apparatus transfers heat from the treatment liquid discharged by the absorber and from the gas having undergone separation of the acidic compound, to the treatment liquid in the regenerator.
