  • Patent number: 10376831
    Abstract: Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.

  • Patent number: 7525479
    Abstract: An array antenna includes a first end portion that has a first plurality of antennas arranged with a spacing d therebetween and a second end portion that has a second plurality of antennas arranged with the spacing d therebetween. In the array antenna, a spacing between respective antennas in both the first and second end portions and are closest to a central portion is set to 2d, which is a value obtained from multiplying 2, which is the number of the antennas constituting each of both end portions, by the spacing d for both end portions. The antennas in the antenna array are continuously selected as a transmitting antenna by switching, and continuously emit transmission signals. The antennas in the antenna array are also successively selected as a receiving antenna by switching. In this way, by switching between transmission and reception of the antennas of the antenna array, nine reception channels CH1 through CH9 that are arranged with a uniform phase difference therebetween are obtained.

  • Patent number: 7355560
    Abstract: A design process first determines a desired aperture distribution, then converts the electric power conservation law, Snell's law on the rear face side of a dielectric lens, and the formula representing light-path-length constraint, into simultaneous equations, and computes the shapes of the surface and rear face of the dielectric lens depending on the azimuthal angle ? of a primary ray from the focal point of the dielectric lens to the rear face of the dielectric lens, and then reduces the light path length in the formula showing light-path-length constraint by an integral multiple of the wavelength when the coordinates on the surface of the dielectric lens reach a predetermined restriction thickness position. A dielectric lens is designed by sequentially changing the lazimuthal angle ? from its initial value, and also repeating the second and third steps.
