  • Publication number: 20200366883
    Abstract: A stereo camera accurately measures the parallax of an object in real time and an accurate distance, even in a device in which the vertical positions of two cameras are mutually offset. A left camera starts to capture an image. An image capturing region of a right camera is set to be below that of the left camera, and the start of image capture by the right camera is delayed. Image capture by the right camera starts after a time difference has elapsed. Feature points in images from the left and right cameras are extracted, and feature points in the vicinity of a height set in advance in the left and right images are extracted. Detection is performed to ascertain whether the average value of a left/right difference for a plurality of points is set in advance, and a difference at the current time is calculated.

  • Patent number: 9155978
    Abstract: A very highly concentrated solution is obtained in a single cycle of operation. In the solution separating apparatus, the solution is atomized into the mists to be mixed with the carrier gas, the carrier gas containing such atomized mists is transferred to the collection unit 3, and the collection unit 3 is so constructed and arranged that a specific target substance is separated and collected from the atomized mist component. The solution separating apparatus allows the mist component, by means of the carrier gas, to be in contact with the molecular sieving adsorbent 4 having a molecularly sieving capability of adsorbing the adsorbable component contained in the mist component so as to be separated from the mist component. The non-adsorbable component which is not adsorbed into the molecular sieving adsorbent 4 is separated from the mist component contained in the carrier gas in which the adsorbable component is separated, so that the target substance is separated from the carrier gas.

  • Patent number: 7946508
    Abstract: A method and apparatus for separating a solution containing a target substance. The solution is atomized into a mist in an atomizer (1) to produce a mixed fluid of mist and gas. In the collection of the mist from this mixed fluid, a gas transmission membrane (51) is used. The gas transmission membrane has a pore size that transmits gas but does not transmit the target substance contained in the mist. The mixed fluid is brought into contact with the primary surface of the gas transmission membrane (51), and the pressure on the primary surface is made higher than the pressure on the secondary surface of the opposite side. Thus, the gas in the mixed fluid is allowed to pass through the gas transmission membrane (51) to separate part or all of the gas contained in the mixed fluid.

  • Patent number: 7898347
    Abstract: In the mass production of dielectric resonator oscillators (DROs), it is necessary to regulate the position where a dielectric resonator is placed with a high degree of accuracy and thus time required for the assembly work increases undesirably. Further, a terminating resistor and earthing means are formed at an end of a transmission line that is electromagnetically coupled to the dielectric resonator and constitutes the resonator on a dielectric substrate, and as a result the production cost increases. The present invention is characterized in that, in the components of a DOR, only a transmission line is formed on a dielectric substrate, and an oscillating active element and a terminating resistor and the earthing means on an MMIC chip are connected to the transmission line with metallic wires, metallic ribbons, or the like. Further, an open stub is formed in the middle of the transmission line on the side close to the oscillating active element when it is viewed from the dielectric resonator.
