摘要:
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.

In the ultrasonic atomization method, a liquid is ultrasonically oscillated in an atomization chamber 4 and a liquid column P is projected in carrier gas to thus atomize the liquid into mists, the carrier gas carrying the atomized mists outwardly of the atomization chamber 4; the carrier gas is forcibly sucked from a lateral point being away at a distance (d1) of 5 cm or less from a center axis m of the liquid column P and thereby a gas flow is blown across the liquid column P; the mists are separated away from the liquid column P by means of the blown gas flow; and such separated mists are transferred outwardly of the atomization chamber 4 by means of the carrier gas.

In a millimeter waveband transceiver using an antenna and a waveguide for a connection line, it is necessary to perform transmission mode line conversion between TEM waves of a microstrip line and VTE01 mode waves of the waveguide. There is a limit to reducing the conversion loss using only a matching box for connecting the microstrip line with the waveguide. In a transmission mode line transducer for converting between the TEM waves of the microstrip line and the VTE01 mode waves of the waveguide, if the cross-sections are substantially the same size, in the case of a 50Ω microstrip line when the characteristic impedance of the waveguide is about 80%, i.e., 40Ω, the line conversion loss can be optimized. Therefore, the microstrip line is connected with the waveguide using a λ/4 matching box via a ridged waveguide having a low impedance and a length of λ/16 or less.

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.

In the present invention, a solution containing a target substance is atomized into a mist by ultrasonic oscillation in an ultrasonic atomization chamber, and the target substance is collected by aggregating the atomized mist in a collection chamber, whereby the target substance is separated from the solution. Further, in the present invention, the gas phase pressure in the collection chamber is maintained to be higher than an atmospheric pressure, whereby the saturation vapor pressure of the target substance in the gas phase is made lower than the saturation vapor pressure under atmospheric pressure.

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

In the present invention, petroleum is separated into hydrocarbon mixtures having different components at an atomizing step and a collecting step. At the atomizing step, the petroleum is ultrasonically vibrated and is discharged and atomized in a state of an atomized fine particle floating in a carrier gas. At this step, the petroleum is separated into a mixed fluid containing the atomized fine particle and the carrier gas and residual petroleum which is not atomized. At the collecting step, the hydrocarbon mixture is separated and collected from the mixed fluid obtained at the collecting step. In the separating method, the petroleum is separated into the residual petroleum and the mixed fluid at the atomizing step, and the mixed fluid is collected at the collecting step so that the petroleum is separated into hydrocarbon mixtures having different components.
