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.

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.

Abstract: 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 50? microstrip line when the characteristic impedance of the waveguide is about 80%, i.e., 40?, the line conversion loss can be optimized. Therefore, the microstrip line is connected with the waveguide using a ?/4 matching box via a ridged waveguide having a low impedance and a length of ?/16 or less.
