It is an object of the present invention to improve the performance of gradient liquid transfer in nano/micro liquid chromatographs when solvents are mixed.In a gradient liquid transfer device and method for a nano/micro liquid chromatograph, an opening and closing unit (160) capable of opening and closing a solvent passage (150) for transferring a secondary solvent is provided in the vicinity of a solvent mixing section (152) in a liquid transfer system (130); a passage from a metering pump (146) of a liquid transfer section (142) to the opening and closing unit (160) is filled with the secondary solvent in advance; and an appropriate pressure is applied to the secondary solvent. Therefore, the entry of a primary solvent into the solvent passage for transferring the secondary solvent is suppressed. In another gradient liquid transfer device and method for a nano/micro liquid chromatograph, a liquid having a low compression rate is filled, in advance, in a part of a solvent passage subsequent to a metering pump of a liquid transfer section, and only the required amount of a secondary solvent is filled subsequent to the liquid. Therefore, the entry of the primary solvent into a solvent passage for transferring the secondary solvent is suppressed, and liquid-transfer performance is improved.

In order to improve filter loss of a waveguide filter having coaxial/waveguide mode conversion parts at its ends, conductor posts bridging a space between two long sides of the waveguide are provided between the parts and the ends. The conductor posts have sufficient thickness and remain close enough to each other and to short ends of the waveguide that a partition plane including axes of the conductor posts can be regarded as an imaginary short plane. The conductor posts are located so that the partition plane is positioned at a distance .lambda./4.times.n (n=1, 3, 5 . . . ) from the coaxial/waveguide mode conversion part.

In a structure adopted for an FM-CW radar, a corner waveguide for connecting each of transmission and reception antennas to a sensor unit is integrated with a sensor unit case. In a waveguide/strip line converter for converting the transmission mode between the waveguide and the strip lines in the circuits of the sensor unit, a ditch is dug in the inner wall of an opening of the waveguide in order to prevent oozing of conductive adhesive. The strip line board is abutted on the inner wall of the waveguide in order to restrict a length of a projecting portion of a line conductor on the strip line board. By employing an oscillator mixer or a multiplier mixer, the circuitry in the sensor unit can be simplified without using lots of expensive millimeter wave devices. Furthermore, power can be utilized effectively even when a switching radar is off, which enables measurement of an absolute speed. Moreover, cost reduction can be achieved.
