摘要： A SAW resonator includes an IDT electrode formed on a piezoelectric substrate and reflector electrodes disposed on both sides of the IDT electrode. The IDT electrode includes first finger-electrodes, second finger-electrodes and strip-line electrodes. The first and the second finger-electrodes do not overlap with each other but are acoustically coupled together by the strip-line electrodes. This acoustic coupling by the strip-line electrodes eliminates the need for a common bus-bar electrode, so that the loss caused by the resistance of the common bus-bar electrode can be reduced, and the SAW resonator can be downsized.

摘要： A novel method for analyzing a specimen molecule with high accuracy through a simple operation by forming a laminar flow of a specimen molecule containing solution and a complex forming molecule containing solution in a microchannel and measuring the variation of the degree of diffusion of complexes each composed of a specimen molecule and a complex forming molecule in the laminar flow. The complex forming molecule is fluorescent, and the variation of the degree of diffusion of the formed complexes is measured from the distribution of intensity of fluorescence. The degree of diffusion of the formed complexes can be quantitatively determined by comparing it with a calibration curve preliminarily defined.
