Biological outcomes are detected andor predicted by analyzing biological data containing R-R intervals. In the method, signals are extracted by using K beam forming parts, wherein K is a natural number equal to or more than 2, and received signals from a plurality of antennas are applied to each beam forming part. Height-adjusting device 1 consists of a rotary wheel 8, a socket 9 and a foot 11. Means of modification of the membrane include chemical or physical modification, leading to changes in permeability. A top surface of the gate electrode and a top surface of the first interlayer insulating film are formed in a recessed manner in the trench relative to the surface of the semiconductor substrate, and a surface portion of the semiconductor substrate for the trench is formed into a tapered shape. In order to achieve the object of this invention, a polarization mode convertor converts the TE mode in a waveguide to the TM mode and the TM mode to the TE mode.
