    摘要： A method and apparatus is disclosed for pattern analysis by arranging given data so that highdimensional data can be more effectively analyzed. The method allows arrangements of given data so that patterns can be discovered within the data. By utilizing maps that characterizes the data and the type or the set it belongs to, the method produces many data items from relatively few input data items, thereby making it possible to apply statistical and other conventional data analysis methods. In the method, a set of maps from the data or part of the data is determined. Then, new maps are generated by combining existing maps or applying certain transformations on the maps. Next, the results of applying the maps to the data are examined for patterns. Optionally, certain strong patterns are chosen, idealized, and propagated backwards to find a data reflecting that pattern.

    摘要： A diffraction grating of the present invention includes a first block (101) and a second block (102). The first block (101) is made up of a plurality of input waveguides (103), a slab waveguide (104), a delay waveguide array (105) and narrow grooves (106): each of which being filled with resin. The second block (102) is made up of a plurality of input waveguides (107), a slab waveguide (108) and a plurality of output waveguides (109). Since a circuit is cut off at the ends of the arrayed waveguides, a relative phase can easily be measured. The resin has undergone a refractive-index adjustment and compensates a phase error.

    摘要： A waveguide type optical branching device having: two input ports; two output ports; optical waveguides extending from the input ports and the output ports respectively; and a coupling portion formed allowing the optical waveguides from the input ports and the output ports to gradually approach each other in a direction toward the output ports. The device is operable such that, in a direction from the input ports to an output end of the coupling portion, when light is inputted to one input port of the two input ports, an even more is predominantly excited, and when light is inputted to the other input port of the two input ports, an odd mode is predominantly excited. The optical waveguides in the coupling portion have a core width that is larger at a middle position in a height direction thereof than at an upper surface of the core.

    摘要： The present invention provides the stress detection method for force sensor device with multiple axis sensor device and force sensor device employing this method, whose installation angle is arbitrary. The stress detection method includes, first and second force sensors whose detection axes are orthogonal to each other. When the detection axis of first force sensor forms angle θ with direction of detected stress Ax, and the stress component of direction perpendicular to direction of the detected stress Ax is Az, output Apx of the axis direction of first force sensor is found as Apx=αx (Ax×cos θ+Az×sin θ), and output Apz of the axis direction of the second force sensor is found as Apz=αz (Ax×sin θ+Az×cos θ), and, when αx and αz are detection sensitivity coefficients of first and second force sensors respectively, the detection sensitivity coefficient αz of second force sensor is set as αz=αx tan θ, and the detected stress Ax is found as Ax=(Apx−Apz)/αx(cos θ−tan θ×sin θ).
