    摘要： An adaptive controller for an ESPAR antenna randomly perturbs a bias voltage vector V(n) composed of elements of bias voltage values Vm by a random vector R(n) generated by a random number generator, compares an objective function value J(n) of a cross correlation coefficient for a bias voltage vector V(n) before the perturbation with an objective function value J(n+1) of a cross correlation coefficient for a bias voltage vector V(n+1) after the perturbation, and selects and sets the bias voltage Vm corresponding to that when the cross correlation coefficient increases before and after the perturbation. Then the adaptive controller repeats the random perturbation and setting from the bias voltage of respective varactor diodes. This leads to that it is not necessary to provide a long training sequence signal, and the control process can be executed with learning so that a performance can be improved every iteration for search.

    摘要： There are provided a printing method in which at least approximately hemispherical portion of a spherical object to be printed can be printed by pressing a pad against the portion one time, and which can prevent an image printed on the spherical object to be printed from being elongated or distorted, and a printing pad used for this printing method. The method for printing on the spherical object to be printed comprises the steps of preparing a hollow printing pad having a transfer surface, the printing pad being configured so that when the transfer surface is pushed, the gas in the hollow part is released to the outside of the printing pad; transferring ink or paint in recesses formed on the surface of a printing plate to the transfer surface of the printing pad by applying the ink or paint onto the surface of the printing plate and by pressing the transfer surface of the printing pad against the surface of the printing plate; and transferring the ink or paint, which has been transferred to the transfer surface of the printing pad, to the object to be printed by pressing the transfer surface of the printing pad, to which the ink or paint has been transferred, against the object to be printed until at least the hemispherical portion of the object to be printed is wrapped by the transfer surface of the printing pad.

    摘要： A low-profile antenna structure can control its directivity with great flexibility. Excited elements 11 and 12 are symmetrically arranged on a y-axis, whereas parasitic elements 13 and 14 are symmetrically arranged on an x-axis, with respect to an origin. The excited elements, as well as the parasitic elements, each have an inverted-F antenna structure and are a distance of λ/4 apart from each other. Feed circuits 21 and 22 are respectively connected to and feed signals to the excited elements 11 and 12, such that phases of the signals to be fed are different from each other by a desired degree. Variable reactors 23 and 24 (i) are respectively connected to the parasitic elements 13 and 14, and (ii) in accordance with reactance values thereof, can each change an electrical length of the corresponding one of the parasitic elements.
