摘要： A radio communication device according to the present invention adaptively controls directivity of a transmission radio signal by using a plurality of element antennas on the basis of a received radio signal received from a communication target counterpart radio communication device. The radio communication device includes a transmission controller configured to process the transmission radio signal according to a first control method for adaptively controlling the directivity, a propagation path state detector configured to detect fluctuation state of a propagation path to a counterpart radio communication device, and a judgment unit configured to judge whether or not to change the directivity on the basis of the fluctuation state of the propagation path. If it is judged that the directivity is to be changed, the transmission controller switches to a second control method that is different from the first control method, and processes the transmission radio signal according to the second control method.

摘要： A control unit and a control method are disclosed. First and second changing units change impedances of two or more first and second components within predetermined first and second ranges, respectively, the first and the second components affecting an output signal. An evaluation function value calculating unit calculates an evaluation function value that is dependent on the impedances of the first and the second components. A gradient vector calculating unit calculates a gradient vector based on the difference between the evaluation function values before and after the impedance change of the second components. Based on the gradient vector, impedance of each of the first components is changed such that the evaluation function value takes a desired value.

摘要： A heat capacity C1 is obtained by conducting two-dimensional thermal analysis simulation to the cross-section of a wiring. Next, based on one-dimensional approximate equation of &thgr;0=(Q0/2) (&lgr;·SC1)−½ along a wiring length direction, a wiring temperature rise &thgr;0 in the void is obtained. In the expression, &thgr;0 is a rise in wiring temperature in the void, Q0 is a thermal quantity of the void in the wiring, &lgr; is a heat conductivity of the wiring and S is a cross-sectional area of the wiring. The heat capacity C1 may be obtained from an expression C1=&lgr;′{(w/t)+(2.80/1.15) (h/t)0.222}. In the expression, W is wiring width, h is wiring thickness, t is substrate film thickness and &lgr;′ is the heat conductivity of the substrate film. By so obtaining, it is possible to shorten analysis time, to save the capacity of a memory and that of a disk for use in calculation, to obtain a simpler analysis model and to facilitate creating a mesh.
