In an apparatus for carrying out a linear transform calculation on a product signal produced by multiplying a predetermined transform window function and an apparatus input signal, an FFT part carries out fast Fourier transform on a processed signal produced by processing the product signal in a first processing part. A first and a second antenna are disposed within the enclosure. The lightning portion can emits light having a predetermined wavelength depending on the color tone of the pixel portion which is detected by the second optical sensor. The pair of reed switches 13 and 14 are connected to a common wiring 11. A cancellation of the concurrent worker objects is requested by calling the cancel method with the manager object. The reduced-EI portion exhibits a respective rate of stiffness reduction as a function of distance toward the tip-end.
