An object of the present invention is to provide a thermal transfer sheet provided with a black dye layer which can form a black image having jet-black color tone, small gradation difference of black and high resistance to light, and which has little offset of dyes to a back side layer during storage in a wound state. The demodulation procedure includes multiplying the received multi-carrier modulated signal with its complex conjugate to obtain a squared signal; multiplying the squared signal with a carrier demodulating signal to obtain a product signal, and integrating the product signal over the duration T. Upon detection of the drive, the game console receives the encrypted certificate and decrypts it. The sound source LSI which possesses a built-in ADPCM function is configured to vocally output a depressed numeric key by using a registered vocabulary. Such methods can also be utilized in a variety of therapeutic applications that involve the regulation of endothelial cell growth.
