The present invention relates to a multi-period cycle-alternative switching mode power supply control device and its control method, and the device comprises: a power transfer control unit, a dimming bias control, a burst timing control, and a steering logic; and the method is a power control method that uses a burst timing control to produce an ON_OFF (High_Low) control timing, and after regulated power with a different amplitude is added to the OFF period of the burst period between two ON_OFF periods, two or more mixed periods are used to regulate the timing to a highly reliable and a broad dynamic range. The device of the invention can effectively control certain power transfer components of specific nature and assure that those components and the loading at the rear end can operate more efficiently in a reliable range of a specific nature.

When receiving information to specify a purchase portion of contents that are priced so that a portion whose sales unit price gradually increases from a sales unit price of an initial portion exists, and a purchase instruction from a terminal of a purchaser, information concerning a purchase range of the contents and price information is stored into a storage device so as to correspond to the purchaser, and data for the purchase portion of the contents is transmitted to the purchaser. Thus, following benefits are obtained by carrying out not the simple tally trade, but a tally trade of the contents under the price setting in which the sales unit price gradually increases from the initial portion of the contents, for instance. That is, (a) the purchaser can firstly purchase portions of the contents at a low price, and when he or she judges at an early stage that he or she does not like them, and stops their purchase, the cost can be lowered as a whole, and he or she can tentatively read a lot of books. And, (b) the contents seller can obtain the same sales as the conventional one, when the purchaser buys the entire contents, and even if the purchaser stopped his or her purchase halfway, the contents seller can obtain the sales up to the purchased portions. Furthermore, there is a benefit in which the cost can be suppressed to very lower price than selling goods.
