Abstract: 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.

Abstract: Provided is a lubricant guiding structure in an automatic transmission in which a baffle plate configured to regulate the movement of a lubricant agitated by a driven sprocket is provided at one side, where an oil pump is located, in the direction of a rotational axis of the driven sprocket. As viewed from the rotational axis direction, a division wall disposed to extend across a chain is provided closer to the chain than a base of the baffle plate. As viewed from the rotational axis direction, the baffle plate is provided with a guide wall extending along a torque transmission-side chain of the chain wound on the driven sprocket. As viewed from the rotational axis-direction, the guide wall includes an inclined portion inclined in the direction coming closer to the chain as the distance to the distal end side decreases.
