Abstract: A communication equipment connection adapter 1 for connecting a host device 10 to communication modules 21, 22, and 23 generates a replica of communication data between the host device 10 and a first communication partner 41, and accumulates the communication data in a communication data storage unit 152a. When the communication with the first communication partner 41 is completed, the connection adapter 1 is connected to the second communication partner 51. Then, the communication data stored in the communication data storage unit 152a is transmitted to the second communication partner 51.

Abstract: A method of manufacturing a semiconductor device characterized by its high-speed operation and high reliability is provided in which a semiconductor layer crystallized by a CW laser is used for an active layer of a TFT. When a semiconductor layer is crystallized by a CW laser, one part is formed of large crystal grains whereas another part is formed of microcrystals due to the width-wise energy density distribution. The former exhibits excellent electric characteristics. The latter has poor electric characteristics because grain boundaries hinder movement of electric charges, and therefore causes inconveniences when used as an active layer of a transistor. Accordingly, circuits are arranged such that a semiconductor layer formed of large crystal grains is used for the active layer of every TFT.

Abstract: A connection adapter is interposed between high-level equipment and a communication module. The connection adapter and a router perform a circuit control and an address conversion processing so that the high-level equipment and a management computer set for the network connection service giving a fixed IP address can use the network connection service giving a dynamic IP address.

Abstract: A host computer transmits a user ID and a list of vending machine IDs to a portable communication terminal. When the user selects from the list a vending machine through which the user makes a payment, the user ID and the ID of the selected vending machine are transmitted from a portable communication terminal to the host computer. The host computer issues to the vending machine corresponding to the vending machine ID an instruction to enter a payment acceptable mode. When the user makes a payment at the vending machine, the amount of the payment is transmitted to the host computer.

Abstract: A customer operates his portable communication terminal to call a vending management center and to transmit a purchase request for buying an item from an intended one of a plurality of automatic vending machines. The vending management center transmits a selling allowance to the intended automatic vending machine. The automatic vending machine, in accordance with the selling allowance, delivers an item indicated by the customer. Thus the customer can obtain his desired item. The automatic vending machine, after delivering the item, transmits dispensing result data to the vending management center. Then, the vending management center prepares user and sales data from the dispensing result data and transmits the user and sales data to a proprietary of the communication network accommodating the portable communication terminal. Subsequently, the proprietary, in accordance with the user and sales data, settles an account with the customer on the communication fee and the item price.
