Abstract: It is an object of the present invention to enable a buyer to collectively manage information related to a variety of commercial transactions performed by the buyer as well as to the settlements for these transactions. The calendar server 25 supplies a calendar screen to a buyer system 3 that is used by the buyer 1. This calendar screen has electronic invoices addressed to the buyer 1, which are issued by the supplier system 7, and electronic deposit/withdrawal detailed statement of the buyer's deposit account, which are issued by a banking system 13, pasted in the spaces for the relevant dates. When the buyer 1 selects an arbitrary invoice on this calendar screen and inputs his or her approval of this invoice, an account transfer telegraphic message for payment of this invoice is automatically sent to the banking system 13.

Abstract: Described herein are methods and apparatus for the processing of electronic invoices. A server for processing invoices communicates with computing systems such as a supplier system (used by a supplier), a buyer system (used by a buyer), and finance systems (which manage bank accounts of the supplier and buyer). The server communicates with the supplier system and the buyer system regarding an electronic invoice that relates to a transaction between the supplier and the buyer, and that includes a unique identification code. When the buyer has approved the electronic invoice, the supplier system and/or the server is able to settle the invoice using the unique identification code.

Abstract: A photoelectric conversion sensor for measuring particle size or size distribution based on the light scattering phenomena with excellent precision and higher resolving power. The sensor is characterized in that 8 or more arcuate photoelectric conversion elements each being defined by two concentric arcs with different radii and two adjacent elements in the radial direction are so arranged that the gaps in the radial direction between two adjacent elements in the radial direction can be substantially eliminated by shifting them in the circumferential direction.
