Abstract: A display panel includes: a substrate having a surface, and a plurality of pixels; and one or more light emitting elements for each pixel. The plurality of pixels are placed at different positions on the surface of the substrate. The pixels are disposed so that an occupancy rate of the light emitting elements is lower in a first region, which is part of the surface of the substrate, than in a second region, which is a region surrounding the first region and so that in the second region, the occupancy rate increases with a distance from the first region.

Abstract: A transaction processing method is provided for a transaction management system which processes transactions using settlement cards. In the transaction processing method, a transaction process is executed based on individual control information that is input at each transaction and transaction information for the transaction. A judgment is made based on the transaction information whether or not the transaction satisfies at least one count-up condition indicating a predetermined range of transaction types. When the transaction meets the count-up condition, numerical information indicative of the number of transactions satisfying the count-up conditions is added. A determination is made whether or not a numerical value represented by the numerical information after the addition is within a range specified by extraction conditions.

Abstract: An electronic settlement system processes settlements that are conducted using credit cards through a communication line connecting a server of a credit card company to card-processing devices of member stores or terminals of customers. The electronic settlement system includes a device that provides personal information of customers to member stores based on the agreement by the customers to provide such personal information, and a device that provide the customers with preferred services either from the credit card company or the member stores in exchange for the personal information provided. Furthermore, the electronic settlement system may includes a device at the card company to receive fees for providing the member stores with the personal information of the customers. The electronic settlement system enables the customers to receive services, the member stores to utilize accurate personal information, and the card company to receive fees from the member stores.

Abstract: A sintered metal part has a magnesium metasilicate mineral, or a magnesium metasilicate mineral and a magnesium orthosilicate mineral, or at least one of a magnesium metasilicate mineral and a magnesium orthosilicate mineral and at least one of boron nitride and manganese sulfide dispersed throughout the metal matrix. An iron-based sintered sliding member is of a structure that free graphite and an intercrystalline inclusion have been dispersed throughout the metal matrix that consists essentially of, in weight ratio, 1.5 to 4% of carbon, 1 to 5% of copper, 0.1 to 2% of tin, 0.1 to 0.5% of phosphorus, 0.
