A method is provided for manufacturing a magneto-resistive device. The magneto-resistive device is for reducing the deterioration in the characteristics of the device due to annealing. The magneto-resistive device has a magneto-resistive layer formed on one surface side of a base, and an insulating layer formed of two layers and deposited around the magneto-resistive layer. The layer of the insulating layer closest to the base is made of a metal or semiconductor oxide. This layer extends over end faces of a plurality of layers made of different materials from one another, which make up the magneto-resistive device, and is in contact with the end faces of the plurality of layers with the same materials.

A semiconductor package includes a base plate; a sidewall provided at a periphery of the base plate; a sensor chip retained in a chip accommodation space defined by the sidewall; and a chip installation hole provided in the base plate for installing the sensor chip. The sensor chip is disposed in the chip installation hole provided in the base plate of the case. Accordingly, it is possible to reduce a thickness of the semiconductor package without changing a thickness of the sensor chip. The base plate has a relatively large thickness except for the chip installation hole. Accordingly, even when the semiconductor package is made thinner, rigidity of the base plate is maintained, thereby minimizing a strain in the base plate.

An IC card that has improved endurance and demonstrates increased resistance to cracking of the case and peeling of the substrate when a bending force acts upon the IC card. First protrusions and second protrusions are formed in a recess for fitting a LGA. The second protrusions are connected to the side wall of the recess on the card center side. Because the first protrusions maintaining a constant and correct gap between the bottom portion and LGA, that is, a constant and correct thickness of an adhesive, and the second protrusions are provided, the LGA and case can be reliably bonded together. The boundary portion with the thick portion of the recess on the card center side is a portion where stresses are easily concentrated and cracks can easily occur. However, because the second protrusions provided in the bottom portion of the recess are integrally connected to the side wall, the boundary portion is reinforced and stress concentration is relaxed. As a result, the occurrence of cracking from the boundary portion can be inhibited.

When inconsistency occurs between data presented from individual group enterprises, causes of the inconsistency cannot be specified easily in a conventional consolidated settlement processing method. In the embodiments of the invention, an XBRL conversion module converts inputted account data into data resulting from synthesis of standard data and extended data by using a mapping table and transmits the converted data to a data separation module. The data separation module separates the standard data and extended data of the received data and stores these types of data in corresponding storage tables while adding them with information for mutual relevancy. In this manner, when inconsistency occurs during a consolidated settlement process, causes of the inconsistency can be specified easily by acquiring the extended data.
