Abstract: A fuel cell system has a plurality of fuel cells stacked in one or more groups of fuel cells. Each fuel cell includes a fuel electrode supplied with fuel gas at a fuel gas supply pressure, an oxidizing electrode supplied with oxidizing gas at an oxidizing gas supply pressure, and an electrolyte membrane disposed between the fuel electrode and the oxidizing electrode. A pressure-difference control unit generates a pressure difference across the membrane such that the fuel gas supply pressure is greater than the oxidizing gas supply pressure in each fuel cell, a cell-voltage measuring device measures a cell voltage for each fuel cell or each group of fuel cells in the fuel cell stack, and a leakage determination unit determines the presence or absence of a leaking cell based on the behavior of the cell voltage of each fuel cell while the pressure difference is increased with time.

Abstract: Objects which are created in conformity with the data format of objects to be handled in a virtual world are offered to users on the terminal computers of the users independently of the virtual world. The users transmit the offered objects to a server computer which generates the virtual world, while the server computer stores these objects in association with the operators. Since these objects are recorded in a format which can be interpreted by the server computer for generating the virtual world, they can be handled in the virtual world in the same manner as the other objects which have been defined in the virtual world beforehand. Thus, the users are permitted to use in the virtual world objects which are different from the objects which were defined in the virtual world beforehand.

Abstract: In a liquid-metal cooled reactor equipped with a primary cooling system, a secondary cooling system and a steam turbine power generation system, or equipped with a primary cooling system and a steam power generation system, an alkali metal thermoelectric converter is disposed between the primary cooling system or the secondary cooling system and the steam turbine power generation system. Heat of the primary cooling system or the secondary cooling system is supplied to a high-temperature side of the alkali metal thermoelectric converter and waste heat on a low-temperature side of the alkali metal thermoelectric converter is supplied to the steam turbine power generation system. Thus, power generation by the steam turbine power generation system is performed simultaneously with power generation by the alkali metal thermoelectric converter. As a result, the power generation efficiency of the whole plant can be significantly increased.

Abstract: For image processing for printing an original, first and second ground patterns are generated. The first ground pattern can be recognized with naked eyes in the original but cannot be recognized with naked eyes in a reproduction of the original obtained by an image forming apparatus, while the second ground pattern has a latent image which cannot be recognized in the original but can be recognized in the reproduction of the original. The first ground pattern and the second ground pattern are synthesized, and print data to be printed by the image forming apparatus is created. The print data has an image of the original, and the synthesized first and second ground patterns.

Abstract: An electronic apparatus has a housing having one end, components contained in the housing, and a door which is lockable at a closed position to hide one end of the housing. The housing has a base to support the door, and a cover connected removable to the base. The cover is removed from the base by sliding toward the door, and hooked on the base by sliding away from the door. The door prevents the cover from sliding in the direction of separating the cover from the base, as long as being locked at the closed position.

Abstract: In image data retrieval, image data that becomes the base of search is specified. When the search is to be carried out according to the distance from the image data on an image map, an automatic setting process of retrieval information is carried out. Here, a keyword, icon, chromaticity and the like of that image data are automatically set as retrieval information. The position of that image data on the image map becomes the center of a range when the ambiguity is set. By setting the ambiguity of the image map, keyword, icon, chromaticity, and the like in this state, the range of ambiguity is displayed, and image data within that range is automatically retrieved. As a result, analogous image data can be searched for according to subtle and ambiguous information or information that cannot be quantified.

Abstract: Disclosed are a composite material having an anti-wear property and a process for producing the same. The composite material includes a matrix of a low melting point Sn alloy having a melting point of from 80.degree. to 280.degree. C., and metallic dispersing particles dispersed in the matrix in an amount of from 10 to 50% by volume. When the composite material is utilized to make a rough mold for preparing a prototype, it sharply improves the anti-wear property of the rough mold, and it can be re-used for a plurality of times without adversely affecting the sharply improved anti-wear property. The composite material provides the advantages effect best when the metallic dispersing particles are Fe-C alloy dispersing particles and/or Fe-W-C alloy dispersing particles which were subjected to a surface treatment including an Sn or Ni electroplating followed by a ZnCl.sub.2 .cndot.NH.sub.4 Cl flux depositing.
