摘要:
A method for manufacturing granular metallic iron includes charging a raw-material mixture into a thermal reduction furnace, subjecting the raw-material mixture to thermal reduction to form metallic iron and slag as a by-product, causing metallic iron to coalesce into granules while separating metallic iron from slag, and cooling and solidifying metallic iron. The raw-material mixture contains at least Fe, Ca, Mg, Si, and an alkali metal as constituent elements in such a manner that the slag contains CaO, MgO, SiO2, and an alkali oxide, the alkali oxide is at least one selected from Li2O, Na2O, and K2O, the alkali oxide satisfies at least one of Li2O content≧0.03%, Na2O content≧0.10%, and K2O content≧0.10%, and the basicity of the slag is in the range of 1.3 to 2.3. It is possible to manufacture high-quality granular metallic iron with good productivity by the method.
摘要:
A method for producing granular metallic iron by heating and reducing a raw material mixture which includes an iron oxide-containing material, a carbonaceous reductant and a Li2O supplying material in a thermal reduction furnace, wherein the iron oxide-containing material includes a hematite-containing material, and the raw material mixture includes at least Fe, Ca, Mg, Si and Li as constituent elements in such a manner that slag which forms as a by-product during heating and reduction contains CaO, MgO, SiO2 and Li2O, has a Li2O content of 0.05% by mass or more, and the slag has a basicity [(CaO+MgO)/SiO2] in a range of from 1.5 to 1.9. This method enables granular metallic iron to be produced at a high productivity even when a hematite-containing material is used as the iron oxide-containing material.

To provide a technique by which an —OH group can be effectively formed on a material surface for the purpose of making the material suitable for bonding (for example, for molecular bonding) that utilizes a chemical reaction (chemical binding). [Solution] A bonding method for bonding a substrate A and a substrate B, which comprises: a step for applying an agent that contains the compound (α) described below on the surface of the substrate A; a step for arranging the substrate B so as to face the compound (α) that is present on the surface of the substrate A; and a step for integrally bonding the substrate A and the substrate B by applying a force onto the substrate A and/or the substrate B. The compound (α) is a compound that has an OH group or an OH-forming group, an azide group and a triazine ring in each molecule, and the substrate A is configured using a polymer.

The users are allowed to easily retrieve contents data such as recipe data. A personal computer (103) receives recipe data from a server (101) via a communication network (102), and stores the received recipe data in a memory card (104). The personal computer updates recipe hierarchical information (142) in the memory card (104), i.e., information which indicates classified levels of recipe data based on retrieval keys, with reference to overall hierarchical information (133), i.e., information which indicates the hierarchical relation of retrieval keys in the whole recipes, so that the newly stored recipe data is included in the recipe hierarchical information.

A biometric authentication device has high security by preventing intra-device information from being falsified and stolen by a third party. A biometric authentication device includes a biometric information storage module, a biometric information authenticating module for individual authentication, a mutual authentication module with the terminal, a registration counter corresponding to the mutual authentication, an authentication counter corresponding to the biometric authentication, a stoppage flag set when the value of the counter is larger than a predetermined value, and authentication control module for preventing the module from operating depending on the stoppage flag.
摘要:
An optical logic device performs a logic operation on a plurality of input light signals. The optical logic device has a photoelectric conversion portion, in which photoreceivers for receiving input light signals are provided in parallel, that outputs an electric signal obtained by adding up outputs of the photoreceivers, and a comparator that compares a voltage level of the electric signal outputted from the photoelectric conversion portion with a predetermined voltage level.

The present invention includes: a current position determination unit (101) that determines a current position of a user; a facility candidate search unit (103A) that specifies, as a candidate for a visited place, a facility that is located within a predetermined area including the current position determined by the current position determination unit (101); an electronic money unit (108) and a payment amount calculation unit (104) that detect a payment amount of the user; and a most-likely visited facility identification unit (105A) that identifies a most-likely visited place by selecting from a plurality of facilities a facility corresponding to the payment amount detected by the electronic money unit (108) and the payment amount calculation unit (104), when the plurality of facilities are specified by the facility candidate search unit (103A).
摘要:
A movement history of the user is transmitted from each of a plurality of terminals (11) owned by the user to a movement history management server (13). The server (13) filters display-conditioned information received from an information provider terminal (14) by referring to the display conditions of the information and the stored user's movement histories, to specify display-conditioned information to be transmitted, and transmits the specified information to the user.
摘要:
In an information acquisition system such as a car navigation system, a history accumulation DB 104 accumulates user's travel history. A condition determination section 107 determines a condition for retrieval for performing accurate prediction, and a prediction section 108 predicts a travel destination using the condition for retrieval. An information-to-be-presented determination section 110 acquires information relating to the travel destination predicted by the prediction section 108 from a received information DB 802 or the like.
