    摘要: The present invention is a urea production method, including: a first concentration step of concentrating an aqueous urea solution; a granulation step of producing solid urea from the concentrated urea solution generated in the first concentration step; a urea recovery step of treating exhaust gas from the granulation step and recovering urea dust in the exhaust gas to generate a recovered aqueous urea solution, the granulation step being configured so as to treat a concentrated urea solution containing an additive; and a second concentration step of concentrating the recovered aqueous urea solution as an additional concentration step, wherein the concentrated recovered urea solution generated in the second concentration step is joined to the concentrated urea solution in the downstream of the first concentration step, and an additive is added downstream of the first concentration step.

    摘要: The field of the invention relates to interactive computer systems and more particularly to systems and methods for simulating a particular user's behavior in an interactive computer system. In one embodiment, a computer program product includes a simulator configured to simulate a user interacting with a computer program. The simulator includes a learning mode of operation and a simulation mode of operation. During the learning mode, the simulator is configured to monitor the user's interaction with the computer program for one or more events and analyze one or more current circumstances during the occurrence of the one or more events. The simulator is further configured to record one or more user inputs in response to the occurrence of the one or more events, store the one or more user inputs in one or more data fields, and associate the one or more data fields with the one or more events and the one or more current circumstances. During the simulation mode of operation, the simulator is configured to monitor the computer program for the one or more particular events, retrieve the one or more data fields associated with the one or more particular events, analyze one or more current circumstances upon the occurrence of the one or more particular events, and invoke one or more simulated inputs based on the value of the one or more data fields in response to the occurrence of the one or more events and the one or more current circumstances.

    摘要: The present invention is a sliding contact material having a composition of Cu of 6.0% by mass or more and 9.0% by mass or less, Ni of 0.1% by mass or more and 2.0% by mass or less, an additive element M of 0.1% by mass or more and 0.8% by mass or less, and the balance being Ag. The additive element M is at least one element selected from the group consisting of Sm, La and Zr. The present sliding contact material has a material structure in which dispersion particles containing an intermetallic compound containing at least both Ni and an additive element M are dispersed in an Ag alloy matrix. It is required that the ratio of a Ni content (% by mass) and a content of an additive element M (% by mass) (KNi/KM) in the dispersion particles falls within a predetermined range. The present invention is an Ag alloy-based sliding contact material more excellent also in abrasion resistance than conventional ones, and a material adaptable to higher rotation numbers of micromotors.

    摘要: The present invention relates to a package production method includes the step of superposing a pair of substrates on each other, and bonding the substrates to each other to hermetically seal the inside of a sealing region surrounded by a sealing material, which is formed on any of the substrates. The sealing material is formed of a sintered body obtained by sintering a metal powder of at least one selected from gold, silver, palladium and platinum, the metal powder having a purity of 99.9% by weight or more and an average particle size of 0.005 μm to 1.0 μm, at least one core material having a width smaller than the width of the sealing material in a cross-sectional shape, and protruding from the periphery is formed on the substrate, and the core material compresses the sealing material to exhibit a sealing effect when the pair of substrates are bonded to each other. Accordingly, a sufficient sealing effect can be exhibited while a pressuring force to the substrate is reduced.

    摘要: Methods and systems for distributed computation of graph data permit edge collection and vertex collection, each to be partitioned among a plurality of computational units. In one embodiment, the methods employ a two-phase computational cycle, which is repeated until the computation is complete. In a first phase, processing units process each active edge and vertex by doing the following: reading their current attribute values, executing programmed computational functions, updating edge attributes and sending data messages to vertices. In a second phase, each vertex update processor processes each of its active vertices by doing the following: reading its current attribute values and received data messages, executing a programmed computational function, and updating the vertex's attribute values.

    摘要: An electronic component cap for producing a package having a sealed region by being bonded to a base, having a brazing material-fused surface to which a brazing material is fused and a sealing surface corresponding to the sealed region. The brazing material-fused surface has a non-flat work surface formed by plastic working, and a ratio (Sc/Sf) of a surface area (Sc) of the brazing material-fused surface per unit area to a surface area (Sf) of the sealing surface per unit area satisfies 1
