    摘要： A soldering flux which is suitable as a no-clean post flux in flow soldering and which can prevent the formation of whiskers which tends to occur when soldering electronic parts to a printed circuit board using a lead-free solder (such as Sn-3.0Ag-0.5Cu) having a higher Sn content and a higher melting point than the eutectic solder contains, in addition to a rosin as a base resin and an activator, 0.2-4 mass % of at least one compound selected from acid phosphate esters and derivatives thereof. The formation of whiskers can be more effectively prevented by carrying out soldering in a nitrogen atmosphere.

    摘要： This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented.

    摘要： An evaporative pattern casting process includes forming a mold by burying a pattern made of resin foam in casting sand, pouring molten metal into the mold, and evaporating the pattern with the molten metal and thereby casting a product. In the evaporative pattern casting process, casting time during founding is set according to a modulus (pattern volume÷pattern surface area) of the pattern. Accordingly, the casting time in the evaporative pattern casting process is accurately set with high precision.

    摘要： The present invention realize a method of managing a database capable of hierarchically building master nodes, and efficiently performing the update of the master nodes. A lower-level master node sends, to a higher-level master node, a write set expanded in its own memory including a shadow copy of its own database and a heaptuple map, and the higher-level master node that received the write set verifies whether the update has already been executed and sends the record of this update to the lower-level master node as a transaction log, whereby the database can be updated efficiently and consistently from the lower-level master node to the higher-level master node, and from the higher-level master node to the lower-level master node under its control.

    摘要： [Problem]To prevent an eccentric load from occurring in a nut member of a linear actuator and ensure a longer service life of the nut member.[Solution]The nut member is coupled to a driven member by a contact force equalizing mechanism having two rotation axes which are virtually perpendicular to each other, to absorb slight inclination between the nut member and the driven member and prevent occurrence of an edge load; also the point of intersection which is obtained when the two rotation axes are projected toward a threaded shaft is set as an optimum point of application of load for the nut member to let an external force transmitted from the driven member act on the optimum point of application of load to equalize the loads applied to the contact portions between the nut member and the threaded shaft and thereby prevent an eccentric load from occurring in the nut member.
