摘要: A multi-master node model database management technology involves notifying a higher-level master node of a transaction minimum value as a minimum value of an implementation-underway transaction in a snapshot from a lower-level master node, comparing the transaction minimum value with minimum values retained by the respective master nodes and thus updating a node minimum value and a cluster minimum value. Then, the lower-level master node transmits a write set containing a shadow copy of its own database, a heap tuple map deployed on its own memory and the transaction minimum value to the higher-level master node, and the higher-level master node receiving the write set updates the database by use of the write set if the transaction minimum value is equal to or larger than the cluster minimum value, and aborts the write set if the transaction minimum value is smaller than the cluster minimum value.

摘要: A distal side link hub is connected with a proximal end side link hub through three sets of link mechanisms for alteration in posture. At least two sets of the link mechanisms include an actuator for arbitrarily changing the posture of the distal end side link hub relative to the proximal end side link hub by rotating a proximal side end link member and a reduction gear unit for reducing the speed of and transmitting the operation amount of the actuator to the proximal side end link member. The reduction gear unit includes a geared speed reducing section having a small gear rotated by the actuator and a large gear provided in the proximal side end link member. The radius of pitch circle of the large gear is chosen to be equal to or greater than the arm length of the proximal side end link member.

摘要: A motor drive device is provided which allows control to be performed depending on a position of magnetic poles of a rotor even when a motor rotor angle sensor malfunctions. The device controls a motor for driving a wheel of an electric vehicle, depending on the position of the magnetic poles by using an angle sensed by the angle sensor provided at the motor. The device includes an estimator estimating an angle of a rotor of the motor without using a rotation sensor; a sensor malfunction determiner determining a malfunction of the angle sensor; and a switcher causing control to be performed using a angle estimated by the estimator instead of the angle sensed by the angle sensor once the determiner determines that the angle sensor malfunctions.

摘要: It is a calibration device for a measurement instrument for measuring a compressive force or a tensile force in a longitudinal direction exerted to a linear body from a predetermined correlation. A stopper part for fixing the linear body is fixed at a one end side entrance and a push/pull movable part for enabling the linear body to be pushed and pulled in an insertion/withdrawal direction at an other end entrance is fixed, so that the relative positions of the stopper part and the push/pull movable part with respect to a sensor main body cannot be changed. A force detector measures the force in the insertion/withdrawal direction exerted from the push/pull movable part to the linear body. The force detector is interposed between the push/pull movable part and the linear body.

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.
