  • Publication number: 20120233419
    Abstract: An embodiment of this invention schedules data replications for backing up a first storage system providing a plurality of applications with volumes to a second storage system. This scheduling determines scheduled finish times of respective data replications for the plurality of applications and determines start times of the respective data replications for the plurality of applications from the scheduled finish times of the respective data replications and the respective amounts of data to be transferred for the plurality of applications, using a data transfer rate between the storage systems and an overlap degree of data replication periods of the plurality of applications.

  • Patent number: 6890417
    Abstract: An electrolytic bath is divided into an anodic chamber and a cathodic chamber by a cation-exchange membrane. A base alkaline solution of high impurity concentration is supplied into the anodic chamber from a tank of a base material as well as a circulating anolyte overflowed from the anodic chamber is supplied and circulated from an anode circulating tank, and NaOH solution of low impurity concentration is supplied and circulated into the cathodic chamber through a tank of a refined solution. The concentration of the circulating anolyte is detected, and based on this detected value the supplying amount of the base NaOH solution is controlled and electrolysis is performed. Thus, the concentration of NaOH solution in the anodic chamber is kept stable, and the refined NaOH solution of low impurity concentration can be obtained in the cathodic chamber.

  • Patent number: 6880374
    Abstract: In a steering lock device wherein engagement and disengagement of a lock pin to and from a steering shaft can be selected by the rotation of a rotor, the steering lock device comprises: interlocking structure provided between a cylinder body and a joint so that when the cylinder body is pulled out from a housing, the interlocking structure causes the joint to move in an axial direction together with the cylinder body; an axial movement preventing member disposed in the housing so as to be moveable in a direction perpendicular to the axis of the joint to engage the joint and thereby prevent the axial movement of the joint when the joint is pulled out a predetermined distance; and a rotation preventing portion provided to the housing so as to engage an outer circumferential surface of the joint to thereby prevent rotation of the joint in a state that the axial movement preventing member engages the joint.

  • Patent number: 5831441
    Abstract: A test board used for testing a semiconductor device provided with projection electrodes includes a main board and testing electrodes. The testing electrodes are provided on the main board, each projecting upwardly from the main board. When the semiconductor device is tested, the testing electrodes are electrically connected to the projection electrodes by insertion of the testing electrodes into the projection electrodes. The semiconductor device is mounted on the main board to test the semiconductor device through the testing electrodes.

  • Patent number: 4945740
    Abstract: A vehicle steering lock device mounted to an automotive vehicle, in which a rotor in a cylinder lock is rotated to a lock position by the operation relevant to the rotor, comprises switching means for detecting a specific pushing operation to the rotor, etc. and switching means for detecting the situation of a shift lever to a parking position or not, in which rotation of the rotor to the locking position is allowed or inhibited in accordance with signals from both of the switching means and which enable safe parking on a downward slope and can prevent erroneous steering lock operation during down hill running without engine driving.
