  • Patent number: 10936518
    Abstract: An object of the present invention is to properly secure the consistency of data while suppressing a processing load of a controller on a processor. A storage system includes a plurality of controllers and an HCA that can directly access a memory and can communicate with the controllers. The controller includes a CPU, and a memory having a buffer region into which data is temporarily stored and a cache region into which data is cached. In the case where new data according to a write request is stored into the buffer region, the CPU of the controller sequentially transfers the new data to the cache regions using the HCA without passing through the other buffer regions.

  • Publication number: 20200400238
    Abstract: A spacer having a wedge-shaped flat plate portion and an engagement protrusion is interposed between a hole end surface of mounting hole of a valve plate and a rod end surface of mounting portion of a valve rod, which thereby forms a wedge-shaped gap between the spacer and the hole end surface so as to open frontward. A fastening force of a valve-plate fixation screw generates a moment M that deforms the valve plate in a direction of narrowing the gap. At the same time, the engagement protrusion of the spacer is pressed into a wedge-shaped space between the inclined surface portion of the rod end surface and the rear hole-wall surface of the mounting hole, which causes the front hole-wall surface of mounting hole of the valve plate to press the rod front surface of mounting portion of the valve rod.

  • Publication number: 20200395329
    Abstract: In a wiring member, an element connection portion, a plate connection portion, and an upper surface portion are at height positions different from one another. The element connection portion has a through hole, and the plate connection portion has a through hole and a chamfer. The upper surface portion which is not connected to another portion, has projections asymmetrically disposed on both side surfaces thereof. Owing to these features, the type, the orientation, and the front and the back of the wiring member can be easily distinguished. Accordingly, it is possible to prevent incorrect assembling of the wiring member in a semiconductor module.

  • Publication number: 20200395271
    Abstract: A shared base plate includes a plurality of base portions to which a plurality of electronic components including semiconductor switching elements are to be mounted, and a terminal formed portion formed so as to extend from the base portion to the outer side. The terminal formed portion includes a discrimination terminal which is used as a terminal in one of a first semiconductor module and a second semiconductor module and which is not used as a terminal in the other one. If the discrimination terminal that is not used as a terminal is cut to be short, it becomes possible to easily discriminate the semiconductor module from another semiconductor module having the shared base plate by outer appearances.

  • Publication number: 20200310975
    Abstract: A storage system includes a plurality of controllers and a plurality of storage drives. A first cache area and a second cache area are set in a memory. The first cache area is permitted to be written data by the plurality of storage drives, and the second cache area is not permitted to be written data by the plurality of storage drives. In a case where the plurality of controllers duplicates data stored in the cache area to a cache area of another controller for redundancy, the plurality of controllers causes the data to be redundant in a second cache area of the other controller in a case where the data is stored in the first cache area, and causes the data to be redundant in a first cache area of the other controller in a case where the data is stored in the second cache area.

  • Patent number: 10789228
    Abstract: A storing unit stores a data set including a plurality of data elements and a first Bloom filter used to determine whether a query-target data element is present in the data set. A calculating unit deletes, when some data elements are deleted, a first bit array from the first Bloom filter. The first bit array has the number of bits corresponding to the number of deleted data elements. When a query-target first data element is entered, the calculating unit adds a second bit array temporarily to a second Bloom filter obtained by deleting the first bit array. The second bit array has the same number of bits as the first bit array, with all bits set to a specific value. Using the second Bloom filter, the calculating unit determines whether the first data element is present in the data set, from which some data elements have been deleted.
