  • Patent number: 11128889
    Abstract: To achieve a reduction in the amount of coding taken in the use of an asymmetric partition and to implement efficient encoding/decoding processes exploiting the characteristics of the asymmetric partition. An image decoding device includes a motion compensation parameter derivation unit configured to derive a motion compensation parameter indicating either a uni-prediction scheme or a bi-prediction scheme. In a case that a prediction unit has a size less than or equal to a predetermined value, the motion compensation parameter derivation unit is configured to derive the motion compensation parameter by switching between the prediction schemes.

  • Publication number: 20210278989
    Abstract: In a case of exchanging a migration source storage controller and a migration destination storage controller sharing one storage medium during replacement of storage devices, when hardware configurations or data management forms of the storage controllers are different, data in the storage medium cannot be shared even when data management information can be copied. Accordingly, a storage system, having a storage control unit and a storage drive provided with a storage medium, includes data management information for accessing data in the storage drive. A first storage control unit copies data management information about the data in the storage drive to a second storage control unit. When a write request is received from a host after copying of the data management information begins, each of the first storage and second storage control units stores write data related to the write request in a separate storage area of the storage drive.

  • Publication number: 20210268808
    Abstract: A laser recording method is for processing a recording object with laser light emitted from a laser light source. The laser recording method includes: detecting a moving speed of the recording object with a location of the laser light source when the laser light source emits laser light, as an observation point, while moving at least one of the recording object and the laser light source; and correcting power output of the laser light set such that an amount of energy applied by the laser light per unit area of the recording object is constant even if the moving speed is changed, to compensate energy loss derived from thermal diffusion occurring on the recording object based on the moving speed detected at the detecting.

  • Patent number: 9914159
    Abstract: Provided is a method for producing a plug for use in a piercing-rolling mill for producing a seamless steel tube/pipe, and the method for producing the plug for piercing-rolling comprises shotblasting a surface of the plug, and arc-spraying a spray wire so as to form a film on a surface of a base metal of the plug that is shotblasted. In the arc-spraying step, the arc spraying is carried out by using, as the spray wire, a cored wire whose iron sheath tube is charged with at least iron oxide particles among iron particles and the iron oxide particles (one or more of FeO particles, Fe3O4 particles, and Fe2O3 particles), so as to form the film containing iron oxide and Fe. Accordingly, it is possible to enhance the production efficiency of the plug, and to produce the plug for piercing-rolling capable of securing the steady enhancement of the durability life of the plug during the piercing-rolling.
