Abstract: The grain-oriented electrical steel sheet according to the present embodiment is a grain-oriented electrical steel sheet having a base steel sheet (1), an intermediate layer (4) disposed to be in contact with the base steel sheet (1), and an insulation coating (3) disposed to be in contact with the intermediate layer (4). The grain-oriented electrical steel sheet according to the present embodiment includes a surface of the base steel sheet (1) having a strain region (D) which extends in a direction intersecting a rolling direction of the base steel sheet (1), and a crystalline phosphorus oxide M2P4O13 present in the insulation coating (3) on the strain region (D) in a cross-sectional view of a surface parallel to the rolling direction and a sheet thickness direction of the base steel sheet (1). (M means at least one or both of Fe and Cr.

Abstract: A bus-protocol converting device includes: a command detecting unit that detects a command sent from an external-memory control device, connected to a primary bus, to a primary bus interface controller; a command converting unit that converts the detected command into a command to be sent from a secondary bus interface controller to an external memory device through a secondary bus; a status detecting unit that detects a status sent from the external memory device; a status converting unit that converts the detected status into a status to be sent from the primary-bus interface controller to the external-memory control device through the primary bus; and a data transfer controller that is provided between the primary bus interface controller and the secondary bus interface controller to perform data transfer between the external-memory control device and the external memory device through a DMA bus.

Abstract: An interface card includes data transmission routes which allow for data transmission in a plurality of data transmission modes and a mode selection switch for selecting a data transmission mode from the plurality of modes. With the interface card, a user is able to select an optimal data transmission mode for the environment.

Abstract: A device controller is used for controlling PCI devices or card devices on an add-inboard. To install multiple devices including a master device on the add-in board, and to build a multifunction PCI device or card device by smoothly controlling their operation, a device controller (1) is provided with a bus arbiter circuit (17) for handling bus mastering request from devices (D1-D8). The device controller causes the bus arbiter circuit (17) and a target detect circuit (16) to detect an initiator and a target, and a bus sequencer (2) to control signal issuing operation in a bus mastering cycle, for example, by an appropriate procedure based on the result of the detecting operation. An add-in board (30) is recognized as a single multifunction device.

Abstract: An interface card is connected to a first data bus with a first bit width (for example, 16-bit width) and has a data storage section which is capable of storing data of a second bit width (for example, 32 bits of data) which is larger than the first bit width. Between the data storage section and an information processing device, data transmission is carried out via a second data bus with the second bit width.
