  • Patent number: 10883441
    Abstract: The fuel injection timing IT is changed based operation and environmental condition of the engine. If the injection timing IT is changed, the rate of fuel passing through meshes of the mesh member (i.e., the mesh passing rate) changes. If the mesh passing rate changes, the set-off position (i.e., the ignition position of the air-fuel mixture) is extended or shortened. Based on this, under the condition of high ignition performance (i.e., the second condition), the mesh passing rate is controlled to increase thereby the set-off position is extended. On the other hand, under the condition of low ignition performance (i.e., the first condition), the mesh passing rate is controlled to decrease thereby the extension of the set-off position is suppressed or prohibited.

    Abstract: According to one embodiment, an image interpretation report creating apparatus that creates an image interpretation report including a finding and is associated with a key image, includes a key image selecting unit, a position detecting unit, a first local structure information generating unit, and a display. A key image selecting unit selects a sub-image as the key image from among a plurality of sub-images comprising a medical image. A position detecting unit detects a position of a characteristic local structure in a human body from the medical image. A first local structure information generating unit identifies a local structure in the key image or in a vicinity of the key image and generates information on the identified local structure as first local structure information. A display displays the first local structure information as a candidate to be entered in an entry field for the finding.

  • Patent number: 8817490
    Abstract: A DC-DC converter is configured with a voltage-source power converter at a primary side of a transformer, a current-source power converter at a secondary side of the transformer, and a controller. First and second voltage detection circuits respectively detect first and second voltages of the voltage-source and the current-source power converters. A current detection circuit detects an input-output current of the current-source power converter. The controller controls the voltage-source and the current-source power converters to transfer power between the primary side and the secondary side of the transformer. The controller includes a calculation unit that performs calculations based on the first voltage, the second voltage and the input-output current, and a table unit that include a plurality of parameter sets. The calculation unit performs the calculations based on one of the plurality of parameter sets that is selected from the table unit.

  • Patent number: 8330717
    Abstract: In the medical image interpreting apparatus having a pointing device for moving a cursor, medical image, interpretation report, and cursor are displayed on a display screen, and initial movement information and information on the destination of movement of the cursor are linked and stored, via the pointing device when the cursor begins to move, said initial movement information relevant to the initial movement is retrieved to obtain the linked information on the destination of movement and the cursor is moved to the destination of movement indicated in the obtained information on the destination of movement. Due to this, just by slightly moving the cursor, the cursor jumps to the desired destination of movement, therefore, it becomes possible to omit an operation of the pointing device in between.

  • Patent number: 8184878
    Abstract: Specific information for specifying a specific study or series for which an object, which is obtained by adding at least one information of a scan condition, a scan range, and a key image position as a basis of a diagnosis in an image, is to be generated is specified. It is determined whether or not an image for references is present in the specific study or series on the basis of additional information of at least one image related to the specific study or series. When it is determined that the image for references is present, an object about the specific study or series is generated afterwards, for example, in the unit of series by using the image for references and at least one information of a scan condition, a scan range, and a key image position of the additional information.
