Patent number: 10883441Abstract: 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.Type: GrantFiled: April 15, 2019Date of Patent: January 5, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Jun Kawakami

Patent number: 8330717Abstract: 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.Type: GrantFiled: September 23, 2010Date of Patent: December 11, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Jun Kawakami, Kenichi Niwa, Maki Minakuchi, Takashi Kondo, Takashi Masuzawa
