  • Patent number: 10742210
    Abstract: A drive circuit drives switches that are connected to each other in parallel. The drive circuit includes individual discharge paths, a common discharge path, blocking units, a discharge switch, off-holding switches, and a drive control unit. The drive control unit selects, as target switches to be driven to be turned on, at least two switches among the switches. The at least two switches include a first switch and a second switch. The first switch is last to be switched to an off-state among the at least two switches that are selected as the target switches and switched to an on-state. The second switch is other than the first switch among the at least two switches. The off-holding switches includes a first off-holding switch and a second off-holding switch. After switching the second off-holding switch to an on-state, the drive control unit switches the discharge switch to an on-state.

  • Patent number: 10295351
    Abstract: A map difference data delivery system includes a map difference data delivery device and a map data holding device. The map difference data delivery device stores map difference data representing a difference between before and after version update and delivers the map difference data. The map difference data includes map elements updated in the version update and dependent map elements by dating back to update of map elements corresponding to a different version. The dependent map elements are map elements that have a dependent relationship and need to be previously updated to avoid conflict with other map elements when updated. The map difference data delivery device groups data of the dependent map elements that have a dependent relationship in the same version.

  • Publication number: 20190009321
    Abstract: The invention provides manufacturing a press formed product with high corrosion resistance and different tensile strengths depending on regions by a small number of processes. The whole of a steel plate having an aluminum-based plating film is heated to an austenite range temperature by a furnace, so that the body of the steel plate is transformed into austenite and a Fe—Al alloy layer is formed on the surface of the steel plate. The steel plate formed with the Fe—Al alloy layer is taken out from the furnace, a first region of the steel plate is heat-retained by a heat resistant and retaining member, and a second region of the steel plate is cooled naturally. When the temperature of the second region becomes lower than a ferrite transformation start temperature, hot press forming is performed to the steel plate to form a press formed product.
