  • Publication number: 20130255615
    Abstract: To suppress current fluctuations upon commencement of driving and prolong lifespan by reducing electric stress caused by current fluctuations. A glow plug 1, a glow switch 2, and a stabilizing coil 3 are series-connected, and upon commencement of the driving of the glow plug 1, a repetition frequency of PWM signals that control the opening and closing of the glow switch 2 is made into a higher frequency than a repetition frequency in a normal drive state and the opening and closing of the glow switch 2 is controlled (S104), and when a predetermined drive shift condition has been met (S106), the repetition frequency of the PWM signals is returned to the frequency during normal driving and the opening and closing of the glow switch 2 is controlled (S108), whereby the current upon commencement of driving is smoothed and the occurrence of an instantaneous large current is suppressed.

  • Patent number: 8422098
    Abstract: A document data capturing device includes a sheet supply tray for carrying documents, a sheet discharge tray located below the sheet supply tray, and a document conveying mechanism including a conveying path along which documents are guided from the sheet supply tray to the sheet discharge tray. The document data capturing device includes a first data-capturing unit and a second data-capturing unit which scan respective sides of a document conveyed by the document conveying mechanism. The first data-capturing unit and the second data-capturing unit are each configured with a reduction-optics scanning mechanism. The conveying path along which a document to be scanned by the first and second scanning mechanisms is conveyed is formed to surround the second reduction-optics data-capturing unit. Thus, the device can be made compact.

  • Patent number: 7783422
    Abstract: A navigation device includes a position detector, a controller, a display portion, an imaging portion and an image processor. The imaging portion images a forward view in front of the vehicle as a forward image from a predetermined distance before a guidance point. The image processor extracts and analyzes visual information of an on-road object from the forward image. The controller specifies a position of the on-road object based on the visual information and map information. The display portion displays and highlights an image of the on-road object at a true position in a road map image, when the position of the on-road object corresponds to the guidance point.
