20110118900 | Autonomic Traveling Apparatus for a Vehicle - In an autonomic traveling apparatus for a vehicle, vehicles usually travel an independent travel lane and when there are two approaching vehicles on the independent travel lane, they switch to pass-by lanes to pass by each other. To do this switching operation effectively, respective vehicles check and obtain road conditions around them while they are traveling and the obtained road conditions are transmitted to and collected by a travel administration center so that the road conditions at various points along the lanes can be obtained from the travel administration center. Accordingly, when the autonomic traveling trucks approaching each other and supposed to pass by each other, switch to the associated pass-by lanes, they change travel lanes avoiding the point of bad road condition on the basis of the road conditions sent from the travel administration center. | 05-19-2011 |

20080301263 | Method of Delivering Difference Map Data - The present invention provides, in a car navigation system, a unit of notifying a user of the update contents of map data prior to the downloading of the map data. A vehicle-mounted terminal sets a difference update area in accordance with a selection made by a user and sends a difference update request to a map updating server. If an update mode in this case is “update after outline display”, the vehicle-mounted terminal downloads an outline update map from the map updating server. The outline update map is displayed on a display unit of a display. Here, when a download start button displayed on the display unit is depressed, the vehicle-mounted terminal downloads a detailed update map from the map updating server. The detailed update map is then displayed on the display unit of the display. Furthermore, an updating process is performed on the map data stored in a terminal DB. | 12-04-2008 |

20110310159 | INKJET APPARATUS AND METHOD OF JUDGING REPLACEMENT TIMING FOR COMPONENTS OF THE APPARATUS - In an inkjet apparatus using an inkjet head ejecting multiple types of inks different in viscosity after evaporation of solvent, a replacement timing for a component is judged by using a consumption amount of each type of ink and a generation rate in amount of ink droplets. Accordingly, in the case of using a large amount of ink strongly susceptible to fixed adhesion and increase in viscosity, the component is replaced at an earlier timing, which prevents fixed adhesion from influencing the print performance and the printing apparatus main body. By contrast, in the case of using a large amount of ink less susceptible to fixed adhesion and increase in viscosity, the component is replaced at a later timing and thus can be used until reaching its lifetime. | 12-22-2011 |
20110310160 | INKJET APPARATUS AND METHOD FOR JUDGING REPLACEMENT TIMING FOR COMPONENTS OF THE APPARATUS - In an inkjet apparatus capable of ejecting an ink and a treatment liquid for insolubilizing or coagulating a color material in the ink, a replacement timing for a component of the apparatus is judged based on both the consumption amounts of the ink and treatment liquid measured when the two are consumed together and the consumption amount of the ink measured when the ink is consumed alone. Thus, the component is replaced at an earlier timing when the influence of fixed adhesion is great due to frequent ejection of both of the ink and treatment liquid, which prevents fixed adhesion from influencing the print performance and the printing apparatus main body. By contrast, when the fixed adhesion slowly develops because of less-frequent ejection of both of the ink and treatment liquid, the component is replaced at a later timing and thus can be used until reaching its lifetime. | 12-22-2011 |
20120026230 | INKJET PRINTING APPARATUS - This invention prevents a possible color mixing, that may occur more than a predetermined time after the wiping operation, by executing a pre-printing cleaning ejection while at the same time minimizing the amount of waste ink produced by the cleaning ejection. To this end, if a color mixing is determined as being likely to occur an elapsed time after the previous wiping operation, the pre-printing cleaning ejection uses a second ink volume U, which represents both the color mixing elimination ink volume and the ejection failure elimination ink volume. If it is decided that there is no likelihood of the color mixing occurring the elapsed time after the wiping operation, the pre-printing cleaning ejection uses the first ink volume D which represents only the ejection failure elimination ink volume. | 02-02-2012 |
