20090150075 | Angular Velocity Correcting Device, Angular Velocity Correcting Method, and Navigation Device - Angular velocity correcting devices, angular velocity correcting methods, and navigation devices are disclosed. In some implementations, a first sensor sensitivity correcting method for considering variation of sensor sensitivity due to an oblique angle of an angular velocity detecting sensor with respect to a horizontal plane and a sensitivity error of the angular velocity detecting sensor and correcting the sensor sensitivity is enabled. A second sensor sensitivity correcting method for considering the variation of the sensor sensitivity due to the oblique angle of the angular velocity detecting sensor with respect to the horizontal plane without considering the sensitivity error and correcting the sensor sensitivity is enabled. The sensitivity error is calculated on the basis of a ratio of the sensor sensitivity obtained by the first sensor sensitivity correcting method to the sensor sensitivity obtained by the second sensor sensitivity correcting method. The angular velocity from the angular velocity detecting sensor using the sensitivity error is corrected. | 06-11-2009 |

20080316060 | Navigation Device - The present invention provides a navigation device in which the accuracy of placement of a displayed vehicle position mark is improved at an intersection with a small angle. The navigation device weights coefficients of road candidates for consistent matching, in determining the optimal road from a plurality of matching road candidates. Accordingly, a fluctuating display of the vehicle position mark on an incorrect road at an intersection with a small angle is prevented. | 12-25-2008 |

20150361142 | VACCINE FOR PREVENTING PORCINE EDEMA DISEASE - A purpose is to provide a vaccine which can prevent porcine edema disease in farms where porcine edema disease is anticipated. Meeting this purpose is a vaccine that is a fusion protein in which Stx2eB and a polypeptide having a coiled-coil forming unit are joined or a multimer of the fusion protein, and by immunizing pigs with this vaccine, it is possible to induce potent neutralizing antibodies and to defend against the onset of porcine edema disease. | 12-17-2015 |
