  • Publication number: 20060058959
    Abstract: A communication control device for passenger protection device includes a satellite sensor unit and an ECU being connected to the satellite sensor unit via a communication line. The satellite sensor unit includes a satellite sensor main body, which detects an impact against a vehicle, and a controller, which obtains a measurement from a signal detected by the satellite sensor main body. The ECU includes a main controller which determines deployment of a passenger protection device. The controller of the satellite sensor unit is adapted to compares the measurement or a calculated value which is calculated based on the measurement with a preset reference value range, and, when the measurement or the calculated value is within the reference value range, the controller transmits a communication from the satellite sensor unit to the ECU at an interval which is longer than a predetermined time interval.

  • Patent number: 7003237
    Abstract: Image formation condition is available, which hardly causes imperfections of the image quality. A full-color image formation system selects plural secondary transfer conditions in a secondary transfer unit within a specific range, forms test charts according to each of the secondary transfer conditions selected, and prints them out. A user checks by viewing the test charts printed on each recording sheet, and selects a page number of the sheet where the user evaluated an image quality as the best; and the image formation system sets the secondary transfer condition for the sheet as a standard secondary transfer condition thereafter.

  • Patent number: 6973272
    Abstract: The present invention enables registration adjustments during actual use of an image forming apparatus. A test pattern is formed on a sheet in a full-color image forming apparatus and the test pattern formed on the sheet is read in an image read unit. From the result of reading the test pattern, misregistrations of vertical and horizontal scaling factors, parallelism, squareness, skew, side registration, and lead registration in the test pattern are determined, and mounting positions, drive timings, drive speeds, and the like of constituent members are adjusted.

  • Publication number: 20050158695
    Abstract: In a tactile display apparatus which displays image information as differences in elevation created among tactile pins which are disposed crisscross in a matrix arrangement, a fewer number of solenoids are used which make the tactile pins project and retract, the number of components is accordingly reduced and the crisscross adjacent gaps between the tactile pins are narrow. Since the solenoids 4 which make the tactile pins 10 project and retract are disposed in a row vertically, one for every preset number of the tactile pins which are lined up in the vertical direction, to a movable unit 5 which is capable of freely moving in the vertical direction and the horizontal direction along which the tactile pins are disposed, and since the movable unit repeatedly moves along the vertical direction and the horizontal direction in turn, the solenoids make all tactile pins project and retract.
