  • Patent number: 11964527
    Abstract: A vehicle stabilizer system, including: a stabilizer device and a switching mechanism to switch a roll suppressing function by a stabilizer bar between an effective state in which the roll suppressing function is rendered effective and an ineffective state in which the roll suppressing function is rendered ineffective; and a controller configured to determine whether a lateral acceleration of a vehicle body is greater than a threshold lateral acceleration and control the switching mechanism to render the roll suppressing function effective when the lateral acceleration is greater than the threshold lateral acceleration and ineffective when the lateral acceleration is not greater than the threshold lateral acceleration, wherein the controller employs, as a determination lateral acceleration for determining whether the lateral acceleration is greater than the threshold lateral acceleration, a smaller one of an actual lateral acceleration and an estimated lateral acceleration estimated based on a turning degree

  • Patent number: 11718141
    Abstract: In each of a first stabilizer device and a second stabilizer device, a stabilizer bar is supported by one or more cylinders, a communication passage via which two fluid chambers of each cylinder are connected is provided, and an opening-closing valve is disposed in the communication passage such that an inter-fluid-chamber communication state where the two fluid chambers communicate with each other and an inter-fluid-chamber shutoff state where the two fluid chambers are shut off from each other are selectively established. Hereby, a vehicle body roll restraining effect is achieved in the inter-fluid-chamber shutoff state while the vehicle body roll restraining effect is cancelled in the inter-fluid-chamber communication state. A linkage mechanism by which those two states of each of the stabilizer devices are changed in conjunction with each other is provided.

  • Patent number: 11364763
    Abstract: The ECU of the stabilizer control apparatus determines, based on a high frequency component of a wheel acceleration and a low frequency component of a wheel speed difference, whether a road surface state is a rough road state or a smooth road state. When the road surface state is determined to be the rough road state, the ECU sets a turning determination threshold to a rough road threshold. When the road surface state is determined to be the smooth road state, the ECU sets the threshold to a smooth road threshold. When a turning determination parameter is greater than the threshold, the ECU sets each of first, second, and third cylinders to a lock state to increase rigidity of stabilizers. When the turning determination parameter is smaller than the turning determination threshold, the ECU sets each of the cylinders to a free state to decrease the rigidity of the stabilizers.

  • Patent number: 7800770
    Abstract: When performing Push-type data transfer from the side of an image-supply apparatus 100 to a printer 200P, it is necessary for the printer 200P to have a buffer that is capable of containing at least the capacity for one page of data. Therefore, the text/image-supply apparatus 100 stores printing-description data obtained from the application on its own memory unit 105. The image-formation apparatus 200 performs rasterization based on received printing-description data, however, in this process, when there is a link file L that is linked to the top file T of the printing-description data, the image-formation apparatus 200 specifies the link destination and sends a data-acquisition request to the text/image-supply apparatus 100, so there is no need for a buffer.

  • Patent number: 7697152
    Abstract: In a print system, without requiring a standardized command indicating use of a thumbnail image, and without causing an abnormal operation, a print content transmission device directs a print device to use the thumbnail image, wherein print content is described using XML format, and a direction command is described using XML format in the print content. Specifically, in a step S201, a processing control unit (111) proceeds to a step S202 in the case where there is input from a user I/F unit. In the step S202, a unique information addition unit (104) judges whether or not the thumbnail image should be used for printing. In the case where it is judged that the thumbnail image should be used (S202: Yes), the unique information addition unit (104) directs a print content generation unit (108) to add, to the print content, a direction to use the thumbnail image (step S203).

  • Patent number: 7557951
    Abstract: The description interpreting unit (101) identifies the format (the Exif, the JFIF and the like) of the image data which is included in the content which is received from the host equipment (10). The image data obtaining unit (103) obtains the image data which is linked to the content from the printing content buffer (102) or the external DB (119). The image judging unit (104) judges the type of the received image file, and notifies the result to the image rasterization unit (105). The image rasterization unit (105) extends the compressed image data. The image processing deciding unit (106) decides parameters for the image processing which is executed by the image processing unit (107). The rendering unit (108) converts the image data to be described by the CMYK color space in order to execute printing. And, the printing unit (109) executes printing.

  • Patent number: 7502136
    Abstract: A digital copying machine comprising an image scanner part for reading an original image to reproduce image data of the original image, a laser printer part for printing an image according to given image data, a removable memory card, and a reader/writer of the memory card is provided. For offline print, the image data of a document prepared in an external computer and output control data are stored into the memory card. By installing this memory card in the digital copying machine, the digital copying machine prints the image data read out from the memory card offline in a desired output form. For offline image input, read control data obtained by using an image scanner such as a read gradation level, a read size, density, and the degree of edge enhancement is stored in the removable memory card using software executed in an external computer.

  • Patent number: 7471402
    Abstract: A printing apparatus generates print data with a priority given to a processing speed over a quality of images, even without explicit instructions, when printing images which do not require a high quality. The printing apparatus includes a priority decision unit for deciding whether to prioritize a speed of processing the image data or a quality of the images at the time of printing, based on print content description data including information on layout instructions for printing the images. The printing apparatus also includes a print data generation unit for generating print data including the images, based on the print content description data, the decision made by the priority decision unit, and the image data, and a print unit for printing the print data generated by the print data generation unit.

  • Patent number: 7423776
    Abstract: An image output apparatus capable of offline printing or displaying image and text data automatically and efficiently to a digital copying machine, a printer, a facsimile, a liquid crystal projector, and a television set. Discrimination is conducted as to whether data in a data file to be printed, which is read out from a memory card by a memory card controller, is color or monochrome image data. As a result of the discrimination, when the data is color image data, print confirmation unit provided in the image output apparatus allows a user to confirm whether or not to print out monochrome image data, which is converted from the color image data by the color/monochrome conversion unit.
