  • Publication number: 20070102207
    Abstract: A hybrid vehicle drive control system is configured to perform engine startup when switching from an electric drive mode to a hybrid drive mode, without creating a sense of output torque loss. In particular, a controller selectively controls a first clutch disposed between the engine and the motor/generator and a second clutch disposed between the motor/generator and a drive wheel to switch between an electric drive mode in which the first clutch is released and the second clutch is engaged, and a hybrid drive mode in which both the first and second clutches are engaged. The controller sets the second torque transfer capacity to a value that is more than zero and less than the target motor/generator torque of the motor/generator when switching from the electric drive mode to the hybrid drive mode and when starting the engine.

  • Publication number: 20070102205
    Abstract: A hybrid vehicle control system is configured to improve fuel economy by optimizing a torque transfer capacity of a clutch transmitting drive power from both an engine and a motor/generator while the motor torque provides at least part of the drive force. In particular, the system selectively controls a pair of clutches to switch between an electric drive mode and a hybrid drive mode. The torque transfer capacity of the clutch transmitting drive power from both the engine and the motor/generator to a drive wheel includes a motor/generator torque component and an engine torque component. The motor/generator torque component is determined based on a motor/generator torque and a torque transfer capacity margin allowance for the motor/generator torque. The engine torque component is determined based on an engine torque and a torque transfer capacity margin allowance for the engine torque when the drive wheel is driven at least by the motor/generator.

  • Publication number: 20070056784
    Abstract: An engine of a hybrid vehicle is lift started by reducing a rotational speed of a motor/generator of the hybrid vehicle by adjusting a gearshift ratio of a transmission coupled to the motor/generator, and engaging a clutch to couple the engine, while in a stopped state, to the rotating motor/generator for imparting the rotation to the engine.

  • Publication number: 20060276289
    Abstract: A vehicle drive control for a wheeled vehicle including a first motor generator, and a second motor generator. A planetary gear set includes a first rotating element connected to the first motor generator, a second rotating element connected to the second motor generator, and a third rotating element connected to a drive wheel. A rotation control mechanism selectively restricts rotation of one of the first and second rotating elements of the planetary gear set to establish a fixed speed ratio mode, and releases the one of the first and second rotating elements to establish a variable speed ratio mode. A control unit is configured to control each operating state of the rotation control mechanism, the first motor generator, and the second motor generator, and configured to establish the variable speed ratio mode when a slip state of the drive wheel is detected in the fixed speed ratio mode.

  • Patent number: 7040821
    Abstract: A print controller is capable of printing document data within a printable area without generating unnecessary spaces on the sheet, even when the printable area of the sheet has been modified. The print controller includes a function for acquiring the sheet size from the printer driver based on the size set by a sheet size setting function. Specifically, the sheet data acquiring function transmits the sheet size set by the sheet size setting function to the printer driver via a graphics engine. The printer driver calculates the printable area of the sheet based on the sheet size set by the application. The printer driver returns the calculated area to the application. The area returned to the application is then used as a virtual print area used only in processes performed by the application. The print controller has another function for creating a layout based on the virtual print area.

  • Publication number: 20050280396
    Abstract: A state of charge of a battery (1) that drives a motor (6) is computed based on a discharge current measured by a current sensor (3) when the discharge current of the battery (1) does not exceed a rated discharge range of the battery (1). When the discharge current of the battery (1) exceeds the rated discharge range, the state of charge of the battery (1) is computed by estimating the discharge current of the battery (1) from a motor control signal, whereby current changes over a wide range can be found with good precision using the sensor (3), which has a narrow but high resolution measurable range, and the state of charge can be accurately detected.

  • Publication number: 20050062996
    Abstract: In order to transmit fixed-image/text drawing data to print a character contained in a fixed image placed at a predetermined position of paper and body-text drawing data to print a body (text) image in a body, a host apparatus gives the unique download (DL) font ID using a numeric value in different numeric area to each text drawing data stored in external memory attached to a printer. The printer stores the text drawing data identified by the DL font ID in the external memory and upon reception of an image formation command, the printer reads the text drawing data from the external memory and forms an image. Thereby, appropriate text drawing data can be used to print.

  • Publication number: 20050051943
    Abstract: A recording apparatus including an automatic feeding mechanism for picking up one of recording media placed on a feed tray one by one and feeding the recording medium is provided. The automatic feeding mechanism includes: the feed tray on which a predetermined number of recording medium can be placed; a hopper for pushing the recording media on the feed tray toward a feed roller; and a separator located in a downstream of the hopper near the hopper. The automatic feeding mechanism picks up the recording media one by one in an order from an uppermost recording medium to a lowermost recording medium and feeds the recording medium thus picked to its downstream by an action of the feed roller and the hopper to sandwich and transfer the recording medium and a separating action of the separator. The automatic feeding mechanism can be rotated around a fulcrum of rotation so as to be foldable.

  • Patent number: 6493100
    Abstract: When the number of standby time values which exceeds the upper limit, stored in the standby time control section, is determined to be smaller than the predetermined number and the frequency of use of the printer is considered to be middle, the average value of the standby time values is calculated. The average value (time) obtained is subtracted from the sum of the upper limit and the lower limit of the standby time so that the resultant value is set as a sleep time. Thus, the suitable sleep time between the upper limit and the lower limit according to any variable operating condition of the printer can be set.

  • Patent number: 6388760
    Abstract: A host-based printing system in which error conditions are monitored. If a print overrun error occurs, in which the printing speed is faster than the transfer speed, a busy signal is sent to the computer to stop transmission of data for a sufficient amount of time, and the printer is reset. When data transmission from the host computer resumes, data is discarded until the end of the page, allowing the printing process to recover smoothly.

  • Patent number: 6268925
    Abstract: When a printing operation is executed according to an application program, the environment set section 70 of the printer driver is called at a predetermined timing to obtain the information on an output port (S2) and, if the output port is ready (S3: YES) and the data transmission interval between the latest data transmit time set in the data transmit time control section 73 and the present time is more than a reference time (S4, S5: YES), the wake-up command transmission section 72 is caused to transmit an automatic wake-up command to the laser printer 40 during a sleep mode.
