摘要:
An automotive constant speed cruise control system for a vehicle includes a controller for automatic speed change for automatically changing over a speed stage in a transmission in accordance with the relationship between a throttle valve opening degree and a car speed; a controller for constant speed traveling having a constant speed traveling control function for operating a car at a target car speed by controlling, based on a duty ratio, the throttle valve opening degree according to the actual car speed and a transmission limiting function for sending out a signal for prohibiting selection of the maximum speed stage in the transmission to the controller for automatic speed change for a specified time when the car speed lowers, and a transmission limiting function capable of being externally started by inputting a speed change signal representing that the transmission has been shifted down from a maximum speed to the controller for constant speed traveling.

An automatic speed control apparatus for controlling the running speed of a vehicle at a constant set speed includes an auxiliary intake passage providing direct communication between portions of a main intake passage upstream and downstream from a throttle valve so as to bypass the throttle valve, an auxiliary intake air valve adapted for controlling the flow rate of air in the auxiliary intake passage, and a fuel supply cut-off means for suspending the supply of fuel to the engine from a moment at which a fuel supply cut-off condition is met, which requires the throttle valve to be set at the minimum opening position and the engine speed to be higher than a predetermined fuel supply cut-off engine speed, until the moment at which a predetermined fuel supply recovery condition is met. An actuator for actuating the throttle valve is controlled so as to vary the degree of opening degree of the throttle valve and enable the vehicle to run at the constant set speed. The auxiliary intake air valve is controlled in such a manner that the flow rate of air in the auxiliary intake passage is reduced before the fuel supply cut-off condition is met during motion of the vehicle under the control of the automatic driving apparatus. The rate of fuel supply to the engine has therefore been reduced before the fuel supply is actually cut-off so that the amount of change in the engine output torque and, hence, the level of shock produced by the change in the engine output torque are reduced when cut-off of the fuel supply is executed.
摘要:
A constant-speed control device for a vehicle including a fuel cut device and a suspending device which suspends a fuel cut operation. An actuator is provided for controlling a throttle valve so that the vehicle runs at a constant speed. The fuel cut device carries out a fuel cut when the degree of opening of the throttle valve is smaller than a predetermined value. The suspending device suspends operation of the fuel cut device until the vehicle speed becomes higher than a target value by a predetermined value.

An apparatus for preparing a two-dimensional color code includes a reading section for reading an original image object to output to processing device; processing means having a code conversion section to output two-dimensional color codes corresponding to gradations of shades of color separately of CMY colors in original image data of one pixel read; and a printing section for printing on a printing sheet. An apparatus for restoring a two-dimensional color code reads the two-dimensional color code at the reading section to output the gradations of shades of color separately of CMY colors. The printing section prints restored image data on a printing body on the basis of the gradations of shades of color.

An automatic loading disc player includes a turntable for rotating a disc to be played back, a disc transfer mechanism for carrying and transferring the disc into a predetermined playback position on the turntable or a position in the vicinity thereof, and a positioning mechanism for positioning the disc in a predetermined position on the disc transfer mechanism. The positioning mechanism is engageable with at least three points on an outer peripheral edge of the disc for positioning the disc and drivable in coaction with disc transferring operation of the disc transfer mechanism. The positioning mechanism is releasable from engagement with the disc while the disc is being played back. The positioning mechanism includes three positioning levers angularly movable by an endless chain for engagement with the outer peripheral edge of the disc. With this arrangement, the disc can accurately and reliably be positioned on the disc transfer mechanism regardless of the diameter of the disc.
