摘要:
A supercharged engine knock control system of the class in which spark advance is retarded by a retard correction value varying in response to an occurrence of knocking is improved in such a manner that the retard correction value computed under engine conditions which do not accurately reflect the octane rating of the fuel is not taken into account in determining the boost pressure control. To this end, the knock control system comprises a memory for storing predetermined engine load threshold values that vary depending on engine speed. Boost pressure is lowered when the actual engine load is greater than the engine load threshold value and when the retard correction value is greater than a reference value.

A fuel supply system controls the amount of fuel to form a stoichiometric combustible mixture during a normal operating condition of the engine. The mixture is enriched during a transient condition to lower the exhaust gas temperature and to reduce the heat load on the exhaust system. Fuel enrichment is delayed for a delay time which varies depending on the time interval between successive acceleration cycles, to minimize fuel consumption while avoiding overheating of the exhaust system.

A recording device and a control method for a recording device improve the accuracy of reading MICR information while also shortening the time required for recording media processing. A dot impact printer 10 has a magnetic head 34 that magnetically reads MICR information recorded on a recording medium S, a recording head 18 that is mounted on a different carriage than the magnetic head 34 and records images on the recording medium S, and a back scanner 112 that optically reads MICR information recorded on the recording medium S, disposed sequentially to the transportation path P of the recording medium S. When reading the MICR information by means of the magnetic head 34 does not succeed, the recording medium S is conveyed to the back scanner 112, the MICR information is read by the back scanner 112, the reading results are compared, and the MICR information is identified.
摘要:
In a method of processing recording media on which magnetic ink characters are printed, the media is transported at a first speed in an upright position along a transportation path from a supply unit to a discharge unit. The magnetic characters are read and output signals representative of the reading generated. The output signals are analyzed, including comparing the output signals with previously stored signal patterns of magnetic ink characters to determine if the magnetic characters can be recognized or not. The transporting of the recording media is paused, or slowed to a second speed substantially lower than the first speed, for a period of time during the analyzing of the output signals. A processing apparatus includes components for carrying out the operations of such method.

When USB communication between a host computer and media processing device is interrupted while processing media, sending useless read data to the host computer is prevented. A control method for a media processing device 1 that is connected by a USB cable to a host computer 30, reads information continuously from a plurality of slips S according to instructions from the host computer 30, and sends the read information to the host computer 30 has steps of monitoring the communication state between the host computer 30 and the media processing device 1, interrupting the continuous reading process by executing a software reset process when communication becomes disabled while the continuous reading process is running (step S25 returns Yes), and deleting read data that has not been sent to the host computer 30 (step S26).
摘要:
A printer capable of printing to both roll paper and slips. The printer includes a condition setting unit 15 for setting or not setting the absence of roll paper in the printer as a set condition for taking the printer off-line. An off-line status determination circuit 16 for generating an output in response to the set condition of the condition setting unit 15 when the power is turned on or reset, and a print controller responsive to the output from said off-line status determination circuit for determining whether to set the printer to be taken off-line or not according to the set condition of the condition setting unit . Accordingly, when roll paper is not needed, the printer can thus print to slips without ever loading roll paper.
摘要:
A control method for a print media processing apparatus that prints on a print medium based on print data supplied from a host computer, comprising converting the print data supplied from the host computer to the print media processing apparatus before a print command is asserted to print image data in a buffer based on a print data conversion command, and controlling printing in response to a print command by accessing the buffer and retrieving the print image data.

A trapping area creating method in which an image represented in form of a combination of polygons is divided into a plurality of image areas by a straight line passing through vertexes of the polygons. The propriety of trapping is decided for each pair of image areas adjacent to one another in at least one direction of two predetermined directions, with respect to the plurality of image areas wherein the image is divided. A band-shaped trapping area extending along a boundary of two image areas constituting a pair of image areas decided as being suitable for a trapping is created.
