摘要： High print quality from a thermal printer is maintained while the print speed is decreasing without producing white streaks or uneven print density by controlling the hysteresis coefficient of the thermal print head 35 based on the energizing history of the thermal print head 35 and print speed control factors used for determining print speed,which is the speed at which the paper is advanced while printing. The thermal printer, comprises a hysteresis coefficient setting unit 2 for setting a hysteresis coefficient for the print head based on the energizing history of the thermal print head 35; an energizing time calculation unit 3 for calculating the energizing time during which drive signals are to be applied to the thermal print head 35 for printing based upon the hysteresis coefficient set by the hysteresis coefficient setting unit; a printing control device 4 for generating the drive signals to be applied to the print head in response to the energizing time calculated by the energizing time calculation unit 3; a print speed determination unit 5 for determining the change in the print speed and when the print speed is decreasing; and a coefficient changing unit 6 for changing the hysteresis coefficient when a change in print speed occurs causing the print speed to decrease. Preferably the coefficient changing unit changes the hysteresis coefficient to a value greater than the hysteresis coefficient value used immediately before deceleration.

摘要： A thermal printer 1 and control method for controlling print speed to prevent variation in printing pitch due to frequent slight changes in the print speed following a significant change in print speed. The print speed, which is the speed at which the print medium i.e., paper is conveyed when printing, is controlled based on known print speed control factors. The thermal printer comprises a paper feed mechanism for conveying the print medium at a controlled print speed passed a thermal print head, a print speed control unit 9 for controlling the print speed of the paper feed mechanism based on the print speed control factors, a print speed change acquisition unit 3 for determining the change in the print speed over a predetermined time, and a comparison unit 7 for determining if the change in print speed exceeds a predetermined threshold value. The print speed control unit 9 limits change in the print speed based on the print speed control factors for a predetermined time after the comparison unit 7 determines that the change in print speed exceeds the threshold value.

摘要： The valve drive apparatus of the invention comprises an exhaust valve drive mechanism capable of changing an open/close timing of an exhaust valve, and a control device which controls the exhaust valve drive apparatus so as to release the exhaust valve during an intake stroke, independently of an exhaust stroke, in an EGR mode. Preferably, the exhaust valve drive mechanism comprises a first exhaust cam which defines the exhaust valve releasing timing and the amount of valve lift in the exhaust stroke, and a second exhaust cam which defines the exhaust valve releasing timing and the amount of valve lift during the intake stroke. In an normal mode, the displacement of the first exhaust cam is transmitted to the exhaust valve, and in the EGR mode, the displacement of the second exhaust cam is transmitted to the exhaust valve, in addition to the displacement of the first exhaust cam.

摘要： A control method and apparatus for a thermal head capable of printing two colors applies thermal history control using a simple circuit configuration. The thermal head control apparatus has a print data processing unit 40 and a drive control circuit 50. The print data processing unit 40 has a first command processing function for converting first color data to a first and second stage energizing commands, a second command processing function for converting second color data to a second stage energizing command, a first line buffer 43 for storing first stage energizing commands, and a second line buffer 44 for recording second stage energizing commands. The print data processing unit 40 selectively outputs energizing commands from the first line buffer 43 and energizing commands from the second line buffer 44. The drive control circuit 50 has a print buffer 52 and history buffer 53, and energizes the heating elements of the thermal head 10 based on energizing commands determined by a comparison of content stored to the print buffer 52 and history buffer 53.

摘要： A driving unit generates a driving current corresponding to a light generation control signal CTL supplied from a light generation controlling unit. The driving current is supplied to an LED. Light emitted from the LED impinges on a light receiving circuit through a space of a monitoring area. The received light level of the light receiving circuit is converted into a received light level signal RLV in an A/D. The received light level signal RLV is supplied to a smoke detecting unit and the light generation controlling unit. The received light level signal RLV is monitored in a short period by the smoke detecting unit. When the received light level signal RLV is equal to or lower than an alarm level, an alarm signal ALM is output. The light generation controlling unit compares the received light level signal RLV with a reference level in a long period. The light generation control signal CTL is increased or decreased so that the level difference between the received light level signal RLV and the reference level is eliminated.

摘要： An operating system provides extensions through which application developers may extend the capabilities of a shell of the operating system. For example, application developers may add menu items to context menus for objects that are visible within an integrated system name space. In addition, developers may add property sheet pages for such objects. Application developers also have the option of providing per-instance icons for each instance of an object. Application developers may provide data object extension handlers for customizing data sources on a per-object class basis and may provide drop target extension handlers on a per-object class basis to customize drop target behavior. Developers may additionally provide copy-hook handlers to regulate file system operations on objects. Developers may also extend the functionality provided by the shell of the operating system by adding their own custom name spaces to the integrated system name space. The mechanism provided by the operating system to add such a name space is polymorphic and transparent to users.

摘要： A computer system provides expanded clipboard formats that embellish the number of formats that may be used with a clipboard. These expanded clipboard formats enable users in applications to broaden their use of the clipboard and other data transfer mechanisms. The clipboard formats may be utilized by a conventional clipboard, by drag-and-drop mechanisms and by OLE data transfer mechanisms. Certain of the expanded clipboard formats are adapted for use in the data transfer of non-file system objects.
