Title: Plotting control method
IPC: G06T11/00
Filed: 1992-03-16
Abstract: PURPOSE:To improve an efficiency at the time of plotting one part of a graphic within a clipping area. CONSTITUTION:The graphic is divided into several areas according to a prescribed rule by an area dividing part 10. Then, coordinate points to be plotted within one of the divided areas are calculated by a plotting coordinate calculating part 14, and whether or not the obtained coordinate points should be actually plotted is judged by a clipping area judging part 18. Moreover whether or not the next coordinate points should be calculated is judged based on the obtained coordinate points by the next point calculation judging part 20, and when it is not necessary, a processing is transferred to the plotting of the next area. Thus, the processing of searching the coordinate points whose plotting is not necessary by the calculation is omitted, so that the plotting speed can be improved.

Filed: 1983-04-01
Abstract: PURPOSE:To facilitate and ensure sound memory, by displaying an elapsed time and a remaining time by automatically setting a recording time when the recording time is not set by an external switch. CONSTITUTION:Unless a recording time is set by operating an external setting switch 8, a selector 13 selects the recording time due to an internal time setting circuit 12 by the high level output from a latch circuit 15 in a set state to supply the same to a latch circuit 14 and presets the recording time automatically set by an up-down counter 11. When FF7 is triggered in this state by a recording start trigger signal, the counter 7 performs the down-counting of an 1Hz- clock and counts a recording residual time while a counter 5 performing up- counting counts a recording elapsed time and the count contents of the counters 11, 5 are displayed. By this mechanism, sound memory in an electronic clock with sound memory function is easily certainly performed.

Abstract: PURPOSE:To level of a toner layer adhered to a toner carrier to a uniform layer so that an image having high resolution is obtd. by providing a bias member for stripping the toner adhering to the outside of the toner layer. CONSTITUTION:Coulomb force is formed between the negative potential of the toner T on the side outer than the toner T of a single layer in a uniform state and the positive potential of a bias roller 16 on the surface of a carrier transfer layer 38 when the part of the toner layer adhering to the surface of the carrier transfer layer 38 of an OPC belt 21 in the part of a developing device 27 arrives at the position of an adhered toner layer controller 15. The toner T on the side outer than the single layer is then attracted to the roller 16 and is stripped from the surface of the carrier transfer layer 38. The toner layer consisting of only the single layer is formed on the surface of the carrier transfer layer 38 past the adhered toner layer controller 15 part. On the other hand, the toner T attracted on the surface of the roller 16 is removed from the roller 16 by a toner removing blade 18 and is housed into a toner receiver 17. The toner layer to be adhered to the toner carrier is thereby made into the uniform layer of the single or plural layers.
