Title: Apparatus for correcting density irregularity of video printer
Inventor: EBINE YOSHIAKI
IPC: B41J2/00
Filed: 1990-01-12
Abstract: PURPOSE:To maintain the heat generating amount at a heat sensitive head to be a predetermined value thereby to reduce the density irregularity in printing by counting the number of data to be written in a line memory, and adding an adding strobe time set corresponding to the counting value to a reference strobe time. CONSTITUTION:A counter part 7 counts the number of data to be transferred and written into a line memory of a printer part 5 from a density-gradation signal converting part 4, with outputting a signal. A controlling part 9 generates a strobe signal every time each gradation data is completely written into the line memory of the printer part 5, and supplies a heating current based on the image data to a corresponding heat sensitive head. The outputting period of time of the strobe signal is equal to the sum of a reference strobe time read from a memory part 8 based on the detection of the gradation (64 gradations) of the gradation-density signal converting part 4 and an adding strobe time for a group of the heat sensitive heads based on the number of data counted from the data written into the line memory. When the controlling part 9 generates the thus-summed strobe signal in accordance with the counting data of the counter part 7, the printing image is corrected.

Abstract: PURPOSE:To provide a method and an apparatus for controlling alternating current motors wherein a speed command is quickly and smoothly given after the end of a momentary power failure until the speed becomes a speed set by a target speed command means. CONSTITUTION:If input to a voltage type inverter is interrupted and then power supply is restored during the regenerative operation of an alternating current motor 4, the rate of change in the output of an output gradually changing means is made higher than that when starting the motor from a standstill.
