摘要： A method of driving a thermal printing head includes expanding the printing time for a line which follows successive non-printed (blank) lines. In this manner, deterioration otherwise caused in the print density can be avoided without employing an auxiliary heater for the thermal head. Instead of expanding the printing time, the applied voltage may be increased to achieve the same result.

摘要： A facsimile communication system in which transmission is carried out in such a manner that, when the time of transmission of the video signals of lines provided by scanning an original is shorter than that determined by a facsimile on the signal receiving side, fill bits are transmitted in succession with the video signals so that the time of transmission of each line is adjusted to that determined by the facsimile on the signal receiving side. The period of time required for the facsimile on the signal receiving side to record video signals per line is discriminated by a facsimile on the signal transmitting side for every line according to the contents of video signals. The period of time thus discriminated is utilized as the time of transmission to transmit the video signals for each line.

摘要： A thermal head drive circuit with the input connected to a source of printing data and the output connected to a thermal head including heater elements, so as to improve the printing quality of a thermal head recording apparatus for printing successive lines. Improved printing quality is effected by using data from previously printed lines to compute a corrected pulse energy for the line being printed. The circuit uses a heat accumulation state operator for computing the heat storage state of each of the heater elements constituting a thermal head, a pulse energy operator for computing a printing pulse energy to be applied to each of the heater elements, a memory for storing the electrical pulse energy used in the previously printed line, and either a pulse interval detector for detecting a time interval from a termination of printing of a previously printed line, or a temperature detector for detecting an internal-temperature of a thermal head. The pulse energy operator uses data from the heat accumulation state operator, from the memory which has data on the pulse energy used in previously printed lines, and from either the pulse interval detector or the temperature detector. The output of the pulse energy operator is connected to a pulse applying circuit which is used to drive the heater elements of a thermal head.

摘要： An ink donor sheet comprising a porous sheet and a heat-fusible ink layer formed on it is disclosed. The ink layer has such temperature-dependent gradation characteristics that it remains solid at ordinary temperatures and when it is heated to a certain temperature its viscosity is suddenly decreased and upon further heating, the viscosity is decreased gradually. The ink donor sheet is capable of producing halftones in the images it creates.
