  • Patent number: 10336096
    Abstract: Provided is a printing apparatus which includes a thermal head having a plurality of heat generation elements whose temperatures are controlled by applying a voltage and performing printing on a printing medium and a head drive circuit being supplied periodically with a control signal and print data to control application of a voltage to each of the plurality of heat generation elements. One period of the control signal includes first and second voltage application control periods which are separated from each other. The first voltage application control period is a period in which the printing is performed by controlling the application of a voltage, and the second voltage application control period is a period in which the printing is not performed and a temperature of the thermal head is adjusted by controlling the application of a voltage.

  • Publication number: 20190139744
    Abstract: A controller disclosed herein drives, in a first step, a high frequency generating source at a first energy condition, and drives, in a second step, a high frequency generating source at a second energy condition. Prior to a switching time of the first step and the second step, the controller switches gas species supplied from the gas supply system into the processing container, and sets a gas flow rate in an initial period just after the switching to be larger than a gas flow rate in a stabilization period after lapse of the initial period.

  • Patent number: 8942507
    Abstract: The signal processing method of the present invention produces interpolated signal values in an image signal by an inverse discrete cosine transformation with a set of frequency coefficients by decreasing an interval for reproduction of pixel signal values, wherein a set of frequency coefficients is provided by a discrete cosine transformation and is compensated for the frequency response caused by dividing pixels. According to the invention, an image signal similar to that obtained with a solid-state imaging device constructed by divided pixels is provided. Hence, even when the number of horizontal pixels and/or the number of vertical pixels of the solid-state imaging device are a half of that of a display apparatus used, an image signal suitable to the display apparatus can be produced.
