Patents by Inventor Teruki Kurashina

Teruki Kurashina has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9469102
    Abstract: A printing apparatus includes: a printing unit that performs printing on a printing medium; a drive unit that causes the printing unit to move; a power supply unit that supplies power to the drive unit; a detection unit that detects the movement of the printing unit; and a controller that controls an initialization operation related to the printing unit based on a detection result of the detection unit. When power supply from the power supply unit to the drive unit is started, the controller acquires the detection result obtained when power is not supplied, performs the initialization operation in a case where a movement of the printing unit is detected in the detection result, and does not perform the initialization operation in a case where a movement of the printing unit is not detected in the detection result.

  • Patent number: 8328308
    Abstract: Disclosed is a fluid ejecting apparatus including a fluid ejecting head that ejects fluid, a waveform generator that transmits a driving waveform for driving the fluid ejecting head to the fluid ejecting head, and a waveform designation signal transmitter that transmits a waveform designation signal for designating a driving waveform to be generated to the waveform generator, wherein the waveform generator transmits the driving waveform at a timing based on a reception timing of the waveform designation signal.

  • Patent number: 6603282
    Abstract: A DC motor control device and a DC motor control method are configured to calculate driving motion time and DC motor current flow per unit time, or DC motor total current flow and driving motion time, every continuous driving motion of the DC motor, and interpose a drive stopping time to stop the DC motor for a time corresponding to the calculated value every time before a subsequent driving motion starts. Alternatively, they are configured to interpose a drive stopping time to stop the DC motor for a time calculated by cumulating such time corresponding to the calculated value over a plurality of occurrences every time before a subsequent block of driving motions starts after each block of driving motions.
