  • Patent number: 10668717
    Abstract: An object of the present invention is to quickly correct a temperature sensor for an ejection head by, both efficiently and in a brief time, estimating a detected temperature of the temperature sensor for the ejection head in a case where the temperature of the ejection head of liquid becomes sufficiently close to an environment temperature. The temperature of a print head 1 is detected by a diode sensor 17 and the environment temperature is detected by a thermistor 10. Based on a change in the detected temperature of the diode sensor 17 at the time of filling of ink for the print head 1, the detected temperature of the diode sensor 17 in a case where the temperature of the print head 1 becomes close to the environment temperature is estimated as an estimated detected temperature. Based on a difference between the estimated detected temperature and the environment temperature, a correction value of the detected temperature of the diode sensor 17 is set.

  • Patent number: 10669112
    Abstract: To control a winding drive current of a motor based on a command phase representing a target phase of a rotor of the motor, a motor control apparatus includes a filter circuit, a phase determiner, and a controller. A current value of the drive current flowing through the winding is obtained at a predetermined period. The filter circuit reduces a harmonic component in a fundamental frequency of the drive current included in a signal indicated by the obtained current value. The phase determiner determines a rotation phase of the rotor based on a filter processed signal. The controller controls the winding drive current to reduce a deviation between the command phase and the determined rotation phase. The filter circuit reduces a harmonic component from a signal indicated by current values of which a number is not greater than a number of the current values obtained at the predetermined period.

The pretreatment composition includes a polymerizable component. Discrete imprint resist portions are disposed on the pretreatment coating, with each discrete portion of the imprint resist covering a target area of the substrate. A composite polymerizable coating is formed on the substrate as each discrete portion of the imprint resist spreads beyond its target area. The composite polymerizable coating includes a mixture of the pretreatment composition and the imprint resist. The composite polymerizable coating is contacted with a template, and is polymerized to yield a composite polymeric layer on the substrate.
