  • Publication number: 20160311224
    Abstract: A wall-shaped enclosure that forms a space which can accommodate a head chip is formed in a projecting manner at a lower end of a lower case member. Since a cylindrical thick part is formed at the lower end of the lower case member, the lower case member is unlikely to be bent, particularly around the wall-shaped enclosure and a part where the wall-shaped enclosure is disposed. The head chip that is disposed in the space of the lower case member which is unlikely to be bent is unlikely to be subjected to an external force, and the cover member absorbs torsion generated between the head chip and the lower case member so that the head chip is even more unlikely to be subjected to the external force.

  • Publication number: 20160261215
    Abstract: A first calculation unit subtracts third digital data which indicates the minimum value of the duty ratio from first digital data which indicates the duty ratio of the PWM driving operation. A slope calculation unit generates slope data which is dependent on the temperature based upon second digital data which indicates the temperature. A second calculation unit multiplies the slope data by the output data of the first calculation unit. A third calculation unit sums the output data of the second calculation unit and the third digital data. A selector receives the output data of the third calculation unit and the third digital data, selects one data that corresponds to the sign of the output data of the first calculation unit, and outputs the data thus selected as a duty ratio control signal.
