  • Publication number: 20200079079
    Abstract: An integrated circuit device includes a terminal, a switch circuit, an amplifier circuit, a voltage boosting circuit, and a control circuit. The terminal is connected to a driving signal line of a driving circuit that drives an actuator of a liquid droplet ejection head. One end of the switch circuit is connected to the terminal. The amplifier circuit receives an output signal from the other end of the switch circuit, and amplifies an induced voltage of the actuator after the actuator having been driven. The voltage boosting circuit generates a boosted voltage for level-shifting a switching signal of the switch circuit based on the step-up clock signal.

  • Publication number: 20190137903
    Abstract: In a cleaning roller, a plurality of uneven portions are formed on a surface. A rotation shaft of the cleaning roller is inserted into a cylindrical hole of a cylindrical cleaning member in which the plurality of uneven portions are formed, and the clean member and a rotation shaft are fixed in a state where the cleaning member is twisted in a circumferential direction. The cleaning member, in which the plurality of uneven portions extending so as to twist in the circumferential direction are formed, is molded by rotating an extrusion molding die while extruding an extrusion molding material toward an extrusion molding hole of the extrusion molding die. An injection molding material with which the injection molding die is filled is solidified to mold the cleaning member and the cleaning member is stripped from the injection molding die by rotating the extrusion molding die around an axis.

  • Patent number: 8892337
    Abstract: An apparatus for detecting imbalance abnormality in an air-fuel ratio between cylinders in a multi-cylinder internal combustion engine according to the present invention increases a fuel injection quantity to a predetermined target cylinder to detect imbalance abnormality in an air-fuel ratio between cylinders at least based upon a rotation variation of the target cylinder after increasing the fuel injection quantity. The increase in the fuel injection quantity is carried out in the middle of performing the post-fuel-cut rich control. Since timing of the post-fuel cut rich control is used to increase the fuel injection quantity, the exhaust emission deterioration due to abnormality detection execution can be prevented as much as possible.
