  • Patent number: 11440333
    Abstract: A printing system includes a printing device, a platen roller, a controller, and an interface. The printing device includes a thermal head, a ribbon drive source, and a head drive source. When receiving a print command, the controller executes head movement control for moving the thermal head and ribbon acceleration control for accelerating a transport speed of an ink ribbon to a target speed. After completion of the head movement control and the ribbon acceleration control, the controller is configured to control the thermal head to perform printing on the print medium. At least before receiving the print command, the controller is configured to determine a printable distance over which the print medium is transported from the reception of the print command till the completion of the head movement control and the ribbon acceleration control and outputs the determined printable distance through the interface.

  • Patent number: 11429048
    Abstract: A transmission unit transmits driving force to be supplied from a motor to a roller pair. A switching unit acts on the transmission unit to switch a rotation direction of the roller pair by the driving force between a normal rotation and a reverse rotation. A control unit controls a rotation speed of the motor to convey the sheet at a second conveyance speed in a part of a first time period. The second conveyance speed is lower than a first conveyance speed. The first conveyance speed is a conveyance speed when the sheet is conveyed in the image forming unit. In the first time period the sheet having the image formed on the first surface is conveyed in a first direction. In a second time period the sheet is conveyed in a second direction.

  • Patent number: 11411234
    Abstract: The present disclosure relates to a fuel cell system. In abnormality detection control, a control unit of the fuel cell system obtains a maximum filling pressure that is a maximum value of the pressure in a filling flow path during filling, and determines that both of first and second pressure sensors are normal when the difference between a supply start pressure and the maximum filling pressure is equal to or smaller than a reference value. When this difference is larger than the reference value, the control unit determines that there is a possibility that at least one of the first and second pressure sensors may be abnormal. The supply start pressure is a detection value of the second pressure sensor at the time when supply of fuel gas to a fuel cell is started for the first time after filling of a fuel tank with the fuel gas is finished.

  • Patent number: 11251444
    Abstract: A shutoff valve, a first gas pressure sensor, a pressure reducing valve, a second gas pressure sensor, and a gas supply component are provided, sequentially from a gas tank side, in a gas supply flow channel that extends from the gas tank to a gas consuming component. Besides, a buffer tank is provided, via an on-off valve, in a branch flow channel that branches off from the gas supply flow channel between the pressure reducing valve and the gas supply component. This buffer tank is in a situation where the pressure of the buffer tank is not higher than a consumption prescribed gas pressure. In calibrating the first gas pressure sensor, with the shutoff valve closed and with the on-off valve open, a detection value of the first gas pressure sensor is calibrated through the use of a detection value of the second gas pressure sensor.
