  • Patent number: 11027564
    Abstract: In a printing apparatus, a controller is configured to control a printing unit such that printing is started after a transport distance of the substrate reaches a pre-discharge transport distance, in which the pre-discharge transport distance is set to a value not less than a first longest distance, provided that a transport distance in a condition in which the transport distance is a longest distance among conditions 1, 2, and 3 provided below is the first longest distance. Condition 1: a transport distance until a region of the substrate that was nipped between a front driving roller and a nip roller passes through a printing head disposed most downstream in a transport path of the substrate, Condition 2: a transport distance until a transport speed of the substrate becomes constant, and Condition 3: a transport distance until tension of the substrate being transported becomes stable.

  • Publication number: 20210156320
    Abstract: An internal-combustion engine includes a variable compression ratio mechanism for changing a mechanical compression ratio, and a variable valve timing mechanism for changing the valve timing of an intake valve. When acceleration is demanded, a target compression ratio is set to a lower compression ratio than the target value in a normal condition, and the valve timing is set to the advance angle side. Since the allowable combustion pressure decreases in a prescribed intermediate compression ratio region, if an actual compression ratio exists in the prescribed intermediate compression ratio region in the course of a compression ratio change accompanying acceleration, the variable compression ratio mechanism restricts the intake pressure by increasing a degree of opening of a wastegate valve or reducing a degree of opening of a throttle valve, for example.
