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.

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.

Abstract: A medical device system that includes an ultrasound transducer and a processor. The ultrasound transducer includes a plurality of electrode plates to which a drive signal is supplied, and a plurality of piezoelectric elements that are alternately arranged with the electrode plates, and that generate ultrasound vibrations according to the drive signal. The ultrasound transducer also includes an electric wiring that electrically connects the electrode plates adjacent to each other, and a memory that stores reference information regarding specific initial characteristics. The processor analyzes the generated ultrasonic vibrations to determine a resonance point of the ultrasound transducer, and detects resonance point information regarding the resonance point. The processor then determines whether an abnormality has occurred in the ultrasound transducer by comparing the stored reference information and the detected resonance point information.
