摘要： In a solid-state imaging device including an analog-to-digital converter, a clock converter that generates a high-speed clock that is faster than a master clock is provided. A voltage comparator compares a pixel signal input from a vertical signal line for each row control line with a reference voltage, generating pulses having magnitudes corresponding to a reset component or a signal component in a temporal direction. A counter counts the width of pulse signals until completion of the comparison in the voltage comparator based on a clock that is generated based on the high-speed clock, holding a count value at a time of completion of the comparison. A communication and timing controller exercises control so that the voltage comparator performs comparison for the reset component and the counter performs down-counting in a first processing iteration and so that the voltage comparator performs comparison for the signal component and the counter performs up-counting in a second processing iteration.

Piping 1 having a fluid-mixing region M includes a reducer 5 including an end portion 5e disposed substantially on a central axis of a main pipe 2. Low-temperature water flows through the reducer 5 at a lower velocity than high-temperature water flowing outside the end portion 5e. The low-temperature water and the high-temperature water have different temperatures. The low-temperature water and the high-temperature water are mixed in the fluid-mixing region M downstream of the reducer 5. The reducer 5 has a weld line 5f formed to connect the end portion 5e and an elbow portion 5d together. The distance between the weld line 5f and a downstream end 5a is equal to or larger than the inner diameter D of the main pipe 2.

The pixel unit includes a plurality of pixels arranged in a matrix form, each pixel including a photoelectric conversion element.
