An imaging device that includes a plurality of lens portions, a plurality of imaging regions each including a light receiving surface that is substantially perpendicular to the optical axis direction of each of the lens portions, and outputting an imaging signal, and a parallax computing portion that uses any one of the plurality of imaging signal as a reference imaging signal (G0), and computes a parallax amount of other imaging signals relative to the reference imaging signal (G0), wherein a composite image is generated by correcting and combining the plurality of imaging signals based on an effective pixel signal obtained by deleting a pixel signal obtained from pixels of a region (d min x in the x direction, d min y in the y direction) that may contain image omission resulting from parallax in the imaging signal other than the reference imaging signal (G0), and on the parallax amount.

    摘要: In a cooling device including a pump, a heat absorber, a heat radiator, a flow channel that allows communication between interiors thereof and forms a closed-loop circulating cycle therebetween, and a liquid refrigerant that circulates in the flow channel, a volume of a gas generated in the liquid refrigerant owing to temperature change within an operating temperature range of the liquid refrigerant is smaller than a volume of a sphere that is inscribed in a cross-section of the flow channel. In this way, even when the solubility changes due to rapid heating or cooling of the liquid refrigerant, no gas is generated in the liquid refrigerant. Thus, it is possible to provide a cooling device that maintains an excellent cooling effect even after a long time use.

    摘要: The present invention relates to a method for driving an ultrasonic motor of the type which includes a vibrator for causing a flexural vibration wave in response to a pair of AC driving voltage signals, and a rotor in contact with the vibrator and moved by the flexural vibration wave. The rotational speed of the ultrasonic motor is controlled by using a feedback signal and a data table, the feedback signal indicating the current rotational speed of the ultrasonic motor, and the data table storing values of the feedback signal as a standard function of the rotational 21 speed. The method includes the step of sampling the feedback signal and detecting the rotational speed in a plurality of rotation states of the ultrasonic motor. The method obtains an approximate function representing the relationship between the sampled feedback signal and the detected rotational speed of the ultrasonic motor, and calculates correction coefficients for adjusting the approximate function to the standard function. The method then controls the rotational speed of the ultrasonic motor by using the feedback signal. In the controlling step, the method corrects the feedback signal obtained from the ultrasonic motor by using the correction coefficient, whereby a value of the approximate function is transformed into a corresponding value of the standard function.
