摘要： A measurement pattern is moved on a display, and an image of the measurement pattern is captured by making a visual field of an image sensor follow the scroll of the measurement pattern. On the basis of the captured image, a motion picture response curve is obtained. Then, the motion picture response curve is transformed into an MTF (modulation transfer function). A normalized spatial frequency value N_Sf(a %) at which an MTF value starts declining by a predetermined percentage from a highest luminance portion of the MTF is determined. Then, the motion image quality of the display is evaluated on the basis of the normalized spatial frequency value N_Sf(a %). Thus, the evaluation of the motion image quality of the display can be achieved on the basis of an intuitively understandable motion image quality evaluation index.

摘要： A test pattern is moved on a screen 5 subject to measurement with the field of view of an image sensor pursuing the motion of the test pattern so as to observe BEW. Subsequently, the field of view 33 of the image sensor is moved at the same velocity vc as in the foregoing observation to capture an image of a static pattern PE, and a blur width W along the scrolling direction that appears in a distribution profile of the captured image is observed. Based upon the blur width W and the exposure time of the image sensor for capturing the image of the static pattern PE, the moving velocity of the test pattern at the time of observation of the BEW is estimated, and by using the moving velocity, the BEW is normalized. Evaluation of the moving image quality of the screen is carried out by using the normalized N BEW. The moving velocity of the original test pattern can thus be estimated easily and accurately, and accordingly, the moving image quality of the screen can be evaluated accurately.

摘要： In a power steering apparatus for a small vessel, an electrically driven assist device (26) and a helm pump (27) formed of a swash plate type axial piston pump are arranged in parallel on a common base (28). The electrically driven assist device (26) and the helm pump 27 are connected through a transmission system (34) under the common base 28 and integrated into a steering oil pressure generating unit (6) functioning as the power steering apparatus. The electrically driven assist device (26) is carried on an instrument panel (3). The parallel arrangement of the electrically driven assist device (26) and the helm pump (27) allows the steering oil pressure generating device (6) to be reduced in vertical length, so that it is possible to shorten the distance between the instrument panel (3) and a bottom (2) of the vessel and to lower positions of a handle and an operator's seat, thereby realizing the low center of gravity.

摘要： Impurity is removed from gas, the resultant gas is introduced into a cell 15, and the intensity of light transmitted through the cell 15 is measured as a reference. Gas containing impurity of which concentration is known, is introduced into the cell 15, and the intensity of light transmitted through the cell 15 is measured with the temperature and pressure maintained at those used at the measurement of the reference light intensity. Then, the absorbance of the impurity is obtained according to the ratio of the two light intensity data obtained by the two measurements above-mentioned. The impurity absorbance thus obtained is stored, in a memory 20a, as a function of an impurity concentration. Gas containing impurity of which concentration is unknown, is introduced into the cell 15, and the intensity of light transmitted through the cell 15 is measured with the temperature and pressure maintained at those used at the measurements above-mentioned. The absorbance of the impurity is obtained according to the last-measured light intensity and the reference light intensity. The absorbance thus obtained is applied to the function, thereby to obtain the impurity concentration.
