It is intended to carry out a focusing operation suitably in each case of automatic focusing and manual focus adjustment. Therefore, in the present invention, there is provided a first focus ring 1 movable between a first position and a second position on an optical axis. Further, a first rotation-angle detection unit detecting a rotation amount of the first focus ring 1 at the first position, a second focus ring 2 coupled to the first focus ring 1 when the first focus ring 1 is at the first position, and a second rotation-angle detection unit detecting a rotation amount of the second focus ring 2 are provided. When the first focus ring 1 is at the first position, a focus lens is driven based on the rotation amount detected by the first rotation-angle detection unit, and when the first focus ring 1 is at the second position, the focus lens is driven based on the rotation amount detected by the second rotation-angle detection unit.
摘要:
An image capture apparatus is provided. The image capture apparatus includes a prism that separates light incident through a lens into at least two color components of light to be output and an image capture device that converts light separated by and output from the prism into a captured image signal. The image capture apparatus includes a fixing plate attached to the image capture device mounted on a substrate. In addition, the image capture apparatus includes a plurality of fixing members for fixing an unattached surface of the fixing plate, which is unattached to the image capture device, on a side surface of the prism through an adhesive.

In a casing of a hydraulic machine of the type comprising a stay ring including a pair of opposing annular plates and a plurality of stay vanes fixed therebetween to form stay vane flow passages between the stay vanes, and a spiral case disposed on the radially outside of the stay ring, the stay vane passages and the spiral case are proportioned such that the ratio n of the area 2.pi. R.sub.o B of a circle encircling the outer periphery of the stay vanes and the cross-sectional area .pi. R.sub.s.sup.2 of the flow passage in the spiral case is from 1.9 to 2.5, and that the ratio (R-R.sub.o) /R.sub.s =l is larger than 0.75 where R.sub.s represents the radius of the cross-section of the flow passage in the spiral case taken along a plane containing the axis of the shaft of the hydraulic machine and intersecting at right angles with the axis of an inlet to the spiral case, R the distance between the axis of the shaft and the center of the flow passage in the spiral case, R.sub.o the radius of the stay vanes to the outer periphery thereof, and B the height of the stay vane flow passages at the periphery of the stay vanes.
摘要:
An imaging block includes a prism, first and second imaging devices, an analog/digital convertor, a timing generator, and first, second, third circuit boards. The prism separates light incident through a lens into at least two colors and outputs the light. The first and second imaging devices are each generates a video signal by photoelectrically converting the light. The analog/digital converter converts the video signal output from each of the devices into a digital signal. The timing generator generates a video-signal processing clock for driving the first imaging device, the second imaging device, and the analog/digital converter. The first imaging device is mounted on the first circuit board. The analog/digital converter and the timing generator are mounted on the second circuit board. The second imaging device is mounted on third circuit board and connected to both the first circuit board and the second circuit board through a cable.
