摘要:
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.

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.

A diving bell type control rod of sodium bond type. The control rod including a plurality of control elements each comprising a pellet chamber for packing B.sub.4 C pellets and disposed in a cladding tube, an intermediate plug disposed above the pellet chamber, an upper chamber formed above the intermediate plug, a vent tube allowing the pellet chamber to communicate with the upper chamber while penetrating through the intermediate plug, upper and lower vent holes formed in upper and lower two stages in the cladding tube at the upper chamber, a sodium inflow port opening to the upper surface of the intermediate plug, and a sodium introduction tube extending from the sodium inflow port to a position below the lower end surface of the intermediate plug while penetrating through the intermediate plug.
摘要:
An image reading device for reading an image by a solid-state image reading elements (CCDs) being disposed at the image forming point of an optical unit which is integrated with at least an image forming lens, dichroic mirror for separating the color image into plural color components and unit construction parts such as a base, fixing plates, and lens barrel. The image reading elements are fixed to a lens holding member with an attaching plate by using adhesive. The attaching plate has a position adjusting mechanism.

A stable, oil-in-water type, fine particle, fatty emulsion which is regulated with a pH value regulator consisting of an organic amine and a buffer solution to a pH value of 6.0 to 8.0, said fatty emulsion having a fatty particle size of not larger than 2.mu.. The fatty emulsion can stably be kept for a long period of time without lowering of the pH value and aggregation of the fatty particles.

A method for converting a multifilament bundle of a synthetic material into a sliver and an apparatus for effecting the method. The apparatus comprises: a feed roller device for feeding the bundle; a draft roller device consisting of a pair of draft rollers, the peripheral speed of which draft roller device is higher than that of the feed roller device, for stretch breaking the filaments in the bundle between the feed roller device and the draft roller device; and an apron belt, belted between one roller of the draft roller device and the intermediate portion of the feed roller device and the draft roller device, which is wound around the other draft roller. The broken filaments are smoothed between the apron belt and the other draft roller so that the evenness of the sliver thickness is improved and the uniformity in quality of the spun yarn obtained from the sliver is also improved. Accordingly, the method and apparatus has advantages when a multifilament bundle of a synthetic material is converted into a sliver at a high speed of not less than 200 m/min.

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.
