摘要： A process for producing a polydiacetylene molecular orientated film is disclosed, which comprises a first step of forming a polydiacetylene film on a base using a diacetylene monomer or a polydiacetylene, a second step of unidirectionally rubbing the polydiacetylene film with a cloth at least once, a third step of building up a diacetylene monomer on the film, and a fourth step of polymerizing the diacetylene monomer film formed in the third step in a solid phase, said second to fourth steps being carried out once or more in this order. The resulting orientated film exhibits high orientation and crystallinity without limitations in film thickness, film area, and polymer materials.

摘要： Display systems, methods, and programs generate and display an arrow object superimposed on an actual image of a road ahead of a vehicle. The systems, methods, and programs access information about a lane change route for guiding the vehicle when changing from a travel lane to a recommended lane. The systems, methods, and programs generate and display a travel lane part of the arrow object, a crossing part of the arrow object, and a recommended lane part of the arrow object, each as a superimposed image on the recommended lane. As remaining distance from a current position of the vehicle to the junction becomes smaller, a distance of a directional component along the travel lane for at least one of the travel lane part, the crossing part, and the recommended lane part is shortened.

摘要： A polarizing beam-splitter comprises an optically isotropics crystalline substrate and a birefringent material layer made of an oriented polydiacetylene film formed on the optically isotropic crystalline substrate. A periodic grating photo-mask is formed in the birefringent material layer by an area that is changed into a different color phase when an ultra violet light is irradiated in a predetermined pattern on the birefringent material layer and by an area in which the color remains unchanged. The periodic grating photo-mask has a diffraction efficiency for the orientation of the oriented polydiacetylene film in the area that is changed into a different color phase which is lower than that in the area in which the color is unchanged.

摘要： Digital filters can be very effectively used for filtration of two-dimensional image. A special one of the digital filters operates to add together all data over a filter length, multiply the addition result by a predetermined set value, and to effect addition or subtraction between the multiplication result and data at a point of interest to be filtered. In case of the addition, the filter works as a low-pass filter. In case of the subtraction, the filter provides for a high-pass filtration. Such digital filter has such a problem that the number of additions is increased as the filter length is larger. Therefore, it is essential in the digital filters to reduce the necessary number of additions.

摘要： An X-ray radiograph apparatus comprising an X-ray source which irradiates a subject body with X rays of a low level radiation dose during the fluoroscopic operation and irradiates the same with X rays of a high level radiation dose during the radiographic operation; an X-ray image intensifier for converting an X-ray image, which has irradiated by the X-ray source and has penetrated through the subject body, into an optical image; a distributor for distributing an output optical image from the X-ray intensifier to a plurality of optical paths; a fluoroscopic imaging element arranged on one of plural output optical paths of the distributor; a radiographic imaging element arranged on an output optical path of the distributor other than the output optical path on which the fluoroscopic imaging element is arranged, the radiographic imaging element having a higher resolution than the fluoroscopic imaging element and having a lower imaging speed than the fluoroscopic imaging element; and an image display for displaying a fluoroscopic image or a radiographic image formed based on output signals from the fluoroscopic imaging element or the radiographic imaging element, respectively. With this, it becomes possible to collect, at the same time, the high resolution static image (radiographic image) by the radiographic imaging element and the moving image (fluoroscopic image) by the fluoroscopic imaging element. It is also possible to improve the S/N ratio of the radiographic image. Furthermore, should the radiographic image element include a defect pixel, the influence thereby would be lowered to minimum or to zero.
