A scanning type projection exposure system includes a source emitting light. The light is applied to a portion of a mask having a preset pattern. At least one optical erect projection sub-system images a portion of the pattern on a substrate. The portion of the pattern corresponds to the portion of the mask exposed to the light. The projection sub-system is subjected to scanning movement. The mask and the substrate are subjected to scanning movement. Relative positions of the mask and the substrate are held fixed during the scanning movement of the mask and the substrate.

An original transfer apparatus used in an image-forming apparatus for forming an image in accordance with image information from an original set on an original table, whereby the original is transferred to the original table, is provided with a housing which is removably attached to the image-forming apparatus. The housing contains therein a transfer mechanism for swallowing and transferring the original to the original table. A drive source for driving the transfer mechanism is integrally provided in the housing. Since the drive source is contained in the housing, the original transfer apparatus can be mounted on the image-forming apparatus with ease.

摘要:
A silver halide color photographic light-sensitive material is disclosed. The material is comprised of a support having two layers thereon. One layer is comprised of a silver halide emulsion layer containing a non-diffusible coupler which couples with an oxidation product of a developing agent during development processing to form a dye of such mobility that controlled image smearing occurs. The other layer is comprised of a silver halide emulsion layer containing a polymer coupler latex which is adjacent to the emulsion layer containing the dye diffusion type coupler. By utilizing the silver halide color photographic light-sensitive material as disclosed within the application it is possible to obtain improved results with respect to the graininess and sharpness of the images produced with the material without having bad effects on other photographic properties of the material.
摘要:
In a method and an apparatus for detecting a sound source, a measurement plane to be observed is automatically scanned in two-dimensional manner by means of two microphones which are spaced apart from each other by a given distance and are moved by a traversing device. Outputs of these microphones are sampled for successive measurement regions and then are processed by processing circuit including a fast Fourier transform to derive acoustic intensities with respect to various frequencies in a given frequency range. Then, a distribution of the acoustic intensities is indicated on a display device by using various indication techniques. Therefore, since the measurement is effected by using the acoustic intensity representing both a sound power and a propagating direction, the analysis of the sound source can be performed in an easy and accurate manner, and an entier apparatus can be small in size and inexpensive in cost.
